introduction: bacterial translocation is defined as the passage of bacteria from intestinal tract to the extraintestinal organs such as the peritoneum and blood circulation. the aim of this study is to examine bacterial translocation (regarding type of bacteria and effect of time of obstruction on bacterial translocation) from intestinal lumen to the peritoneum and viscera in acute, simple mech...

conclusions mobiles contamination with different pathogens is extremely common among our health care staffs compared with other societies, and resistance of these isolates to various antibiotics is also detectable. thus, quick assessment of this issue to prevent the spread of these infectious agents is critical for the authorities in our health care systems. results in total, 99.2% of mobile ph...

background: sub-acute bacterial endocarditis (sbe) rarely presents with features of a small vessel vasculitis. patients with sbe can also develop multiple serological abnormalities including anca. in this report, we present a case of infective endocarditis mimicked anca associated glomerulonephritis.case presentation: a 57-year old male with a clinical picture of rapidly progressive renal failu...

discussion: the present case demonstrates that the uropathogenic e. hermanii clone can cause destruction of the kidneys. during asymptomatic bacteriuria or cystitis, the bacteria remain in the urinary tract. even when pyelonephritis develops, inflammatory response of the host is still restricted to the urinary tract. these signs mean that uropathogenic e. hermanii may be not very virulent. intr...

antibiotic guidelines have proven to be a simple and effective intervention to guide the choice of appropriate empiric antibiotic regimens. the goals of this study were to evaluate adherence to guidelines and streamlining of antibiotics. hospital records of hospitalized patients in infectious diseases ward imam khomeini hospital, tehran, iran, from may 2008 to september 2009 were reviewed. adhe...

background: infections are readily transmitted as a result of bacterial contamination of swimming pools. therefore, hygiene and preventing the contamination of swimming pools is of particular importance. the objective of this study was to determine the amount of bacterial contamination in indoor pools of yazd in 2013. methods: in this descriptive and analytical study, all indoor swimming pools ...

background:  aeromonas spp. can cause diarrhea and various infections in humans. access to rapid techniques with a high sensitivity and specificity is strongly needed for the identification of aeromonas species. the aim of this study was to evaluate two different methods including api 20e bacterial identification tests and the molecular detection using pcr primers specific for 16s-rrna and 23s-...

bacterial leaf streak (bls) caused by xanthomonas translucens pv. cerealis (xtc) is an important disease of wheat (triticum aestivum l.) worldwide. the management methods presently in practice are insufficient to meet current safety and/or efficacy standards. therefore, use of resistant genotypes is the best approach to manage bls. the present study was undertaken to identify possible sources o...

background: streptococcus pneumoniae (s. pneumoniae) is a gram-positive pathogen bacteria which causes a variety of diseases, including otitis media, bacteremia, and meningitis. cases report : a 19-year-old man with paroxysm was admitted to emergency department of hospital. he was diagnosed with s. pneumoniae meningitis on the basis of an analysis of the cerebrospinal fluid and blood culture. c...

ba ckground: legionella pneumophila is  a  dangerous pathogenic bacterium can cause serious infectious diseases especially in hospitalized immuno-compromised patients. this bacterium is shown to be resistant against different antibiotics. resistance against a wide range of antibiotics is usually mediated by efflux pump in bacteria. efflux pumps are proteinaceous transporters localized in the cy...
