The bacterial flora of marine animals collected at depths of 570 to 2,446 m was examined for population size and generic composition, and the barotolerant characteristics of selected bacterial isolates were determined. Total numbers of culturable, aerobic, heterotrophic bacteria were found to be low in animals collected at the greatest ocean depths sampled in this study. Vibrio spp. were predom...

The main goal of recent study was the impact assessment a commercially available fermented herbal feed supplement on digestion horses and intestinal microflora. experiment made with four adult horses. product consumed by animals for seven days in addition to usual oats hay diet, an amount 200g. Sampling before immediately after treatments 21 later. From fresh faecal samples number lactic acid c...

This study used a digesta transfer protocol to determine the site of absorption of lysine synthesized by the gastrointestinal microflora of pigs. Eight pigs were used, four with reentrant cannulas in the terminal ileum, two with simple T cannulas in the terminal ileum, and two intact. All pigs were given, for 5 days, the same low-protein diet that included fermentable carbohydrates. The diet of...

Lactobacillus and bifidobacterial cultures are increasingly used as probiotics in pharmaceuticals and in foods. The selection of strains is performed often for technological rather than for microecological reasons. Detailed reports about species and strains composition of these microorganisms in the intestinal microflora of man are rare. Our investigations were performed with samples originatin...

Antigenic cross-reaction has been demonstrated between homogenates of intestine taken from fetal mice and suspensions of a Bacteriodes species isolated from the large intestines of normal adult mice. This observation provides an explanation for the lack of immunological response observed in mice after antigenic stimulation with this member of the normal autochthonous intestinal flora of these a...

The development of genetically engineered animals has brought with it increasing concerns about biosafety issues. We therefore evaluated the risks of growth hormone from transgenic goats, including the probability of horizontal gene transfer and the impact on the microbial community of the goats' gastrointestinal tracts, feces and the surrounding soil. The results showed that neither the GH nor...

five strains of mouth normal microflora containing staphylococcus epidermidis, streptococcus mutant, lactobacillus acidophilus, actinomyces viscosos and candida albicans, were isolated and identified then cultured and purified on different media by using routine methods in microbiology. extract of 3 garlic samples south (khuzestan), north (mazanderan) and hamedan garlics, were affected on these...

The human intestine has evolved in the presence of diverse enteric microflora. TLRs convert the recognition of pathogen-associated molecules in the gut into signals for anti-microbial peptide expression, barrier fortification, and proliferation of epithelial cells. Healing of injured intestinal epithelium and clearance of intramucosal bacteria require the presence of intact TLR signaling. Nucle...

A double layer-coated colon-specific drug delivery system (DL-CDDS) was developed, which consisted of chitosan (CTN) based polymeric subcoating of the core tablet containing citric acid for microclimate acidification, followed by an enteric coating. The polymeric composition ratio of Eudragit E100 and ethyl cellulose and amount of subcoating were optimized using a two-level factorial design met...

Congenital candidiasis is a severe complication of candidal vulvovaginitis. It occurs in two forms,congenital mucocutaneous candidiasis and congenital systemic candidiasis. Also newborns are in age group the most vulnerable to invasive candidiasis. Congenital candidiasis should be considered as an interdisciplinary problem including maternal and fetal condition (including antibiotic therapy dur...
