ABSTRACT: The results of coproscopical examinations in horses, ruminants, pigs, dogs, cats, hedgehogs and rabbits between 1998 and 2002 are presented. In 4399 samples from horses 37.4% stages of strongylids, 1.4% anoplocephalids, 1.3% Strongyloides westeri, 0.9% Parascaris equorum, 0.04% Oxyuris equi, 0.04% Eimeria sp. and 0.04% Fasciola hepatica were found. In 998 samples of cattle 22.1% stages of strongylids, 11.2% of Eimeria spp., 3.5% of cryptosporidium, 2.9% of Moniezia spp., 1.3% of Trichuris spp., 0.7% of Dictyocaulus sp., 0.6% of Fasciola hepatica, 0.6% of Strongyloides sp., 0.5% of Nematodirus spp. and 0.4% of Capillaria sp. could be detected. In 524 samples of sheep 60.7% eggs of strongylids, 43.1% oozysts of Eimeria spp., 11.1% stages of Nematodirus spp., 9.5% of Moniezia spp., 7.8% of Trichuris spp., 6.7% of Strongyloides sp., 1.7% of Fasciola hepatica, 1% of Capillaria spp., 0.4% of protostrongylidae, 0.2% of Skrjabinema sp. and 0.2% of Dictyocaulus sp. were found. 33.9% of the 118 samples of goats that were examined were positive for oocysts of Eimeria spp., 30.5% for eggs of strongylids, 6.8% for Nematodirus spp., 4.2% for Trichuris spp., 3.4% for Moniezia spp., 0.8 for protostrongylids and 0.8% for Strongyloides sp. 5.7% of 1427 samples of pigs contained stages of strongylids, 1.5% of Ascaris suum, 0.4% of Isospora, 0.3% of Eimeria spp., 0.3% of Trichuris sp., 0.1% of Giardia sp., 0.1% of cryptosproidium as well as 0.1% of metastrongylids. In 1281 of the samples of dogs 2.3% Giardia sp., 2.3% Isospora sp., 2.2% Toxocara canis, 1.4% ancylostomids, 0.8% taeniids, 0.6% larvae of Crenosoma sp., 0.2% Capillaria sp, 0.2% Trichuris vulpis and 0.2% Hammondia-like oocysts were found. In 441 samples of cats 10.7% stages of Isospora sp., 3.9% eggs of Toxocara cati, 1.6% of ancylostomids, 1.4% of taeniids, 1.1% of Giardia sp., 0.7% of Toxoplasma-like oocysts, 0.7% of Aelurostrongylus abstrusus, 0.5% of Toxascaris leonina and 0.2% of Capillaria spp. were found. Furthermore 0.2% of the samples contained proglottids of Mesocestoides and 0.2% stages of Dipylidium sp. Eggs of Capillaria sp. were found in 33% of the 106 samples of hedgehogs, larvae of Crenosoma striatum in 27.4%, oocysts of Isospora sp. in 5.7% of the cases. In 232 samples of rabbits 56.9% oocysts of Eimeria sp., 4.8% stages of Passalurus ambiguus, 1.3% of strongylids, 0.9% of Strongyloides sp., 0.4% of trematodes were found.

ABSTRACT: In eight cats and their offspring the mode of transmission of Toxocara cati following natural and experimental infection was investigated in three experiments. In experiments 1 and 2 the kittens of four cats with a chronic natural infection and of four cats with an acute experimental infection, respectively, were examined. In experiment 3 two queens of experiment 2 were mated again to examine whether in the adult cat "dormant" larvae exist in the tissue, that can be reactivated during pregnancy or lactation to infect the offspring. Additionally, the muscle tissue and organs of two adult cats, one with chronic one with acute infection, were examined for hypobiotic larvae. Pre-natal infections with T. cati did not occur in experiments 1 or 2. In none of the kittens that were examined directly after birth were larvae found. In the offspring of experiment 1 one single larva of T. cati was found 28 days post-partum. Whereas in the kittens of experiment 2 up to 333 larvae were found in one animal. Lactogenic transmission of larvae occurs after acute infection of the queen during late pregnancy but not during chronic natural infection. There is no evidence for the existence of arrested somatic larvae in the adult cat as an important host-finding strategy in the life cycle of T. cati. Following milk-borne infections, the majority of larvae seem to undergo direct development in the intestine without tracheal migration. Only a small number of larvae was found in other organs.
