Experimental Gonococcus Infection of the Chick Embryo
1. The reaction of the chick embryo to nine strains of gonococci was studied. Four of these were inoculated intra-amniotically in 14 to 15 day embryos. 2. Infection of the 10 day chorio-allantoic membrane was localized and accompanied by polymorphonuclear leucocytic phagocytosis. 3. Infection was either transitory or persisted until hatching. Several strains killed the 10 day embryo in 3 days. ...
متن کاملExperimental Meningococcus Infection of the Chick Embryo
1. A strain of meningococci obtained directly from the spinal fluid of a patient has been propagated in serial passage in 10 to 12 day old chick embryos without change in its essential characteristics. 2. The chick embryo is susceptible to infection with the meningococcus, and, depending on its stage of development, reacts to the infection with more or less specific lesions. 3. In chick embryos...
متن کاملExperimental Lathyrism in the Chick Embryo
1. C(14)-labeled beta-aminopropionitrile distributed throughout the egg contents within 10 minutes postinjection. By ion exchange chromatography and electrophoretic analysis three major components of the extractable dialyzable radioactive material could be demonstrated, representing at least 80 per cent of the total. The acidic and basic components were identified as beta-aminopropionitrile and...
متن کاملThe Course of Experimental Infection of the Chick Embryo with the Virus of Equine Encephalomyelitis
The titration curve for the virus of Eastern equine encephalomyelitis inoculated into the 10 day old chick embryo shows that the maximum increase in virus content continues until shortly before the generalized destruction of the embryo is apparent. This is followed by a stationary phase. Histological studies of infected embryos fail to demonstrate selective tissue destruction, and titrations sh...
متن کاملExperimental Infection of the Chick Embryo with the Virus of Pseudorabies
The chick embryo responds to experimental infection with the virus of pseudorabies with a disease pattern simulating the natural infection. Virus lesions of the membrane are followed by infection of all tissues of the central nervous system. Fixed strains produce a hemorrhagic destruction of the central nervous system of the embryo, which is referable to destruction of blood vessel endothelium....
