To the Editor: Pasteurella multocida is an oral commensal of domestic pets known to be an opportunistic human pathogen after traumatic animal contact. The most common infections in humans are skin and pulmonary infections. This report outlines a case of P. multocida meningitis, which has not previously been reported in Australia.
A 19-day-old girl presented with a 12-hour history of fever and poor feeding. Her temperature was 39.5°C, and she was irritable, with no localising signs or skin lesions. A full septic screen was performed. Cerebrospinal fluid (CSF) showed a neutrophilic pleocytosis and gram-negative coccobacilli. She was treated with intravenous cefotaxime and gentamicin. Within 24 hours both CSF and blood cultures showed growth of gram-negative bacilli. The initial Gram stain, growth on chocolate agar and positive oxidase and catalase tests were suggestive of a Haemophilus species. However, further biochemical tests revealed the organism to be P. multocida. The infant made an excellent clinical recovery, with normal neurological and growth assessments at 6 and 12 months.
The family owned two cats but reported no contact between their baby and the pets. A single tonsillar swab performed on each cat by a veterinarian 10 days after the baby’s presentation failed to isolate Pasteurella species. The family elected to keep the pets.
Pasteurella meningitis occurs at extremes of age, in the immunocompromised (associated with liver cirrhosis, renal disease and haematological malignancies) and after traumatic head injury.1 Infants aged under 1 year account for almost half the cases of P. multocida meningitis.
On review of the literature, we found 37 reported cases of P. multocida infection in infants (Box).1-5 In more than three-quarters of these cases, there was known contact with household animals — in more than half of these contact was non-traumatic (licking or presumed handling of the pet). Molecular studies in one of the cases with no history of traumatic contact confirmed that P. multocida isolates from pet and infected child were indistinguishable.2
This infection is unusual, and, given the popularity of household pets, the risk appears low. However, this case highlights the relative immunocompromise of newborn infants, and is a reminder of the importance of hand hygiene and preventing contact between newborn infants and pets.
