Species Infections Detected from Fecal Samples of Animal and Human Hosts in South Africa: Systematic Review and Meta-Analysis.

This study presents a systematic review and meta-analysis approach of species prevalence studies in animal and human hosts published between 1980 and 2020 in South Africa. Extensive searches were conducted on three electronic databases including PubMed, ScienceDirect and Google Scholar. The findings indicated an overall pooled prevalence estimate (PPE) of spp. infections in animals and humans at 21.5% and 18.1%, respectively. The PCR-RFLP appeared to be the most sensitive diagnostic method with a PPE of 77.8% for the detection of spp. infections followed by ELISA (66.7%); LAMP (45.4%); PCR (25.3%); qPCR (20.7%); microscopy (10.1%); IFAT (8.4%); and RDT (7.9%). In animal hosts, had the highest PPE of 3.7%, followed by (1.5%), (1.4%) and (1.0%), while in humans, also had the highest PPE of 18.3% followed by at 0.4%. The data generated in this study indicated that spp. infections were highly prevalent in both animals and humans in South Africa, especially in the KwaZulu-Natal and North West provinces. However, we further observed that there was a lack of prevalence studies for both animals and humans in some of the provinces. This study highlights the necessity for a "One Health" strategic approach promoting public hygiene, animal husbandry and regular screening for spp. infections in both animals and humans.
