Why M. avium should be so susceptible to essential oil vapors is not known. One possible explanation might he the fact that this organism was exposed to the vapors for a longer period of time (seventy-two hour incubation period) and hence greater susceptibility due to greater absorption of t h e vapors on to the agar. One might speculate as to the possible mode of action involving a penetration of the essential oil vapor into the cell barrier disrupting the chemical organization (lipids) of the cell.
