Given the resource constraints of many clinics and ecological challenges of Kenya, such as the illegality of sex among MSM, interventions to address HIV must strategically engage this population.

In and out: an analysis of epibiotic vs periplasmic bacterial predators.

Bdellovibrio and like organisms (BALO) are obligate predators of Gram-negative bacteria, belonging to the α- and δ-proteobacteria. BALO prey using either a periplasmic or an epibiotic predatory strategy, but the genetic background underlying these phenotypes is not known. Here we compare the epibiotic Bdellovibrio exovorus and Micavibrio aeruginosavorus to the periplasmic B.
