Sentence examples for decrease in the virulence from inspiring English sources
These genetically attenuated parasites (GAP) can either become developmentally arrested subsequent to invasion of liver cells [10] or infections with those GAPs that are associated with a marked decrease in the virulence in the host[11], [12], [13].
Functional experiments revealed a dramatic decrease in the virulence of 05ZYH33 following the disruption of the TCS in the 89K GI [15].
In conclusion, we observed a remarkable decrease in the virulence of Nocardia brasiliensis HUJEG-1 after subculturing it 130 times in vitro, compared to the parent strain.
As such, the decrease in expression of this regulator under NaCl- and KCl-induced stress may be associated with a decrease in the virulence of the pathogen.
To assess whether the inactivation of the oppD gene in C. pseudotuberculosis resulted in a decrease in the virulence profile of the mutant strain, infection assays using BALB/c mice were performed.

Reduced virulence of TC-adapted KFDV: Bhatt and Anderson have reported that the passage of the prototype P9605 strain of KFDV in monkey kidney tissue culture (MKTC) resulted in a decrease of the virulence of the virus for adult mice as judged by a decrease in LD50 titer of the virus following intraperitoneal (IP) inoculation.
