background methicillin-resistant staphylococcus aureus (mrsa) remains a significant public health problem and treatment challenge. objectives this study was conducted to determine the frequency, molecular types, and drug resistance of s. aureus isolated from nasal carriers in two teaching hospitals (hajar and kashani) in shahrekord, southwestern iran. methods in this cross-sectional study, 262 ...

OBJECTIVES To assess the in vitro susceptibility of multidrug-resistant Enterobacteriaceae (MDRE) isolates to tigecycline. METHODS Clinical isolates of MDRE tested in this study were obtained from 91 hospitals in Belgium during the period January 2010 to April 2010. MICs of tigecycline were determined by Vitek 2 (VTK) and by the reference broth microdilution (BMD) method, and the results were...

Herein, we report the pathogenic and phylogenetic characteristics of seven Shiga toxin (Stx)-producing Escherichia coli (STEC) isolates from 434 retail meats collected in Korea during 2006 to 2012. The experimental analyses revealed that all isolates (i) were identified as non-O157 STEC, including O91:H14 (3 isolates), O121:H10 (2 isolates), O91:H21 (1 isolate), and O18:H20 (1 isolate), (ii) ca...

Campylobacter jejuni is one of the most common bacterial causes of human gastroenteritis, and recent findings suggest that turkeys are an important reservoir for this organism. In this study, 80 C. jejuni isolates from eastern North Carolina were characterized for resistance to nine antimicrobials, and strain types were determined by fla typing, pulsed-field gel electrophoresis (PFGE) with SmaI...

The genus Enterococcus can be found in water, soil, and food, above all, they are part of the animal (including human) intestinal microbiota. Food prevalence is mainly due to their resistance adverse environmental conditions. Seventy-three isolates from chicken viscera were confirmed belong by biochemical tests carbohydrate fermentation. Phenotypic characterization species indicates that E. cas...

The presence of Gram-negative bacteria in cuticle and alimentary tract of cockroaches collected from four selected areas of Dhaka city was investigated. Using detection key, a total of 12 cockroaches were identified as Periplaneta americana (58.33%), Blattella germanica (33.33%) and Blatta orientalis (8.33%). From these three species 54 different bacterial isolates were obtained. Out of them, 3...

Between 9 October and 12 November 1996, an outbreak of bloody diarrhea occurred in the neonatal nursery ward of the Policlínico Neuquén, in Neuquén, a city in the southwestern region of Argentina. Seven patients of the intermediate care unit were affected. Isolates of Escherichia coli O18ac:H31 that were non-lactose and -sorbitol fermenting were recovered from outbreak cases. Although the strai...

The antibiotic susceptibility of 125 P. aeruginosa isolated from 215 clinical samples (blood, urine, wound swab samples, sputum, and cerebrospinal fluid) was determined using the disk diffusion method on Muller-Hinton agar medium. results showed that isolates had a high resistance rate to carbenicillin (83.2%) piperacillin (76%). Resistance imipenem meropenem were 7.4% 14.8%, respectively, whil...

Geographic variation in drug susceptibility among isolates of Streptococcus pneumoniae has influenced national treatment guidelines for community-acquired pneumonia. Whether individual hospital susceptibility data provide reliable and valid information for providers is unclear. We examined the geographic and temporal variability in hospital-reported rates of pneumococcal susceptibility. We surv...

The AcrAB/TolC efflux pump-mediated drug resistance in gram-negative bacteria might be controlled by pump inhibitors (EPIs). This study was planned to discover a compound from plants that can used as an EPI. Forty isolates of K. pneumoniae and 33 different were collected. methanolic extracts parts prepared. Chloramphenicol, tetracycline, Ciprofloxacin for the sensitivity assay. Plant tested EPI...
