Abstract

The occult dirofilariasis is considered a great diagnostic problem and may be related to: a) pre-patent infections; b) infections caused by worms of one only sex; c) parasites sterility due to the age or induced by drugs action; d) iirmune mediate response. The present study estimated the prevalence of the dirofilariasis in dogs in São Paulo State by means R TM of the ELISA test (CITER Semi-Quant TM Canine Heartworm Antigen Test Kit) as well as it tried to caracterize the cause of the circulating microfilaraemia absence using subsidiary exams. From 244 examined sera, 35 (14.34%) showed to be positive. From these, 20 presented one or more alternations (radiographic/ haematologic/eletrocardiographic), besides the positive ELISA test, which were compatible with dirofilariasis diagnosis. In the 15 animals left, which were assintomatic and seropositive by means of the ELISA test, no pre-patent infection was possible in spite of being to the infection risk for 6 months. Also the parasite sterility in consequence to drugs action was no observed
