    Studies on mastitis in goats
    (Department of Medicine, College of Veterinary and Animal Sciences, Mannuthy, 1978) Venugopal, K; KAU; Paily, E P
    In the present investigation, milk samples from 56 clinical and 379 apparently normal goats were examined. Staphaurous was isolated from 52 percent of clinical cases. The other organisms isolated were, starph. Epidermidis, str, agalactiae, C.pyogenes, K.pneumoniae, Esch. Coli, Ent.aerogenes and P.aeruginosa. The samples examined from apparently normal goats revealed an incidence of 47 percent subclinical mastitis. Mastaid Test conducted on milk samples from apparently normal goats revealed that this test was 96.5 percent efficient in detecting subclinical mastitis. From the somatic cell counts performed on milk samples, it was observed that normal milk (CMT Zero) had a mean cell count of 0.9 lakhs per ml. The cell counts of 5 to 10 lakhs (CMT + ) represented subclinical mastitis. When a comparative study was conducted study was conducted with mastrid test, whiteside test and tcepol mastitic test it was observed that mastaid reagent could only be relied upon in detecting subclinical mastitis. Chloramphenicol was found to be the drug of choice in goat mastitis, as evidenced by the in vitro sensitivity tests. Erythromycin, Ampicillin, Terramycin and Pencillin were moderately efficient. Results of the treatment with sensitive drugs on 40 selected clinical cases have been discussed.

    Study on the incidence of brucellosis in buffaloes in Trichur
    (Department of Preventive Medicine, College of Veterinary and Animal Sciences, Mannuthy, 1978) Baby, K; KAU; Paily, E P
    The result of an investigation, carried out on 1026 buffaloes in and around Trichur, to assess the incidence of brucellosis in buffaloes was recorded. Standard serum tube agglutination test was carried out on the blood samples collected from 590 animals in and around Trichur, 146 animals maintained in the three organised farms in the State and 290 animals slaughtered at the abattoir, Kuriachira, Trichur. Milk ring test was conducted on 115 individual samples of milk. The overall incidence of brucellosis in the buffalo population tested was 2.24 per cent. All the animals maintained in the organised farms gave a negative result to brucellosis. The possible methods of control and eradication of brucellosis in Kerala State were discussed.
