{"title":"Comparison of intradermal and serum testing for environmental allergen-specific immunoglobulin E determination in a laboratory colony of cats with naturally acquired atopic syndrome.","authors":"Julie Lefrançois, Colombe Otis, Maxim Moreau, Marike Visser, Lauren Bessey, Andrea Gonzales, Jean-Pierre Pelletier, Johanne Martel-Pelletier, Eric Troncy, Frédéric Sauvé","doi":"10.1111/vde.13232","DOIUrl":"10.1111/vde.13232","url":null,"abstract":"<p><strong>Background: </strong>Allergen testing is used to select antigens included in the desensitisation vaccine.

Healthy German shepherd dogs were contemporaneously sampled. Sites included the rectum, perianal skin and axilla. The microbiome was evaluated following sequencing of the V4 hypervariable region of the 16S ribosomal RNA (rRNA) gene.ResultsAlpha diversity was not significantly different between healthy and affected dogs at each of the three body sites (<jats:italic>p</jats:italic> &gt; 0.5), yet rectal and perianal beta diversities from affected dogs differed significantly from those of healthy dogs at Day 0 (<jats:italic>p</jats:italic> = 0.004). Rectal and perianal relative abundance of <jats:italic>Prevotella</jats:italic> spp. increased and perianal <jats:italic>Staphylococcus</jats:italic> spp. relative abundance decreased in affected dogs over time, coincident with lesion resolution.Conclusions and Clinical RelevanceChanges in lesional cutaneous and rectal microbiota occur in German shepherd dogs with perianal fistulas and shift over time with lesion resolution during immunomodulatory therapy. Further investigations of the role of cutaneous and enteric microbiota in the pathogenesis of perianal fistulas, and whether manipulation of microbial populations may ameliorate disease, are needed.","PeriodicalId":23599,"journal":{"name":"Veterinary dermatology","volume":"21 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140573336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
