Excretion of enrofloxacin in pigs and its effect on ecological environment

The concentration of enrofloxacin and its metabolite, ciprofloxacin, in feces and urines were investigated in healthy pigs after oral administration (p.o.) of a single dose of 5.0 mg/kg bw and an indoor soil model was set to study the effects of enrofloxacin and ciprofloxacin through biological and chemical metrics including changes to edaphon, edaphic ammonification and nitrification and the soil bacterial community. The results showed that the concentrations of entofloxacin and ciprofloxacin in feces and urines fluctuated, the maximum concentrations of enrofloxacin and ciprofloxacin in the urine were 22.74 and 48.04 μg/ml, respectively, 24.68 and 30.98 μg/g in the feces, respectively. The effect of enrofloxacin and ciprofloxacin on edaphon, edaphic ammonification and nitrification and the soil bacterial community differed at different time points. And the model can be used to evaluate environmental safety of enrofloxacin and develop possible procedures for the safe handling and utilization of animal excrement.

Simultaneous extraction of enrofloxacin and ciprofloxacin from chicken tissue by molecularly imprinted matrix solid-phase dispersion

An ofloxacin molecularly imprinted polymer was synthesized and used as a dispersant of matrix solid-phase dispersion for the determination of enrofloxacin and ciprofloxacin in chicken tissue. The selected dispersant shows high affinity to enrofloxacin and ciprofloxacin in aqueous environment and could selectively enrich them from chicken tissue matrix. The extract was sufficiently clean for further chromatographic analysis without interferences from template leakage or chicken tissue matrix. Linearity ranged from 0.03 to 200 μg/g with the correlation coefficient r² > 0.9993. The recoveries of spiked chicken tissues were in the range of 82.7–96.6% for enrofloxacin and 88.7–102% for ciprofloxacin.     

Effects of aflatoxin B1 on tissue residues of enrofloxacin and its metabolite ciprofloxacin in broiler chickens

The impact of subchronic exposure of aflatoxin B1 on the tissue residues of enrofloxacin and its metabolite ciprofloxacin was examined in broiler chickens. Broiler chickens given either normal or aflatoxin B1 (750 μg/kg diet) supplemented diets for 6 weeks received enrofloxacin (10 mg/kg/day, p.o.) for 4 days and thereafter, residue levels were determined. Aflatoxin B1 induced alterations in serum marker enzymes. As compared to unexposed broiler chickens, enrofloxacin concentrations in aflatoxin B1-exposed broiler chickens were significantly higher in all tissues (0.62-4.53 μg/g) analyzed except muscle 24h after termination of enrofloxacin administration. Ciprofloxacin was detectable in tissues of only mycotoxin-exposed broiler chickens. Enrofloxacin residues in liver, kidney and skin plus fat persisted for 10 days in mycotoxin-exposed broiler chickens whereas it was detectable only in liver of unexposed broiler chickens. Our results indicate that subchronic aflatoxin B1 exposure markedly influences the residue levels of enrofloxacin and ciprofloxacin in tissues of broiler chickens.     

Post-exposure therapy of inhalational anthrax in the common marmoset

The aim of this study was to compare the pharmacokinetics and efficacy of ciprofloxacin as post-exposure therapy against inhalational anthrax in the common marmoset (Callithrix jacchus) with other non-human primate models in order to determine whether the marmoset is a suitable model to test post-exposure therapies for anthrax. Pharmacokinetic (PK) and efficacy studies with ciprofloxacin were performed in the marmoset. Ciprofloxacin plasma pharmacokinetics were determined in six animals in separate single-dose and multiple-dose studies and were analysed by high-performance liquid chromatography (HPLC). A separate group of marmosets was exposed to ca. 100× the 50% lethal dose (LD₅₀) of Bacillus anthracis Ames strain by the airborne route. On Day 5 of a twice-daily dosing regimen of 17.5 mg/kg, the ciprofloxacin half-life (t_1/2), maximum drug concentration (C_max) and area under the concentration-time curve (AUC) in marmoset plasma were 1.9 h, 2.1 μg/mL and 7.9 μg/mL/h, respectively. Naïve untreated control animals succumbed to infection by Day 9. All animals treated with ciprofloxacin, started on the day of exposure and continued for 10 days, remained healthy during the treatment period. Two antibiotic-treated animals (33%) died after withdrawal of antibiotic therapy, attributed to the germination of residual spores. In conclusion, in many respects the marmoset appears to respond to B. anthracis in a similar way to the macaque, suggesting that this small non-human primate is an acceptable, practical alternative model for the evaluation of medical countermeasures against respiratory anthrax infection.     

