Routine examinations of fecal samples from squirrel monkeys suggested that intestinal trichomonads might be common inhabitants of these animals. In pursuit of these observations, microscopic examination of fecal suspensions and cultures have demonstrated a 100% incidence of trichomonads in 30 arbitrarily selected animals from a colony of more than 300 housed in groups of ten. The most prominent species was Pentatrichomonas hominis. A not yet fully characterized tritrichomonad was also found on several occasions. The main obstacle in establishing individual strains in culture was the presence of bacterial and fungal flora in the samples. Nevertheless, abundant cultures were obtained from 28 animals by inoculation of fecal suspensions into tissue cultures with appropriately formulated medium and high concentration of antibiotics. In several unattended cultures maintained at room temperature, the flagellates retained motility for at least 4 months. This long survival may explain the widespread occurrence of the parasites within a confined animal community.
