Abstract

Alternative therapeutic options are urgently needed against multidrug-resistant infections, especially in situations of preexisting tigecycline and colistin resistance. Here, we investigated synergistic activity of the antiretroviral drug zidovudine in combination with tigecycline or colistin against harboring (X) and and in a murine thigh infection model. Zidovudine and tigecycline/colistin combinations achieved synergistic killing and significantly decreased bacterial burdens by >2.5-log CFU/g in thigh tissues compared to each monotherapy.
