OBJECTIVE
The objective was to study the effect of Bauhinia variegata L. stem bark powder as adjunct therapy in chronic Staphylococcus aureus mastitis in goat.
METHODS
Mastitis was induced by intracisternal inoculation of coagulase positive S. aureus (J638) at the concentration of 2000 colony forming units. Group I animals were treated with repeated dose of ceftriaxone at 20 mg/kg intravenously, and Group II animals were treated with once daily oral administration of B. variegata L. stem bark powder at 6 g/kg for 7 days followed by maintenance dose at 3 g/kg for next 7 days along with repeated dose of the antibiotic at 20 mg/kg intravenously at 4 days interval.
RESULTS
No significant improvement in the clinical condition of the udder was noticed in the group treated with repeated dose of ceftriaxone alone. However, in the group treated with B. variegata L. stem bark powder along with repeated dose of ceftriaxone, no S. aureus colony was seen at 96 h and onwards in milk samples with a marked decrease in somatic cell count and milk alkaline phosphatase activity and increased lactoperoxidase activity. Further, plasma and milk concentration of ceftriaxone/ceftizoxime was increased, which indicated antibacterial, bioenhancing and antiinflammatory properties of the bark powder. The Group II animals also exhibited marked reduction in polymorphonuclear cells and fibrous tissue indicating antifibrotic property of B. variegata L.
CONCLUSIONS
B. variegata L. stem bark powder can be considered as an effective adjunct therapy to intravenous ceftriaxone in S. aureus chronic mastitis in goat.
