The rate of perinatal death is variable but highest during parturition, immediately after birth and in the first days of life. Infectious diseases, above all bacterial, are the second most important cause of mortality after losses during parturition. A lot of factors are involved predisposing puppies and kittens to bacterial infections: respiratory distress, hypothermia, hypoglycaemia, dehydration, congenital abnormalities. E. coli, streptococci and staphylococci, Klebsiella sp., Pseudomonas sp., Enterobacter sp., Proteus sp. and anaerobes are regularly involved in bacterial infections in neonates. Postmortem findings especially document E. coli, Staphylococcus or Streptococcus species as causes of disease and death shortly after birth. The environment and mothers are suspected as sources of infection (vaginal discharge, milk, faeces, oropharynx, skin) for puppies and kittens. Genetic relatedness of bacterial strains in puppies and their mothers was found in staphylococci and E.coli. These results indicate that for repeated cases of bacterial infections in neonates diagnostic procedures of milk, vaginal and faecal swabs from bitches result in isolation of the responsible bacteria with a high probability and suggest that preterm treatment could help to control bacterial diseases and losses in pups.
