Although the precise mechanism by which the bba64 gene product causes attenuated infectivity for mice by tick bite remains to be defined, data presented herein significantly advances our understanding for this protein's role in B. burgdorferi pathogenesis.
For example, a virus such as that which causes measles may be attenuated (weakened) and used as an immunizing agent.
Another, Dr. Cherry said, would be to add an attenuated form of the bacterium's toxin, which causes the disease's symptoms, or return to a whole-cell vaccine with an attenuated toxin.
The enzymatic activity of COMT is attenuated by the occurrence of a single nucleotide polymorphism (G>A) which causes an amino acid substitution (from a valine (Val) to a methionine (Met) residue) at codon 158 [ 3].
It is made by growing Mycobacterium bovis (which causes tuberculosis in cows) in the laboratory until its genes mutate, causing the bacterium to become attenuated--that is, loses the ability to cause disease but still stimulates the immune system.
