AIMS: To study the distribution and shifting trends of bacterial keratitis. METHODS: The data of 2220 corneal isolates from 1 January 1989 to 31 December 1998 were reviewed retrospectively. RESULTS: Positive culture was recovered in 490 isolates. Gram positive cocci and Gram negative bacilli represented 51% and 39.4%, respectively. Pseudomonas aeruginosa was the most common pathogen (32.2%). A gradual increase in the percentage of Gram positive cocci coupled with a decrease of Gram negative bacilli. CONCLUSION: Pseudomonas aeruginosa and coaculase negative Staphylococcus were the most common pathogens in bacterial keratitis in north China.  相似文献

BACKGROUND: The study shows differences between contact lens wearers and patients without history of contact lenses regarding the spectrum of etiological agents in bacterial keratitis. Based on microbiological analysis, there are given recommendations for an optimal initial antibiotic treatment in both groups. MATERIAL AND METHODS: From 1989 to 1997 smears, scrapings and corneal biopsies were taken from 218 patients with bacterial keratitis. The causing pathogens were isolated on directly inoculated culture media and identified by staining and microscopy. The resistance pattern of a total of 275 germs was analysed for different antibiotics. RESULTS: The most frequently isolated germs were Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus spp., Propionibacterium acnes and Pseudomonas aeruginosa. Whereas sensitive gram-positive germs were predominating in contact lens wearers as well as in non-contact lens wearers, multiresistant gram-negative germs could nearly exclusively be isolated from contact lens wearers. Frequently administered antibiotics like aminoglycosides and quinolones are effective in infections caused by Staphylococcus spp., but increasing resistance could be seen to Streptococcus spp. In this case, erythromycin is very sensitive. Gram-negative germs like Pseudomonas aeruginosa are sensitive to quinolones and some aminoglycosides (e.g. tobramycin). CONCLUSION: In contact lens wearers, more aggressive germs have to be considered than in non-contact lens wearers. In such cases, frequently administered antibiotics like amino-glycosides are not effective. To cover problematic gram-negative germs we recommend the application of quinolones alternating with erythromycin. The latter one is more effective than quinolones and aminoglycosides in case of Streptococcus spp. co-involvement.  相似文献

AIM: To analyze the epidemiological, clinical and laboratory findings of infectious keratitis. METHODS: A retrospective study on cases of infective keratitis, attended our institution from Mar. 2013 to Feb. 2015, was done at Mansoura Ophthalmic Center, Egypt. Corneal scrapings were performed and processed for direct microscopy and culture in appropriate media using standard laboratory protocols. RESULTS: Out of 245 patients enrolled for study, 247 corneal scrapings were obtained. Ocular trauma was the most common predisposing factor (51.4%), followed by diabetes mellitus (15.1%). Cultures were positive in 110 scraping samples (44.5%): 45.5% samples had pure fungal infection, 40% had pure bacterial infections and 10% had mixed fungal and bacterial growths. Acanthamoeba was detected in 5 (4.5%) samples. The most common fungal pathogen was Aspergillus spp. (41%). The most common bacterial isolates were Staphylococcus aureus (38.2%) and Pseudomonas aeruginosa (21.8%). CONCLUSION: Incidence of fungal keratitis is high in our region. Therapeutic approach can initially be based on clinical features and sensitivity/resistance patterns. Microbiological research should direct the antimicrobial treatment. Antibiotic resistance to fluoroquinolones and aminoglycosides is an important consideration.  相似文献

We report the first 2 cases of bacterial keratitis resistant to fourth-generation fluoroquinolones after laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). The first patient had Pseudomonas aeruginosa keratitis after PRK despite treatment with moxifloxacin. The second patient was on gatifloxacin post-LASIK when she had methicillin-resistant Staphylococcus aureus (MRSA) keratitis diagnosed. In both cases, culture susceptibilities showed isolates resistant to moxifloxacin and gatifloxacin, and treatment with topical aminoglycosides and surgical intervention was necessary to effect a cure. These cases show the potential limitations in the coverage of these antibiotics.  相似文献

Infectious keratitis in South Australia: emerging resistance to cephazolin   总被引:3,自引:0,他引:3  
PURPOSE: To analyze the microbiologic spectrum and patterns of resistance of infectious keratitis in patients treated at a tertiary hospital in South Australia. METHODS: Retrospective review of microbiology laboratory records of all patients with infectious keratitis who had corneal scrapings, from 1998 to 2003. All records were subsequently reviewed for Gram staining and culture results, as well as antibiotic sensitivity and resistance. RESULTS: Positive corneal cultures were obtained in 134 out of 211 patients who had corneal scrapings (63.5%). Coagulase negative Staphylococcus was the commonest pathogen identified (29.8% of positive cultures), followed by Staphylococcus aureus (18.7%), Pseudomonas aeruginosa (12.7%), Moraxella (6.7%), Streptococcus pneumonia (6.0%), and fungal keratitis (5.2%). In 43.3% of culture positive cases, the organisms were also identified in Gram stain, and in all these cases there was a full correlation between the two methods. In vitro sensitivities were highest for gentamicin. Fourteen cases (35%) of coagulase negative Staphylococcus were found to be resistant to cephazolin. No ciprofloxacin resistance was identified in all Pseudomonas isolates tested. CONCLUSIONS: Staphylococcus species continue to be the commonest causative organism for infectious keratitis; however, there is an emerging resistance to cephazolin, which is commonly used as the first-line antibiotic for Gram-positive cocci.  相似文献

