Metschnikowia bicuspidata
Introduction
Metschnikowia is a genus in the Kingdom Fungi (Naumov, 2011). Metschnikowia species are single-celled (i.e., yeast) parasites of the freshwater zooplankton genus Daphnia (ibid.).
Description and Significance
___only one morphological form has been observed.
The organism exists as single-celled needle-shaped spores (Naumov, 2011). __dimensions Metschnikowia lives in freshwater lakes ___where? It survives by ___ It is a pathogen of Daphnia; a spore uses the host's body as a reproduction factory. After puncturing the gut wall, it uses energy from the host? to produce thousands of identical spores. These increase in number until the Daphnia body bursts; a single Daphnia carcass can contain up to ___ spores, with typical numbers near ___.
__second host?
