| Ultrastructural observations shows in the testis of where and cytoplasm are excluded from the mature sperm, and also found either in somatics and reproductive organ of Details of the ultrastructure of from the reproductive and somatic organs of harbour - induce popcorn-effect and harbour -induce cytoplasmic incompatibility are described as follows: the ultrastructure of in both of them were similar, distribution of in was not restricted to the reproductive organs, they were also found in somatic tissues (muscle). can be present without causing detrimental effects. They are pleomorphic (rod shaped, elongate, oval or slightly bent). The size varies between 0.04 µm and 0.47 µm in diameter and between 0.26 µm and 1.2 µm in length. In a few cases seem to have been undergoing fission, but are still joint together by a vacuolar membrane. The microorganisms appear to have two membranes, a host membrane and a bacterial membrane. However, in some cases the microorganism seems to be surrounded by only one membrane, the possibility why only one membrane was visible might be due to loss during the embedding process. |
