During the study period, a total of 676 cases of rabies were registered, with 60.10 % among wild species, 31.52 % among domestic (companion) animals, and 7.51 % among livestock animals. The transmission of rabies in the study area is especially driven by wild animals, particularly the red fox (<em>Vulpes vulpes</em>). Livestock forms a separate population that hardly can present a link of the rabies virus transmission but rather may be sought as an indicator of the virus presence in animals. A regression model with a good predictive power (R²=0.63) revealed the number of settlements, population density, population size of foxes and road length as the main explanatory factors for the number of cases of rabies by administrative units. ARIMA, which stands for Autoregressive Integrated Moving Average Model, was used for short-term time-series-based forecasting of animal rabies cases in the districts of the Nizhny Novgorod region. According to the ARIMA forecast, the number of rabies cases among all animals is expected to be 6–23, and particularly up to 15 cases in foxes for the season throughout 2025. This study provides important epidemiological information for veterinary services, including an expected number of animal rabies cases by population. This information may be of some interest in the planning of vaccination strategies.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"240 ","pages":"Article 106531"},"PeriodicalIF":2.2,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, geographic concentration and farming intensity has led to substantial disease-related losses, with underreported concerns and disease control from farmers. This study employs a qualitative methodology to gain insightful perspectives from Vietnamese striped catfish farmers on industry challenges and health management practices. Thematic saturation was sought through qualitative interviews with 44 participants (19 nursery, 21 grow-out, and 4 vertically integrated farms), operating at private- or company-scales across six major production provinces (Dong Thap, An Giang, Can Tho, Vinh Long, Ben Tre, and Long An). Data were thematically analysed using the Framework method, focusing on the intricate interplay between host, environmental factors, and pathogen that contributes to rising disease prevalence and impacts profitability. Farmers articulated distress over escalating disease severity and low survival rates, exacerbated by declining water quality and major technical barriers such as seedstock and broodstock quality. Historically reported diseases, including Bacillary Necrosis in Pangasius (BNP) and Motile Aeromonas Septicaemia (MAS), remained prevalent. However, recent escalation of jaundice and swollen swim-bladder disease in grow-outs, as well as tail-rot disease (<em>Flavobacterium columnare</em> infection) in nurseries, have caused significant economic losses. Larger company-scale farms employed more standardised health management plans and educated staff compared to smaller, experience-based private farms. Antibiotics were perceived as less effective with infrequent antibiotic sensitivity testing, particularly among private farmers, due to inaccuracy. A trend towards reduced usage of antimicrobials and increased preference for dietary solutions was observed, with many farmers describing efforts to avoid antimicrobials, especially near harvest. Common preventive measures include regular environmental treatments and supplementary diets. However, the sector lacks advanced preventative measures, such as vaccination and early detection methods, highlighting the need for improved access to veterinary support to sustain striped catfish farming in Vietnam.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"239 ","pages":"Article 106527"},"PeriodicalIF":2.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CanSpotASF describes the ASF surveillance in Canada. It enhanced the passive surveillance by adding new surveillance components one by one. The first enhancement was “the risk-based early detection testing (rule-out testing)” where cases with eligible conditions were tested for ASF virus (ASFv). The rule-out testing started in 2020 and we have over 3 years data in the Canada West Swine Health Intelligence Network (CWSHIN) data repository on ASFv rule-out testing. The objectives were to develop and assess a scenario tree model (STM) for ASFv freedom to support the claim that commercial swine in Western Canada were free from ASFv; to assess if the CWSHIN repository data may be useful in the STM; and to assess if the rule-out testing had contributed to more evidence of freedom from ASFv than we would have had with passive surveillance alone. To compare and assess different scenarios we used the model’s ability to accumulate evidence of freedom from the July quarter in 2020 to the July quarter in 2023 (13 quarters). We concluded that a method to assess the ability of a scenario and model to accumulate evidence of freedom, based on increasing probability of freedom that approached an equilibrium and a system sensitivity of at least 0.2–0.3, was useful. The CWSHIN data repository was critical to populate the model because it included both number of clinical assessments by herd veterinarians (from quarterly surveys); routine diagnostic data (pathology examinations) and ASF testing results from laboratories. The take home message was that the probability that a herd veterinarian will report a suspicion of ASF to the Canadian Food Inspection Agency (CFIA) (seVet) affected the outcomes of the STM. If the probability that a herd veterinarian reports to CFIA is low (seVet=0.01), then pathology examination and CanSpotASF will improve the STM outcomes. If the probability that a herd veterinarian reports to CFIA is high (seVet is 0.7 or higher), then there is no need for additional pathology and CanSpotASF testing. We expect the actual probability of reporting and subsequent value of additional pathology and testing to between these two scenarios.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"239 ","pages":"Article 106523"},"PeriodicalIF":2.2,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lung lesion evaluation at slaughterhouses by different scoring systems is commonly used to monitor respiratory diseases in swine. Concretely, cranioventral pulmonary consolidation lesions are associated with enzootic pneumonia (EP) caused by <em>Mycoplasma hyopneumoniae (Mhyo);</em> whereas haemorrhagic necrotizing pneumonia, mainly in the dorso-caudal lung lobes, and chronic pleuritis (CP) are associated with <em>Actinobacillus pleuropneumoniae</em> (<em>App)</em>. Despite the recent consideration of several statistical methods for modelling the temporal dynamics of diseases and the construction of monitoring systems, none have been applied to lung lesions data collected at slaughterhouses. Thus, this work aimed (1) to describe the temporal patterns of EP and CP-like lesions in Spain using time series methods to model the collected data on lung lesions at slaughterhouses; and (2) to construct and evaluate in quasi-real time a surveillance system for early detection of outbreaks and abnormal trends potentially related to both pathogens. In total, 16 time series were analysed including 3947 audits from 474 Spanish farms associated with 302 companies between 2016 and 2019. The monthly time series of the EP index between 2016 and 2019 in Spain (point estimate for Spain was −0.088 with an associated <em>p</em> = 0.073) and different Spanish subregions showed decreasing trend patterns (point estimates for Aragon was −0.028 with an associated <em>p</em> = 0.000 and for Catalonia was −0.064 with an associated <em>p</em> = 0.092), whereas the monthly time series of the CP index increased (point estimate for Spain was 0.004 with an associated <em>p</em> = 0.045 and for Aragon was 0.007 with an associated <em>p</em> = 0.000) over the same period. Additionally, the predictive performance of the estimated models was evaluated at quasi-real time using the data between 2020 and 2021.

We assessed the sampling sensitivity and specificity of a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) surrogate virus neutralization test (sVNT) and conventional virus neutralization tests (cVNT) to detect antibodies for ancestral and Omicron B.1.1.529 variants of SARS-CoV-2 in wild white-tailed deer (<em>Odocoileus virginianus</em>) and mule deer (<em>Odocoileus hemionus</em>).
