results in general 438 urine isolates were obtained. e. coli was the most frequently occurring pathogen (54.80%), followed by klebsiella pneumoniae (16.0%), coagulase negative staphylococci (11.2%), enterobacter spp. (9.6%), proteus spp. 1.4% and p. aeruginosa (1.4%). resistance rates of e. coli isolates were 85.9% to co-trimoxazole, 80.0% to penicillin, 77.0% to ampicillin, 68.0% to chloramphe...

Antimicrobials Organism Uropathogen Susceptibility patterns Urinary tract infections (UTI)

background and objectives: urinary tract infections (utis) are of the most common bacterial diseases worldwide. we investigate the antibiotic susceptibility patterns of escherichia coli (e. coli) strains isolated from pediatric patients with community acquired urinary tract infection (uti) to find a clinical guidance for choosing a right empirical antibiotic in these patients. materials and met...

BACKGROUND AND OBJECTIVE The relative contribution of nitric oxide (NO) to the killing of Mycobacterium tuberculosis in human tuberculosis (TB) is controversial, although this has been firmly established in rodents. Studies have demonstrated that clinical strains of M. tuberculosis differ in susceptibility to NO, but how this correlates to drug susceptibility and clinical outcome is not known. ...

The serotype, Shiga toxin (Stx) type, and antimicrobial resistance patterns of 138 Stx-producing Escherichia coli (STEC) strains isolated from humans between 2003 and 2007 in Shizuoka Prefecture, Japan were characterized. The predominant O serogroups of the STEC isolates were O157, O26, and O111. Antimicrobial susceptibility testing of the STEC isolates showed that 31 of the 138 isolates (2...

BACKGROUND: Salmonellosis is one of the most importantzoonotic diseases throughout the world. OBJECTIVES: Thepurpose of this study was to characterize a large collection ofSalmonella isolates from different poultry sources in Iran.METHODS: A total of 123 Salmonella isolates from differentpoultry sources were subjected to drug susceptibility test,hemolysin production, motility test, and plasmid ...

Background: Pediatric patients on chemotherapy are vulnerable to invasive fungal infection especially Candida spices. Resistance to antifungal agents has increased in Candida spp., especially in non-albicans species. This study aims to assess the susceptibility of Candida spp. strains isolated from children with acute leukemia less than 18 years. Materials and Methods: This prospective cross-s...

Current life cycle impact assessment (LCIA) practices use a characterization factor to linearly scale chemical emission human health assuming homogeneous exposure and toxicological susceptibility for the entire population. However, both may vary within population, making same elicit disproportionate impacts. Here we explore how inter-individual variabilities in interact affect estimated overall...
