Synergistic Killing and Re-Sensitization of to Antibiotics by Phage-Antibiotic Combination Treatment.

Multidrug-resistant (MDR) infections pose a serious health threat. Bacteriophage-antibiotic combination therapy is a promising candidate for combating these infections. A 5-phage cocktail, PAM2H, was tested in combination with antibiotics (ceftazidime, ciprofloxacin, gentamicin, meropenem) to determine if PAM2H enhances antibiotic activity.

Neutralizing antibody VRC01 failed to select for HIV-1 mutations upon viral rebound.

Infusion of the broadly neutralizing antibody VRC01 has been evaluated in individuals chronically infected with HIV-1. Here, we studied how VRC01 infusions affected viral rebound after cessation of antiretroviral therapy (ART) in 18 acutely treated and durably suppressed individuals. Viral rebound occurred in all individuals, yet VRC01 infusions modestly delayed rebound and participants who showed a faster decay of VRC01 in serum rebounded more rapidly.
