The aim of this study was to evaluate the susceptibility of dogs to develop paracoccidioidomycosis by experimental infection. Puppies were inoculated with Paracoccidioides brasiliensis by an intravenous route and two out of four died 1 week postinoculation, showing, at histopathological analysis, granulomas in the lungs, spleen and liver. P. brasiliensis was isolated from these organs. The animals that survived the infection showed a strong reaction when skin was tested with gp43, a specific antigen of P. brasiliensis. These animals were killed at 1 and 5 months after infection, and no lesions, macroscopic or microscopic, were observed in the lungs, spleen or liver; furthermore no P. brasiliensis culture was obtained from these organs. These results suggest that dogs can develop paracoccidioidomycosis and reinforces the importance of this animal as a sensitive indicator of P. brasiliensis in the environment.

D004285 Dogs The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065) Canis familiaris,Dog
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
