Adult cockroaches, Bieberus craniifer, were injected with an antibiotic to reduce the number of symbiotic bacteroids in the abdominal fat body and to determine the effect of their reduction on hemolymph protein levels. The animals were Injected with Penicillin G (Crystalline-Potassium) in consecutive doses of 1000 units for a period of 15 days. Hemolymph samples were collected, and electrophoretic analyses made employing cellulose polyacetate strips as a support medium. Three trials were conducted using 280 cockroaches. The treatment had a definite effect on 2 of the 3 proteins which were consistently demonstrated in the controls by the analysis used. Two bands either disappeared or were greatly diminished. The remaining band simultaneously Increased in intensity. The results linked the intracellular bacteroids with protein synthesis, growth, and reproductive processes.