Effects of some quinolone antibiotics on malondialdehyde levels and catalase activity in chicks

In this study, the effects of enrofloxacin, ciprofloxacin and norfloxacin at therapeutic doses and over therapeutic periods on plasma malondialdehyde (MDA) levels and erythrocyte catalase (CAT) activity were investigated. For this purpose, a hundred and sixty 3-day-old female Ross breed broiler chicks were used. Four groups, each comprising 40 were established. While group 1 was maintained as control, groups 2, 3 and 4 were administered enrofloxacin, ciprofloxacin and norfloxacin, respectively, at 10 mg/kg bw/day in drinking water. On days 1, 3, 5 and 7, ten animals were killed from each group, and plasma MDA levels and erythrocyte CAT activity were measured spectrophotometrically. The data obtained demonstrated that CAT activity was statistically decreased in groups 2 and 4, and increased in group 3 on day 1. In conclusion, it was determined that neither of the three drugs generated free radicals, in other words, caused lipid peroxidation physiologically when given at therapeutic dosage.     

Inhibitory activity of quercetin and its metabolite on lipopolysaccharide-induced activation of macrophage U937 cells

The potential of quercetin and its metabolite 3-O-methyl quercetin in inhibiting lipopolysaccharide (LPS)-mediated activation of macrophage U937 cells was investigated. Cells were pre-incubated for different periods with 100 ng/mL phorbol myristate acetate (PMA), and later with LPS and quercetin or 3-O-methyl quercetin (30 μM). Later, the supernatant of each cell culture was assessed for catalase activity, nitric oxide, and the production of tumour necrosis factor-α (TNF-α), interleukin 6 (IL-6), and interleukin 1 (IL-1). The results showed that when the cells were incubated with LPS, there were elevations in the levels of all the markers over the cells not incubated with LPS (P < 0.05). For the cells that were incubated with LPS, there were significant differences between the various cells when they were pre-incubated with PMA for various periods (P < 0.05). However, greatest production of the markers was attained when the cells were pre-treated with PMA for 48 h. Both quercetin and 3-O-methyl quercetin (at 30 mM) reduced the levels of all the markers with 3-O-methyl quercetin possessing more inhibitory potential (P < 0.05). This suggests that the flavonoids possessed significant immunomodulatory activities which depend on methylation especially at position 3.     

Evaluation of the immunogenicity and in vivo toxicity of the antimicrobial peptide P34

Immunogenicity and toxicity of antimicrobial peptide P34 were evaluated in vivo. BALB/c mice were inoculated intraperitoneally with peptide P34 alone and associated with Freund's adjuvant. For acute toxicity testing, different concentrations of the peptide P34 (82.5, 165.0, 247.5 and 330.0 mg/kg) were orally administered. To evaluate the sub-chronic toxicity the tested dose of 0.825 mg/kg/day of the peptide P34 or nisin were administered for 21 days. There were no hypersensitivity reactions or significant increase in antibody titer during the immunogenicity experiment or death of animals during the acute or sub-chronic toxicity tests. The LD₅₀ was higher than 332.3 ± 0.76 mg/kg. No significant changes in serum biochemical parameters were observed in the animals treated with the peptide P34 unlike nisin-treated group showed a significant increase in alanine transaminase levels in comparison to controls. The group treated with 0.825 mg/kg/day of nisin showed histological changes in the spleen, skin and liver. In the group treated with peptide P34 histological changes in the spleen were observed, with the presence of megakaryocytes. Few studies report the use of animal models to evaluate the in vivo toxicity of antimicrobial peptides and such investigation is an essential step to ensure it safe use in foods.     

