And no doubt some of you understand the basis of the simple mutations that can influence gene function, such as point deletions (which would make you blood group […]

Many bacteria are capable of altering their genetic expression based upon an assessment of their environmental conditions and a novel approach to controlling bacterial infection may involve interfering with the ability of one bacteria to communicate with another. Interestingly, their modus operandi also makes good New Age music.

A new study on the role of mucosal immunity and host genetics in defining intestinal commensal bacteria indicates that basic elements of gut immunity, such as antibody secretory IgA (sIgA) exert profound effects on the composition of the bacterial flora that inhabit the gut.
