Pathogenic trichomonads in cats and dogs
Vobořilová, Pavlína ; Tachezy, Jan (advisor) ; Hampl, Vladimír (referee)
Trichomonads are anaerobic flagellated protists that are either parasites or commensals. They frequently inhabit digestive, respiratory, and urogenital tracts of vertebrates, including domestic cats and dogs. In these hosts, four trichomonad species has been described: Tetratrichomonas canistomae and Tetratrichomonas felistomae that are commensals of the host oral cavity; Pentatrichomonas hominis, a commensal of intestinal tract that could be found in dogs and cats but also in other mammals including humans; and pathogenic Tritrichomonas foetus that causes, in addition to cattle infection, feline intestinal trichomonosis. Although, trichomonads in dogs and cats are probably of cosmopolitan distribution we have no information about their presence in Czech Republic. The first aim of this study was to distinguish types of trichomonads present in the oral cavity of dogs and cats and to get preliminary epidemiological data. The second aim was to demonstrate the presence of Tritrichomonas foetus in cats and dogs in the Czech Republic and to identify potential risk factors for the disease. Cultivation and nested PCR were used to determine the presence of trichomonads in dogs and cats. Sequencing and phylogenetic analysis based on ITS1-5.8rRNA-ITS2 gene sequence was used to identify species of isolated...

Pathogenic trichomonads in domestic animals
Vobořilová, Pavlína ; Tachezy, Jan (advisor) ; Čepička, Ivan (referee)
Pathogenic trichomonads of domestic animals are anaerobic protozoa found in the gastrointestinal and reproductive tract. They are responsible for serious diseases, which result in economic losses in agriculture. Cochlosoma anatis parasitizes in the intestine of birds, where it causes so-called runting syndrome and enteritis. Trichomonas gallinae is found in the gastrointestinal tract of pigeons and represents a dangerous infection of wild migratory birds and endangered birds of prey. Histomonas meleagridis is the causative agent of the best known, fatal and very redoubtable disease of turkeys and hens, so-called "blackhead disease". Tritrichomonas foetus is the causative agent of the most important sexually transmitted infection, tritrichomonosis in cattle, which causes significant economic losses in global beef production. T. foetus was recently identified as the causal agent of diarrheal disease in cats. Also Tritrichomonas mobilensis was recently described as a new species which probably disrupts the intestinal mucosa of squirrel monkeys. This work includes the general characteristics of these species and a detailed summary of the current knowledge on the diseases they are causing. The description covers the issue of sources and disease transmission, host specificity of the parasite and...