Bioavailability of Enrofloxacin after Oral Administration to Fed and Fasted Pigs

Abstract: The disposition of enrofloxacin was measured after intravenous and oral administration to pigs. Eight clinically healthy pigs weighing 25 to 40 kg received a dose of 5 mg/kg intravenously and 10 mg/kg orally in both a fasted and a fed condition in a three-way cross-over design. Enrofloxacin was present in plasma for up to 72 hr after both intravenous and oral administration to fasted as well as fed pigs. The steady state volume of distribution was determined to 3.9±0.5 1/kg body weight which indicates that enrofloxacin was widely distributed in the body. The bioavailability was determined to 83±13% in fed and to 101±32% in fasted pigs. Based on the bioavailability and the resulting plasma concentrations it is concluded that a therapeutically active concentration for the most common porcine microbial pathogens are maintained for at least 24 hr after oral administration of 10 mg/kg body weight to fasted as well as to fed pigs. Ciprofloxacin which is an active metabolite of enrofloxacin was observed in plasma samples from all treated pigs, but the concentration never exceeded 0.1 μg/ml. During the first 24 hr after the administration of enrofloxacin the concentration of the metabolite made up less than 10% of the corresponding concentration of the parent compound.     

Simple, rapid determination of enrofloxacin and ciprofloxacin in bovine milk and plasma by high-performance liquid chromatography with fluorescence detection

A rapid and simple procedure for determination of enrofloxacin and ciprofloxacin in bovine milk and plasma is described. Protein precipitation from both milk and plasma samples was achieved by addition of acetonitrile and phosphoric acid. Acetonitrile was removed with methylene chloride, leaving enrofloxacin and ciprofloxacin in the acidic aqueous extract. The aqueous extract was analyzed by high-performance liquid chromatography (HPLC) with fluorescence detection. The limit of quantitation (LOQ) for enrofloxacin and ciprofloxacin in milk was found to be 2ng/ml. LOQ for enrofloxacin and ciprofloxacin in plasma was found to be 1ng/ml. Linear calibration curves were obtained with correlation coefficient (r(2)) >/=0.99. Analysis of quality control (QC) samples gave results within +/-10% of the nominal values. Inter-assay precision for the analysis of milk QC samples were in the ranges: 4.63-12.49% (for enrofloxacin) and 4.67-9.86% (for ciprofloxacin). Inter-assay precision for the analysis of plasma QC samples were in the ranges: 6.60-17.31% (for enrofloxacin) and 6.14-13.87% (for ciprofloxacin). Intra-assay precision for the analysis of milk QC samples were in the following ranges: 3.65-7.21% (for enrofloxacin) and 1.58-14.28% (for ciprofloxacin). Intra-assay precision for the analysis of plasma QC samples were in the following ranges: 2.17-16.95% (for enrofloxacin) and 3.31-16.31% (for ciprofloxacin). The effectiveness of protein precipitants other than phosphoric acid was investigated. The method described has been applied to a study of the pharmacokinetics of enrofloxacin and ciprofloxacin in lactating dairy cows and beef steers.     

Oxidative stress and immunotoxic effects of lead and their amelioration with myrrh (Commiphora molmol) emulsion

The possible role of Commiphora molmol emulsion (CME) in protecting against lead (PbAc)-induced hepatotoxicity, oxidative stress and immunotoxicity in rabbits was assessed. Six groups of animals were used: groups I (control) and II (PbAc) were not supplemented with CME. Groups III (CME50) and IV (CME50 + PbAc) were administered with CME in a dose rate of 50 mg/kg bwt, while groups V (CME100) and VI (CME100 + PbAc) were received 100 mg CME/kg bwt daily p.o for successive 14 weeks. Groups II, IV and VI were given 80 mg PbAc/kg bwt/day orally for 6 weeks starting from the 9th week. At the 12th week, animals were subjected to immunization by a single dose of sheep RBCs. The PbAc-group showed 220% increase in hepatic malondialdehyde levels, while glutathione, glutathione s-transferase and glutathione peroxidase levels decreased. Lead-acetate induced hypoproteinemia and hypoalbuminemia, and increased aminotransferases activity. It reduced the values of lymphocyte transformation test, phagocytic activity, phagocytic index and antibody titer against sheep SRBCs. Interestingly, pretreatment with CME attenuated these adverse effects in a dose-dependent protection. CME, therefore, is a potent antioxidant, and can protect against PbAc-induced hepatic oxidative damage and immunotoxicity by reducing lipid peroxidation and enhancing the antioxidant and immune defense mechanisms.     

