Spatial distribution and predictive risk of perpetuation of non-typhoidal salmonellosis in poultry farms and human communities: meta-analysis of data from Nigeria Abdullahi O. Sanni, Annelize Jonker, Olatunji O. Johnson, Ezra Gayawan, Aminu Shittu, et al. Geospatial Health, 2026 To gain insight into the common pathogenic, bacterial zoonosis represented by Salmonella infections in poultry and humans, we acted to determine salmonellosis prevalence in poultry and humans in Nigeria mapping hotspots. Using multi-sourced data, we conducted a meta-analysis to determine national and sub-national prevalence of salmonellosis in poultry from 2000 until 2020. Bayesian spatial joint modelling was used to map Non-Typhoidal Salmonella (NTS) infections in humans and poultry using climatic and demographic predictor variables. With the overall prevalence in poultry at 31.6%, the highest state-level prevalence rates were seen in Ogun (70.2%), Lagos (61.8%), Zamfara (58.2%) and Bauchi (57.1%). The North-West, South-West and South-South regions of Nigeria have the highest regional-level prevalence in poultry amounting to 38.5%, 36.9% and 33.6%, respectively. Thirteen states have higher than the average national prevalence (31.6%). While we found a negative association between NTS in humans and in poultry, the prevalence of diarrhoea in humans positively predicted salmonellosis in poultry. Not surprisingly, poultry populations positively predicted salmonellosis in other poultry populations. Higher numbers of human cases were predicted in the North, with more poultry cases in the South and in some North-Eastern states. The observed human NTS-poultry salmonellosis correlation is counterfactual to logic and plausibility as high poultry density and contamination in poultry are expected to predict human infection. The outcome pointed to under-reporting linked to self-treatment, under-testing in the public health and veterinary laboratory and lack of uniform primary healthcare services, particularly in under-served areas of Nigeria. Salmonellosis continues to be a serious burden, and provision of better health data is needed.
A Nationwide Survey on the Administration of Antibiotics in Companion Animals by Veterinary Practitioners in Nigeria Mary Idowu Olasoju, Pius Soladoye Olagunju, Aderonke Oluwakemi Alamu, Hezekiah Kehinde Adesokan, Taiwo Israel Olasoju, et al. World S Veterinary Journal, 2025 Antimicrobial use (AMU) in companion animals in Nigeria is underreported, raising public health concerns due to antimicrobial resistance (AMR). The present study aimed to establish baseline data on antimicrobial stewardship (AMS) among veterinarians treating small animals and, with a focus on prescription patterns and adherence to the World Health Organization (WHO) guidelines on the Highest Priority Critically Important Antimicrobials (HP-CIAS). A nationwide web-based cross-sectional survey was conducted between August and November 2022, utilizing an online self-administered questionnaire among 96 companion animal veterinarians (CAVs) in Nigeria. Data collected included veterinarians' demographics, diseases treated, prescribed antimicrobial agents, utilization of laboratory diagnostic tests, and veterinarians' knowledge of AMS and MAR. The survey was conducted using KoBo Toolbox (Cambridge, MA, USA), and the variables were analyzed with Epi Info version 7.1.3.10. Among the 96 respondents, 62.5% were male. The most frequently reported conditions were infectious and parasitic diseases (80.6%), followed by abscesses, injuries, and bite wounds (68.8%), and digestive system diseases (65.6%). The most commonly prescribed first-line antibiotics were oxytetracycline (81.4%) and metronidazole (56.9%), while ciprofloxacin (39.8%) and gentamicin (33.7%) were often prescribed as second-line antibiotics for companion animals. Approximately 38.3% of respondents reported 100% efficacy of the first antibiotic prescribed, while 90.3% were aware of laboratory test results before using antimicrobial agents. The data collected provides essential baseline insights into AMU patterns among CAVs in Nigeria, which are critical for guiding AMR interventions focused on responsible antimicrobial use, including the development of AMS initiatives and educational programs for veterinary practices nationwide.
Non-typhoidal Salmonella in Nigeria: do outcomes of ‘multisectoral’ surveillance, treatment and control justify the intervention costs? Abdullahi O. Sanni, Abdurrahman H. Jibril, Olubunmi G. Fasanmi, Oluwawemimo O. Adebowale, Alexander R. Jambalang, et al. International Journal of Veterinary Science and Medicine, 2024 Non-typhoidal salmonellosis (NTS) is significant and an economic burden in Nigeria. To determine whether investment in NTS control is economically justifiable, Outbreak Costing Tool (OCT) was used to estimate the robust funding of public and animal health systems for epidemio-surveillance and control of multisectoral NTS outbreaks in Nigeria. Health, production, and economic data were collected and used to populate the tool for evaluation. The multisectoral NTS burden for the year 2020 in Nigeria was US$ 930,887,379.00. Approximately 4,835 technical officers, and 3,700 non-technical staff (n = 8,535) were needed with an investment of >2.2 million work hours. The investment cost for NTS control was US$ 53,854,660.87. The non-labour-related cost was 89.21% of the total intervention costs. The overall intervention’s investment was 374.15% of the estimated national and subnational systems’ annual budget for diarrhoeal diseases, and the outbreak response period attracted the highest costs (53%) of the total intervention. In conclusion, intervention against NTS was beneficial (benefit – cost ratio: 17.29), hence justifying the need for multisectoral surveillance-response against NTS in Nigeria. Complex sectoral silos must give way to coordinated collaborations to optimize benefits; and over-centralization of health interventions’ associated delays must be removed through decentralized sub-national-focused framework that empowers rapid investigation, response, control, data collection, and analyses. It should assist anticipatory planning, and outbreak investigation and reduce critical response time. Anticipatory planning tools, when applied pre-emptively, can benefit budgeting, identify gaps, and assist in the delivery of cost-saving and effective measures against infectious disease.
