[Spectrum of species and infection frequency of endoparasites in bitches and their puppies in south Germany].

Toxocara canis, Toxascaris leonina, hookworms, Trichuris vulpis, Strongyloides, Hammondia heydorni, Sarcocystis spp., Isospora canis and Isospora ohioensis and/or Isospora burrowsi of at least 9 species were detected in 100 randomly selected dog families in Southern Germany. Examinations carried out 5 to 9 times at weekly intervals revealed a monoinfection in 37 litters, infection with two parasite species in 28 litters, with three species in 10 litters and with four species in 6 litters. During the investigation period, 29 of the examined litters did not excrete helminth eggs, and, of these, 19 also did not excrete oocysts/sporocysts. In order of decreasing frequency among the dog families, the excretion extent of the litters and their mothers was as follows: Toxocara canis 67% and 45%, Isospora ohioensis/burrowsi 36% and 24%, Sarcocystis spp. 12% and 19%, Isospora canis 16% and 8%, Hammondia heydorni 7% and 6%, hookworms 6% and 7% and Toxascaris leonina 3% and 8%, respectively. Trichuris vulpis and Strongyloides eggs were only detected in 6 and 3 of the bitches, respectively.
