“…E. coli is part of the normal intestinal flora in dogs and can also be isolated from the vagina in healthy female animals (Hirsh and Wieger ; Olson and Mather ; van Duijkeren ). Vaginal discharge (Bjurström ), faecal bacteria, bacteria of the oral cavity (Münnich and Lübke‐Becker ) and the contaminated environment are potential sources of infections in young dogs, similar to the situation in humans (Saizou et al. ).…”

Contents Neonatal diseases and losses are a common and often unavoidable problem within breeding kennels. Altogether, morbidity and mortality ranges, according to the literature, from 5 to 35%. Among non‐infectious causes besides hypoxia during birth, hypothermia, hypoglycaemia and dehydration are mostly responsible for puppy diseases and losses. Approximately 90% of all deaths in hypoxaemic pups occur during the first 2 days. Of 183 pups with hypoxia, 63 died, 92.7% of them within 48 h after birth. Among infectious causes, bacterial infection is the most common cause of neonatal mortality. Escherichia coli, streptococci, staphylococci, Pseudomonas sp., Klebsiella sp., Enterobacter sp. and some other micro‐organisms are regularly involved in neonatal infections. Post‐mortem findings especially document E. coli, Staphylococcus sp. and Streptococcus sp. as responsible bacteria. The dam and the environment are suspected as sources of neonatal infections as it was shown by genetic relatedness of responsible bacterial strains isolated in both puppies and their dams. From a total of 517 puppies with bacterial infections, the treatment results documented that parenteral administration of amoxicillin/clavulanic acid in 308 neonates showed the best result. Diagnosis of diseases is often made difficult by the absence of variability in clinical signs contrary to adult dogs. Findings during a physical examination in pups differ from those in adults. Furthermore, treatment recommendations have to meet the special conditions in neonates concerning drug metabolism and excretion.

“…Sanitary conditions and close monitoring of neonates are very important factors in the prophylactic management of the postpartum dam. Nosocomial infections or transmission of dog bacterial pathogens to owners have also been reported (Münnich and Lübke, 2004;Rota et al, 2011).…”

Data regarding bitch mastitis is fairly scarce compared to the literature regarding ruminant mastitis. Neglecting clinical and subclinical cases of mastitis can be life threatening for both dam and puppies. The aim of this report is to present a case of Mastitis acuta complicated with a case of neonatal septicaemia in a Cane Corso (Canis lupus familiaris L.) pure breed female. Laboratory assays showed a milk pH value of 7.5, milk cytology revealed the presence of segmented neutrophils, while foamy cells, phagocytosis and highly pathogenic bacteria (i.e. Escherichia coli and Pseudomonas aeruginosa) were isolated from milk and puppy. To the author's knowledge, this is the first case of bitch mastitis linked to neonatal septicaemia with mixed E. coli and P. aeruginosa infection.

“…However, information on sources of infections in newborn dogs is still limited. The environment and mothers are suspected as sources of infection (vaginal discharge, milk, faeces, oropharynx, skin) for puppies (Davidson, ; Münnich & Lübke‐Becker, ), similar to the situation in humans (Münnich, ). When puppies are exposed to bacteria and their defence mechanisms are overwhelmed, severe illness and newborn losses occur (Münnich, ).…”

The aim of the study was to identify beta-haemolytic streptococci in the vagina of bitches who had delivered healthy litters and bitches who had delivered litters in which neonatal deaths occurred. Fifty-one bitches divided into two groups were used. Group 1 (G1) included 28 bitches that had delivered healthy litters and group 2 (G2) included 23 bitches that had delivered puppies who died in the neonatal period. Two vaginal samples were taken, one in proestrus and the other at the end of gestation (EG). Beta-haemolytic Streptococcus (BS) was isolated from 16 bitches (57%) in G1 and from 21 bitches (91%) in G2. The bacteriological cultures, serological tests (Streptex ) and PCR assay allowed identification of Streptococcus canis and Streptococcus dysgalactiae in G1 and G2. Ultramicroscopic studies allowed the observation of M Protein and capsules in strains of S. dysgalactiae and S. canis in G1 and G2. The S. canis strains isolated from G2 showed thicker capsules than S. canis strains isolated from G1 (234 ± 24.2 vs 151.23 ± 28.93 nm; p < .001.). No differences were observed in capsule thickness between strains of S. dysgalactiae isolated from G1 and G2 (210 ± 13.54 vs 211.66 ± 19.67 nm; p > .70). All strains of beta-haemolytic Streptococcus isolated were penicillin sensitive. Penicillin was administered from EG to 5 days post-partum in 10 G2 females with isolation of BS (G2A). Saline solution was administered in eleven G2 females with isolation of BS (G2B). Ninety per cent of the puppies survived in G2A and 25% survived in G2B. Our results suggest BS is involved in canine neonatal deaths.
