Clinical responses of dogs to experimentally induced Dipetalonema reconditum infection.
Six male and 6 female Beagles, 6 to 7 months old, were allotted to 2 groups: group I--inoculated subcutaneously with 30 Dipetalonema reconditum infective larvae/dog, and group II--noninoculated controls. Group comparisons were made in regard to hematologic values, Knott test results, body weights, blood urea nitrogen, total serum protein, serum albumin and alanine aminotransferase and creatine kinase activities. Routine urinalysis data were compared at 1 week before and at 28 weeks after the inoculations. Mean total leukocyte counts were significantly (P less than 0.05) greater in group I dogs than in group II dogs at postinoculation weeks (PIW) 4, 5, and 7 to 12, and mean eosinophil counts were significantly greater in group I dogs at PIW 3 to 11, 13 to 15, 20, and 23 to 24. Microfilariae were detected as early as the 10th week and sporadically thereafter. Only 1 D reconditum adult worm was recovered from all of the inoculated dogs. Five other dogs (group III) with chronic, patient experimentally induced dipetalonemiasis, were evaluated with the same tests at PIW 70 to 89. Eosinophilia (greater than 750 cells/microliter) was present in 4 of 5 dogs; lymphocytosis (greater than 4,800 cells/microliter) was evident in 1 dog. Proteinuria (greater than or equal to 30 mg/dl) was detected in 3 of 4 dogs with chronic dipetalonemiasis.
