results among the 4,506 studied patients with urine cultures, 300 (6.65%) and 4,206 (93.35%) urine samples showed positive and negative bacterial growth, respectively. the rates of urine cultures with bacterial growth for women and men were 90.66% and 9.44%, respectively. with regard to the bacterial growth, 90.33% were gram-negative and 9.67% were gram-positive. the most common isolated agent ...

background: the science of identification and employment of medicinal plants dates ‎back to the early days of man on earth. cannabis (hashish) is the most common illegal ‎substance used in the united states and was subjected to extensive research as a ‎powerful local disinfecting agent for mouth cavity and skin and an anti-tubercular agent ‎in 1950.‎ methods: clinical strains were isolated from...

background mercury is one of the most toxic heavy metals. even a small amount of it is toxic for all living organisms. some of bacteria have developed special resistance mechanisms against mercury, in addition to resistant to different antibiotics. these bacteria usually acquire hg and antibiotic resistance genes via horizontal gene transfer in their habitat. objectives the aim of this study wa...

conclusions metronidazole and vancomycin still seem to be most effective drugs for treatment cdi. objectives the aim of this study was to investigate the antimicrobial susceptibility patterns of c. difficile clinical isolates against antibiotics commonly used for treatment cdi in hospitalized patients. material and methods during a 12 month study, 75 c. difficile isolates were collected from 39...

BACKGROUND Therapeutic antibiotic use in humans is a significant driver of antibiotic resistance. The seasonal effect of antibiotic use on antibiotic resistance has been poorly quantified because of lack of large-scale, spatially disaggregated time-series data on antibiotic use and resistance. METHODS We used time-series analysis (Box-Jenkins) on US antibiotic usage from IMS Health and on ant...

conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

OBJECTIVES Gastric carcinoma is the most common cancer and cause of cancer mortality in Peru. Helicobacter pylori, a bacterium that colonizes the human stomach, is a Group 1 carcinogen due to its causal relationship to gastric carcinoma. While eradication of H. pylori can help prevent gastric cancer, characterizing regional antibiotic resistance patterns is necessary to determine targeted treat...

The objectives were to determine the prevalence of group B streptococcus (GBS) and to characterize antibiotic resistance patterns. All pregnant women presenting to the triage units at two urban hospitals during three intervals from 2001 to 2004 were included. Each interval lasted approximately four weeks. Swabs were inoculated into selective broth and cultured on tryptic soy agar with 5% sheep ...
