Urinary tract comprises of kidney, ureter, urethra and genital organ and under normal circumstances these organs are sterile. Inflammation of these organ and parts may indicate the possibility of Urinary Tract Infection (UTI). It may be due to the colonization of wide range of bacteria either from normal microflora that is Escherichia coli or from other Gram negative or Gram positive bacteria. The present study was...

A unicellular cyanobacterium Synechococcus elongatus PCC 7942 was exposed to various concentrations of SeO42–. A growth supportive effect was seen at 50 µM concentration of SeO42− whereas 50% growth retardation was observed at 200 µM of SeO42−. Selenium (Se) stress at 200 µM SeO42− induced the formation of reactive oxygen species such as superoxide radical (O2•–),... Read more.

Groundnut is one of the staple foods in many parts of the world. Due to its high nutrient content, the nuts are liable to colonization by aflatoxigenic fungi and subsequent aflatoxin accumulation. This study was aimed at determining susceptibility of locally grown groundnut varieties to Aspergillus flavus in Homa Bay County, Western Kenya. A pretested questionnaire was used to survey agronomic practices on groundnut... Read more.

The objective of this study was to estimate the sero-prevalence of brucellosis in camels in Shalateen city, Red sea Governorate. A total of 801 Sera were collected from apparently healthy dromedary camels from 2014 to 2015 spring. Sera were consequently serologically tested and confirmed using Rose Bengal plate test (RBPT), buffer acidified plate antigen test (BAPAT) and complement fixation test (CFT). 103 (12.90%), 93...
