“…The prevalence of brucellosis from vaginal swabs obtained from different animals was 12.4%, while a prevalence of 29.4% was observed in the lymph node of cattle from NW Nigeria. Thus far, only 7 out of the 104 publications reported culture detection methods [ 15 , 21 , 33 , 36 , 42 , 95 , 97 ], while a single publication reported molecular methods [ 78 ]. The Rose Bengal rapid test is the most popular diagnostic method reported by 11/14 publications on the detection of human brucellosis, while 95/107 publications reported RBPT as the detection method in animal samples.…”

The global burden of human and animal brucellosis remains enormous. The disease, which is endemic in Nigeria, lacks appropriate attention and national data. This review estimated the burden and distribution of human and animal brucellosis in Nigeria in the last twenty years (2001–2021). Publications reporting the detection of brucellosis in Nigeria were sorted from different search engines, including PubMed, ResearchGate, Scopus, and Google Scholar, to generate data on its prevalence, spatial distribution, and predisposing factors. The results of the national seroprevalence of human and animal brucellosis as revealed in this study were 17.6% (554/3144) and 13.3% (8547/64,435), respectively. Specifically, 15.8% (7178/45,363) seroprevalence of brucellosis was recorded in northern Nigeria as against 8.7% (1902/21,740) seroprevalence in the southern part. It also indicated that 78.7% of the detected brucellae were un-typed. The Brucella species detected were B. abortus (15.2%), B. melitensis (4%), B. suis (1.8%), and B. canis (0.4%). This study revealed that brucellosis is endemic in Nigeria. Culture and molecular methods for detecting brucellosis and reports on antimicrobial susceptibility testing remain a conjecture. This review will help researchers redirect their research focus and serve as a guide for policymakers on measures for managing brucellosis in Nigeria.

“…However human brucellosis seroprevalence in abattoir workers will vary depending on the prevalence of the disease in livestock (54,55), infrastructure, training, sanitation and/or hygiene standards at abattoirs. This includes awareness of the disease and training on the use of PPE (20,21,22,25,54,55) job description ( slaughterers or butchers and workers with cut injuries have higher risks (16,53)) and consumption of unpasteurized milk products and raw meat (22,23,24,56). Risk factors differed from study to study indicating that these factors influence the disease prevalence in humans differently in each area.…”

“…Brucellosis is a complex disease humans can also become infected indirectly by consuming raw or undercooked meat, raw and unpasteurized milk, or milk products (16). A wide variety of risk factors that predispose abattoir workers to infection were identified in studies and include length of days at work; unknown health status of slaughtered animals; non-use of PPE; splash of animal secretion on the face; hand cut injuries during work; lack of hygienic measure in the work environmental; and poor knowledge and attitude of the workers and their perception of zoonoses as occupational hazards (16,19,20,21,22,23,24,25,26). These studies were conducted in various countries/regions, each with its unique zoonotic disease profile in abattoir facilities that determine the risk factors identified in each study.…”

Abattoir workers are liable to zoonotic infections from animals and animal products, pri-marily to diseases with asymptomatic and chronic clinical manifestations in animals such as brucellosis. No published reports exist on the seroprevalence of brucellosis in abattoir workers in South Africa. Therefore, this cross-sectional study was conducted to estimate the occurrence and risk factors for Brucella exposure in abattoir workers in Gauteng Province. A total of 103 abattoir workers and managers from six abattoirs, where brucellosis-positive slaughtered cattle and sheep were previously detected, were interviewed, and tested with serological assays using the Rose Bengal test (RBT), BrucellaCapt, and IgG-ELISA. A pre-tested questionnaire was administered to consenting respondents to obtain infor-mation on risk factors for brucellosis. Of the 103 respondents tested, the distribution of fe-male and male workers was 16 (15.5%) and 87 (84.5%), respectively. The seroprevalence for exposure to brucellosis was 21/103 (20.4%, 95%CI: 13.1-29.5) using a combination of RBT, BrucellaCapt, or IgG-ELISA. For test-specific results, seroprevalences by RBT, BrucellaCapt, and IgG-ELISA were 13/103 (12.6%, 95%CI: 6.9-20.6), 9/103 (8.74%, 95%CI: 4.1-15.9) and 18/103 (17.5%, 95%CI: 10.7-26.2), respectively. Low-throughput abattoirs were identified as associated risk as 29.3% of workers were seropositive compared to 12.7% of workers in high-throughput abattoirs, which highlights that direct contact at abattoirs poses higher risk to workers than indirect and direct contact outside abattoirs. This study confirmed the occurrence of Brucella spp. antibodies among abattoir workers in South Africa, possibly due to occupational exposure to Brucella spp. and highlight the occupational hazard to workers. Furthermore, findings underscore that abattoir facilities can serve as points for active and passive surveillance for indicators of diseases of public health importance. We recommend periodic implementation of brucellosis testing of abattoir workers country-wide to establish baseline data for informing appropriate preventive practices and reduce the potential burden of infection rate among these high-risk workers.

Abortifacient pathogens such as bacterial [Brucella spp., Listeria spp., Leptospira interrogans ser., Coxiella burnetii, Campylobacter spp., Anaplasma spp., Chlamydia spp.], mycotic [Aspergillus spp. and Candida spp.], protozoan [Toxoplasma gondii, Neospora spp.], and viral [Blue tongue virus (BTV), Schmallenberg virus (SBV), Bovine viral diarrhea virus (BVDV), and Peste des petits ruminants virus (PPRV)] pathogens are challenges for the productive and reproductive performance of ruminants (cattle, sheep, and goats) globally. No comprehensive report on epidemiology, associated risk factors, or economic burden of these infectious pathogens is available for Nigeria. This review estimated the distribution and burden of abortive pathogens in ruminants in Nigeria for the last twenty-two years (2000-2022). Research articles reporting the detection of any of the above-mentioned abortive pathogens in ready-to-slaughter ruminants (RTSR), sick ruminants (SR), and ruminants with abortive history (RWAH) in Nigeria were accessed using different repositories, including Google Scholar, Proquest, PubMed, ResearchGate and Scopus to determine the prevalence, spatial distribution, and associated risk factors. From a total of 140 articles selected for this review, eight bacterial, four viral, two parasitic, and two mycotic infectious agents were reported for Nigeria. This study reveals a prevalence of 28.2% viral agents, 14.43% bacterial pathogens, 14.24% protozoans, and 28.1% fungal agents in the reported tested samples. Brucellosis was the most often reported among bacterial diseases, followed by leptospirosis and listeriosis. PPRV infection was the most common viral disease, followed by BTV. Additionally, two parasitic diseases, neosporosis and toxoplasmosis, and two mycotic diseases, aspergillosis and candidiasis, were reported. In this study, stillbirth and abortion were recorded in 49.2% of sheep with PPRV, 58.95% in goats with Chlamydophila abortus and PPRV, and 6.4% in cattle with Brucella abortus and Histophilus somni infections. Lack of vaccines, open markets, and extensive husbandry systems were among the risk factors associated with different abortive pathogens. This study is a useful tool for researchers and government officers in risk assessment and management of livestock to improve livestock production in Nigeria
