1887

Abstract

A parasite of the cladoceran Leydig 1860 found near Beltsville, Md. and designated CPB was successfully propagated for morphological and ultrastructural studies by infecting laboratory-reared hosts. An ultrastructural examination of vegetative cells indicated that the parasite was procaryotic. The morphology of CPB was nearly identical to that of Metchnikoff 1888. Consequently, CPB was considered to be an organism like . An electron microscopic study of CPB provided no evidence of longitudinal fission, a concept which had been proposed for by Metchnikoff, but supported much of Metchnikoff's original description for . For example, CPB was a parasite of a cladoceran. Primary colonies were cauliflower-like. Daughter colonies were formed by fragmentation of mother colonies and produced quartets, doublets, and single sporangia. A sporangium consisted of a conical stem, a swollen middle cell, and an endogenous spore.
