Variation of host resistance to influenza viruses in the allantois [PDF]

open access: yesJournal of Hygiene, 1959
1. Methods are described for altering the susceptibility of the surviving allantois to infection by influenza viruses.2. Under natural conditions susceptibility is a linear function of age between 10 and 18 days of incubation. The drop is 0·11 log10unit per day for all strains of influenza tested.3. In whole eggs this decline is masked by the effect of

Mesothelium of the murine allantois exhibits distinct regional properties [PDF]

open access: yesJournal of Morphology, 2011
AbstractThe rodent allantois is thought to be unique amongst mammals in not having an endodermal component. Here, we have investigated the mesothelium, or outer surface, of murine umbilical precursor tissue, the allantois (∼7.25–8.5 days postcoitum, dpc) to discover whether it exhibits the properties of an epithelium.
