As a result of unclear etiology, frequently, multidrug-resistant bacteria are identified. This study investigated bacterial isolations and an antimicrobial susceptibility test (AST) in chronic rhinitis in cats. The medical records of 395 cats with chronic URT signs were reviewed at the Kasetsart University Veterinary Teaching Hospital (KUVTH) between 2016 and 2021 to survey the underlying causes of URT. Then, apart from rhinitis, other causes were excluded to identify the bacterial species and antimicrobial susceptibility. The results indicated that the most frequent finding was neoplasia, followed by rhinitis and anatomical defects. Furthermore, the only significant association was between the age range and disease group, with gender, FIV, or FeLV infection not being significant. Rhinitis was 4.7 times more likely to occur than neoplasia in younger and young adult cats in the age range &lt; 1\u20133 years compared to the group &gt; 10 years. The main bacterial species was the Pseudomonas species. Antimicrobials with a susceptibility rate of more than 90% were amikacin, gentamicin, ciprofloxacin, norfloxacin, marbofloxacin, imipenem, and meropenem. In conclusion, rhinitis was the second most common chronic URT disease in cats and was more common in younger and young adult cats. The predominant bacteria with AST in this study reflect the antimicrobial resistance situation. Thus, antimicrobial usage should follow antimicrobial use guidelines first.<\/jats:p>","DOI":"10.3390\/ani12121572","type":"journal-article","created":{"date-parts":[[2022,6,18]],"date-time":"2022-06-18T09:51:11Z","timestamp":1655545871000},"page":"1572","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Investigation of Bacterial Isolations and Antimicrobial Susceptibility of Chronic Rhinitis in Cats"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8327-4194","authenticated-orcid":false,"given":"Wannisa","family":"Meepoo","sequence":"first","affiliation":[{"name":"Kasetsart University Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Kamphaeng Saen Campus, Kasetsart University, Nakhon Pathom 73140, Thailand"},{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine, Kasetsart University, 50 Ngamwongwan Rd., Bangkok 10900, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3253-8297","authenticated-orcid":false,"given":"Tassanee","family":"Jaroensong","sequence":"additional","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine, Kasetsart University, 50 Ngamwongwan Rd., Bangkok 10900, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3245-5707","authenticated-orcid":false,"given":"Chantima","family":"Pruksakorn","sequence":"additional","affiliation":[{"name":"Department of Veterinary Microbiology and Immunology, Faculty of Veterinary Medicine, Kasetsart University, 50 Ngamwongwan Rd., Bangkok 10900, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2426-0961","authenticated-orcid":false,"given":"Jatuporn","family":"Rattanasrisomporn","sequence":"additional","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine, Kasetsart University, 50 Ngamwongwan Rd., Bangkok 10900, Thailand"},{"name":"Faculty of Veterinary Medicine, Kasetsart University Veterinary Teaching Hospital, 50 Ngamwongwan Rd., Bangkok 10900, Thailand"},{"name":"Center for Advanced Studies for Agriculture and Food, Kasetsart University Institute for Advanced Studies, Kasetsart University, Bangkok 10900, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"736","DOI":"10.1177\/1098612X19881847","article-title":"A retrospective study of more than 400 feline nasal biopsy samples in the UK (2006\u20132013)","volume":"22","author":"Ferguson","year":"2020","journal-title":"J.
