“…The fine structure of the undulating membrane in T. gollinae is similar to that figured previously for T. vaginalis (14,36,37,48,53). It is represented by a fin-like fold of the dorsal surface of the organism.…”

SYNOPSIS. The fine structure of Trichomonas gallinae has been examined by electron microscopy and correlated with previous light microscope observations. A composite diagram of the flagellate, derived from both types of examination, is presented. Details of relationships of various mastigont organelles are documented by electron micrographs. The extent of the pelta and its connection to the capitulum of the axostyle have been determined. Four types of kinetosome rootlets have been described. One consists of superficial “filaments” radiating from each of the 9 triplet microtubules of kinetosomes #1, #2 and #3. A 2nd type of rootlet structure is represented by single comma‐shaped filaments emerging clockwise from kinetosomes #1 and #3. The filament from kinetosome #1 has a periodic structure similar to that of the marginal lamella with which it is believed to connect. A 3rd type of rootlet emerges from kinetosome #2 as a sheet of about 9 filaments which traverse a sigmoid course and terminate on the inner surface of the microtubules of the pelta near the peltar‐axostylar junction. The 4th set of structures consists of the costa and parabasal filaments. These structures have major periodicities of similar dimension but have readily differentiable repeating units. The costa appears to originate at the kinetosome of the recurrent flagellum, but its origin is also contiguous with that of parabasal filament 2 which has some continuity with kinetosomes #2 and #3. Parabasal filament 1, on the other hand, arises solely from or near kinetosome #2. Occasional observations of a costa and a parabasal filament in juxtaposition over a great part of their length has led to the suggestion that the parabasal filament may play a role in the development of the costa. Periodic and filamentous structures have been observed in paraxostylar and paracostal granules and in nearby cytoplasm. Their possible role in providing substance for the developing axostyle and the costa is discussed. The results are discussed in the light of available information pertaining to structure of various trichomonad species as revealed by light and electron microscopy.

“…Panaitescu and others (1971) confirmed the observations of Perju and Petrea (1963) and Smith and Stewart (1966), who found three types of vesicles in trichomonads: vacuolated, replete, and containing filaments (lamellae). Figs 14-24 illustrate variations in morphology and the probable functional significance of vesicles.…”

“…The parabasal apparatus does not extend to the end of the body. Honigberg and King (1964) and Smith and Stewart (1966) claim that it is identical with the Golgi complex, but this opinion is incorrect. Figs 17 and 18 show that trichomonads have an independent and welldeveloped Golgi zone.…”
