Abstract

Specimens for bacterial findings ; of 35 apparently healthy lambs taken from the respiratory tract were examined. Out of the total samples, 11 (31.43%) proved to be bacteriologically ste. rile. The flora of the normal samples inbluded : Stap < /em>h: epider. midis, B. mycoides, E. coli, Staph. aureus and Pasterurella multocida type 11.
Samples from 157 diseased lambs were classified according to the way of treatment. The most frequent micro-organisms isolated before treatment were Str. pyogenes, Str. alphahaemolytic, C. pyo genes, unclassified corynebacteria, Pseudomonas aeruginosa, E. coli, yeasts and moulds in their order of frequency.
The respond of the sick lambs to treatment was investigated. Sulphadimidine in combination with penicillin procaine ---G- and dihydrostreptomycin gave a better result than other methods of treatment.
