Abstract

Trypanosoma lucknowi n. sp. was isolated in culture from one of 126 Macaca mulatta originating from the vicinity of Lucknow, Uttar Pradesh, India. Trypanosoma lucknowi is distinctive because of the large number of epimastigotes and trypomastigotes which, in culture, exhibit no movement or only a slight bending of the flagellar end. This limited motility coincides with a free flagellum which is either completely absent or rudimentary. The microorganism is cloned readily, and the description is based upon such cultures. Trypanosoma lucknowi shows pronounced differences from other trypanosomes of South Asian macaques and from "aflagellar" African trypanosomes. The ultrastructural demonstration of a cytostome and contractile vacuole suggests ultimate grouping with stercorarian trypanosomes. A 3-D reconstruction of the flagellar pocket/cytostome region is included.

摘要

勒克瑙锥虫（Trypanosoma lucknowi）新种是从印度北方邦勒克瑙附近的126只猕猴中的一只体内通过培养分离出来的。勒克瑙锥虫具有独特性，因为在培养物中有大量的上鞭毛体和锥鞭毛体，它们在培养时没有运动，或者鞭毛末端只有轻微弯曲。这种有限的运动性与完全缺失或发育不全的游离鞭毛相一致。该微生物易于克隆，本描述基于此类培养物。勒克瑙锥虫与南亚猕猴的其他锥虫以及“无鞭毛”非洲锥虫存在明显差异。细胞口和收缩泡的超微结构显示表明其最终应归为粪源性锥虫类。文中还包含了鞭毛袋/细胞口区的三维重建图。
