Isolation and identification of common bacteria causing subclinical mastitis in dairy goats

The purpose of the current study was to isolate and identify subclinical mastitis causing bacteria from milk samples of dairy goats. The milk samples from individual dairy goats were collected from several dairy goat farms around Kota Bharu, Kelantan. Major bacterial isolates were Staphylococcus spp. (73.2%). Coagulase negative staphylococci encompassing 68.3% of the isolates, whereas 4.9% was coagulase positive staphylococci. Bacillus spp. constituted 12.2% out of the isolates. Listeria spp. and Neisseria spp. both were represented 7.3%. There is a need to discuss the potential hazards of these bacteria in affecting milk quality, health of goats and food safety to consumers. The findings also emphasize the need to study the exact species of bacteria isolated in order to plan for their prevention as well as to assist veterinarians in prescribing correct antibiotic therapy
