Foliar application of Azospirillum brasilense in soybean and seed physiological quality
Bacteria of the Azospirillum genus have considerable potential for application in agricultural systems, either in co-inoculation and foliar application to increase crop yields, due to its role in the production of phytohormones. The objective of this research was to evaluate the yield and quality of soybean seeds produced under the effect of different doses of Azospirillum brasilense bacteria applied to the leaves....

Antibacterial activity of extracts of three aromatic plants from Burkina Faso against rice pathogen, Xanthomanas oryzae
Plant extracts can have powerful antibacterial activity and may be used as biological control against important plant pathogens. This study assessed effect of extracts of Cymbopogon citratus, Eucalyptus camaldulensis and Mentha piperita against two pathovars of Xanthomonas oryzae attacking rice. Both in vitro and in vivo approaches were used for different strains of X. oryzae originating from Burkina Faso. The three...

Effect of tyrosol on Staphylococcus aureus antimicrobial susceptibility, biofilm formation and virulence factors
Staphylococcus aureus is considered the most common causative agent of community and hospital-acquired infections. The isolates with increased virulence and antimicrobial resistance, especially mecithillin resistant S. aureus (MRSA), represent a challenge in hospitals and health care facilities worldwide. The effect of tyrosol, a phenolic quorum sensing compound of Candida albicans, was studied on the sensitivity of...

Effect of non-steroidal anti-inflammatory drugs and dexamethazone on the biofilm formation and expression of some adhesion-related genes of Candida albicans and Staphylococcus aureus
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...

Effect of cholesterol lowering multiplex lactic acid bacteria on lipid metabolism in a hamster model
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...

Association study of single nucleotide polymorphism of human Toll like receptor 9 and susceptibility to pulmonary tuberculosis in Egyptian population
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...

Bacteriological and molecular studies on Clostridium perfringens isolated from sheep in three Egyptian provinces
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...
