“…This is a common practice among backyard farmers in Nigeria. The free-range poultry farming system, as a result, poses considerable challenges in the management of ND, as it exposes the birds to direct contact with parasites and disease-causing pathogens in the environment [219,220]. This may also increase the chance of poultry's being exposed to wild birds, which will in turn increase the disease risk of the backyard poultry.…”

Introduction: Newcastle disease is a highly contagious illness and one of the "notifiable illnesses" on the World Health Organization list for Animal Health (OIE) Outcome. There are constantly new cases being reported as new NDV isolates from around the world. Newcastle disease poses a significant global economic threat to the poultry sector, causing highly contagious and transmissible diseases in birds with huge food security threat among the weak and vulnerable developing and underdeveloped countries Aim: The aim of this article borders on bringing to light the risk of possible Newcastle disease outbreak in Nigeria due to increasing poor management of poultry farms and poultry waste product. Furthermore, it will also underscore and outline various ways which can be adopted to prevent this poultry disease which is of great public health, economic and food security protection importance. Method/Methodology: This is a systematic review of published research articles focusing on Newcastle disease, epidemiology, pathogenicity, transmission and factors that can play important roles in the possible outbreak of the disease in poultries. Studies reviewed comprise of cross-sectional, prospective, longitudinal and observational studies. The study approach follows the systematic review of peer-reviewed published articles as well as online publications and articles derived from various databases with search keywords relevant to the topic of discourse. Findings and Results: The findings in this study highlight the endemicity of Newcastle virus disease in various part of the country, and how the severity of the disease is influenced by host characteristics, viral properties, and environmental factors. The study pointed out critical evidence-based possible reasons that could promote a new round of Newcastle disease epidemic outbreak as a result of poor poultry management practices such as high bird densities, poor poultry infrastructure, lack of quarantine of sick birds, mixed species rearing, free range system of poultry, poor waste disposal, lack of expertise, and insufficient biosecurity outcomes. However, the lack of education and awareness among farmers exacerbates the problem, hindering preventive measures. The complexity is increased by difficulties with vaccination, unrestrained bird movement through trading with neighboring countries and interstate, and a lack of diagnostic facilities. The consequences of an outbreak extends beyond financial losses to potential disruptions in the poultry supply chain, food security risks, and public health concerns. Conclusion and Recommendation: The growing difficulties in poultry management methods increases the serious public health concern posed by a possible Newcastle Virus epidemic outbreak in Nigeria. A paradigm shift in poultry farming practices is necessary to address this problem. A comprehensive strategy that incorporates infrastructural development, regulatory frameworks, and education in order to strengthen the poultry industry is needed, so as to address and prevent the looming public health and food security crises that may break out from the above scenario

“…The wild African harlequin quail (Coturnix delegorguei delegorguei ) is endemic to Eastern and Southern Africa and is commonly found in grassland areas with scattered bush cover (Lewis & Pomeroy, 1989). For generations, rural smallholder farmers in Kenya have hunted quail for consumption as a complementary source of poultry protein (Urban et al, 1986, Ogada et al, 2022. However, in addition to continuous and uncontrolled harvesting, breeding attempts by rural farmers, climate change, habitat destruction by humans, migration, population bottlenecks, and inbreeding are among the main challenges facing wild African harlequin quail in Kenya (Wamuyu et al, 2017;Ogada et al, 2021).…”

The wild African harlequin quails (Coturnix delegorguei delegorguei) of Western Kenya suffer from incessant hunting, habitat fragmentation, and the effects of climate change. These challenges, among others, have forced them to breed under intensive pressure, disrupting normal evolutionary processes. Here, we provide the first overview of the selection signatures in wild African harlequin quails using genotyping-by-sequencing information from 76 captured individuals. Additionally, 19 domestic Japanese quails (Coturnix coturnix japonica) were incorporated for comparative signatures of selection analysis between wild and domesticated quail species that undergo different selection pressures. Composite likelihood ratio test (CLR) and integrated haplotype score (iHS) methods were used to detect selection signatures. As a result, 252 and 424 candidate genes were detected in wild African harlequin and domestic Japanese quails, respectively, through the CLR test, whereas 150 and 457 candidate genes were identified through iHS. Some of the essential candidate genes identified in the wild African harlequin quail were associated with important traits such as immune response (MAPK13, MAPK14, CREB1, ITGB3, and PPP1CA) and morphological traits (WNT5A, GRIA1, CREB1, ADCY8, and ALK) whereas, in domestic Japanese quail, primarily production-related genes such as VIPR2, DYNLL2, COL6A3, MSX2, PRF1and GNA12 were identified. Our findings provide insights into the role of selection in shaping both wild and domestic quail genomes in terms of significant immune response, growth, reproduction, and morphological and behavioral traits.
