    Genetic variations in two edible frog species (Crowned Bullfrog (Hoplobatrachus occipitalis) and African clawed frog (Xenopus muelleri)) in Ibadan, Nigeria using Allozyme markers
    (University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, 2021) Coker, O. M.; Osaiyuwu, O. H.; Oko, P. A.; Awosan, G. P.; Fijabi, O. E.
    Attempts to determine interspecific differences in patterns of protein variation in edible frog species have been relatively few. Therefore, this study determined the genetic variation in populations of Hoplobatrachus occipitalis and Xenopus muelleri in two locations [University of Ibadan (UI) and Igbo Oloyin area (IO)] in Ibadan, Nigeria, using five allozyme loci. Eighty (80) edible frogs comprising twenty (20) live samples each of H. occipitalis and X. muelleri species from IO and UI were collected. 1ml of blood was drawn per sample via cardiac venipuncture. Plasma fractions were obtained and subjected to Cellulose Acetate Electrophoresis to determine the genetic variations at Haemoglobin (HB), Carbonic anhydrase (CA), Transferrin (TF), Albumin (AL) and Esterase (EST) loci. Test for Hardy–Weinberg Equilibrium (HWE; ), Heterozygosity [observed (Ho) and expected (He)] and Genetic differentiation (FST) were estimated. Significant deviations from HWE were observed at several loci in all the populations. Ho was higher (than He) for both populations of H. occipitalis but lower for both populations of X. muelleri. FST was 0.0559 and 0.0264 for the populations of H. occipitalis and X. muelleri, respectively. There is an indication of evolutionary forces in operation in the IO populations of H. occipitalis and X. muelleri.

    Genetics of wildlife diseases and its impact on biodiversity conservation
    (2018) Coker, O. M.
    Diseases of wildlife origin have great impact on the conservation of the vast global biodiversity and also take a toll on domestic animals’ and human health. Diseases of wildlife have the capacity to be of utmost concern because they can affect the economy and public health if not attended to promptly. An amazing 60% of emerging infectious diseases are zoonotic and many of the recent cases have been proved to originate from wildlife. Knowledge of genetics is important to curtail the emergence of overwhelming wildlife diseases. Understanding the genetics of these diseases is important to give a better understanding of how they can be prevented and controlled to forestall the decimation of wildlife populations and consequent effect on biodiversity. Being armed with the knowledge of both, host and pathogen or parasite genome, would go a long way to pursue the solutions to wildlife diseases and their transmission. This review is geared towards promoting the incorporation of genetics and genomics and its diverse concepts and techniques into the process of detection, characterization, control and prevention of wildlife diseases.
