One Health Microbiology & Infection is an international peer-reviewed journal dedicated to advancing research on microbiology, infectious diseases, antimicrobial resistance, and the interconnected health of humans, animals, and the environment through a One Health approach.
Listeriosis is a significant zoonotic disease affecting ruminants and causing substantial economic losses in livestock production. Although numerous regional studies have been conducted in Türkiye, a comprehensive synthesis of available data has been lacking. The current study aimed to evaluate the epidemiology, clinical forms, diagnostic approaches, and regional distribution of animal listeriosis in Türkiye. Studies reporting clinical listeriosis in animals in Türkiye between 1980 and 2024 were included. Due to methodological heterogeneity, a descriptive-analytic approach was adopted. A total of 26 studies were included. Most studies were conducted in Eastern and Central Anatolia, regions with intensive ruminant farming and widespread silage use. Sample sizes ranged from 18 to 3,760 animals. The most frequently investigated species were sheep (n=13 studies) and cattle (n=9 studies), followed by goats, dogs, and horses. Molecular and culture-based studies generally reported low positivity rates (0–7.29%), whereas serological studies showed a substantially wider range (17–86.69%), suggesting past exposure rather than active infection. An exceptionally high culture positivity rate (66.6%) was reported in a small-scale investigation of an encephalitic outbreak, whereas 100% seropositivity was observed in limited farm-based screenings of horses and dogs. Both findings likely reflect context-specific findings from small samples rather than population-level prevalence. Clinically, encephalitic and abortive forms were predominant in small ruminants, whereas subclinical infections were frequently reported in cattle through serological surveillance. The available evidence indicates that contaminated silage is a major epidemiological risk factor, particularly in regions with prolonged winter feeding. Notably, national surveillance data remain scarce, and most studies were cross-sectional or case-based. In conclusion, animal listeriosis remains a significant health concern in Türkiye, particularly in ruminant-dense regions. Strengthening surveillance and expanding molecular diagnostics in primary animal production farms, along with integration within a One Health framework, are essential to better define the disease burden and reduce zoonotic risk.
Carbapenem‑resistant Enterobacteriaceae (CRE) are associated with high morbidity and mortality in humans due to very limited therapeutic options. This systematic review examines the prevalence and geographic distribution of CRE, as well as the associated genetic factors at the human-animal-environment interface in Africa. To extract information for this study, the Medical Subject Headings (MeSH) technique was used to identify studies that employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines, with a focus on original research articles. Additionally, this systematic review employed the CoCoPop (conditions, context, and population) framework to identify relevant articles. Search engines used to retrieve articles included Web of Science, Google Scholar, Scopus, ResearchGate, and PubMed. By August 2025, only eight articles from Africa met the search criteria and were included in the analysis. The observed prevalence of CRE across the heterogeneous studies was 18.58%. The animal domain exhibited the highest CRE prevalence (9.89%), followed by the human (6.06%) and environmental (2.63%) domains. Escherichia coli (58.35%) and Klebsiella pneumoniae (28.28%) were the predominant spp. among the reported CRE isolates. The highest gene prevalence was observed for blaOXA-48 (42%), followed by blaKPC (33%) and blaOXA-66 (9.78%). Geographically, North Africa had the highest prevalence (55.78%), followed by Eastern Africa (29.82%), whereas Southern Africa had the lowest prevalence (3.08%). Our study emphasizes the significant burden of CRE infections and genes, as well as their spread across human, animal, and environmental sectors in Africa. The simultaneous presence of CRE in these areas indicates potential interfaces, but current evidence does not permit a definitive assignment of specific transmission routes. Surveillance programs, research, infection prevention, and control measures from a One Health perspective should be implemented to inform interventions.
The One Health approach has emerged as a critical framework for addressing zoonotic diseases and infections during outbreaks worldwide. By recognizing the interconnectedness of human, animal, and environmental health, One Health promotes cross-sector collaboration essential to early detection, prevention, and response. However, translating this concept into practice requires more than policy endorsement; it demands operational integration, shared data platforms, and equitable partnerships that prioritize local leadership. From this point, we are delighted to announce the launch of the One Health Microbiology & Infection (One Health Microbiol. Infect.) journal, a dedicated platform for advancing research, innovation, and knowledge dissemination in the rapidly evolving fields of microbiology and infection within One Health insights.
