The epithelial surfaces of the upper respiratory tract are continuously exposed to a wide variety of commensal microorganisms. In addition to acting as a physical barrier, epithelial cells respond to specific microbial products with the generation of signals, such as cytokines, that trigger inflammation. Because they are common components of the nasopharyngeal flora that share the potential to ...

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...

In the Middle East, dust and sand storms are a persistent problem delivering significant amounts of particulates via inhalation into the mouth, nasal pharynx, and lungs. The health risks of this dust inhalation are not well studied nor effectively characterized. Experiments were designed to study the chemical composition, mineral content, or microbial flora of Kuwaiti and Iraqi dust for its pot...

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...

conclusions the presence of fungi in the nasal cavity and indoors of healthy subjects in this study suggests that fungi should be considered as health hazards. furthermore, it is important and seems necessary to monitor indoor air quality and raise awareness of existing threats due to microorganisms, including fungi. results the most common fungi isolated from all samples were aspergillus, peni...

Mechanisms underlying the conditioning influence of the intestinal flora on mucosal homeostasis, including development and function of immune responses, are attracting increasing scientific scrutiny. The intestinal flora is a positive asset to host defense, but some of its components may, in genetically susceptible hosts, become a risk factor for development of inflammatory bowel disease (IBD)....
