This study reports a rare case of <em>Salmonella enterica</em> subsp. <em>enterica</em> serovar Agona (<em>S.</em> Agona) infection in an 80-day-old pig presenting with polyserositis, meningoencephalitis, arthritis and omphalitis. In the bacteriological examination, a pure culture of <em>S</em><em>.</em> Agona was obtained from the fibrinous lesions, which enabled diagnosis. Additionally, immunohistochemical examination allowed confirmation of the septicaemic distribution of the bacteria. The findings suggest umbilical contamination as the probable infection route, differing from the usual fecal-oral transmission of <em>Salmonella</em>. Although non-enteric <em>Salmonella</em> infections have been documented in various species, this is the first confirmed case of <em>S.</em> Agona causing such lesions in pigs. This case highlights the importance of specific diagnostic approaches to accurately identify the aetiological agent, as clinical and pathological presentations may resemble other common bacterial infections in pigs.</div></div>","PeriodicalId":15520,"journal":{"name":"Journal of Comparative Pathology","volume":"223 ","pages":"Pages 1-4"},"PeriodicalIF":0.9,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145847625","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}

A 4-year-old female guinea pig presented with a firm, irregular shaped mass, measuring 6.6 cm in the largest axis, in the right mammary gland. Cytological examination suggested mammary carcinoma. Based on these results, a right inguinal mammectomy was performed. Histological examination revealed a biphasic neoplastic proliferation in the hypodermis consisting of epithelial cells in cribriform, papillary, tubule and nest arrangements, and malignant myoepithelial cells arranged in multidirectional bundles and nests, with marked anisocytosis and anisokaryosis. Immunolabelling was positive for GATA3 and Ckpan in the epithelial component and positive for p63 in the myoepithelial component. After 71 days, the patient developed severe dyspnoea and agitation, and chest radiography showed several rounded structures distributed multifocally throughout the lung parenchyma, the largest of them measuring 0.9 × 0.6 cm. Macroscopic and histological examinations revealed multifocal metastases in the lung parenchyma, multifocal suppurative pneumonia and severe diffuse pulmonary oedema, confirming the cause of death as respiratory failure due to lung metastases. A metastatic malignant adenomyoepithelioma was diagnosed on the basis of the macroscopic, histological and immunohistochemical findings.</div></div>","PeriodicalId":15520,"journal":{"name":"Journal of Comparative Pathology","volume":"223 ","pages":"Pages 13-16"},"PeriodicalIF":0.9,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145922979","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}
