Transmissibility and pathogenicity of resistant strains appear similar to those of susceptible strains. In 2006, the circulating influenza A virus rapidly became resistant to the adamantanes ...

Subjects with 3TC-resistant virus stopped taking 3TC and sustained an increase in viral load. A single mutation at codon 184 in the HIV genome results in high-level 3TC resistance, but it may also ...

Antibiotic resistance is a serious problem, especially in hospitals. ... So you always have to hunt for the right virus each time. Gill knows from experience how complicated the approach can get.

Harvard-led researchers revealed how herpes simplex virus (HSV) develops resistance to antiviral drugs through changes in protein dynamics, not just mutations at drug-binding sites. Using cryogenic ...

Pavia pointed to the example of SARS-CoV-2, the virus that causes COVID-19, which developed resistance to treatment with monoclonal (laboratory-made) antibodies within a matter of months each time ...
