Page 348, 2. Materials and methods, 2.1. Animals and methods, Lines 12–16: Enrolled dogs were treated with doxycycline (Ronaxan1, Merial) at 10 mg/kg daily for 30 days and with ivermectin–pyrantel pamoate (Cardotek Plus1, Merial) at a minimum dose of 6 μg/kg of ivermectin + 5 mg/kg of pyrantel once every 15 days for 6 months. “
“Tritrichomonas mobilensis is a common intestinal trichomonad of squirrel monkeys, such as Saimiri spp., which have been used in biomedical research ( Pindak

et al., 1985 and Culberson et al., 1986). The role of this parasite in gastrointestinal pathology of monkeys has not been well established. It has been demonstrated that T. mobilensis is invasive in natural hosts ( Scimeca et al., 1989) as well as in experimental animals ( Culberson et al., 1988); however, inflammatory check details response in the natural host of this parasite has not been observed. Newborn squirrel monkeys are free of this parasite but acquire it at 1–2 months of age either from their mothers or from cage mates ( Brady et al., 1988). Sampling of a large number of adults failed to identify trichomonad-free individuals during suggesting that squirrel monkeys may be life-long carriers of T. mobilensis ( Pindak et al., 1988). Tritrichomonas foetus is the causative agent of cattle trichomonosis, which is one of the most prevalent sexually transmitted disease in cattle. In cows, the infection varies from a mild vaginitis or cervicitis, to endometritis, abortion and infertility. Significant losses may occur because of infertility and abortion ( BonDurant, 2005). T. foetus is currently recognized as the agent of feline trichomonosis, which is a large bowel disease in domestic cats ( Tolbert

and Gookin, 2009). In literature from the 1990s and even more recently, a hypothesis has been raised suggesting that T. mobilensis, T. foetus and Tritrichomonas suis (a gastrointestinal commensal of pigs) are the same species ( Felleisen, 1997 and Kleina et al., 2004). These groups analyzed both the internal transcribed space (ITS) regions and 5.8S rRNA genes, and they claimed that T. foetus and T. suis had identical sequences and that only one substitution was found in the ITS2 region of T. mobilensis. However, Felleisen (1998) tested the randomly amplified polymorphic DNA from the same three species and reported that T. mobilensis was genetically distinct from the other tritrichomonads. Recently, further structural and molecular studies confirmed that T. foetus and T.
