Introduction: Large quantities of antimicrobials are used in hospitals for patient care and disinfection. Antibiotics are partially metabolized and residual quantities reach hospital wastewater, exposing bacteria to a wide range of biocides that could act as selective pressure for the development of resistance. Methodology: A cross-sectional study was conducted between December 2010 and Februar...
Various kinds of pathogenic bacteria derived from the intestinal tract of animals exist in compost material like cow dung. In order to sterilize the pathogenic bacteria completely in compost material, the cow dung was put into a heat treatment machine in pilot plan, and harmless condition in short time was examined. The results indicated, pathogenic indicator bacteria such as coliform bacteria,...
Interoduction: Gasteroenteritis is one of the problems worth consideration all over the world. It is one of the important causes of mortality, especially in children < 5 years of age, in developing countries including Iran. The aim of this descriptive study was to determine the demographic conditions influencing the presence of causative bacteria and protozoa, followed by antibiograms of isolat...
Grand Bay National Estuarine Research Reserve (NERR) is an important ecosystem in the Mississippi Gulf Coast. It serves as important nursery areas for juveniles of many species of fish. The bay is also used for fishing, crabbing, oyster togging, boating as well as recreation. Like in other aquatic environments, this bay may be contaminated by microorganisms including pathogenic bacteria. The ob...
Background and purpose: Sexually transmitted diseases (STD) are very common throughout the world. In this study the prevalence of vaginitis caused by Trichomonas vaginalis, Candida albicans and pathogenic bacteria was investigated in women referring for Pap smear to Imam Khomeini and Boalicina hospitals in Sari, 2008-9. Materials and methods: In this descriptive retrospective study, a total of...
Gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. Gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. This study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. Enriched and specific media used for isolation of bacteria. Identification of isola...
Background and Aim: Lactobacillus is the most important genus of lactic acid bacteria and the use of some species of lactobacillus with the probiotic potential can be effective for inhibition of the growth of some pathogens and control of gastrointestinal diseases and cancers. In this study, the pro-apoptotic and antimicrobial effect of Lactobacillus sakei on human colorectal adenocarcinoma c...
The study of microbial pathogenesis has been primarily a reductionist science since Koch's principles. Reductionist approaches are essential to identify the causal agents of infectious disease, their molecular mechanisms of action, and potential drug targets, and much of medicine's success in the treatment of infectious disease stems from that approach. But many bacteria-caused diseases cannot ...
