Effects of Mycoplasma spp, Trichomonas fetus, and Campylobacter fetus on ciliary activity of bovine uterine tube organ cultures.

Microscopic observations were made of sections of normal bovine uterine tube (oviduct) and fimbriae maintained in vitro and exposed to agents known to localize in the bovine genital tract, i.e., mycoplasma, Trichomonas fetus, and Campylobacter fetus (Vibrio fetus). Only C fetus stopped ciliary activity. Scanning electron microscopy (SEM) revealed loss of most cilia. Sterile filtrate of C fetus culture had no effect.
