Sentence examples for lack of virulence from inspiring English sources

Although the 1,695 nt deletion in the outer membrane protein is consistent between S19 and both the virulent strains, further studies are needed to associate this protein to the lack of virulence in S19, as further examination of the same ORF in other virulent species of Brucella reveals the presence of similar deletions (Figure 3) in B. melitensis and B. suis.

Viruses don't decide how deadly to be; for humanity, H1N1's relative lack of virulence was just plain luck.

The lack of virulence of this bacterium could also explain a relatively low mortality.

This suggests the lack of a clear-cut association with the lack of virulence.

However cheaters, due to their lack of virulence factors, have decreased infectiousness and Smith proposed that horizontal gene transfer was a possible mechanism to minimize "cheater" strains and restore infectiousness in the pathogen population.

While the down-regulation of the streptolysin S operon may contribute to the reduced virulence, this finding implies that the loss of SpeB in this strain is the main cause of the lack of virulence exhibited.

The increased abundance of monoacylated ManLAMs molecules and lack of virulence-associated immunomodulatory cell wall lipids, such as DAT and PAT, (involved in mycobacterial interaction with host cells [31]), could play part in the adherence phenotype displayed by SO2.

The low frequency of LIII in human listeriosis can be partially explained by its overall rarity in foods, lack of unrecognized virulence factors, or defective mutation in some known virulence factors.

Although the presence of similar deletions in other virulent species eliminates the possibility of association of the deletion to lack of general virulence, it is possible that the deletion may be associated with species specific (B. abortus) host preference, which needs to be tested in mutation experiments.

These genes are also present in the systemically avirulent unencapsulated strain BS293, but this strain's lack of systemic virulence is attributable to its lack of capsule.

The lack of these virulence factors was also confirmed by serological tests conducted (data not shown).
