Microbial agents in macroscopically healthy mammary gland tissues of small ruminants.

ABSTRACT:

Background

Health of mammary glands is fundamental for milk and dairy products hygiene and quality, with huge impacts on consumers welfare.

Methods

This study aims to investigate the microbial agents (bacteria, fungi and lentiviruses) isolated from 89 macroscopically healthy udders of regularly slaughtered small ruminants (41 sheep, 48 goats), also correlating their presence with the histological findings. Multinomial logistic regression was applied to evaluate the association between lesions and positivity for different microbial isolates, animal age and bacteria.

Results

Twenty-five samples were microbiologically negative; 138 different bacteria were isolated in 64 positive udders. Coagulase-negative staphylococci were the most prevalent bacteria isolated (46.42%),
