Desciption

An infectious disease of the cat caused by Mycoplasma haemofelis which until recently was known as Haemobartonella felis. The organism is found on the surface of erythrocytes and is considered an opportunistic infection that causes illness under predisposing causes. It is possible to be transmitted via bite wounds or biting arthropods. Recoverd cats become carriers of the organism.

Signalment

Almost half of the cats infected have concurrent Feline Leukaemia VirusFeLV. Common in roaming Tom cats 1-3 years old.

Diagnosis

The organism is intermittently seen on the surface of red blood cells on Giemsa-stained blood smears.

  • Immunofluorescence of blood smears

When the organism is not found a presumptive diagnosis may be made with clinical signs of reduced packed cell volume, a regenerative anaemia.

Clinical signs

The peracute disease is associated with severe anaemia and immunosuppression, and can be rapidly fatal. Fever, anaemia, depression, weakness and jaundice occur in the acute form. In the chronic form animals present with anaemia, lethargy and weight loss. Recovery can occur with a regenerative bone marrow response however severe feline infectious anaemia may occur in the presence of feline leukaemia virus. (FeLV)


Treatment

  • Doxycycline for 3 weeks early in the course of the disease
  • Blood transfusion
  • Flea control

Prognosis
