While IAV epidemiology has been extensively studied in large-scale production systems, data from Switzerland - characterized by small herds and limited live pig imports - remain scarce. This exploratory nationwide cross-sectional study aimed to assess the association between herd-level IAV detection and reported respiratory disease in pig herds, and to explore associations with husbandry-, animal-, and human health-related factors. Between November 2023 and April 2025, 25 Swiss pig herds with caretaker-suspected respiratory symptoms were investigated. In each herd, five nasal swabs were collected and analyzed by quantitative PCR. Herd managers completed an interview, and clinical examinations were performed. Overall, 56 % (95 % CI: 37,1 - 73,3) of herds tested positive for IAV, comparable to reports from other European countries. The estimated intra-herd detection rate was 49,6 % (95 % CI: 31,2 - 68,0). Respiratory disease outbreaks associated with IAV detection showed indications of seasonal variation, with no positive herds identified during summer. Across age groups, pigs aged 11-14 weeks had a higher likelihood of IAV detection, with 15,79-fold increased odds (95 % CI: 1,50 - 860,4), although with considerable uncertainty. The interpretation is limited by the small sample size, heterogeneous data, and reliance on single time-point qPCR detection. The results suggest that IAV detection in clinically apparent respiratory outbreaks may follow seasonal patterns in Swiss pig herds. Weaners and newly introduced fattening pigs may play a role in such respiratory outbreaks and could represent relevant targets for IAV surveillance in Switzerland. Continued monitoring and the implemen tation of appropriate control measures remain important given the virus's zoonotic potential and impact on pig health.</p>","PeriodicalId":21544,"journal":{"name":"Schweizer Archiv fur Tierheilkunde","volume":"168 9","pages":"143-156"},"PeriodicalIF":1.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148866113","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}

Around 7 % of the country's cattle are registered with the relevant breeding association. Switzerland boasts a high degree of genetic diversity, with 38 beef and dual-purpose breeds. This study aimed to systematically catalogue known recessive genetic defects and selected inherited traits of the most common Swiss suckler cow breeds and determine their prevalence. Worldwide, 67 monogenic recessive genetic defects have been identified in beef cattle. Of these, 42 - caused by 45 known gene variants - affect the ten most commonly kept suckler cow breeds in Switzerland. Currently, 40 causative gene variants for 37 genetic defects are routinely tested in Switzerland. No carrier animals have yet been identified for 13 of these variants. In contrast, heterozygous carriers were rarely identified for a total of 27 variants. The breed-specific allele frequencies exceeded 1 % for 14 harmful alleles. The causal variant for retinitis pigmentosa 1 was particularly widespread in Charolais and Angus cattle, as was the causal variant for developmental duplication in Angus cattle. Additionally, single homozygous affected animals were confirmed for the first time in Switzerland: tibial hemimelia in Galloway cattle and progressive ataxia in Charolais cattle. In addition to genetic defects, breeding-relevant monogenic traits such as muscle hypertrophy and hornlessness are also examined. These traits sometimes occur with high allele frequencies in several breeds and can therefore be targeted specifically in breeding programs.

Chronic gastrointestinal signs, poor growth, or episodes of hypovolemic shock should raise clinical suspicion. British Shorthair cats may be overrepresented among affected cats, and clinicians should be particularly alert when this breed presents with compatible signs. Definitive diagnosis requires an ACTH stimulation test, which should be performed prior to the initiation of any glucocorticoid treatment to avoid diagnostic interference. In clinically stable cats, baseline cortisol measurement may be used as an initial screening tool. However, as no feline-specific thresholds have been validated, the commonly used cut-off of >2 µg/dL (>55 nmol/L) to rule out hypoadrenocorticism should be interpreted with caution, as it may be less reliable than in dogs. Long-term management involves lifelong glucocorticoid replacement, typically using oral prednisolone. Cats generally require higher maintenance doses than dogs to maintain clinical stability. Mineralocorticoid deficiency is managed with subcutaneous administration of an extended-release desoxycorticosterone preparation (Zycortal®) given monthly at a starting dose of 2,2 mg/kg - substantially higher than canine doses. As an alternative, daily oral fludrocortisone acetate (Florinef® or Astonin®H) could be used at 0,01-0,02 mg/kg/day in selected cases. Regular monitoring of sodium and potassium levels is essential to adjust mineralocorticoid dosages and optimize treatment. Because affected cats cannot mount an adequate stress response, additional glucocorticoid supplementation («glucocorticoid boost») is required during stressful situations or concurrent illness. Owners must be educated about the signs of adrenal crisis, which can be more subtle and difficult to recognize in cats compared to dogs.

A 17-day-old female Swiss Holstein calf was presented for progressive, non-ambulatory weakness and inability to stand up without assistance. Clinical examination revealed generalized muscle atrophy and tremors, a wide-based stance, and inability to acquire the quadrupedal stance without assistance.

Pedigree analysis revealed that the affected calf was inbred and could be traced back to two known US MW carriers suggesting recessive inheritance.
