BACKGROUND/AIMS Recent evidence has suggested that appendix plays a pivotal role in the development and preservation of intestinal immune system. The aim of this study is to examine whether prior appendectomy is associated with an increased risk for the development of antibiotic-resistant bacteria in bacteremia from biliary tract infection (BTI). METHODS Charts from 174 consecutive cases of b...
Brown, Ruby L. (North Carolina State College, Raleigh) and James B. Evans. Comparative physiology of antibiotic-resistant strains of Staphylococcus aureus. J. Bacteriol. 85:1409-1412. 1963.-A collection of antibiotic-resistant strains of Staphylococcus aureus isolated from clinical sources was studied with respect to nutritional requirements and common diagnostic tests. Contrary to numerous rep...
Antibiotic resistance and associated genes are ubiquitous and ancient, with most genes that encode resistance in human pathogens having originated in bacteria from the natural environment (eg, β-lactamases and fluoroquinolones resistance genes, such as qnr). The rapid evolution and spread of "new" antibiotic resistance genes has been enhanced by modern human activity and its influence on the en...
The goal of this study was to follow ceftiofur-treated and untreated cattle in a normally functioning dairy to examine enteric Escherichia coli for changes in antibiotic resistance profiles and genetic diversity. Prior to treatment, all of the bacteria cultured from the cows were susceptible to ceftiofur. Ceftiofur-resistant E. coli was only isolated from treated cows during and immediately fol...
The present study investigates the prevalence of antibiotic resistance among bacterial isolates from different environmental samples and determines their resistance patterns. Bacteria were isolated from the Ganges water, the intestine of Labeo rohita, soil samples from agricultural land, and clinical samples of urine, pus, and throat swab. The bacterial isolates were identified on the basis of ...
background and objectives: the prevalence of vibrio parahaemolyticus has been reported from ponnani earlier, however incidence of multidrug resistant strains have been encountered recently in clinical laboratories. the source for such strains and their presence in this major fish landing centre has been investigated. materials and methods: antibiotic sensitivity tests on isolates of v. parahaem...
abstract background and objective: one of the main tasks of clinical microbiology laboratories is to determine antibiotic resistance profiles in common pathogens and ensure the selection of effective antibiotics for certain infections. the aim of this study was to compare the methods of disk diffusion, broth microdilution and modified hodge test in escherichia coli isolates from urinary...
background: resistant strains of pseudomonas aeruginosa to imipenem was medical treatment problem, especiallyin burnt units of hospitals. objectives: this study was conducted to evaluate the antimicrobial effect of fe2o3 nanoparticles alone and functionalized with imipenem on p. aeruginosa starins producing metallo b-lactamases (mbl).materials and methods: a disk diffusion method was used to is...
A total of 38 Staphylococcus aureus were isolated from mobile phone devices used by ready-to-eat food seller, diagnostic laboratory technician and day-care centre staff. To reveal the antibiotic resistance profile, the isolates were subjected to antibiogram study against nine antibiotics. The study revealed that 68.42% of the S. aureus isolates were resistant to at least one of the antibiotics ...
