Most virulence factors are coordinately regulated in pathogenic Bordetellae by a single master regulator, the BvgAS two-component system [ 42, 43].
If Helicobacter infection was the master switch in the pathogenic circuitry, its eradication should halt progression.
Total RNA from the all the pathogenic agent studies was reverse-transcribed simultaneously using the same master mix.
A pathogen is defined by its ability to be, well, pathogenic.
It is therefore evident that this master regulator of morphological transitions has a conserved function between several of the most pathogenic Candida species.
Though being an environmental isolate, the sequenced B. petrii strain also encodes proteins related to virulence factors of the pathogenic Bordetellae, including the filamentous hemagglutinin, which is a major colonization factor of B. pertussis, and the master virulence regulator BvgAS.
It is now highly pathogenic to chickens.
"But that was a high pathogenic strain.
Pathogenic (P) variants comprised of.
