The Anigen Rapid, SNAP and truRapid tests consistently provided the strongest evidence to rule-in infection. The LR⁺ of the WITNESS test was approximately twelve times, nine times and two times lower than the SNAP, truRapid and Anigen Rapid LFIs respectively (Bayesian p-value 0.002, 0.004 and 0.02 respectively). Overall, a positive result from MKT or LFIs is suitable to rule-in infection in dogs raising clinical suspicion and would increase the post-test probability of infection similarly.

This study aimed to estimate and compare the diagnostic <em>Se</em> and specificity (<em>Sp)</em> of a Phage-Magnetic Separation (PhMS) qPCR assay against a qPCR-confirmed liquid culture for the early detection of MAP infection in young dairy calves. Using a Bayesian Latent Class Model (BLCM) that accounted for conditional dependence, we analyzed 528 fecal samples from dairy calves &lt; 60 days of age from 39 commercial herds in Chile. The model revealed that both tests have comparable moderate median <em>Se</em> (PhMS = 45 %; culture = 51 %) and high median <em>Sp</em> (PhMS = 98 %; culture = 100 %) for MAP detection. However, tests were strongly negatively correlated in MAP-infected animals (correlation coefficient, ρDPhMS,Cult = −0.66; 95 % Posterior probability interval [PPI]: −0.91 to −0.12). This strong negative correlation indicates that the tests tend to detect different subsets of the infected population, making them complementary when used in a parallel testing strategy to maximize joint sensitivity (<em>Sej</em>). The estimated mean true within-herd prevalence in calves was 13 % (95 % PPI: 8–22 %). Additionally, the <em>Sp</em> of PhMS-qPCR decreased in high-prevalence herds, possibly due to passive shedding of the pathogen. Critically, leveraging their complementary nature, a parallel interpretation of the tests achieved a high combined <em>Se</em> of 92 % (95 % PPI: 53–100 %), while maintaining a high <em>Sp</em> of 97 %. In conclusion, PhMS-qPCR and qPCR-confirmed liquid culture are complementary diagnostic tools.

We detected 183 and 141 unique FRDs at the market and campus sites, respectively. The FRD in the market area were significantly younger, exhibited lower sterilization rates, and tended to be in poorer physical condition compared to those in the campus area; differences in body condition and collar presence were not statistically significant. Population estimates using Huggin's heterogeneity models revealed a FRD population size of 252 individuals (using the Chao estimator in the Huggin’s model) at the market site, while campus estimates varied between 161 during morning transects and 153 during evening transects (using the Jackknife estimator) and with morning and evening combined (using the Chao estimator) of 164 FRD.

It is the primary cause of antimicrobial treatments and a major source of economic losses due to reduced performance, increased mortality, and high therapeutic costs. Early, non-invasive indicators of BRD are urgently needed to improve its timely detection and mitigate the negative impact on cattle health and farm economics. With a view to precision livestock farming, this study investigated whether the automatic recording of individual drinking behavior and water consumption could provide some useful indicators of early BRD detection during the critical adaptation period of beef cattle at the fattening unit. The study involved 92 Limousine cattle (64 bulls, 28 heifers) from six different batches imported from France between May 2021 and December 2022. An innovative electronic drinking station equipped with radio-frequency identification and flow sensors automatically recorded individual drinking events, water intake, and time spent drinking during the 4 weeks of adaptation at the fattening farm. During the same time period, individual cattle daily health checks were performed by the farm veterinarian, recording all therapeutic treatments for BRD. Forty-five of the 92 animals (49 %) received at least one treatment for BRD during the 4-week adaptation period. In most cases, the first treatment was administered within the first two weeks of arrival (11.2 ± 6.9 days). Animals treated two or more times for BRD exhibited persistently lower daily water intake compared with untreated animals (20.9 vs. 27.3 L/day, respectively), particularly during the first two weeks after arrival. Two days before treatment, affected animals showed a significant reduction in daily water intake compared with healthy ones, whereas daily drinking time and number of visits to the drinker remained unchanged. Risk analysis revealed that cattle with individual water intake below 20.8 L/day increased by over fourfold the odds ratio of developing BRD. Additionally, groups of beef cattle arriving during autumn–winter exhibited a higher BRD occurrence than those arriving in late spring or early summer. These outcomes encourage the use of automatic devices to monitor the individual drinking behaviour during the adaptation period, as they could help identify conditions in which animals may be at higher risk of developing respiratory diseases.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"247 ","pages":"Article 106772"},"PeriodicalIF":2.4,"publicationDate":"2025-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145804784","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}

The primary objective of this study was to develop and validate the Infectious Disease Vulnerability Index (IDVI) as a tool for assessing dairy farm vulnerability to disease, aimed at enhancing biosecurity strategies and prioritizing high-risk farms for targeted interventions. Survey data on biosecurity practices, farm management, and animal movement were analyzed using K-Prototypes clustering, dimensionality reduction, optimal cluster determination, stability assessment, and validation. The clustering analysis revealed three distinct farm clusters, characterized by low, medium, and high disease vulnerability index categories. Cluster quality was assessed using silhouette scores (mean = 0.69) and Davies-Bouldin Index (mean = 0.44), with bootstrap resampling (200 iterations) confirming stability, and Friedman’s Test showing statistically distinct risk clusters. Following permutation testing, the factors with the most impact on the infectious disease vulnerability clusters included specific farm characteristics such as organic status and the total number of dairy animals, animal movement practices including frequency of bull calf movements and the average number of heifers leaving the farm during a shipment, farm contacts including hunters and dead animal haulers, and farm biosecurity practices including farm equipment transport practices, engaging in dairy animal exhibitions, and not having quarantine facilities with water, feed, and air separated from other farm animals. The IDVI offers a promising measure of comparing disease risk profiles, validated through bootstrapped silhouette scoring, statistical analysis, and permutation importance analysis. By leveraging the IDVI, dairy farmers, veterinarians, and animal health authorities can identify high-risk farms, implement targeted interventions to improve biosecurity, reduce disease transmission, and consequently enhance their outbreak preparedness.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"247 ","pages":"Article 106770"},"PeriodicalIF":2.4,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145797033","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}

We hypothesized that integrating these diverse data sources would improve the ability of the model to accurately classify ketosis severity during the transition period.
