The commonly used probiotics bacteria are lactic acid bacteria (LAB) from gastro intestinal tract. However, other LAB from exogenous origin having similar functional properties may also confer health benefit to the host. Palm wine has been described as a rich source of LAB. But very few studies have investigated their probiotic potential. Twenty LAB were isolated from palm wine collected in the South West Region of... Read more.

The yeast Candida is a normal flora of the skin and the mucous membrane and it then becomes pathogen in immunocompromised people. Various virulence factors are contributing to establishment of the infection in the host. Adherence of the pathogen to host tissues, yeast-hyphal transition and extracellular hydrolytic enzymes secretion are important virulence factors of Candida species. These hydrolytic enzymes play...

The purpose of this work was to evaluate the antimicrobial potential of endophytic fungi isolated from leaves and stems of Suaeda maritima and Suaeda monoica. Many endophytes were isolated by using potato dextrose agar (PDA) medium. All the endophytic isolates were identified by using standard taxonomic keys and monographs. From a total of 16 isolates, nine potent strains were taken for further study. The fungal culture... Read more.

The prevalence of antimicrobial resistant bacterial pathogens has become a major public health concern. Extended-spectrum ß-lactamase (ESBL) production in the members of the family Enterobacteriaceae can confer resistance to extended spectrum cephalosporins such as azetronam and penicillins. Integrons are genetic structures capable of capturing and excising gene cassettes, which usually encode... Read more.
