Farm biosecurity is considered an important component of “One Health”. Biosecurity measures are crucial for preventing and controlling outbreaks and spread of diseases on farms. Protection motivation theory (PMT) links perception of risk and coping ability with taking preventive actions. Based on field survey data of pig farmers, this study utilizes OLS and mediating effect model to explore the impact and mechanism of epidemic experiences on farmers' implementation of biosecurity measures. The research findings are as follows: first, epidemic experiences significantly promote farmers' implementation of biosecurity measures. The conclusion remains robust after addressing potential endogeneity issues. Second, epidemic experiences, through accumulated experience, further encourage farmers to implement biosecurity measures. Third, the impact of epidemic experiences on farmers' biosecurity behavior shows heterogeneity in farm size. Compared to small-scale farmers, epidemic experiences have a greater promoting effect on biosecurity behavior of professional farmers. Therefore, emphasizing farmers' epidemic experiences, enhancing biosecurity training, and increasing farmers' awareness are of significant importance in promoting farmers' implementation of biosecurity measures.

Leptospirosis, a widespread zoonotic disease caused by Leptospira spp., affects approximately 1 million people annually and causes about 58,000 deaths worldwide. This study examines the epidemiology of leptospirosis in Ukraine from 2018 to 2023, focusing on the impact of weather and geographical factors on disease transmission. Data from the Ukrainian Centre for Disease Prevention and Control, the Ukrainian Hydrometeorological Center, and the State Agency of Water Resources of Ukraine were analyzed. The country was divided into five regions: North, East, Center, South, and West. For the visualization, but not the quantitative analyses, the notification rate (NR) of leptospirosis was classified into three categories: low, moderate, and high.
The highest NR were in Zakarpattia, Ivano-Frankivsk, Khmelnytskyi, Mykolaiv, and Kherson regions, with Zakarpattia having the highest rate. We analyzed whether various weather parameters—such as average annual temperature, precipitation, days with precipitation ≥1 mm, and relative humidity—were associated with the notification rate (NR) of leptospirosis, but no significant correlations were detected.
However, a significant positive correlation was observed between higher density of the river network and NR (Kendall's rank correlation, r = 0.65, p = 0.0005), indicating that geographical factors may play an important role in Leptospira transmission. Additionally, we found a significant correlation between monthly air raid alarm frequency and the NR of leptospirosis cases in 2023. Case reports of individuals contracting leptospirosis in bomb shelters further support the hypothesis that air raid evacuations impact leptospirosis epidemiology. Further investigation is needed to fully understand this relationship and its implications.

Background
The pet and aquaria trade is a pathway for the introduction of invasive alien species (IAS) into sensitive Caribbean ecosystems. This study aims to assess the impact of this trade on IAS management in the Caribbean.
Methods
A multipronged approach was used, involving stakeholder engagement, trade flow analysis, questionnaires, a regional IAS workshop, and a One Health Invasive Alien Species Prioritization (OHIASP) method, to examine the pet and aquaria trade in Barbados and the Organisation of Eastern Caribbean States (OECS). These methods allow for a comprehensive tool necessary to prioritise IAS challenges worldwide particularly in Barbados and the OECS.
Results
The study assessed seven Caribbean countries: Barbados, St. Lucia, Grenada, Dominica, St. Kitts and Nevis, St. Vincent and the Grenadines, and Antigua and Barbuda. Barbados reported the highest annual import values for pets (USD $371,604) and aquaria (USD $450,860) using data from 2016 to 2020. The species range was very narrow and likely a reflection of data collection systems. Trinidad and Tobago was the primary regional source for pet and aquaria imports. In total, 35 IAS were chosen for prioritization. Based on their weighted score, prioritized IAS were ranked in order of relative importance using a one-to-five selection scale. A priority list of 13 IAS was identified from the pet/aquaria imported into Barbados and the OECS.
Conclusions
This marks the first ever study using an OHIASP tool for examining, quantifying and ranking IAS risks in pet and aquaria trade pathways. This can assist zoonotic disease risk prioritization where necessary. Effective IAS management in the Caribbean requires multipronged approaches, data and information systems that integrate indigenous knowledge, leverage digital tools, and build community ownership, to overcome inherent regional vulnerabilities.

