Growth and lethal effects of the psittacosis agent in chicken embryos of different ages.

Stewart, Robert B. (University of Rochester, Rochester, N. Y.). Growth and lethal effects of the psittacosis agent in chicken embryos of different ages. J. Bacteriol. 83:423-428. 1962.-Inoculation of the psittacosis agent (strain 6BC) into the yolk sacs of chicken eggs in different stages of embryonic development resulted in a steady decrease in ld(50) titer as the embryos increased in age from...

Endocarditis caused by a psittacosis agent.

Psittacosis I. Experimentally Induced Infections in Parrots

The widespread outbreak of psittacosis in man in 1929-30 led to renewed interest in the disease which quickly resulted in the discovery of the facts that the causative agent is not Nocard's bacillus but a filterable virus (1) and that the incidence of laboratory infections is high. Because of these facts it became imperative that further work on the nature of the etiological agent and the mode ...

Vaccination of Monkeys and Laboratory Workers against Psittacosis

Monkeys that have recovered from psittacosis pneumonia have an increased resistance to infection with the virus and possess neutralizing antibodies in their sera. Large amounts of active psittacosis virus can be introduced intravenously and intramuscularly into monkeys without the production of a serious infection such as pneumonia. Relatively small amounts of virus introduced intratracheally i...

A Virus from Cases of Atypical Pneumonia Relation to the Viruses of Meningopneumonitis and Psittacosis* by Monroe

The isolation of three different etiologic agents from atypical bronchopneumonias has recently been reported. Dyer, Topping, and Bengston (1) have described an outbreak of pneumonitis apparently resulting from laboratory infections in which the rickettsiae of American Q fever were shown to be the cause. Weir and Horsfall (2) have reported infection of the mongoose with a filterable agent from c...
