The microbiological quality of water from a wastewater treatment plant that uses sodium hypochlorite as a disinfectant was assessed. Mesophilic aerobic bacteria were not removed efficiently. This fact allowed for the isolation of several bacterial strains from the effluents. Molecular identification indicated that the strains were related to Aeromonas hydrophila, Escherichia coli (three strains...

CONTEXT In the developing world, drinking water is an important route for transmission of diarrheal disease, a leading cause of morbidity and mortality in children. OBJECTIVES In Field Trial 1 (FT1) and Field Trial 2 (FT2), the effectiveness of the behavior change approach known as motivational interviewing (MI) was compared to the standard practice of health education alone in initiating and...

Chytridiomycosis, a disease contributing to amphibian declines worldwide, is caused by the fungus Batrachochytrium dendrobatidis. Identifying efficient and practical disinfectants effective against B. dendrobatidis is important to reduce the spread of the disease both in the wild and captivity. Previous studies identified a range of suitable disinfectant strategies. We evaluated the suitability...

formalin is a common disinfectant and therapeutic agent in fisheries-related activities. considering large variation in susceptibility of different species to formalin toxicity, it is necessary to determine its toxicity and safety margins in different species, separately. therefore, to investigate formalin acute toxicity and safety margins on caspian roach, an experiment was conducted in 1g cas...

Background and purpose: Staphylococcus sp. are pathogenic bacteria widely investigated for its high incidence in clinical environments ability to form strong biofilms. The biofilm-related infections can resist several antimicrobial agents; therefore, the therapy of these may face difficulties. aim this study is identify staphylococcal isolated from dental clinics, evaluate effect some disinfect...

Most infants admitted to premature baby or neonatal surgical units are nursed in incubators during part of their stay in hospital. There are many advantages of nursing these infants in incubators, but there is also one great disadvantage, the danger of bacterial colonization and contamination inside the incubator. The temperature inside the incubator approaches that of the body and many of thes...
