Bacterial diseases in Cats

Bacterial diseases affect all animals and cats are no less immune or unique to their onslaught. They can cause varying ranges of illness in cats from mild dermatitis to sepsis and death. Appropriate antimicrobial therapy should be based on isolation and culture and sensitivity of causative bacteria.

Common bacterial diseases in cats include:

  • Actinobacillus spp – gingivitis and respiratory infections
  • Actinomyces spp – systemic infections
  • Anaerobiospirillum spp – enterocolitis
  • Anaplasma spp – tick-borne anaplasmosis
  • Bacteroides spp – abscesses
  • Bartonella henselae – cat scratch disease
  • Bordetella bronchiseptica – respiratory disease (kennel cough)
  • Borrelia burgdorferi and other spp – Lyme disease and possibly associated with lymphoma in cats
  • Burkholderia pseudomellei – ocular and pulmonary bacteria causing feline melioidosis in tropical regions
  • Campylobacter spp – secondary diarrhoea
  • Chlamydophila felis – conjunctivitis and rarely, respiratory disease
  • Citrobacter spp – vaginitis, salpingitis
  • Clostridium spp – diarrhoea, tetanus
  • Corynebacterium spp – cellulitis, FLUTD
  • Coxiella burnetti – Q fever
  • E. coli – food spoilage diarrhoea
  • Ehrlichia spp – tick-borne ehrlichiosis
  • Francisella tularensis – tularemia
  • Fusobacterium spp – normal oral flora but can cause cellulitis and pyothorax
  • Haemophilus spp – rhinitis, bronchial disease
  • Haemoplasmas
