Pathogenic Acinetobacter cause a variety of diseases in humans including ventilator-associated pneumonia, community acquired pneumonia and wound/surgical site infections. Alarmingly, these infections are becoming increasing non-responsive to antibiotic therapies due to the ability of Acinetobacter spp. to acquire and exhibit antibiotic resistance. We have recently shown that Acinetobacterspp. utilize a secretion system, the type VI secretion system (T6SS), to compete with other bacteria. The T6SS is a poison tipped, spring-loaded dagger that certain bacteria can produce and use to intoxicate and potentially kill neighboring bacteria or host cells. My research focuses how Acinetobacter produces its T6SS, what specific proteins mediate the T6SS-associated anti-bacterial effects and determining what role the T6SS has in the diseases caused by Acinetobacter spp.PublicationsCarruthers, M.D., Harding, C.M., Rather, P.N., Bonomo, R.A. and R.S.