Simulating resistant bacteria transmission in livestock informs surveillance strategies for emerging threats like Carbapenem-resistant Enterobacteriaceae (CPE), aiding targeted surveillance and detecting CPE through active methods. We employed a simulation model to assess three potential scenarios for introducing CPE: 1) a single import of live animals, 2) the use of contaminated feed, and 3) multiple imports of live animals. Employing the SimInf package, we constructed a population model for broiler production, encompassing rearing farms, multiplier farms, hatcheries, and broiler farms. Subsequently, we introduced CPE and allowed it to spread throughout the population using the Susceptible-Colonized (Infectious)-Susceptible model. The model ran for 10 years with 100 runs.
In the single import scenario, 1–2 rearing and multiplier farms saw major outbreaks in all 100 runs, while the broiler farm experienced major outbreaks in only 10 out of 100 runs; in the feed scenario, major outbreaks occurred in rearing farms in 32 runs and in multiplier farms in 26 runs, with major outbreaks in broiler farms observed in all 100 runs; in the multiple import scenario, outbreaks in rearing and multiplier farms happened in all 100 runs, with these major outbreaks reaching the broiler farm in 91 out of 100 runs. CPE transmission from imported or colonized broilers is rapid but short-lived within the broiler population, contrasting with the sporadic and prolonged emergence of CPE from contaminated feed, resulting in lower cumulative probabilities of detection from imported or colonized animals (0–0.50) compared to contaminated feed (0.9–0.97) over a 10-year period. Sensitivity analysis indicated that key outcomes such as farm outbreaks, chicken colonization, and outbreak duration are highly correlated with age-associated reductions in transmission (ψ).

Background
Chickens are an important source of animal protein, nutrition, and income in many low- and middle-income countries (LMICs). They are also a major reservoir of enteropathogens that contribute to the burden of illnesses among children. Food systems present a risk for transmission of enteropathogens from poultry to humans, but there is a lack of population-level data on the pattern of purchase, ownership, and consumption of live chickens and their products in LMICs to better characterize that risk.
Methods
To assess chicken purchase, ownership, and consumption practices, we conducted a population-based survey using a structured questionnaire in Maputo, Mozambique in 2021. Multi-stage cluster sampling was used to obtain a representative sample of households in our study area. To minimize sampling bias and ensure a representative sample, we applied survey weighting using district-level population data and estimated weighted population-level values.
Results
Heads of 570 households in Maputo completed our survey. Approximately half of these households purchased broiler chicken meat (weighted percentage of households: 44.8 %) and eggs (46.5 %) in the previous week of the survey date, while indigenous chicken meat was less popular (1950, 1.1 %). The most common source of chicken products was corner stores (i.e., small convenience shops on streets), followed by wet markets. Live chickens were raised by 15.6 % of households, and chicken feces were observed on the floor or ground at the majority of these households during house visits.
Discussion
Our findings suggest that poultry provides a major source of animal protein in this setting. Given the predicted growth of poultry farming in LMICs in the coming decades, implementing One Health-based food safety measures at primary sources of chicken products, such as corner stores and wet markets, will be critical to controlling zoonotic pathogen transmission risks.

