UNLABELLED Several broad-spectrum microbicides, including cellulose sulfate (CS), have passed conventional preclinical and phase I clinical safety evaluation and yet have failed to protect women from acquiring HIV-1 in phase II/III trials. Concerns have been raised that current preclinical algorithms are deficient in addressing the complexity of the microflora-regulated vaginal mucosal barrier....

the effects of dietary supplementation of grape seed extract (gse) and vitamin c on carcass characteristics, gut morphology and ileal microflora in broiler chickens exposed to chronic heat stress were examined. experimental diets included a control diet (without additive), 3 levels of gse (150, 300, 450 mg/kg of diet), and vitamin c (300 mg/kg of diet). each of the five diets was fed to 5 repli...

Antimicrobial agents are the most valuable means available for treating bacterial infections. However, the administration of therapeutic doses of antimicrobial agents to patients is a leading cause of disturbance of the normal gastrointestinal microflora. This disturbance results in diminishing the natural defense mechanisms provided by the colonic microbial ecosystem, making the host vulnerabl...

The human gut microbiota plays a significant role in human health through its ability to digest food ingredients and manufacture metabolites. This can be positive or negative for host welfare. Moreover, the microflora plays an active role in host defense whereby colonization resistance affords protection against pathogens. Prebiotics are nondigestible food ingredients that target beneficial com...

Background Increased prevalence of atopic disorders in children may be associated with changes in types of childhood infections, vaccination programmes, and intestinal microflora. People who follow an anthroposophic way of life use antibiotics restrictively, have few vaccinations, and their diet usually contains live lactobacilli, which may affect the intestinal microflora. We aimed to study th...

Autism of the regressive variety is selected as an example of the importance of intestinal bacterial microflora in disease other than classical infection. Our studies have indicated that intestinal bacteria play a role in this disease since it responds to oral vancomycin, a drug that is not absorbed from the GI tract. Pyrosequencing studies document an abnormal gut microflora in regressive auti...

ETHNOPHARMACOLOGICAL RELEVANCE Intestinal microflora plays crucial roles in modulating pharmacokinetic characteristics and pharmacological actions of active ingredients in traditional Chinese medicines (TCMs). However, the exact impact of altered intestinal microflora affecting the biotransformation of TCMs remains poorly understood. AIMS OF THE STUDY This study aimed to reveal the specific e...

Three hundred high vaginal swabs from pregnant women were cultured to investigate the vaginal flora during pregnancy. Two hundred swabs obtained from a private clinic were cultured aerobically for bacteria only, the remaining 100 from antenatal clinic of Khyber Hospital Peshawar were cultured both aerobically and anaerobically for bacteria and fungi (candida). Vaginal smears from patients in an...

Molecular methods have provided renewed impetus for the analysis of the composition of the intestinal microflora in health and disease. The polymerase chain reaction coupled with denaturing gradient gel electrophoresis provides a method whereby the bacterial communities in large numbers of samples can be compared efficiently and effectively. Altered bacterial populations associated with disease...

The majority of workers are agreed that the digestion of carbohydrate in the rumen is brought about by the micro-organisms living there, and furthermore, that the microflora plays a much larger part in these processes than the microfauna, for if the Protozoa are removed by drenching with dilute copper sulphate, the digestive processes continued unhampered (see Van der Wath, 1942). The precise r...
