INTRODUCTION : Identification of virulence determinants among the clinically isolated microorganisms assumes greater significance in the patient management perspective. Among the hospitalized patients, extremes of age groups (neonatal and geriatric age patients), patients who are debilitated due to other associated medical conditions, patients taking immunosuppressive therapy, and patients unde...

conclusions our findings suggested a worrying increase in resistance of v. cholerae strains to commonly used antibiotics. differences in patterns of resistance between afghan and iranian patients' samples were observed, which further emphasize a need for constant observation. results a st revealed high levels of resistance to sulfamethoxazole-trimethoprim (89.6%), tetracycline (60.4%), ampicill...

conclusions the results of this study indicated that the genes encoding aminoglycoside-modifying enzymes are prevalent in a. baumannii isolates in the study region, which highlighted the necessity of considering preventive measures to control dissemination of these resistance genes. results antimicrobial susceptibility analysis showed that the highest resistance was towards beta−lactam antibiot...

Shigella sonnei is a significant cause of gastroenteritis in both developing and industrialized countries. Knowledge of the diversity and antimicrobial susceptibility of the bacterium may be helpful in the management of both individual cases and outbreaks. This study was undertaken to evaluate the molecular epidemiology of an outbreak of diarrhea due to S. sonnei. The outbreak involved 14 of 28...

Antimicrobial drug resistance in treatment of urinary tract infection (UTI) continues to rise worldwide. To examine contributions of physician prescribing patterns to fluoroquinolone (ciprofloxacin, CP) resistance, we examined Escherichia coli (E. coli) resistance patterns in urinary cultures. Since CP usage is limited in children, we compared CP resistance trends in adults and children to thos...

Enterococci are found worldwide and are considered to be opportunistic pathogens. Antimicrobial resistance in these bacteria is increasing and is associated with their capability to sustain in the wastewater. We, therefore, aimed to determine the antimicrobial resistance of Enterococcus spp. that are isolated from the wastewater and clinical specimens. Isolation, identification, and de...

enterobacter asburiae ( e. asburiae) is a facultative anaerobic, non-spore-forming gram-negative rod-shaped bacterium belonging to the family of enterobacteriaceae . it is an opportunistic pathogen that its strains are isolated from a variety of clinical and environmental specimens. since powdered infant formula milk (pif) is not a sterile product, it is an excellent medium for bacterial growth...

Outbreaks of diarrhea in child day-care centers (DCC) are common. This study was undertaken to evaluate the molecular epidemiology of an outbreak of diarrhea due to Shigella sonnei. This outbreak involved 25 of 52 (48%) DCC children and 14 of 132 (11%) teachers and household contacts. S. sonnei isolates from nine children and five contacts were characterized by antimicrobial susceptibility, pla...

background: acinetobacter spp., as important opportunistic pathogens, have been found to be responsible for an increas­ing number of nosocomial infections. this study was undertaken to investigate the antimicrobial susceptibility and molecular typing of iranian isolates of a. baumannii . methods: the study was conducted over a period of 19 months in three hospitals in tehran, iran. acinetobacte...