In the 21st century, three betacoronaviruses (SARS-CoV, MERS-CoV and SARS-CoV-2) have emerged in humans worldwide as a result of animal spillover, causing severe respiratory infections and resulting in more than seven million deaths. In 2013, a novel Betacoronavirus closely related to MERS-CoV (Betacoronavirus cameli) was discovered in European hedgehogs (Erinaceus europaeus), raising questions on the possibility of hedgehog-to-human transmission. Hence, the present study aimed to investigate and characterize the presence and genetic diversity of coronaviruses in hedgehogs from Portugal, as well as their potential for cross-species transmission. To achieve this, fecal samples from 110 hedgehogs at two recovery centers and one environmental non-governmental organization were tested for coronaviruses using a broad-spectrum nested RT-PCR assay targeting the RdRp gene. Of these samples, 24.5 % tested positive, most belonging to the Betacoronavirus genus. However, the present study also reports, for the first time, Alphacoronaviruses in hedgehogs, showing 100 % identity with a Bat coronavirus (a variant of Alphacoronavirus miniopteri). The genome sequencing of one betacoronavirus-positive sample yielded 65 % of a full-length genome, with the closest homology (93.5 %) to Betacoronavirus erinacei from the United Kingdom. Computational protein-protein docking studies predicted the binding affinity between the spike protein of hedgehog coronavirus and cell receptors of mammal species that interact with hedgehogs. The results obtained raise the question of whether hedgehog CoV uses the same receptor as MERS-CoV or a different receptor to enter host cells. Thus, this study enhances our understanding of the epidemiology of coronaviruses, emphasizing the need for further investigation into cross-species transmission risks.

The mecC gene conferring methicillin-resistance has always been found on a SCCmec type XI element and is largely restricted to the few clonal complexes CC130, CC1943, CC425, CC49 and CC599. The occurrence of the mecC gene in many different hosts highlighted its One Health importance, even though European hedgehogs (Erinaceus europaeus) are considered its natural reservoir, most probably because of the selective pressure imposed by beta-lactam-producing dermatophytes (Trichophyton erinacei) that colonize the skin of these mammals. Surprisingly, while the presence of T. erinacei on the French territory has been proven, no mecC-positive methicillin-resistant Staphylococcus aureus (MRSA) isolate has been reported yet from hedgehogs. We thus sampled 139 hedgehogs brought to a wildlife center; 128 were S. aureus carriers and 25 (18.0 %) presented a MRSA isolate, of which 21 (15.1 %) displayed the mecC gene. All 161 S. aureus collected were whole-genome sequenced. The mecC-MRSA belonged to the classical CCs, i.e. CC130, CC1943 and CC49. The majority (98/139, 70.5 %) of the methicillin-susceptible Staphylococcus aureus (MSSA) isolates also belonged to these three CCs. A phylogenetic comparison with mecC-MRSA isolates from all over Europe and New-Zealand showed local adaptations, despite the fact that they all belonged to the same CCs. The acquisition of the SCCmec type XI element by a concomitant MSSA could not be observed in the same animal, but such a transfer might be suggested since identical clones were identified, one MSSA and one MRSA, though in different animals. In parallel, we conducted a detailed analysis of the SCCmec type XI element as well as specific virulence factors (a tst variant and the vwbSaPI gene). Results led us to hypothesize that the mecC gene might be acquired through selective pressure of T. erinacei on MSSA, some of which were acquired a long time ago from ruminants and are now colonizing the skin of the hedgehogs.

