“…In a 3 year prospective study conducted in southeastern Nigeria involving a clinical and laboratory-based test, ND outbreaks were observed to peak during the dry harmattan period (November to February) with another marginal peak recorded during the height of the rainy season (June to July) [77]. In other reports, high prevalence of ND outbreaks was also observed mostly in the dry harmattan period [57,64,69,73,77,90,110] in which stress and cold associated with the weather are said to be responsible for this occurrence [64,77]. In addition, movements of birds across different parts of the country are witnessed around this time in preparation for the festive period (Christmas and Easter).…”

Newcastle disease in Nigeria: epizootiology and current knowledge of circulating genotypes

Over the years, Newcastle disease (ND) has defied all available control measures. The disease has remained at the forefront of infectious diseases afflicting poultry production after avian influenza. Despite the continuous global use of million doses of ND vaccine annually, the causative pathogen, avian paramyxovirus type 1 also known as Newcastle disease virus (NDV) has continued to evolve causing, even more, a threat not only to the unvaccinated but the vaccinated flocks inclusive. The disease has been well studied in the developed countries where the virus is found in circulation. However, limited information exists on the epizootiology and circulating genotypes of the virus in developing countries where the majority of the flocks are raised on the extensive management system. Identification of virulent NDV in apparently healthy free-range ducks in this system calls for concern and pragmatic approach to investigate factor(s) that favour the virus inhabiting the ducks without clinical manifestation of the disease. Recently, novel genotypes (XIV, XVII, and XVIII) with peculiarity to West and Central African countries have been discovered and due to lack or poor surveillance system possibility of hitherto unreported genotypes are likely. This review elucidates and discusses available literature on the diversity of the circulating NDV genotypes across the West Africa countries and the epizootiology (molecular) of the disease in Nigeria with the view of identifying gaps in knowledge that can assist in the development of effective vaccines and control strategies to combat the peril of the disease.

“…In each LGA, four villages were selected, and from each village four (4) households that owns moderate number of village chickens and that were willing to volunteer, cooperate and give full support for the success of the study were randomly selected. The Local Government Areas that were used for this study were Gombe, Akko, Kwami, Funakaye and Yamaltu Deba Local Government Areas.…”

“…Newcastle disease (ND) is an acute, contagious and highly pathogenic viral disease of both domestic and wild birds worldwide [1][2][3][4]. This disease is caused by a diverse group of viruses with the highly virulent strains endemic in Nigeria [5,6].…”

“…The protection afforded by an efficacious vaccine not only removes the need for the administration of treatments, but also guards against the economically damaging consequences of disease [15,18]. Avirulent NDV 4 and ND I 2 strains of ND vaccines have been reported to give varying degrees of successes in both laboratory and field trials [19][20][21][22]. This study is therefore aimed at studying the responses of village chickens to Newcastle disease I 2 vaccine coated on maize grit as vaccine vehicle.…”

A study of response of village chickens to vaccination with ND I 2 vaccine coated on maize grit as vaccine carrier was carried out in some selected LGAs of Gombe State, using haemagglutination inhibition (HI) test. Vaccination efficacy of maize grit coated with Newcastles Disease I 2 vaccine has been compared between adult and young, village chickens. The study showed that 94.3% of the vaccinated village chickens (adults and chicks) seroconverted with protective levels of antibodies against ND virus. Those vaccinated with the maize grit coated vaccine exhibited antibody titres of between 1:16 to 1:8192 with GMT values of 109 to 245. There was a significant difference (P<0.05) in the response of the vaccinated adult village chickens as compared to the younger birds (chicks). It is concluded from the study that maize grit is a very suitable vaccine carrier for the delivery of ND I 2 vaccine to village chickens.

“…Although NDV can be destroyed by heat, ultraviolet rays of the sun, and some disinfectants, it can survive for several weeks in a warm and humid environment, on birds' feathers, manure, and other materials, and in frozen materials [1]. In Nigeria and other developing countries, poultry is one of the major sources of animal protein to man, and it provides quick returns on investment compared to livestock, and this led to increased attention to poultry health by farmers [5,6]. Studies carried out in rural chickens in Nigeria by Ezeokoli et al [7] showed 73% prevalence of antibodies to NDV in traditionally managed backyard flocks in Zaria; 63% seroprevalence was reported by Orajaka et al [8] in southeastern Nigeria; 38% seroprevalence was reported by Oyewola et al [9] in southwestern Nigeria around Ibadan; and Musa et al [10] reported prevalence of 51.9% in Plateau State.…”

A serological survey was carried out in four area councils (Abuja Municipal, Kuje, Gwagwalada, and Kwali) of the Federal Capital Territory (Abuja) to determine the prevalence of antibodies to Newcastle disease virus in local chickens using haemagglutination inhibition (HI) tests. In each area council, one hundred sera samples were collected from apparently healthy local chickens with no history of vaccination. Abuja Municipal, Kuje, Gwagwalada, and Kwali area councils had prevalence of 37, 44, 79, and 68%, respectively. The overall prevalence of antibody to Newcastle disease in the four area councils was 57%. This study shows that Newcastle disease virus is circulating in local chickens in the study area, and this may pose a serious threat to the commercial poultry industry within these four area councils of the Federal Capital Territory (Abuja) where this study was carried out.
