During the investigation “Cultural studies of clinical mastitis in goats’’ was under taken to study the diagnostic approach of clinical mastitis in goats based on cultural examination. Out of 260 quarters of 130 goats screened for clinical mastitis (CM), 54 quarters of 33 goats were found positive for clinical mastitis based on bacterial culture examination. The following bacteria were isolated from clinical mastitis affected milk samples as single infection which included coagulase negative Staphylococcus spp., Escherichiacoli spp., Klebsiellaspp., Streptococcus spp. and coagulase positive Staphylococcus spp., were identified in 29.63,20.37,11.11, 9.26 and7.41percent. In mixed infection, the bacteria identified were coagulase negative Staphylococcus spp. in along with Escherichia coli, Coagulase negative Staphylococcus spp with Klebsiella spp., E. coli with Streptococcus spp., Coagulase negative Staphylococcus spp. with Streptococcus spp. and coagulase positive Staphylococcus spp., with Escherichia coli 7.41, 5.56, 3.70, 3.70 and 1.85 percent respectively. The drug sensitivity patterns of the above bacterial isolates revealed that, organisms were highly susceptible to Cefoperazone and Ceftriaxone followed by Amoxyclavacid (85%), Enrofloxacin (70%), Gentamicin (60%), Doxycycline (45%) and Ampicillin (35%). While, all the bacterial isolates (100%) whole milk cultures were resistant to penicillin G.
