| ultrastructure of developmental stages of hemolivia mariae (apicomplexa: haemogregarinidae), natural parasite of the australian sleepy lizard, in experimentally infected deviant hosts. | mabuya vitatta (olivier) (scincidae) and agama stellio (l.) (agamidae) were infected with hemolivia mariae smallridge et paperna, 1997 by ingestion of tick viscera from amblyomma limbatum neumann, fed as nymphs on naturally infected australian sleepy lizards, tiliqua rugosa gray. the unnatural infection apparently interfered with the developmental schedule of the parasites. transmission electron microscopic images of merogonic stages were obtained, as well as images of early developing gametocyt ... | 2001 | 11817448 |
