The aim of this crosssectional study was to determine the proportion of animals with T. foetus infection among clinically healthy cats in Norway and to assess different risk factors for T. foetus infection such as age sex former history of gastrointestinal symptoms and concurrent infections with Giardia duodenalis and Cryptosporidium sp. Methods The sample population consisted of 52 cats participating in three cat shows in Norway in 2009. Samples were examined for motile T. foetus by microscopy after culturing and for T. foetus-DNA by species-specific nested PCR as well as for Giardia cysts and Cryptosporidium oocysts by immunofluorescent antibody test IFAT . Results By PCR T. foetus-DNA was demonstrated in the faeces of 11 21 of the 52 cats tested. DNA-sequencing of five positive samples yielded 100 identity with previous isolates of T. foetus from cats. Only one sample was positive for T. foetus by microscopy. By IFAT four samples were positive for Giardia cysts and one for Cryptosporidium oocysts none of which was co-infected with T. foetus. No significant associations were found between the presence of T. foetus and the various risk factors examined. Conclusions T. foetus was found to be a common parasite in clinically healthy cats in Norway. Background During the last decade the protozoan parasite Tritrichomonas foetus has been identified as an important cause of chronic large-bowel diarrhoea in cats especially among purebred cats in multi-cat households.
