according to changes in the surface of respiratory epithelial cells and host immunity as well as virulence of hospital acquired pathogens, oropharyngeal colonization enhance in hospital admitted patients. patient admission in hospital, due to changes of oropharyngeal flora and colonization of virulent germs such as staphylococcus aureus and gram negative bacilli can be a serious problem for dev...

The microbial flora associated with fleas may affect their ability to transmit specific pathogens, including Yersinia pestis, and also could be used to develop paratransgenesis-based approaches to interfere with transmission. To begin addressing this hypothesis, the microbial flora associated with the relatively efficient Y. pestis vectors Xenopsylla cheopis (Rothschild) (Siphonaptera: Pulicida...

this study was conducted to evaluate the effects of beta plus probiotic, a mixture of bacillius leicheniformic and bacillius subtilis , on the growth performance and intestinal microbial flora of caspian trout ( salmo caspius ). a basal diet was formulated and supplemented with beta plus at 0, 0.5 and 1 g kg -1 , leading to three experimental diets. each experimental diet was randomly assigned ...

In a healthy human, the internal tissues, e.g. blood, brain, muscle, etc., are normally free of microorganisms. However, the surface tissues, i.e., skin and mucous membranes, are constantly in contact with environmental organisms and become readily colonized by various microbial species. The mixture of organisms regularly found at any anatomical site is referred to as the normal flora. The norm...

OBJECTIVES To determine whether intravaginal clindamycin cream reduces the incidence of abnormal pregnancy outcome in women with abnormal vaginal microbial flora graded as intermediate or BV and to investigate the effect of the antibiotic on vaginal microbial flora. METHODS A prospective cohort study of pregnant women in an antenatal clinic of a district general hospital. The subjects were 26...

The oral cavity being the hub of gamut of microbes, promotes the establishment of distinct microbial communities, such as on the mucosa and teeth. Metabolism of these organisms facilitates the attachment and growth of the subsequent colonisers. A delicate balance is maintained in the microbial ecosystem, with these organisms contributing to normal development and defences. However, any change o...

Microbial flora of the skin of three human population groups representing different natural environments was examined quantitatively and qualitatively to determine whether environmental differences in temperature and humidity can influence the microbial flora of normal skin. Five anatomical skin sites - hands, back, axillae, groin, and feet - were sampled from 10 subjects working in a high-humi...

Probiotic supplements transform the intestinal microbial flora and enhancing gut and immune function. The intestinal microbial flora the gastrointestinal tract. These bacteria are integral to the protection of the body from infection, and maintenance of intestinal homeostasis. The microbial flora with intestinal epithelial cells and immune tract, skin and uro-genital tract. The exercise highlig...
