Efficacy of Newly Isolated and Highly Potent Bacteriophages in a Mouse Model of XDRAB Bacteremia.

Bacteremia can be caused by Acinetobacter baumannii with clinical manifestations ranging from transient bacteremia to septic shock. Extensively drug-resistant A. baumannii (XDRAB) strains producing the New Delhi metallo-ß-lactamase, which confers resistance to all ß-lactams including carbapenems, have emerged and infected patients suffer increased mortality, morbidity and length of hospitalization. The lack of new antimicrobials led to a renewed interest into phage therapy, the so-called forgotten cure. Accordingly, we tested new lytic bacteriophages in a Galleria mellonella and a mouse model of XDRAB-induced bacteremia.Galleria mellonella were challenged with 5.105 CFU of the XDRAB strain FER. Phages vB_AbaM_3054 and vB_AbaM_3090 were administrated…
