In vitro susceptibilities of Rickettsia rickettsii, Rickettsia conorii, and Coxiella burnetii to the new fluoroquinolone sparfloxacin (AT-4140; RP 64206) were determined. Plaque and dye uptake assays were used to measure the MICs against R. rickettsii and R. conorii. The susceptibilities of C. burnetii Nine Mile and Q 212 were determined in two acute-infection models and in ...

ABSTRACT In vitro activities of telithromycin compared to those of erythromycin against Rickettsia spp., Bartonella spp., Coxiella burnetii , and Ehrlichia chaffeensis were determined. Telithromycin was more active than erythromycin against Rickettsia , Bartonella , and Coxiella burnetii , with MICs of 0.5 μg/ml, 0.003 to 0.015 μg/ml, and 1 μg/ml, respectively, but was inactive against Ehrlichia chaffeensis .

Summary Viable rickettsiae were isolated from the lymphatic tissues of a patient one year following recovery from Rocky Mountain spotted fever. The recovered agent was maintained by serial passage in guinea pigs and fertile hens' eggs. Identity of the isolated agent was established by: The development of specific complement fixing antibodies in guinea pigs.Direct visualization of the microorganisms in yolk sac tissues.The demonstration of its ability to afford cross immunity to a standard laboratory ...
