Molecular identification and thermoresistance to boiling of Nocardia farcinica and Nocardia cyriacigeorgica from bovine bulk tank milk BJM
Condas,L.A.Z.; Ribeiro,M.G.; Gonoi,T.; Matsuzawa,T.; Yazawa,K.; Motta,R.G.; Franco,M.M.J.; Listoni,F.J.P..
Two strains of Nocardia spp. were isolated from bovine milk of two individual bulk tank. Molecular identification classified the strains as Nocardia farcinica and Nocardia cyriacigeorgica. The thermorresistance to boiling of the isolates was carried out and was observed bacterial growth after boiling. Our findings indicate the potential risk of pathogen transmission to humans through contaminated milk with Nocardia spp.

Identification of Methicillin-Resistant Staphylococcus aureus in Bulk Tank Milk Ciênc. Tecnol. Aliment.
KEYVAN,Erhan; YURDAKUL,Ozen; DEMIRTAS,Ahu; YALCIN,Halil; BILGEN,Nuket.
Abstract Staphylococcus aureus is the leading cause of intoxications in humans. Also, methicillin-resistant S. aureus (MRSA) is an emerging problem in food-producing animals. The presence of MRSA in milk may create a risk to public health. The aim of this study was to evaluate the presence of MRSA in bulk tank milk samples. One hundred and twenty bulk tank milk samples were analyzed using the convenient sampling method. The isolates were confirmed by real-time polymerase chain reaction (RT-PCR) targeting nuc and mecA gene in S. aureus. Antibiotic resistance profiles of the isolates were tested by disc agar diffusion method. In the current study, S. aureus was detected in 44 (36.66%) of the samples. The presence of the mecA gene was found to be positive in...
