ZOONOSES Symptoms and Treatment


THE PIGEON / MAN ZOONOSES

THE PIGEON / MAN ZOONOSES
CHLAMYDIOSIS (ORNITHOSE-PSITTACOSIS)
Infectious and contagious disease caused by a bacterium (chlamydia psittacid). This disease affected in 1990 about 50% of Parisian pigeons. In Toulouse, in 1982, a survey revealed an infection rate of 45% of the Colombian population. In humans, ornithosis is now rare and most often transmitted by exotic birds or backyard birds. Sources of contagion are sick animals, cures, healthy carriers, and secretions and excretions.

The man can thus contaminate himself by inhalation of wing scales, by the droppings, the dust or the soiled material.

Clinical symptoms in pigeon: conjunctivitis, rhinitis, respiratory disorders, anorexia, delayed spawning. Significant mortality among young people.

Clinical symptoms in humans: flu-like syndrome. The acute form can cause atypical pneumonia.


Treatment ZOONOSES

Treatment ZOONOSES : tetracyclines, macrolides, antibiotics. It should be noted that the pigeon remains a chronic carrier.

Prophylaxis: Eradication or even prevention is difficult because of the very wide spread of the disease. The ideal solution would be the elimination of the patients, the treatment of the colony, the disinfection of the nesting sites, and the premises and equipment (for the farms).

The dovecote will reduce the health risk because it allows to monitor the general condition of the colony.

SALMONELLOSIS
Disease caused by a bacterium and worldwide widespread. It affects many animal species. The risk of transmission of salmonellosis to humans by the urban pigeon is reduced. Symptoms: in the pigeon, poor general condition, slimming, arthritis of the wing, diarrhea …

In humans, gastroenteritis. The patient remains a carrier for several weeks.

Treatment: anti-infectives, antibiotics.

Prophylaxis: Offensive: elimination of contaminated animals. Defensive: regular cleaning of nesting sites and equipment (dovecotes).

CRYPTOCOCCOSIS
Opportunistic mycosis. Various studies in different parts of the planet, have revealed a high risk for humans.

Symptoms: no pathology in the pigeon, but serious pulmonary involvement has been observed in immunocompromised human subjects. However the risk of contamination of people in good general health is low.

NEWCASTLE’S DISEASE
Caused by a virus (plague or bird flu). The contamination between birds is by respiratory, digestive.

Symptoms: in the pigeon the disease takes the form of respiratory and nervous pathologies. Mortality is high. In humans, the disease takes the form of a flu-like state.