Changes of metabolic profiles in urine after oral administration of quercetin in rats

Quercetin has been studied extensively. However, its actions in vivo are not well understood. We investigated the overall metabolic changes in urine after oral quercetin administration in rats and try to provide useful information on the actions of quercetin in vivo. Rats were orally administered a single dose of quercetin aglycon (40 mg/kg body weight). Urine samples were collected and subjected to ¹H nuclear magnetic resonance (NMR)-based metabolomic analysis and high performance liquid chromatography–mass spectrometry (HPLC–MS). Significant changes of metabolic profiles were observed in urine after quercetin administration. Relative increase in the concentrations of choline, creatinine, dimethylglycine, hippurate, taurine, trimethylamine N-oxide and reduction in acetate, alanine, lactate were observed. The concentrations of citrate, 2-oxoglutarate and succinate increased in the 0–24 h period after treatment and decreased thereafter. Some peaks assignable to quercetin metabolites were found in the aromatic regions of ¹H NMR spectra. HPLC–MS analysis identified quercetin, methyl quercetin, quercetin sulfate, quercetin monoglucuronide, and methyl quercetin monoglucuronide in urine after administration of quercetin. Our current findings indicate that quercetin behaves not only as an antioxidant, but also a modulator for some metabolic processes in vivo. The active forms of quercetin present in the biofluids must be investigated further.     

Determination of fluoroquinolones in chicken feces – A new liquid–liquid extraction method combined with LC–MS/MS

The application of antibiotics including fluoroquinolones to farming animals is widespread and may lead to the development of antibiotic resistance and other environmental effects. To calculate environmental loads and for a proper risk assessment it is necessary to determine the antibiotic concentration in feces. Therefore, a new liquid–liquid extraction method combined with HPLC–MS/MS for the detection of marbofloxacin, ciprofloxacin, enrofloxacin and difloxacin in chicken feces was developed. Recoveries ranged from 51.0% to 83.5%. LOQs were between 0.10 and 1.09 μg/kg. Feces of chickens treated with an enrofloxacin dosage of 10 mg/kg bodyweight revealed maximum enrofloxacin and ciprofloxacin concentrations of 61.3 and 18.8 mg/kg. Both antibiotics could be detected in feces up to two days after the last application in notable amounts (∼1 mg/kg). Thus, feces of recently medicated chickens should not be used as a fertilizer without any further processing.     

Safety evaluation of an açai-fortified fruit and berry functional juice beverage (MonaVie Active)

The safety of an açai (Euterpe oleracea Mart.) pulp enriched fruit and berry juice, MonaVie Active^®, fortified with the functional ingredient, glucosamine, was studied. The beverage was found not to be mutagenic, clastogenic, cytotoxic, or genotoxic, as determined by the bacterial reverse mutation assay, chromosomal aberration assay, mouse micronucleus assay, and mammalian cell gene mutation (L5178Y) assay. The single dose LD50 based on a 14-day acute oral toxicity study is greater than 20,000 mg/kg bw, the highest dose tested. In a repeat dose 90-day oral subchronic toxicity study by gavage, 220 animals were randomly assigned to a control group, an untreated group, or one of three experimental groups (10, 20 and 40 g/kg bw). No treatment-related significant changes in body weight, food and water consumption, ophthalmology, organ weights, urinanalysis, hematological and clinical chemistry, or gross pathology, were observed in surviving animals compared to the control groups. Three animals died midway through the observation period (male, 20 g/kg bw/day; male 40 g/kg bw/day; and, female, 10 g/kg bw/day). These animals died without preceding clinical symptoms, histopathological lesions, or evidence of injury to tissue or organs except for signs of suffocation/aspiration congestion, which was concluded to be due to problems with the gavage administration of the fluid test article, and not due to the test article itself. The NOEAL was determined to be 40 g/kg bw/day for male and female rats, which was the highest dose tested. Phylloquinone (vitamin K1) content averaged 21.7 μg/100 g, comparable to amounts found in iceberg lettuce. In conclusion, the results provide additional experimental evidence that MonaVie Active^® juice is non-toxic.     

