Rearing of indigenous Tharparkar (TP) cows (native of arid Thar deserts) under high humid conditions (>75% humidity) has increased the incidence of mammary infections in them. A study was undertaken to see the number, activity, and expression of milk neutrophils isolated from healthy and mastitic cows. There was a significant (P< 0.05) influx in milk somatic cell counts (SCC) and neutrophils in sub-clinical and clinical mastitis cows. No change was observed in the phagocytic activity (PA) of milk neutrophils between healthy and sub-clinical mastitis (SCM) cows, but these activities decreased significantly (P< 0.05) in clinical cases. Chemotactic activity showed a significant difference between all the groups. Lactose varied significantly (P < 0.05) between healthy, sub-clinical, and clinical mastitis (CM) cows. Expression of chemokine receptor (CXCR1) was more in mastitis cows and also higher as compared to CXCR2. No change was observed in cluster of differentiation molecule (CD62L) among all the three groups of TP cows. Expression of interleukin (IL-8) and CD11b was low in healthy cows, increased significantly (P< 0.05) in both sub-clinical and mastitis cows. This study indicates that low producing TP cows are also prone to mammary infections when reared under semi-arid conditions. Not Available |
