title: Relationship of toxoplasma infections to other diseases in dogs.
abstract: Toxoplasma infection as detected by the immunofluorescent antibody (IFA) test was found in 13.2% of 448 dogs examined at the Purdue University Small Animal Clinic. Only titres of 1/64 and above were considered positive, but lesser titers were encountered more frequently. The highest titer observed was 1/1024 in 2 dogs one of which had idiopathic epilepsy and the other had dirofilariasis as well as hip dysplasia. The incidence of positive sera from male and female dogs were 11.7 and 14.5%, respectively. The highest frequency of infection occurred in young dogs up to 4 years of age and the lowest was in older animals. The presence of the high toxoplasmosis IFA titers in the sera of dogs seems to be associated with other disease conditions. Stress such as joint dislocations, fractures, helminth parasitism, and concomitant bacterial and viral infections, etc., was observed in 62.7% of the positive cases. Presence of tumors and renal disease conditions were associated with 28.8 and 5.2%, respectively, of the positive sera.
