Experimental 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 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 کاملThe Pathogenesis of Meningococcus Meningitis in the Chick Embryo
1. A microscopic and bacteriological analysis of the meningitis produced in the chick embryo following inoculation of meningococci into the body wall or into the amniotic cavity indicates that the meninges are invaded by way of the blood stream. 2. There is no indication that a direct extension of the infection by way of the middle ear, the cranial sinuses or the pia-arachnoid sheath of the olf...
متن کاملA Study of Passive Immunity to Meningococcus Infection in the Chick Embryo
1. 14 day old chick embryos are protected against subsequent meningococcus infection through the amniotic route by the intravenous administration of an homologous antiserum produced in hens, by a commercial concentrated polyvalent meningococcus antiserum and by a commercial meningococcus antitoxin. 2. Titrations of the different antisera indicate that the homologous and commercial polyvalent se...
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...
