[A descriptive profile of the canine population in Araçatuba, São Paulo State, Brazil, from 1994 to 2004].
From 1994 to 2004, the canine population in Araçatuba, São Paulo State, Brazil, suffered two major canine zoonoses: rabies and visceral leishmaniasis. Changes in the dog population during this period were evaluated using canine census data from 1994 and 2004 and the results of blood samples for diagnosis of canine visceral leishmaniasis in 1999. The ratio of dogs per 10 inhabitants varied from 1.7 in 1994 to 2.0 in 1999 and 1.8 in 2004. The percentage of puppies less than 1 year of age increased from 20% to 32.5%, and the number of euthanized dogs also increased after 1999, when visceral leishmaniasis began to appear. The number of dogs and percentage of puppies varied between different areas of the city, and neighborhoods with a higher percentage of young animals showed more cases of both human and canine leishmaniasis. This result may be due to control measures applied in these areas in response to cases of human and canine visceral leishmaniasis, but the increase in the younger canine population can be accompanied by increased susceptibility in these animals, thus favoring maintenance of the disease in the area.
