Introduction

Four species of the family Trichomonadidae are found in humans, Trichomonas vaginalis (Donne, 1836), Trichomonas tenax (O.F. Muller, 1773), Pentatrichomonas hominis (Davaine, 1860), and Trichomitus fecalis (Cleveland, 1928). Although there have been many nomenclature problems with Pentatrichomonas hominis (Davaine, 1860), it is clear that this parasite represents another genera of the family Trichomonadidae.[1,2]

The most widely and best studied parasite is T. vaginalis, the urogenital trichomonad, which occurs almost exclusively in the lower genital tract. Trichomonas vaginalis is considered the only typical trichomonad with definite pathogenicity for humans.

Trichomonas tenax is considered a normal commensal of the human oral cavity. It is found especially in the tartar around the teeth or in the defects of carious teeth; although there is no evidence of direct pathogenesis, it is frequently associated with phylogenic organisms in pus pockets or at the base of teeth and its incidence is higher among patients with periodontal disease.[3]

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
