Open publisher page 6 citations

Abstract

A new species of Nosema (Microsporida) is recorded in two species of Branchinecta. In the first year of occurrence (1970) 100% of B. gigas and 91% of B. mackini were infected at the beginning of June. Mortality of infected animals was much higher than of uninfected ones. Infections recurred in 1971 with maximum values of 47% and 57% in B. gigas and B. mackini, respectively, and in 1972 with values of <10% in each, but they were not evident in 1973. No effect on host egg production was detected.
