The role of corynebacteria in perinatal lamb mortality.
Among five species from 44 cases of neonatal mortality in lambs, four were C. pyogenes, C. pseudotuberculosis, C. renale and C. equi; 13 strains were unidentified diphtheroids and were regarded as being "intermediate" species. The importance of these unidentified diphtheroids is not known. The corynebacteria were responsible for abortion, navel-ill, pyaemia, pneumonia, pericarditis, meningitis, cerebral abscess, hepatitis and were suspected as a cause of neonatal mortality in lambs.
