Trichomonosis in dromedary bulls

During a routine health check of 12 breeding dromedary bulls using microscopy two of them were found to harbour trichomonad flagellates in their preputial washings. A PCR conducted on one of the samples did confirm trichomonads but not Tritrichomonas foetus. DNA sequencing identified the organism as Tetratrichomonas species. After repeated careful washings of the prepuce with oxidised water resampling revealed negative results.
