Studies on the biology of 4 Trypanosomes of Estrildidae birds described in a previous paper (Chandenier et al., 1988) are related. In Culicoides nubeculosus, the complete development is achieved in 7 days. After a phase of intense multiplication of amastigotes in the gut, infective trypomastigotes appear. In cultures, infective stages are obtained in 13 days. Transmission to clean birds was attempted: in two out of 8 attempts, a satisfactory level of parasitaemia is obtained. Surprisingly Trypanosomes infecting the new birds are unable to develop further in cultures or in Culicoides. The most likely hypothesis is the lack of a factor allowing the Trypanosomes to mature.
此前一篇论文（尚德尼耶等人，1988年）中描述的关于梅花雀科鸟类的4种锥虫生物学的研究具有相关性。在库蠓中，整个发育过程在7天内完成。在肠道内无鞭毛体大量增殖阶段之后，感染性锥鞭毛体出现。在培养物中，13天可获得感染阶段。尝试将其传播给未感染的鸟类：在8次尝试中有2次获得了令人满意的寄生虫血症水平。令人惊讶的是，感染新鸟类的锥虫在培养物或库蠓中无法进一步发育。最有可能的假设是缺乏使锥虫成熟的因子。
