Candida albicans and Staphylococcus aureus can cause many diseases which are considered in many cases life threatening infections. Their biofilm formation on the surface of medical devices is difficult to be treated. Our study evaluates the effect of some anti-inflammatory drugs on the growth, biofilm formation and the expression of some adhesion-related genes. Antimicrobial activity of the tested drugs was determined... Read more.

This study aimed to investigate the effects of a probiotic complex product including Pediococcus, Lactobacillus, and Bifidobacteria on the lipid metabolism of hamsters fed a high-fat and high-cholesterol diet. Fifty male Syrian hamsters were assigned to five experimental groups: control, high-fat plus high-cholesterol diet (HFC), and HFC supplemented with low-, medium-, and high-dose of probiotic product. The hamsters... Read more.

Toll-like receptors (TLRs) are known to play important roles in human innate immune systems. Polymorphisms in and functions of TLRs have been investigated to identify associations with specific infectious diseases including tuberculosis (TB). This study was performed for 166 samples of unrelated individual's diagnosis of pulmonary tuberculosis and 98 household healthy samples. Genomic DNA was extracted from... Read more.

The study was intended to determine types of Clostridium perfringens and their toxins in diseased sheep with suspected enterotoxaemia, apparently healthy in contact sheep and soil in three Egyptian provinces (one year study). A total of 800 sheep were visited regularly over a period of one year to record cases of enterotoxaemia and collection of samples for bacteriological examination and toxin genotyping using...

Endophytic Methylobacterium spp. were inoculated on citrus seed and evaluated for their ability to promote growth of Citrus limonia and Citrus sunki seedlings under commercial nursery conditions. The germination rate and seedlings growth differed according to the combination between Methylobacterium species and citrus rootstock, showing that the interaction depends on their compatibility. Methylobacterium had no effect... Read more.

Campylobacter jejuni is one of the most important foodborne gastroenteric zoonosis. Most strains of C. jejuni produce a toxin (cytolethal distending toxin) that hinders the cells from dividing and produces diffuse bloody edematous exudative enteritis. The common routes of transmission are fecal-oral, person-to-person and the eating of raw or undercooked chickens or meat. This study recognizes the incidence of zoonotic... Read more.
