Intestinal infection of pigs with trichomonads, (Tritrichomonas suis, Tetratrichomonas buttreyi, and Pentatrichomonas hominis) has been reported in many countries, such as the Philippines, Belgium, and the Czech Republic. However, the prevalence of trichomonads infection of swine in China has not yet been investigated. In this study, we used small subunit ribosomal RNA genes to detect the prevalence of T. suis, T. buttreyi and P. hominis among 158 fecal specimens from healthy pigs. Infection rates were 12.03%(19/158), 14.57% (23/158), and 24.05% (38/158) for T. suis, T. buttreyi and P. hominis, respectively. Molecular evolutionary analysis showed minor allelic variation in T. buttreyi from China compared to T. buttreyi isolated from other hosts in different parts of the world.

Background: In pigs, several different trichomonad species such as , and have been described as inhabiting the digestive tract. However, little information is available on the epidemiology of these neglected parasites in the Chinese pig population.
Methods: The prevalence of , and among 500 fecal specimens from pigs at seven pigs farms in Anhui Province in China between Oct and Dec 2014, was determined by PCR and DNA sequence analysis of the small subunit ribosomal RNA (SSU rRNA) genes.

Trichomonads found in pigs include the commensal Tritrichomonas suis (more well known because of its synonymy to Tritrichomonas foetus, a trichomonad parasite of cattle and other animals) and Tetratrichomonas buttreyi, which appear similar to Tritrichomonas suis under the light microscope. A trichomonad isolated from pig fecal samples was subjected to scanning and transmission electron microscopy for ultrastructural study. The organism's ultrastructure revealed features commonly found in trichomonads; however, features such as the number and length of flagella, type of undulating membrane, general body form, and shape and location of organelles such as the nucleus, Golgi complex, and hydrogenosomes indicated that the isolated trichomonad is not Tritrichomonas suis nor Tritrichomonas foetus.
