Perinatal lamb mortality in Western Australia
Infection was found in 14.5 percent of dead lambs classified as delayed or late post-parturient deaths or in 7.5 percent of the 4417 lambs autopsied. Eighteen species of bacteria were isolated from these acquired neonatal infections. Many infections resulted from umbilical contamination at birth, some by ingestion, some were superimposed complications upon an already existing condition such as starvation, others occurred as post-making sequellae. The microorganisms isolated were Clostridium septicum, C. pyogenes, Staphylococcus aureus, Pasteurella haemolytica, P. multocida, and Escherichia coli, F. necrophorum, Corynebacterium spp, C. perfringens, Streptococcus spp, A. lignieresii, Dermatophilus congolensis and miscellaneous species. It was estimated that acquired neonatal infections were responsible for one-thirteenth of the perinatal lamb deaths in the agricultural area of Western Australia or for approximately 1 percent of births
