“…The sero‐positivity of young piglets born on a farm indicated the presence of virus in the farm but this study limits the samples from young piglets. A screening study of PRRSV (PRRSV 1 and PRRSV 2) antibodies in Nigeria showed the prevalence of 53.8%, which is higher than the findings of our study (Aiki‐Raji et al., 2018 ). Likewise, in Great Britain, the herd prevalence of PRRSV was reported to be 39.8% in 2004 (Evans et al., 2008 ).…”

Background Porcine reproductive and respiratory syndrome is a highly infectious disease of swine caused by PRRS virus (PRRSV). Objectives To evaluate the prevalence of PRRSV antibodies in the four districts of hilly and terai regions of Nepal. Toassess the farm characteristics through a questionnaire interview of farmersregarding management practices and PRRS. Methods A cross‐sectional study was conducted from July 2020 to June 2021 to determine the sero‐prevalence of PRRSV in pigs. A total of 180 porcine serum samples were collected from 23 pig farms and tested for PRRSV antibodies by ELISA. Alongside, farm characteristics were also assessed through questionnaire to determine the level of biosecurity measures in the farm, knowledge of the disease and possible control mechanisms. Results Out of 180 samples, 37 were tested positive resulting the overall sero‐prevalence of 20.5%. There was significant association between different districts ( p < 0.05) and PRRS prevalence. Prevalence of PRRSV antibody was found higher in Kaski district (10.5%) followed by Sunsari (8.8%) district. Based on age groups, highest prevalence was found in age groups of above 18 months (9.4%), followed by 13–18 months age groups (7.7%). Regarding the knowledge level of the disease, 43% of the farmers responded that they have heard about the disease. Biosecurity practices in the farm was found very poor where only 40% of the farms had disinfectant at the entrance of the farm and 25% pig farmers were found using separate boots while dealing with pigs. Conclusions The findings of this study reveal the presence of PRRSV antibodies in pigs of Nepal. In addition poor biosecurity measures, management practices and poor knowledge level about the disease among farmers highly affect in the control and prevention of disease thereby affecting the pig production and productivity. Therefore, government should develop and implement effective control measures and biosecurity programs.

“…The overall prevalence of anti-PCV2 antibodies in the pig sera was 1.4 % (5/364), with more female pigs (4/237, worldwide [8]. In the present study which is part of ongoing surveillance for porcine viruses of economic importance in Nigeria [2,3,4], the detection of PCV2 IgG antibodies in asymptomatic pigs slaughtered at a major abattoir in southwest Nigeria indicates natural infection with the virus since vaccination against the disease is not practised in the country. It was observed in this study that there was no meat inspection in the pig slaughterhouse probably due to lack or inadequate veterinary personnel.…”

A Slaughterhouse Survey for Porcine Circovirus Type 2 in Commercial Pigs in Ibadan, Southwest Nigeria

Porcine circovirus type 2 (PCV2) is recognized as one of the most important agents of reproductive disorders in gilts and sows worldwide. It is associated with considerable economic losses in the swine industry due to the unthriftiness, and variable morbidity and mortality it causes in pigs. In spite of the devastation caused by this virus to the global pig industry, there is little or no report of its occurrence in Nigeria. Hence, a slaughterhouse based survey was conducted to determine the prevalence of PCV2 infections in pigs in Ibadan, southwest Nigeria. Using a commercial ELISA kit, 364 pig sera collected from a major abattoir were screened for IgG antibodies against PCV2. The overall prevalence of anti-PCV2 antibodies in the pigs was 1.4 % (5/364), with more female pigs (4/237, 1.7 %) being seropositive than males (1/127, 0.8 %). Since there is no routine vaccination against this swine disease in Nigeria, thus the antibodies detected in the pig sera indicated a natural exposure to the virus. The absence of clinical disease in the pigs also suggests the possibility of a carrier status for these animals and shows that they could serve as hosts for the perpetuation of the disease. These findings underscore the need for continuous surveillance for PCV2 among pigs in Nigeria in order to determine its contribution to production losses incurred in the Nigerian swine industry and aid the development of prevention and control strategies against the disease.

“…In Nigeria, according to Aiki-Raji et al (2018), the status of PPV1 in Nigerian pigs is largely unknown. In their sero-prevalence study recently done to unravel the prevalence of PRRSV and PPV1 in pigs from the southwestern region of the country, a prevalence of 36.1% was obtained for the classical porcine parvovirus in the studied area which comprised only two states, Oyo and Lagos (Aiki-Raji et al, 2018). This finding also calls for proactive surveillance of the pathogen in pigs from the country in order to determine its true status in swine herds of the country so as to facilitate effective control measures.…”

A B S T R A C TDetection of infectious viral agents has been on the increase globally with the advent and usage of more sensitive and selective novel molecular techniques in the epidemiological study of viral diseases of economic importance to the swine industry. The observation is not different for the pig-infecting member of the subfamily Parvovirinae in the family Parvoviridae as the application of novel molecular methods like metagenomics has brought about the detection of many other novel members of the group. Surprisingly, the list keeps increasing day by day with some of them possessing zoonotic potentials. In the last one decade, not less than ten novel swine-infecting viruses have been added to the subfamily, and ceaseless efforts have been in top gear to determine the occurrence and prevalence of the old and new swine parvoviruses in herds of pig-producing countries worldwide. The story, however, is on the contrary on the African continent as there is presently a dearth of information on surveillance initiatives of the viruses among swine herds of pig-producing countries in the region. Timely detection and characterization of the viral pathogens is highly imperative for the implementation of effective control and prevention of its spread. This review therefore presents a concise overview on the epidemiology of novel porcine parvoviruses globally and also provides up-to-date highlights on the reported cases of the viral agents in the African sub-region.
