There are many standards and recommendations for breathing air quality associated with respiratory protection equipment, but little has been done regarding the possible microbial contamination of medical air. The present study demonstrates quantitatively and qualitatively that pipelines might be incriminated as source of microbial contamination of compressed and synthetic air for medical use. A...

Anaerobic infections occur in surgical patients in part because of structural or functional defects in the host that (1) cause a breech in the normal mucosal barriers, (2) create localized vascular insufficiencies, or (3) produce an obstruction. Any or all of these events may compromise the oxidation-reduction potential within the tissues, encouraging rapid anaerobic growth. Although diverse an...

In a soil conditions like limestone mined spoils which has low soil nutrients level with poor nutrient cycling capacity; application of selected microbes as inoculants may be helpful in the establishment of plants in nutrient poor mined spoils. Pongamia pinnata grown on limestone mined over burden dump were supplemented with different microbial and inorganic fertilizer. Plants inoculated with m...

Persistence of microorganisms or reinfections are the main reasons for failure of root canal therapy. Very few studies to date have included culture-independent methods to assess the microbiota, including non-cultivable microorganisms. The aim of this study was to combine culture methods with culture-independent cloning methods to analyze the microbial flora of root-filled teeth with periradicu...

T cell responses to self Ags and normal microbial flora are carefully regulated to prevent autoreactivity. Because IL-10-deficient mice develop colitis, and this response is triggered by luminal flora, we investigated whether IL-10 regulates the ability of microbial Ags to induce autoreactive T cells that could contribute to intestinal inflammation. T cells from wild-type mice were primed with ...

OBJECTIVE To determine the conjunctival bacterial flora present in patients with Stevens-Johnson syndrome. METHODS A prospective study of the conjunctival bacterial flora was performed in 41 eyes of 22 patients with Stevens-Johnson syndrome. The information gathered included the patient's sex and age, the duration of disease, the cause of Stevens-Johnson syndrome, and treatments. Scrapings of...

The aerobic microbial flora of 823 eyes with acute bacterial conjunctivitis, corneal ulceration, dacryocystitis, discharging sockets, blepharitis, and postoperative infections has been investigated. Staphylococci, Streptococcus pneumoniae, and nonfermenting Gram-negative bacilli including Pseudomonas aeruginosa were the main pathogens. Fermenting coliforms were also infrequently isolated. The l...

MPP can be effective in the treatment of E. coli O101-induced diarrhea in mice. MPP can improve the weight loss caused by diarrhea, increase spleen and thymus indices, and reduce the diarrhea index. MPP can reduce the number of WBC, regulate the level of cytokines, and regulate the intestinal microbial flora. These data suggest that MPP is a promising candidate for treatment of E. coli-induced ...

Many patients receiving inpatient care or admitted as day cases undergo invasive procedures that place them at potential risk of healthcare-associated infection. Human skin is populated with microorganisms most of which are harmless, however some have pathogenic potential. This article outlines the protective function of intact skin and describes its resident and transient microbial flora. The ...

objectives : the present study was designed to evaluate the changes in saliva properties and oral microbial flora in patients undergoing fixed orthodontic treatment. materials and methods: two important saliva properties namely the salivary flow rate and ph as well as oral microbial flora were assessed in 30 orthodontic patients before starting fixed orthodontic treatment and after six, 12 and ...
