(Frontiers Media, 2020-05-05)Ticks and tick borne diseases (TBDs) undermine livestock production with considerable economic losses to livestock producers in endemic areas worldwide. Despite the impact of ticks and TBDs in livestock production, there ... -
Significance of antiviral therapy and CTL-mediated immune response in containing hepatitis B and C virus infection.
(Elsevier B. V., 2021-01-12)Viral infections remain a major cause of deaths globally. Here, we focus on Hepatitis B and C viruses (HBV and HCV) infection dynamics in the liver and blood cells, taking into account non-cytotoxic and cytotoxic mediated ... -
Single nucleotide polymorphisms in ghrelin gene and the resulting genetic variants at ghrelin locus in different strains of indigenous Tswana chickens
(Academic Journals, 2012-05-12)Ghrelin is a growth hormone releasing peptide which also affects feed intake in chickens. Ghrelin is encoded by chicken ghrelin gene (cGHRL) found in chromosome 7. Single nucleotide polymorphisms (SNPs) have been reported ... -
