The symbiotic bacteria of the fat body of Blattella germanica L. (Blattodea) were eliminated by giving the insects chlortetracycline during their whole nymphal and adult life. The loss of the bacteria caused extensive structural changes, both of the nucleus and of the cytoplasm, to take place in the bacteriocytes of the individuals treated. These changes were much greater in the bacteriocytes that were completely devoid of their symbiotic complement: they were no longer able to divide and thus increased considerably in size. These bacteriocytes appeared to be different from those of individuals whose parents were treated with antibiotic, as regards both the structure and the arrangement within the lobes of the fat body.