Urinary and amniotic fluid levels of phthalate monoesters in rats after the oral administration of di(2-ethylhexyl) phthalate and di-n-butyl phthalate

Two studies were designed to examine amniotic fluid and maternal urine concentrations of the di(2-ethylhexyl) phthalate (DEHP) metabolite mono(2-ethylhexyl) phthalate (MEHP) and the di-n-butyl phthalate (DBP) metabolite monobutyl phthalate (MBP) after administration of DEHP and DBP during pregnancy. In the first study, pregnant Sprague-Dawley rats were administered 0, 11, 33, 100, or 300 mg DEHP/kg/day by oral gavage starting on gestational day (GD) 7. In the second study, DBP was administered by oral gavage to pregnant Sprague-Dawley rats at doses of 0, 100, or 250 mg/kg/day starting on GD 13. Maternal urine and amniotic fluid were collected and analyzed to determine the free and glucuronidated levels of MEHP and MBP. In urine, MEHP and MBP were mostly glucuronidated. By contrast, free MEHP and free MBP predominated in amniotic fluid. Statistically significant correlations were found between maternal DEHP dose and total maternal urinary MEHP (p=0.0117), and between maternal DEHP dose and total amniotic fluid MEHP levels (p=0.0021). Total maternal urinary MEHP and total amniotic fluid MEHP levels were correlated (Pearson correlation coefficient=0.968). Statistically significant differences were found in amniotic MBP levels between animals within the same DBP dose treatment group (p<0.0001) and between animals in different dose treatment groups (p<0.0001). Amniotic fluid MBP levels increased with increasing DBP doses, and high variability in maternal urinary levels of MBP between rats was observed. Although no firm conclusions could be drawn from the urinary MBP data, the MEHP results suggest that maternal urinary MEHP levels may be useful surrogate markers for fetal exposure to DEHP.

Synergistic action of quercetin and murine alpha/beta interferon in the treatment of Mengo virus infection in mice

ABD2F1 mice were infected intraperitoneally (i.p.) or intranasally (i.n.) with Mengo or Sindbis virus and treated with either crude murine alpha/beta interferon (MuIFN-alpha/beta) or quercetin, or both. MuIFN-alpha/beta given i.p. or intramuscularly (i.m.) 1-3 h before the infection had a dose-dependent protective effect regardless of the route of administration. When given after the infection, IFN did not show any effect. Oral quercetin, capable of protecting cardio, i.e. Mengo virus-infected mice, failed to show antiviral efficacy in Sindbis virus-infected animals. Of various combinations of quercetin and MuIFN-alpha/beta, a certain well defined regimen resulted in a significant enhancement of protection in Mengo, but not Sindbis, virus-infected mice. A marginally effective treatment regimen of quercetin (20 mg/kg, given 12 h before Mengo virus infection, and 10 mg/kg given both 1 h before and 12 h after infection) potentiated the activity of a single dose of MuIFN-alpha/beta (5000 IU 3 h prior to infection), giving 85-100% survivors compared to 50% for MuIFN-alpha/beta when applied alone (p less than 0.001).     

