PREVALENCE OF ENDOPARASITES IN DOGS FROM THE URBAN AREA OF MONTE NEGRO MUNICIPALITY, RONDÔNIA, BRAZIL

ABSTRACT

From July to August 2001, individual fecal samples were collected from 95 dogs (13.8% of the canine population) living in the urban area of Monte Negro, Rondônia. The fecal samples were processed by the following coproparasitological methods: Willis (simple flotation), centrifugal flotation employing sacarose solution, and centrifugal sedimentation employing water-ether. Only 15 (15.8%) out of 95 fecal samples were negative. Five helminth genera were found: Ancylostoma, Toxocara, Trichuris, Spirocerca, Physaloptera; as well as 5 protozoan genera: Sarcocystis, Giardia, Cystoisospora, Cryptosporidium, Hammondia-Neospora. Ancylostoma spp. eggs were the most prevalent (73.6% of positive samples), followed by Toxocara canis eggs (18.9%) and Sarcocystis spp. sporocysts (18.9%). Prevalence of the remaining parasites was less than 10%. The results were compared with other Brazilian studies, showing that the genus Ancylostoma is the most frequently found on dogs in Brazil.
