Efficacy of gelatin hydrogels containing paenipeptin analogue 1, clarithromycin, or their combination against Acinetobacter baumannii ATCC 19606 in murine skin wound infection (n = 4, female CD-1 mice). A Treatments at 4 h post infection; B Treatments at 20 h post infection. PBS: hydrogel in PBS without antimicrobials (negative control); Paen1: hydrogel with 0.1 mg/ml paenipeptin analogue 1; CLR: hydrogel with 0.1 mg/ml clarithromycin; Paen1+ CLR: hydrogel with 0.1 mg/ml paenipeptin analogue 1 and 0.1 mg/ml clarithromycin. Means with different letters are significantly different between groups (p < 0.05)
