avirulence

the attenuated strain exhibited complete avirulence in animal models.

understanding avirulence mechanisms is crucial for vaccine development.

researchers investigated the genetic basis of avirulence in the pathogen.

natural avirulence can arise through mutations in virulence factors.

the goal was to engineer a strain with stable avirulence.

avirulence is a key characteristic of beneficial microbial symbionts.

screening for avirulence is a common step in biocontrol agent development.

the plant showed no symptoms due to the avirulent fungal strain.

loss of avirulence can occur if the pathogen regains virulence genes.

the study focused on identifying genes associated with avirulence.

engineered avirulence provides a safer option for certain applications.
