Salmonella Heidelberg reduces nitrergic neurons in the myenteric plexus of the duodenum of broilers

The present study aimed to characterize the effects of Salmonella Heidelberg challenge, as well as its changes in the inhibitory neuron subpopulation in the myenteric plexus of broilers. At the age of 21 days, after euthanasia of birds, duodenum fragments were collected from 5 male chicken broilers Cobb 500 linage from the challenged group and the control group for the quantification from the subpopulation of myenteric...

Antioxidant modulation in response to selenium induced oxidative stress in unicellular cyanobacterium Synechococcus elongatus PCC 7942

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•–),...

Susceptibility of locally cultivated groundnut (Arachis hypogaea) varieties to aflatoxin accumulation in Homa Bay County, Kenya

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...
