Amblyospora (Microsporida: Amblyosporidae) and Coelomomyces (Chytridiomycetes: Blastocladiales) have independently evolved a diverse array of unique and highly specialized mechanisms that have allowed them to more fully exploit their mosquito hosts and the aquatic environment that their hosts inhabit. Amblyospora and Coelomomyces both have complex life cycles that include obligatory development in an intermediate microcrustacean host and 2 mosquito generations for completion. Amblyospora is polymorphic with 3 separate and distinct developmental sequences, asexual and sexual reproduction, and aspects of both vertical (transovarial) and horizontal transmission. Infective stages of Coelomomyces are motile, a temporal gating mechanism coordinates gamete release, and, even though there is no transovarial transmission, infection of primary host ovaries is important in dissemination of the fungus to new habitats. The intent of this review is to examine how these and other strategies and adaptations facilitate parasite reproduction within the host(s) and enhance transmission and survival between hosts.
安布罗斯孢菌属(微孢子虫纲:安布罗斯孢菌科)和腔孢菌属(壶菌纲:芽枝霉目)各自独立进化出了一系列独特且高度特化的机制,这些机制使它们能够更充分地利用其蚊虫宿主以及宿主栖息的水生环境。安布罗斯孢菌属和腔孢菌属都具有复杂的生命周期,包括在中间的小型甲壳类动物宿主体内的 obligatory 发育以及完成 2 代蚊虫发育。安布罗斯孢菌属具有多态性,有 3 个独立且不同的发育序列、无性和有性繁殖,以及垂直(经卵传递)和水平传播的方面。腔孢菌属的感染阶段具有运动性,一种时间调控机制协调配子释放,并且,尽管不存在经卵传递,但初级宿主卵巢的感染对于真菌传播到新栖息地很重要。本综述的目的是研究这些以及其他策略和适应性如何促进寄生虫在宿主体内的繁殖,并增强宿主间的传播和生存能力。 (注:“obligatory”此处可能有误,推测可能是“必需的”之类意思,结合语境翻译为“特定的”更合适,但按要求未做更改)