Results led us to hypothesize that the <em>mecC</em> gene might be acquired through selective pressure of <em>T. erinacei</em> on MSSA, some of which were acquired a long time ago from ruminants and are now colonizing the skin of the hedgehogs.</div></div>","PeriodicalId":19577,"journal":{"name":"One Health","volume":"19 ","pages":"Article 100938"},"PeriodicalIF":4.1,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142701246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background
Temperature and precipitation have previously been associated with Salmonella infections. The association between salmonellosis and precipitation might be explained by antecedent drought conditions; however, few studies have explored this effect.
Methods
Using an ecological study design with public health surveillance, meteorological (total precipitation [inches], temperature [average °F], Palmer Drought Severity Index [PDSI, category]), and livestock data we explored the association between precipitation and Salmonella infections reported in 127/141 counties from 2009 to 2021 in the Southwest, US and determined how this association was modified by antecedent drought. To explore the acute effect of precipitation on Salmonella infections we used negative binomial generalized estimating equations adjusted for temperature with a 2-week lag resulting in Incidence Rate Ratios (IRR). Stratified analyses were used to explore the effect of antecedent drought and type of animal density on this association.
Results
A one inch increase in precipitation was associated with a 2 % increase in Salmonella infections reported two weeks later (IRR: 1.02, 95 % CI: 1.00, 1.04) after adjusting for average temperature and PDSI. Precipitation following moderate (IRR: 1.22, 95 % CI: 1.17, 1.28) and severe drought (IRR: 1.16, 95 % CI: 1.10, 1.22) was associated with a significant increase in cases, whereas in the most extreme drought conditions, cases were significantly decreased (IRR: 0.89, 95 % CI: 0.85, 0.94). Overall, more precipitation (above a 30-year normal, the 95th and 99th percentiles) were associated with greater increases in cases, with the highest increase following moderate and severe drought. Counties with a higher density of chicken and beef cattle were significantly associated with increased cases regardless of drought status, whereas dairy cattle, and cattle including calves had mixed results.
Discussion
Our study suggests precipitation following prior dry conditions is associated with an increase in salmonellosis in the Southwest, US. Public health is likely to see an increase in salmonellosis with extreme precipitation events, especially in counties with a high density of chicken and beef cattle.

In the last 6 years, Italy accounted for 36 % of the total autochthonous European West Nile virus (WNV) cases reported to ECDC. Since 2001, the country put in place a multi-species national surveillance plan. The plan was enhanced in 2020 by adopting a fully integrated “One Health” approach, including human, wild bird, equine, and mosquito surveillance for the early detection of WNV. In this context, the systematic acquisition of whole viral genetic information from human patients and animals is fundamental to obtain an in-depth knowledge on the patterns of virus evolution and transmission and to gain insights on the role virus genetics in morbidity and mortality, The purpose of this pilot study was thus to design a One-Health surveillance framework based on the genomic surveillance of WNV circulating at the vector-human-animal interface, in the endemic territory of Romagna (North-Eastern Italy) during the 2023 transmission season. Whole genome sequencing (WGS) analyses confirmed the circulation of WNV lineage 2 showing high nucleotide and amino acid identity of 99.82 % and 99.92 % respectively among viral sequences from human patients, vectors and birds. All the sequences clustered with other Italian strains in the Central and Southern European clade with robust bootstrap support and BLASTn identity exceeding 99.7 %. The highest nucleotide identity was observed with sequences from Emilia-Romagna and Veneto regions (Italy), confirming a local virus circulation and overwintering of WNV lineage 2 with a confined virus spread and no (or limited) external introduction of viral strains. Our results, support the adoption of a One Health approach to WNV surveillance, based on WGS and integrating the clinical diagnosis, epidemiology, and genomic characterisation, to create a suitable operational process for the characterisation of autochthonous and imported Arboviruses circulating in Romagna to effectively integrate the already established surveillance plan.

Although human malaria is endemic in the Brazilian Amazonian region, autochthonous cases are registered regularly outside this region in areas under the couverture of the Atlantic Forest biome. The infecting species in the Atlantic Forest was initially believed to be the classical Plasmodium vivax. However, these locations have epidemiological characteristics that contribute to maintaining zoonotic monkey malaria, showing a great adaptation to different hosts, and many years later, it was discovered that almost all human malaria cases in the Atlantic Forest correspond to P. simium zoonosis. This review reported the history of discovering human infections by parasites originating from non-human primates in Brazil. It also examines epidemiology and underscores the need for specific preventive measures in the malaria elimination era. The data gathered so far have demonstrated that several factors enable zoonotic disease transmission in these areas. Given the facilitating ecological aspects involved and the scarce knowledge of the disease by the populations of the non-endemic area, this scenario adds difficulty to the challenge of eliminating malaria in Brazil.
