Why are the genes for bacterial virulence factors are often carried by mobile DNA.? are the bacterial virulence factors of any immediate metabolic benefit(s) to the career, in this case the bacteria.?
well.. it may be because of quick regulation of genes under required conditions and it can maintain a high copy number.
These genes, the bacterial virulence factors, do not have an immediate metabolic benefit to the organism. May be they are beneficial in "not a direct" way as in making the surrounding environment more favorable for there reproduction.(?) this is interesting because if we can not kill the organism (if we should), may be we can limit the bacterial virulence factors from spreading.(?)
