These smallest organisms have an extraordinary ability of undergoing phase and antigenic variation
that alters the cell architecture and hence helps in successful survival of these small genome bearing pathogens.
falciparum might have a key role in antigenic variation
Substantial antigenic variation
of seasonal H1N1 viruses was found in the late 1940s before the influenza A (H2N2) pandemic in 1957.
Present study was planned to investigate the antigenic variation
It was concluded that there was little antigenic variation
among different strains of MG prevalent in Pakistan and SDS-PAGE along with western blotting can be used for molecular characterization of MG isolates.
Moreover, antigenic variation
also existed among the 6 A/peregrine falcon/Hong Kong/810/2009-like viruses, as highlighted by the HI assay using k0602 antiserum (Table 1).
However, as type A(H1N1) viruses continue to undergo antigenic variation
(which occurs among all influenza viruses), the effect of these strains among elderly persons may change.
Genetic and antigenic variation
of capsid protein VP7 of serotype G1 human rotavirus isolates.
However, long-term control of influenza by vaccination is complicated by the propensity of the virus for antigenic variation
Thus, the genetic and antigenic variation
among JEV strains circulating in India should be monitored to determine effects on JE epidemiology and ongoing vaccination efforts.
Eradication of ALV-J has been difficult because of substantial genetic and antigenic variation
among ALV-J isolates as well as high levels of vertical and horizontal transmission (9,10).
Antigenic divergence suggested by correlation between antigenic variation
and pulsed-field gel electrophoresis profiles of Bordetella pertussis isolates in Japan.
However, these cases might be caused by antigenic variation
A/canine/Jacksonville/2005 has potentially significant antigenic variation
from the other canine isolates, which may be partially related to the proline substitution at position 107.
He then moves on to more recent discoveries regarding immunity, antigenic variation
, and the role of variable surface glycoproteins.
