Accurate measurement of bacterial and viral abundance in coastal marine environments is important to understand the dynamics of microbial communities in these ecosystems. In this study, the effect of formaldehyde preservation on the abundance of bacteria and viruses in water samples from Cochin Backwater was determined by SYBR Green I staining and epifluorescence microscopy. The counts were det...

Probiotic bacteria in plain yogurt namely of Lactobacillus ssp. have been reported to treat thrush, diarrhea, athlete’s foot, jock itch and vaginal yeast infections. Lactobacillus delbrueckii ssp. bulgarius (LB-12) and Streptococcus thermophilus (ST-M5) are lactic acid bacteria widely used in the manufacture of yogurt. Alcohol is used in manufacture of some medications such as cough syrups and ...

BACKGROUND Various causes of malabsorption syndrome (MAS) are associated with intestinal stasis that may cause small intestinal bacterial overgrowth (SIBO). Frequency, nature and antibiotic sensitivity of SIBO in patients with MAS are not well understood. METHODS Jejunal aspirates of 50 consecutive patients with MAS were cultured for bacteria and colony counts and antibiotic sensitivity were ...

Previous studies have reported that phagocytosed Bordetella pertussis survives in human neutrophils. This issue has been reexamined. Opsonized or unopsonized bacteria expressing green fluorescent protein (GFP) were incubated with adherent human neutrophils. Phagocytosis was quantified by fluorescence microscopy, and the viability of phagocytosed bacteria was determined by colony counts followin...

Bacteriological examinations were carried on four types of water samples which collected from tap water, river Nile ground and bottled at different cities in Dakahlia Damietta Governorates, Egypt during 2017/2018 order to determine the level total count bacterial isolates present our . These groups described as coliform bacteria, fecal streptococci, according counts methods. Generally,the highe...

A sewer main serving a large municipal wastewater system ruptured, discharging approximately 3,000,000 gallons (11,355,000 L) of raw human sewage into a multi-branched tidal creek estuary along the US East Coast. The biochemical oxygen demand caused severe hypoxia in the system, causing a large fish kill. The sewage load led to high fecal coliform bacteria concentrations in the creek (maximum o...

Counting bacteria in natural water samples by cultivation yields only low recovery efficiencies (ca. 1%), compared to total counts obtained after 4,6-diamidino-2-phenylindol (DAPI) staining. In order to optimize the cultivation of heterotrophic planktonic bacteria from Lake Constance (Germany), selected parameters of the medium composition were modified. The most important factor was the concen...

Abstract Background and objectives: Air ionization (AI) may reduce the microbial content of the air 'and has bactericidal effects on some bacterial Strains, which is controversial. We conducted this study to evaluate the efficacy of Air ionizer in reducing the microbial content of air. Material and Methods: This experimental Study was carried out in Sadi Hospital of Isfahan. Two air ionizer wer...

BACKGROUND As a cost-saving measure, an increasing number of hospitals allow personnel to launder their uniforms, lab coats, and operating room scrubs at home. With rising nosocomial infection rates and increasing levels of multidrug-resistant bacteria in hospital settings, uniform contamination may be an environmental factor in the spread of infection. METHODS We quantified the number and id...
