Entry of Rickettsia tsutsugamushi into polymorphonuclear leukocytes.
Factors involved in the phagocytosis and entry into polymorphonuclear leukocytes (PMNs) of Rickettsia tsutsugamushi were studied by electron microscopy. R. tsutsugamushi propagated in baby hamster kidney cell cultures was incubated with guinea pig peritoneal PMNs in vitro at 35 degrees C. Structurally intact and degenerating rickettsiae were found in phagosomes, but only intact rickettsiae esca...

Hyperimmune antirickettsial serum was shown to prevent the attachment/penetration stage of Rickettsia tsutsugamushi infection of suspended chicken cells. The extent of the inhibition depended on the serum concentration but not on the presence of complement. The neutralizing activity was reduced by prior adsorption of immune serum with staphylococcal protein A or with intact rickettsiae but was ...
