Plistophora sp.
Natural host.—Blatta orientalis, France (Mercier, 1908a): The organism parasitized the fat body of the cockroach. Mitoses, often abnormal, were induced in the fat cells. Infected cockroaches were easily recognizable by their distended abdomens. The fat body became chalky white and showed through the intersegmental membranes.
Porter (1930) reported finding an unidentified microsporidian in the fat bodies of Blattella germanica and Periplaneta americana collected in South Africa. It may or may not have been a species of Plistophora.
