| In addition, influenza viruses are usually passaged in embryonated chicken eggs before isolation. |
|
| Particularly worrisome is the fact that the highly pathogenic H5 and H7 subtypes of the flu virus kill embryonated chickens eggs. |
|
| Absence of c-DNA of A influenza virus in material obtained from dead chickens and in inoculated embryonated hen eggs. |
|
| This TCF was effectively used to infect embryonated chicken eggs. |
|
| The antigen is prepared from virus grown in the allantoic cavity of embryonated hen's eggs. |
|
| Viral cultures are being carried out on embryonated eggs in order to isolate the virus and determine its intracerebral pathogenicity index. |
|
| For example, it's unlikely we would have enough embryonated eggs available for emergency use. |
|
| The influenza viruses multiply very effectively in the embryonated hen's eggs. |
|
| The need for embryonated eggs as a growth medium for viral or rickettsial agents makes their use unlikely. |
|
| The presence of the virus of visceral lymphomatosis in embryonated eggs of normal appearing hens. |
|
| Maceration, utilising a mechanical apparatus with rotating blades or projections, causes immediate fragmentation and death in day-old poultry and embryonated eggs. |
|
| Material from carcases and cloacal swabs were submitted for virological examination by inoculation into both embryonated fowl eggs and cell culture. |
|
| If bacteria are present, the fluids may be passed through a 450 nm membrane filter, further antibiotics added and inoculated into embryonated eggs as above. |
|
| In addition, a cell-based production process for influenza vaccines has the advantage that it is not dependent on the availability of embryonated chicken eggs, the supply of which can be at risk in case of bird flu. |
|
| Strains will be grown on conventional media and also passaged through in vitro cell culture and embryonated eggs, and then hybridised against the Campychip microarray for comparison. |
|
| The tracheal swabs were tested for influenza A antigen. In addition, the tracheal and cloacal swabs were tested using a three-passage inoculation of SPF embryonated chicken eggs. |
