Previous issue date: 2007-01-23 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Infection with gastrointestinal parasites in dogs can be associated with several factors. The
aim of this study was to identify these parasites and their frequencies, and to verify the factors
associated with infection. From November 2003 to September 2004 five-hundred dogs
presented to three veterinary establishments in the municipality of Rio de Janeiro were
evaluated. A form was filled for each dog, including information obtained from physical
examination and from the interview of the owner, approaching factors related to the dog, the
management and the owner. One fecal sample from each dog was examined by centrifugal
flotation and centrifugal sedimentation methods and stained by safranin-methylene blue
technique. Data obtained from physical exams and interviews, as well as the results of fecal
parasitological exams, were submitted to bivariate analysis and, after the selection of
significant variables (p=0.05), multivariate analysis was performed, using logistic regression.
Gastrointestinal parasites were detected in 46.4% of the dogs. Hookworms (15.2%), ascarids
(7.4%), whipworms (5.0%), Dipylidium caninum (0.2%), taeniids (3.0%), Cryptosporidium
sp. (26.2%), Cystoisospora sp. (4.4%) and Giardia sp. (2.6%) were observed in the fecal
samples. Protozoans (29.6%) were more frequently observed than helminths (23.2%). Age of
the animal (p<0.001), access to soil (p<0.001), ambient hygiene (p<0.01) and pro-oestrous
(p<0.05) were associated with infections with gastrointestinal parasites. Access to soil
(p<0.001), anthelmintic usage (p<0.01), owner s school level (p<0.01), age of the animal
(p<0.01), pro-oestrous (p<0.01) and breed (p<0.05) were associated with infections with
helminthes. Age of the animal (p<0.001) and ambient hygiene (p<0.01) were associated with
infections by protozoans. Frequency of gastrointestinal parasites in dogs was high and
infections were associated with factors related to the animal, to the management and to the
owner. / A infec??o de c?es por parasitos gastrintestinais pode estar associada a diversos fatores. O
objetivo deste estudo foi identificar tais parasitos, observar suas freq??ncias e verificar os
fatores associados ? infec??o pelos mesmos. De novembro de 2003 a setembro de 2004,
foram avaliados 500 c?es atendidos em tr?s estabelecimentos veterin?rios no Munic?pio do
Rio de Janeiro. Um formul?rio foi preenchido para cada c?o, atrav?s de exame f?sico do
animal e entrevista com o propriet?rio, abordando fatores inerentes aos c?es e fatores
relacionados ao manejo e ao propriet?rio. Uma amostra fecal de cada c?o foi coletada e
examinada pelas t?cnicas de centr?fugo-flutua??o em solu??o saturada de a??car e de
centr?fugo-sedimenta??o (Ritchie) e corada pela t?cnica de safranina-azul de metileno. Os
dados obtidos nos exames f?sicos e nas entrevistas, bem como os resultados dos exames
parasitol?gicos de fezes, foram submetidos ? an?lise bivariada e, ap?s sele??o das vari?veis
significativas (p=0,05), procedeu-se ? an?lise multivariada, atrav?s de regress?o log?stica.
Parasitos gastrintestinais foram detectados em 46,4% dos c?es. Nas amostras fecais
observaram-se ancilostom?deos (15,2%), ascarid?deos (7,4%), tricur?deos (5,0%), Dipylidium
caninum (0,2%), ten?deos (3,0%), Cryptosporidium sp. (26,2%), Cystoisospora sp. (4,4%) e
Giardia sp. (2,6%). Protozo?rios (29,6%) foram mais freq?entes do que helmintos (23,2%). A
idade do animal (p<0,001), o acesso ? terra (p<0,001), a higiene do ambiente (p<0,01) e o
pr?-estro (p<0,05) estiveram associados ? infec??o por parasitos gastrintestinais. O acesso ?
terra (p<0,001), a administra??o de anti-helm?nticos (p<0,01), o grau de escolaridade do
propriet?rio (p<0,01), a idade do animal (p<0,01), o pr?-estro (p<0,01) e a ra?a (p<0,05)
estiveram associados ? infec??o por helmintos. A idade do animal (p<0,001) e a higiene do
ambiente (p<0,01) estiveram associadas ? infec??o por protozo?rios. A freq??ncia de
parasitos gastrintestinais em c?es foi alta e as infec??es foram associadas a fatores inerentes
aos c?es e fatores relacionados ao manejo e ao propriet?rio.