Whole body radioprotective activity of an acetone–water extract from the seedpod of Nelumbo nucifera Gaertn. seedpod

Procyanidins extracted with acetone–water from lotus (Nelumbo nucifera Gaertn.) seedpod (LSPCs) were evaluated for in vivo radioprotective activity against whole body gamma irradiation in Swiss albino mice. Pretreated with LSPCs 200 mg/kg by intragastric (i.g.) for 15 days was found to be the most effective dose in preventing radiation sickness, reducing radiation-induced mortality, increasing mean survival time and elevating radiation median lethal dose (LD₅₀) from 8.9 to 10.5 Gy, indicating a dose modifying factor (DMF) of 1.18. Further, administered LSPCs at a dose of 200 mg/kg could effectively maintain spleen index close to normal, stimulate endogenous spleen colony forming units, promote the levels of red blood cells (RBC), white blood cells (WBC), platelets and hemoglobin in peripheral blood, and prevent spleen and skin damage in irradiated mice, reduce the level of radiation-induced micronucleated polychromatic erythrocytes in bone marrow, maintain the polychromatic erythrocytes (PCE) and normochromatic erythrocytes (NCE) ratio (P/N ratio) and significantly decrease bone marrow chromosomal damage. Alternatively, pretreated with LSPCs (200 mg/kg) significantly decreased the lipid peroxidation (LPO) level, and elevated the activities of endogenous antioxidant enzymes in liver after irradiation. Thus LSPCs possess a strong whole body radioprotective activity, and it may be used as a radioprotector.     

Synergistic neurotoxicity induced by methylmercury and quercetin in mice

Methylmercury (MeHg) is a highly neurotoxic pollutant, whose mechanisms of toxicity are related to its pro-oxidative properties. A previous report showed under in vivo conditions the neuroprotective effects of plants of the genus Polygala against MeHg-induced neurotoxicity. Moreover, the flavonoid quercetin, isolated from Polygala sabulosa, displayed beneficial effects against MeHg-induced oxidative damage under in vitro conditions. In this study, we sought for potential beneficial effects of quercetin against the neurotoxicity induced by MeHg in Swiss female mice. Animals were divided into six experimental groups: control, quercetin low dose (5 mg/kg), quercetin high dose (50 mg/kg), MeHg (40 mg/L, in tap water), MeHg + quercetin low dose, and MeHg + quercetin high dose. After the treatment (21 days), a significant motor deficit was observed in MeHg + quercetin groups. Biochemical parameters related to oxidative stress showed that the simultaneous treatment with quercetin and MeHg caused a higher cerebellar oxidative damage when compared to the individual exposures. MeHg plus quercetin elicited a higher cerebellar lipid peroxidation than MeHg or quercetin alone. The present results indicate that under in vivo conditions quercetin and MeHg cause additive pro-oxidative effects toward the mice cerebellum and that such phenomenon is associated with the observed motor deficit.     

In vitro antioxidant and in vivo anti-inflammatory potential of crude polysaccharide from Turbinaria ornata (Marine Brown Alga)

Water-soluble crude polysaccharide from a brown alga Turbinaria ornata (TCP) was screened for its antioxidant and anti-inflammatory potential. The major functional groups of polysaccharide were analyzed by Fourier Transmission-Infra Red (FT-IR). In vitro free radical quenching and total antioxidant activity of TCP was investigated by 1, 1-diphenyl-2-picryl hydrazyl (DPPH), nitric oxide (NO) scavenging, lipid peroxidation (LPO) inhibition and ABTS radical assay. Evaluation of anti-inflammatory activity of TCP was performed using carrageenan-induced paw edema in rats and vascular permeability test in mice. Phytochemical analysis of TCP showed the presence of carbohydrates, proteins and polyphenols further, the FT-IR analysis of TCP showed the presence of functional groups of sugar moiety, uronic acids and sulfate groups. TCP showed maximum LPO, NO and DPPH inhibition of 78.04%, 38.82% and 80.21% at a concentration of 1000, 125 and 500 μg/ml respectively. Oral administration of TCP (2.5, 5, 10, 20 mg/kg) reduced the paw edema considerably (p < 0.05) in a dose dependent manner compared to carrageenan induced rats. Similarly, oral administration of TCP (3, 10, 30 mg/kg) evoked a significant (p < 0.05) dose dependent inhibitory effect on vascular permeability in mice. Altogether, these results suggest that the crude polysaccharide of T.ornata could be considered as a potential antioxidant and anti-inflammatory agent.
