Specifically, we analysed the in vitro activity of BMAP-27 and -28 and of their analogs against a wide panel of Gramnegative and -positive clinical isolates, also including many antibiotic-resistant strains, and against the human herpes simplex virus type 1 (HSV-1). The in vitro antibacterial activity of purified BMAP peptides and of their analogs was determined as the minimum inhibitory concentration (MIC) by a microdilution susceptibility test in 96-well microtiter plates, according to the guidelines of the National Committee for Clinical Laboratory Standards (NCCLS). The potential of BMAPs to protect mice from a bacterial challenge was tested in a model of acute peritonitis induced by i.p. injection of a lethal dose of P. ./cache/cord-321417-6code4oh.txt ./txt/cord-321417-6code4oh.txt
