CAUSING AGENT: Haemoproteus Columbae.

It has a definitive host, a hematograph fly (feeds on blood), pseudolynchia canariensis.

The intermediate host is the pigeon. It is necessary for the infested fly to bite the pigeon for the disease to develop in it.



Observable only in the summer months. The symptoms are very similar to those of plasmodiosis, hence the possible confusion (time and symptoms).

Flies that suck infected blood are capable of transmitting Haemoproteosis 15 days later and symptoms begin 25-30 days later:

  • Recurrent fever (up and down) 43 ºC.
  • Diarrhea: White or yellowish-white, liquid and persistent stools.
  • Dyspnea: increased respiratory rate.
  • Gradual anemia.
  • Cachexia: weight loss when the disease becomes chronic.

Form of DIAGNOSIS: Blood test (Giemsa method).

TREATMENT: Does not exist.

PROPHYLAXIS: Fight the Kaotrina type fly.
