Neonatal septicaemia (NNS) is a major cause of neonatal morbidity and mortality. Neonatal septicaemia was studied to determine the incidence, common bacterial aetiology and antibiotic susceptibility in Qatif Central Hospital, Saudi Arabia. Of 1,797 babies admitted into the unit over a 3 year period, 144 (8.0%) had documented neonatal septicaemia consisting of 94 (65%) late onset and 50 (35%) early onset septicaemia. The incidence was 8.2/1000 of the total live births in the hospital.
Gram negative bacteria were encountered in 66.2%, gram positive bacteria in 29.2% and Candida albicans in 4.4% of the case. Klebsiella spp., E. coli, and Pseudomonas accounted for 81.8 % of the gram negative while Staphylococcus epidermidis, Staphylococcus aureus and group B Beta haemolytic Streptococcus accounted for 73.9% of the gram positive bacteria.
Most of Gram negative bacteria had a high sensitivity to Aminoglycosides and third generation Cephalosporins. Coagulase negative staphylococci were frequently resistant to most antibiotics but always sensitive to Vancomycin. The overall mortality rate was 18.7%. 相似文献

The concentration of plasma fibronectin was determined by Laurell's electroimmunoasay [15] in 75 preterm or term newborns within the first 2 days of life, in 97 healthy infants aged from 3 days to 12 months, in 40 septic infants and in 38 healthy adult subjects. The mean fibronectin concentration in citrated plasma of normal adults was 318±84 ml/l. Healthy eutrophic term newborns 1–2 days old had approximately one-third of the fibronectin concentration of adults. There was no significant difference in the values between healthy term and eutrophic preterm newborns or between eutrophic and hypotrophic newborns. The plasma fibronectin increased strongly over the 1st month of life. No significant difference was observed between fibronectin levels in infant boys and girls. The values in septic newborns and septic older infants were significantly lower when compared with those of age-matched healthy controls. It is speculated that this deficiency, because of linkage to fibrin in disseminated intravascular coagulation or due to increased utilisation as a non-specific opsonin and sequestration at sites of tissue injury, may contribute to organ failure in septicaemia.Abbreviations SB

A survey of bloodstream infections was conducted in the large regional hospital in Ubon Ratchatani, northeastern Thailand between 1989 and 1998, during the onset of the HIV epidemic. The incidence of Staphylococcus aureus, Escherichia coli, Klebsiella/Enterobacter and Pseudomonas aeruginosa bacteraemias remained constant whereas infections caused by Burkholderia pseudomallei, non-typhoid Salmonellae, Cryptococcus neoformans, Penicillum marneffei and to a lesser extent Streptococcus pneumoniae all rose. Burkholderia pseudomallei infections were unrelated to HIV, whereas the other infections were associated directly with HIV. Group D non-typhoid Salmonellae bloodstream infections (mainly Salmonella enteritidis) rose coincident with the increase in HIV seroprevalence, and preceded the increase in the other HIV-associated infections. Other non-typhoid Salmonella bacteraemias increased two years after the rise in group D infections, and invasive yeast infections increased four years later, coincident with the increase in AIDS. Increasing Group D non-typhoid Salmonella bloodstream infections are an early warning signal of an impending rise in AIDS. 相似文献

ABSTRACT. The incidence of neonatal septicaemia associated with prolonged rupture of foetal membranes, discoloured amniotic fluid and/or maternal fever was investigated. A total of 807 blood cultures were performed on 329 neonates, the placental end of 239 umbilical cords and on 239 mothers. The study showed that in 97% of the neonates with a complicated delivery there was no evidence of septicaemia. Septicaemia was verified in 3% of the infants, and was intimately associated with low birth weight (p = 0.02), neonatal asphyxia (p < 10-4 ) clinical evidence of septicaemia (p < 10-4 ) and maternal fever(p = 0.002). The incidence was particularly high in premature infants with neonatal asphyxia (27%) and in neonates born to febrile mothers (20%). None of the mothers showed any evidence of septicaemia, and haematogenous, transplacental spread of infection to the child was not seen. Routine prophylactic antibiotic therapy in neonates with a complicated delivery should therefore be reserved, in our opinion, for those infants at high risk of infection. 相似文献

Many countries have been experiencing a significant increase in meningococcal disease. With the strains currently circulating, septicaemia is now a more frequent manifestation than meningitis and early recognition of disease manifestations by patient, parent or physician as well as early recognition of disease severity are the most important factors in attempting to reduce mortality and morbidity. Ceftriaxone is the treatment of choice but must be accompanied by aggressive supportive therapy in those with severe disease. The role of steroids is unknown. The evidence to support their use in both meningitis and severe systemic sepsis is discussed. The purified polysaccharide vaccines that have been available for some years may play a limited role in disease prevention. The recently introduced conjugate vaccine for preventing serogroup C disease represents a major advance but no vaccine is currently available to prevent serogroup B disease, cases of which will continue to challenge clinical practice. 相似文献

Neonatal infections may be caused by various microorganisms, but as far as we are aware, Acinetobacter ursingii has not yet been reported in connection with nosocomial infections of premature infants. During 2 months, 3 premature babies were treated with nosocomial infection caused by A. ursingii at the same ward, and on the basis of molecular typing results the same strain was responsible for all of these cases. Traditional biochemical methods and automatic identification systems failed to identify this bacterium on the species level, and only 16S rDNA sequencing gave acceptable species identifications. The isolated strains proved to be susceptible to all of the tested antimicrobials, including ampicillin/sulbactam, doxycyclin, netilmicin, ciprofloxacin, piperacillin/tazobactam, ceftazidime, imipenem, meropenem, trimethoprim/sulfametoxazole, gentamicin, tobramycin, amikacin, and levofloxacin according to the CLSI standard. In spite of the environmental screening, the source of the infection could not be clarified. One of 3 neonates died, the others recovered and were discharged home after several months of hospitalization. 相似文献

Blood cultures were obtained from 39% of all 574 admissions to our Medical Intensive Care Unit (ICU); in 109 (19%) a pathogenic organism was demonstrated. 45% of the septicaemias were detected within the first 48 h of ICU stay and have been considered as non ICU-acquired. Septicaemic patients were significantly older, had longer ICU stays and a higher mortality rate (62%) than non septicaemic patients (28%) (p<0.05). Gram negative organisms (69%) predominated over gram positive (29%) andSerratia marcescens and coagulase positiveStaphyloccoccus were the most frequently isolated. Shock appeared in 32% and had an extremely high mortality (91%) and was associated with the presence of multiple species septicaemia. Prior to the septicaemia the survivors differed from the fatalities only in the level of serum albumin; this was significantly lower in patients with gram negative in comparison with gram positive septicaemias and in patients who developed shock. Arterial, pulmonary artery and urinary catheters, and endotracheal devices were used frequently in these patients and were statistically associated with the presence of septicaemia. The airway was the most frequent possible source for the septicaemia. 相似文献
