Survival of variola virus in chorioallantoic membrane preparations.
The transmission of smallpox by contaminated bed clothes (Stallybrass, 1931) and by dust from the floor of a patient's room (Downie and Dumbell, 1947) is evidence of the stability of variola virus under natural conditions. Experimental proof of the survival of variola virus in exudates and crusts from humans was reported by Buddingh (1938) and North et al., (1944). The former investigator noted...
متن کاملFactors influencing variola virus growth on the chorioallantoic membrane of embryonated eggs.
The propagation of variola virus on the chlorioallantoic membrane of embryonated eggs was first reported by Torres and Teixeira (1935). Application of this finding was made by Lazarus et al. (1937), Buddingh (1938) and Markham and Bozalis (1939) who utilized embryonated eggs as a diagnostic medium. Nelson (1940, 1943), described the development and stability of variola virus in egg passage but ...
متن کاملSmallpox eradication. Destruction of variola virus stocks.
1. The global eradication of smallpox was confirmed in 1980 (resolution WHA33.3). From 1981 to 1986, WHO undertook a programme to implement the post-eradication policies contained in the 1979 report of the Global Commission for the Certification of Smallpox Eradication and endorsed by the Health Assembly in resolution WHA33.4. Progress was reviewed year by year from 1981 to 1984 by the WHO Comm...
متن کاملImmunofluorescence staining for detection of variola virus.
In September 1975 Bangladesh was the only country in the world with endemic variola major, and the eradication of the disease was imminent. A rapid and accurate laboratory diagnostic method was required to supplement immunodiffusion in agar gel and culture on chorioallantoic membrane of embryonated egg available at the Institute of Public Health in Dacca, Bangladesh. To determine its effectiven...
متن کاملAdaptation of infectious bronchitis virus in primary cells of the chick embryo chorioallantoic membrane
The susceptibility of the primary chick embryo chorioallontoic membrane cells to infectious bronchitis virus was evaluated after twenty consecutive passages in chick embryo chorioallontoic membrane cells. Virus replication was monitored by cytopathic observation, indirect immunoperoxidase, and reverse transcription polymerase chain reaction (RT-PCR). At 72 hours post-infection (p.i.) in third p...
