MEETING OF OCTOBRE 27th 1983, ALFORT
The epidemiological approach followed by Montpellier university parasitologists is deeply coloured with ecology. In a first step, the author explains the rules of medical ecology through the relationship linking living organisms to their ecosystem. The second part applies this thinking to the study of leishmaniasis. Consequences are both theoretical and practical (what to do on the field and how to do it).

The authors show that Echinococcus multilocularis infection is a cyclo-zoonosis occurring over very different biotopes, from Alaska to Afghanistan, but always limited to the northern hemisphere. They recall the most important intermediate and final hosts of the parasite and the parameters acting over its cycle.They speak of the few accurate surveys undertaken to study the epidemiology of this disease; The recet discovery of human outbreaks, linked to the diagnosis of anilal outbreaks, leads to this question: Is E. multilocularis infection spreading?
Blancou (J) & Roboly (O)
Night shooting of wild stray animals, used in some countries, including France, is obviously of interest in epidemiology. On one hand, it allows an evaluation of the population density of animals living in the area where applied, and therefore measurement of the consequences of the disease, or of its control. On the other hand, it allows practice, on killed subjects, of representative analysis, in one animal species, of a specific disease, at a definite time.
The author presents the radio-tracking technique which allows the localisation at a distance of a wild animal bearing a radio-transmitter. Examples of fox rabies and badgers tuberculosis demonstrate the interest of this ethological method in the study of transmission factors of wild animal’s contagious diseases.
A list of the main parameters which characterize the poultry farming is presented. This list contains ten rubrics: "Environment", "Animals", "Farm-buildings", "Feed", "Watering", "Hygiene", "Systematic interventions", "Pathology", "Performances", "Previous analysis" .
