| Staining | The infectious forms are Gram-negative rod- or disk-shaped organisms, usually smaller than those of the genus Rickettsia, but developing intracellularly into larger particles that multiply and reform the smaller forms in a cycle that resembles that of Chlamydia. Sometimes produce or induce the formation of large crystalline bodies. Growth takes place in cell vacuoles of the fat body, hepatopancreas, and other organs of invertebrate hosts. In some instances they have been cultivated in invertebrates other than the host of origin and rarely and only for a few passages in vertebrate and invertebrate cell cultures. Have not been grown in cell-free media. Pathogenic for their larval hosts and young and mature stages of other invertebrate hosts, but of little virulence for vertebrates. Natural hosts include insects, crustaceans, and arachnids. |
