This chapter describes Rickettsiaceae, small, aerobic, gram-negative coccobacilli that are obligate intracellular parasites of eukaryotic cells. It identifies three groups of Rickettsiae groups based on clinical presentation: the spotted fever group, the typhus group, and scrub typhus.

Rickettsial and ehrlichial infections
2010Rickettsial diseases represent a clinically homogeneous group of infections characterized by fever, headache myalgias, variable presence of a rash, and a broad spectrum of neurological manifestations. Epidemiological information including time of year, geography, history of arthropod exposure, and animal contact gives important clues to the diagnosis ...

Veterinary Clinics of North America: Small Animal Practice, 2000
Dogs that live in tick-infested areas are at risk for contracting rickettsial infections. Clinical signs associated with ehrlichiosis or Rocky Mountain spotted fever may be dramatic or mild. Clinicians must consider the possibility of rickettsial diseases to request laboratory tests that will permit a proper diagnosis.

Rickettsial infections are caused by a variety of obligate intracellular, Gram-negative bacteria from the genera Rickettsia, Orientia, Ehrlichia, and Anaplasma. Rickettsia is further subdivided into the spotted fever group and the typhus group. Bartonella and Coxiella burnetii bacteria are similar to rickettsiae and cause similar diseases. The range of

Seroepidemiology of rickettsial infections in Morocco
European Journal of Epidemiology, 1995The prevalence of antibodies reactive with Rickettsia conorii, Rickettsia typhi, Coxiella burnetii and Ehrlichia chaffeensis was investigated using indirect immunofluorescence (IFA) test on human sera obtained from 300 blood donors in Casablanca and 126 sera obtained from clinical laboratories in Fez.

Rickettsial infections - a threat to travellers?
Current Opinion in Infectious Diseases, 2004Recent developments in cell-culture techniques and molecular methods have led to the description of several new rickettsial diseases. An update on these new infections should be of interest to health workers with patients who are international travellers.Epidemic typhus was reported last year in the United States when an outbreak of murine typhus was ...

Chloromycetin in Experimental Rickettsial Infections
The Journal of Immunology, 1949Summary Experimental data were presented which indicated that chloromycetin has a rickettsiostatic effect in embryonated eggs infected with R. tsutsugamushi, R. mooseri, R. rickettsi, R. akari, R. prowazeki and R. burneti. Chemotherapeutic tests in mice or guinea pigs infected with any one of the first four agents listed also gave ...

Rickettsial infections in the tropics and in the traveler
Current Opinion in Infectious Diseases, 2013The purpose of this review is to describe recent advances in our understanding of the pathogenesis, epidemiology, and clinical features of rickettsial diseases with emphasis placed on those relating to travel and tropical medicine.Rickettsioses are becoming increasingly recognized as causes of febrile illness in travelers and in those residing in the ...
