Al-Dujaily AH, Al-Alo KZK, Mohmoud MHS., Hematology, bacteriology and antibiotic resistance in milk of water buffalo with subclinical mastitis, Onl J Vet Res., 23 (1): 1-8, 2019. Authors report hematology, bacteriology and antibiotic sensitivity in milk from 43 water buffalo with subclinical mastitis compared with 60 healthy controls. Blood was taken for hematology and biochemistry, and milk for California mastitis, culture and antibiotic sensitivity tests. We detected S aureus in milk of 72% of buffalo with mastitis. Compared with controls, red blood cell count was 26%, hemoglobin 14% and packed cell volume 10% lower (P < 0.05) in buffalo with mastitis. White blood cell counts were 20% greater (P< 0.05) in those with mastitis but there were no differences with mean corpuscular volume or mean corpuscular hemoglobin concentration compared with controls. In cows with mastitis, total serum protein was 20%, alanine 29%, aspartate transaminase 24%, alanine phosphatase 36% and lactate dehydrogenase 38% higher (P < 0.05), compared with controls. S. Aureus were 100% sensitive to vancomycin 87% to ciprofloxacin, but resistant to penicillin (100%) and erythromycin (77%).
