Hazardia is a genus of microsporidians that parasite insects, with the type host being Culex pipiens.[1] It is currently classified as incertae sedis within the order Amblyosporida of phylum Rozellomycota.[2]
Description
Hazardia is characterized by three sporulation sequences that occur primarily in the fat body of larval mosquitoes:[1]
First sequence: small, oval binucleate spores are generated, and they encyst into sporonts.
Second sequence: diplokaryotic (i.e. with paired nuclei) sporonts divide through binary fission to produce lanceolate, thick-walled binucleate spores with a rugose exospore.
Third sequence: the most common sequence, it involves uninucleate sporonts that form sporogonial plasmodia that divide by multiple fission producing between 2 and 16 uninucleate spores (usually 8) that are pyriform and thin walled.
Ecology
The transmission of Hazardia between mosquitoes is per os, meaning through the mouth.[1]
Taxonomy
There are two species:
Hazardia milleri (Hazard & Fukuda 1974) Weiser 1977 (type species)[1]
Hazardia usbekistanica Khodzhaeva 1988[3]
