Morphological evidence of a filamentous cilia-associated respiratory (CAR) bacillus in goats.

A filamentous cilia-associated respiratory (CAR) bacillus was discovered in 12 3-4 month-old goats experimentally infected with two different strains of mycoplasmas belonging to the Mycoplasma mycoides type. The CAR bacilli were always arranged parallel to the cilia, and the morphology of these bacilli is very similar to that of other bacilli described previously in other species from various parts of the world.
