Arboviral and rickettsial
infections among combat troops during Operation Desert Shield/Storm.
Various serological tests that can be done to diagnose rickettsial
infections are microimmunoflorescence, immunoperoxidase assay, latex agglutination, indirect hemagglutination, enzyme-linked immunosorbent assay, dot blot immunoassay (including dipstick test) and Weil-Felix test.
Cascading effect of economic globalization on human risks of scrub typhus and tick-borne rickettsial
diseases--Rocky Mountain spotted fever.
22) Like spotted fever group rickettsial
diseases, Q fever is a tick-associated zoonosis, with an extremely wide host range.
diseases are widely distributed throughout the world and many recent reports suggest to their continued presence in several parts of the Indian subcontinent, particularly that of scrub typhus (3-8).
1 Interestingly, 13 of these patients were treated with penicillin without therapeutic benefit, further implicating a rickettsial
Diagnosis is usually made by obtaining serial serum titers (10 to 14 days apart) for specific rickettsial
organisms or by using polymerase chain reaction amplification to detect rickettsial
DNA (8, 9).
panel and histoplasmosis and coccidioidomycosis serologies were negative.
A wide spectrum of infectious diseases are discussed in Chapter 5, including bacterial, viral, mycoplasmal, rickettsial
, fungal, and parasitic.
His present work is focused on rickettsial
organisms associated with common, human-biting ticks.
Cutler of the CDC's division of viral and rickettsial
diseases said in a presentation at the symposium, which was sponsored by the U.
We deal primarily with human health and public health issues at the CDC,'' said Chris Paddock, medical officer with the Viral and Rickettsial
Zoonoses Branch of the CDC in Atlanta, Ga.
Only about 20 percent of the cases described in the CDC study were initially diagnosed as rickettsial
Ehrlichiosis is a rickettsial
infection first found in humans in 1986.
