background and objectives: the emergence of extended-spectrum β-lactamase (esbl)-producing shigella spp.  is of increasing clinical concern specially in children worldwide. the aim of this study was to investigate the occurrence of extended-spectrum β-lactamase producing shigella spp. in tehran, iran. materials and methods: the study included all shigella isolates recovered from pediatric patie...

conclusions periodic evaluation of antimicrobial susceptibility for c. perfringens should be performed. harboring of enterotoxigenic c. perfringens in individuals not necessarily results in diarrhea. results of 136 stool samples including diarrhea [48] and non-diarrhea [88] ones, 83 (61.02%) c. perfringens were cultured. of these 83, 79 c. perfringens isolates showed the alpha-toxin (phospholip...

conclusions: ten percent of the isolates were positive for meca gene among the vancomycin-oxacillin resistant strains, while van gene was not detected in any of the isolates. the data obtained would be useful in clinical control of resistant staphylococcal strains. results: a total of 120 staphylococcus isolates were screened, out of which, 32 (26%) were susceptible to both methicillin and vanc...

Antibiotic use is the main driver in the emergence of antibiotic resistance. Another unexplored possibility is that resistance evolves coincidentally in response to other selective pressures. We show that selection in the absence of antibiotics can coselect for decreased susceptibility to several antibiotics. Thus, genetic adaptation of bacteria to natural environments may drive resistance evol...

To promote heightened vigilance concerning antibiotic agents in Canadian hospitals, Accreditation Canada has implemented antibiotic stewardship as a required organizational practice.1 Antibiotic stewardship is the process of ensuring that only necessary and appropriate antibiotic agents are used and that their use is appropriate for each individual patient. It involves optimizing all steps of a...

objective(s) amongst the various antibiotic resistant elements in vibrio. cholerae, sxt constin (sxt-c) is important. we were going to design a quick method for determination of antibiotic resistance gene pattern in sxt-c. materials and methods ninety four v. cholerae o1el tor isolates were used in this study. antibiotic susceptibility testing, multiplex pcr amplification of sxt-c containing df...

abstract background: acute respiratory infections (ari) are the main cause for antibiotic (ab) use in all age groups specially the first two years of life. the local information about the pattern of ab prescription in ari is a necessary part for any program which aims logical use of ab. the current study was designed to find the frequency and types of ab administration for ari in young children...

one of the great challenges in the treatment of infectious diseases is the resistance of pathogenic bacteria against antibiotics, and antibiotic resistance to shigella is broadly observed in different parts of the world. the object of this study was to determine shigella antibiotic resistance pattern against the antibiotics such as ampicillin, amoxicillin, trimethoprim-sulfamethoxazole, chloram...
