Abstract

This case report describes the microbiological isolation and characterisation of Salmonella enterica serovar Typhimurium (4,12:i:1,2) from the milk of a six-year-old Holstein cow with chronic mastitis and infertility. Milk and faecal samples collected during a farm investigation were subjected to bacteriological analysis in accordance with FDA and ISO standards, respectively. The isolate was identified using the BD PhoenixTM 100 automated system and subsequently serotyped at the Etlik Veterinary Control Central Research Institute. Molecular confirmation was performed by detecting the invA gene, and antimicrobial susceptibility was assessed by disc diffusion. This report documents a rare microbiological finding of S. Typhimurium in milk, highlighting milk as a potential source of transmission and emphasising the importance of comprehensive microbiological surveillance in dairy herds.

Özet

Bu vaka raporu, kronik mastitis ve infertilite bulunan altı yaşındaki bir Holştayn ineğin sütünden Salmonella enterica serovar Typhimurium’un (4,12:i:1,2) mikrobiyolojik izolasyonu ve karakterizasyonunu tanımlamaktadır. Çiftlik ziyareti sırasında toplanan süt ve dışkı örnekleri, sırasıyla FDA ve ISO standartlarına uygun olarak bakteriyolojik analize tabi tutulmuştur. İzolat, BD PhoenixTM 100 otomatik tanımlama sistemi kullanılarak identifiye edilmiş ve ardından Etlik Veteriner Kontrol Merkezi Araştırma Enstitüsü’nde serotiplendirilmiştir. Moleküler doğrulama, invA geninin saptanması ile gerçekleştirilmiş; antimikrobiyal duyarlılık ise disk difüzyon yöntemiyle değerlendirilmiştir. Bu rapor, sütte S. Typhimurium’un nadir görülen bir mikrobiyolojik bulgu olduğunu ortaya koymakta, sütün potansiyel bir bulaş kaynağı olabileceğine dikkat çekmekte ve süt sığırı işletmelerinde kapsamlı mikrobiyolojik sürveyansın önemini vurgulamaktadır.
