Occurrence of Tetratrichomonas gallinarum (Trichomonadida: Trichomonadidae) in chicken feces from Lorestan Province, Western Iran

AbstractSpecies ofTetratrichomonas gallinarum andTrichomonas gallinae, are found in the digestive tract of birds. To investigate trichomonads of a lower intestinal tract of native chickens, we examined 72 feces samples from the different life stages of fowl species in Khorramabad County, Lorestan Province, Western Iran. Using microscopical examination, out of 72 collected samples, 26 (31.6%) bird feces samples were found infected with a trichomonad similar toT. gallinarum. A 527-bp fragment of 18S rRNA gene ofT. gallinarum was amplified by PCR. The 18S constructed phylogeny indicates two different clades withinT. gallinarum, suggesting that commensalT. gallinarum-like of the bird hosts may be the reason for the genetic divergence inT. gallinarum species complex.
