Improved Assay Technique for Coxiella Burnetii in Chick Embryo.
The egg 50% lethal doses (IiD5o) for Coxiella burnetii range from 105 to 10-6, whereas the 50% infectious doses (ID5o) determined by microscopic examination range from 10-10 to 10-11 (Weiss and Pietryk, J. Bacteriol. 72:235, 1956; Pickens and Gaon, Am. J. Trop. Med. Hyg. 10:49, 1961). If the LDno value for eggs could be increased, dilute suspensions of rickettsiae could be assayed without the t...

متن کاملCoxiella burnetii pneumonia.
This report reviews the pulmonary and extrapulmonary manifestation of infections due to Coxiella burnetii. Q fever, a zoonosis, is due to infection with C. burnetii. This spore-forming microorganism is a small gram-negative coccobacillus that is an obligate intracellular parasite. The most common animal reservoirs are goats, cattle, sheep, cats, and occasionally dogs. The organism reaches high ...
