It affects mainly cattle and is characterized by severe necrohemorrhagic myositis and myocarditis. While the disease has caused substantial economic losses in the past, the number of diseased cattle has been decreasing in the last 30 years. Subsequently, the status of blackleg has been officially changed in Switzerland and the disease is no longer reportable since 2022. Considering the potential persistence of C. chauvoei spores in the environment, blackleg may however still be prevalent in certain areas of the Canton of Bern, an important and large agricultural region of Switzerland. In this study, we evaluated both the spatio-temporal distribution of blackleg from 1992-2023 and the currently implemented prophylactic measurements used by veterinarians in the risk areas of the Canton of Bern. Our results show that most of the cases occurred in areas still defined as risk areas by the Cantonal Veterinary Office, however some occurred in areas no longer listed as risk areas since 2020. In parallel, veterinarians reported suspected cases in recent years as well as a decreased acceptance of vaccination by farmers in risk areas. The combination of lack of blackleg monitoring, reduced disease awareness, decreasing willingness of farmers to vaccinate and the long environmental persistence of C. chauvoei spores represent a risk for reoccurrence of the disease. Veterinarians practicing in once affected areas, in the Canton of Bern and elsewhere in Switzerland, should be aware of this and act accordingly once blackleg outbreaks are suspected.</p>","PeriodicalId":21544,"journal":{"name":"Schweizer Archiv fur Tierheilkunde","volume":"167 1","pages":"44-52"},"PeriodicalIF":0.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144609336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study offers an overview of cow-calf housing and management systems in Switzerland to provide insight into cows and calves' behaviour and use of barns' functional areas and to identify potentially problematic aspects of animal welfare within these systems. A total of 39 suckler cow farms and six farms with dairy dam-calf contact in Switzerland were each visited once. Welfare-relevant aspects of barn construction were measured, and the farmers on each farm were surveyed regarding their management and experiences. Animal behavioural observations were made using scan sampling (18 times every 10 minutes over a 3-hour time span) to analyse the animals' distribution and use of a barn's functional areas. Considerable farm-specific variance was found in how the farms managed and housed their livestock. About half the farms had drinking troughs over 60 cm in height, wich raised questions about the ability of these farms' young calves to access water. All farms had installed lying areas for calves, which varied in size, number and location. In the systems with a calf creep area separated from the lying area, the number of cows lying during observation was 10 % less (n = 11; 34,5 %) than the number of cows lying in the systems with a calf creep area in front of the cubicles (n = 13; 44,6 %; p = .063).

A correct diagnosis of this preclinical phase and identification of cardiac enlargement should be carried out in order to advise appropriate medical treatment. When echocardiography is not available or declined by the dog's owners, alternative methods to identify the disease and predict clinically relevant cardiomegaly, can be performed. Among these, cardiac auscultation and assessment of heart murmur intensity, cardiac dimensions obtained by thoracic radiography, by means of vertebral heart size, and cardiac biomarkers, in particular N-terminal pro-B-type natriuretic peptide (NT-proBNP), can be carried out as single tests or in combination, in order to identify dogs with increased risk of congestive heart failure, and needing an early treatment with pimobendan. In particular, a heart murmur intensity ≥3/6 (moderate or louder), a vertebral heart size ≥11,5 units obtained from a latero-lateral thoracic radiographic view, and plasma concentrations of N-terminal pro-B-type natriuretic peptide value > 1100 pmol/l, are findings that might suggest presence of clinically relevant cardiomegaly with a good specificity.

The altered cell adhesion molecule resulting from this point mutation is responsible for an impaired tissue of CD4 T lymphocytes from the blood to intestinal tissue. The aim of this study was to assess the allelic frequency of this deleterious variant in the local Holstein population and to clinically examine ten BLIRD-affected Holstein cattle from Switzerland in order to characterise the phenotype of this new hereditary disease, which is still unknown to the veterinary community. BLIRD was associated with severely impaired animal health in the rearing phase and significantly reduced animal welfare due to weakened immune defences, below-average development and recurrent diarrhoea. Further examinations revealed increased leucocyte values and a slightly increased average age at first calving. Affected homozygous animals are labelled internationally as BLIRD-carrier homozygous (LRS), BLIRD-carrier heterozygous (LRC) and BLIRD-free (LRF). An obvious inbreeding practice was clearly demonstrated by the pedigree analysis of the ten animals, which all trace back to the potential founder bull. Herein, BLIRD has been detected and described in Switzerland for the first time. The ITGB7 variant allele has a frequency of 2,1 % in the current Swiss Holstein population, which is below the level of the cholesterol deficiency (CD)-associated apolipoprotein B (APOB) variant allele with a frequency of 3,9 %. Although relatively rare, attention should be paid to the BLIRD genotype when mating in order to exclude further affected animals.