OBJECTIVE: To study the distribution, current trends, and patterns of resistance to antimicrobial agents of bacterial keratitis isolates in South Florida. DESIGN: Retrospective, observational, case series. PARTICIPANTS: The microbiology records of all patients with bacterial keratitis seeking treatment at the Bascom Palmer Eye Institute from January 1, 1990 through December 31, 1998 were reviewed. MAIN OUTCOME MEASURES: In vitro laboratory minimum inhibitory concentration testing of the corneal isolates to the fluoroquinolones (ofloxacin and ciprofloxacin) and to the aminoglycosides (tobramycin and gentamicin) was performed using the Vitek (Automatic Microbial System Biomerieux Vitek, Inc., Hazelwood, Missouri) method. RESULTS: During this 9-year period, 2920 consecutive corneal cultures were obtained, and a pathogen was recovered in 1468 cultures (50%). The number of corneal ulcers scraped, positive cultures, recovered bacterial isolates, and ratio of gram-positive to gram-negative isolates per year remained approximately equal throughout the study period. Staphylococcus aureus and Pseudomonas aeruginosa represented 19.4% and 25.7%, respectively, of the total bacterial isolates during this period. However, we documented a gradual increase in the number of S. aureus keratitis isolates (29% of gram-positive organisms in 1990 versus 48% in 1998, P = 0.01) coupled with a decrease in the number of P. aeruginosa isolates (54% of gram-negative organisms in 1990 versus 46% in 1998). A decrease in the incidence of contact lens-associated keratitis and P. aeruginosa isolates in this group of patients was documented. Serratia marcescens and P. aeruginosa were most commonly isolated in contact lens-associated keratitis (18% each). There was increasing laboratory resistance of S. aureus keratitis isolates to the fluoroquinolones (11% in 1990 to 28% in 1998), but resistance patterns to the aminoglycosides remained unchanged. There was a three-fold increase in the percentage of resistant S. aureus isolates to fluoroquinolones between 1990 and 1994 and between 1995 and 1998. Both fluoroquinolones and aminoglycosides exhibited low in vitro effectiveness against P. aeruginosa throughout the study period. CONCLUSIONS: The increased recovery of S. aureus keratitis isolates and decreased laboratory effectiveness against fluoroquinolones to these pathogens present an important therapeutic challenge.  相似文献

PURPOSE: To determine the predisposing factors, demographic characteristics, and etiology of ulcerative keratitis in a referral center in Bangkok, Thailand. METHODS: The medical records of admitted patients with positive-culture ulcerative keratitis were retrospectively reviewed for demographic data, predisposing factors, and microbial culture results. Predisposing factors were compared between bacterial and fungal keratitis. RESULTS: From January 2001 to December 2004, there were 127 positive-culture ulcerative keratitis cases. The most frequent microbiological diagnosis was bacterial keratitis (76 eyes, 60%), followed by fungal (48 eyes, 38%) and Acanthamoeba keratitis (3 eyes, 2%). The most common organisms isolated were Pseudomonas spp. for bacteria and Fusarium spp. for fungus. Compared with bacterial keratitis, fungal keratitis was more likely to be associated with ocular trauma (odds ratio = 11.20; 95% confidence interval, 3.62-34.66) but less likely to be associated with contact lens wear (odds ratio = 0.02; 95% confidence interval, 0.01-0.08). CONCLUSIONS: In our study, Pseudomonas and Fusarium species are the most common causes of bacterial and fungal keratitis, respectively.

目的:对真菌性角膜炎患者的流行病学特征、实验室检查方法和结果及治疗效果进行分析,为真菌 性角膜炎诊治提供依据。方法: 回顾性系列病例研究。对2012年1月至2017年12月在冀中能源邢 台矿业集团总医院诊治的412例(412眼)真菌性角膜炎的流行病学特点、临床体征、病原学诊断方式、 结果及治疗效果采用Kruskal-Wallis H检验等统计学方法进行分析。结果:9-12月份是真菌性角膜 炎高发期,占全年患者总数的61.2%(252/412)。患病人群以农民为主,占59.5%(245/412),植物性 外伤为首要病因者185例(44.9%),其次为非植物性外伤86例(20.9%)。男女比例为1.82∶1。年龄 14~81(45.6±14.3)岁,41~60岁患者占53.9%(222/412)。真菌培养阳性率为88.8%(366/412),高 于氢氧化钾湿片法[77.2%(318/412)],2种检测方式比较差异有统计学意义(χ2 =31.14,P<0.001)。 前几位的致病菌依次是镰刀菌属167例(40.5%),链格孢菌属75例(18.2%),曲霉菌属62例(15.0%), 青霉菌属28例(6.9%)。真菌性角膜炎所致典型临床体征中以菌丝苔被最为常见(366例,88.8%), 其次为伪足(224例,54.4%)、前房积脓(111例,26.9%)。镰刀菌属、链格孢菌属、曲霉菌属及青 霉菌属所致真菌性角膜炎的病情分级和预后水平比较差异均有统计学意义(Hc=40.676,P< 0.001; Hc=40.109,P<0.001),显示镰刀菌属和曲霉菌属的病情分级重于链格孢菌属和青霉菌属,预后水平 也差于链格孢菌属和青霉菌属。结论:真菌性角膜炎患者呈逐年增多趋势;氢氧化钾湿片法和真菌 培养都是有效的诊断方法,镰刀菌属和曲霉菌属所致的真菌性角膜炎较链格孢菌和青霉菌引起的真 菌性角膜炎病情相对较重,且预后较差。  相似文献
