Studying Evolutionary Adaptation of MERS-CoV.

Area of Science:

• Virology
• Molecular Biology

Background:

• Forced viral adaptation is key to understanding viral evolution under selective pressures.
• Studying viral replication mechanisms is crucial for developing antiviral strategies.

Purpose of the Study:

• To describe methods for in vitro serial passaging of MERS-CoV.
• To select for MERS-CoV mutations that improve replication in semi-permissive cell lines.

Main Methods:

• In vitro serial passaging of Middle East respiratory syndrome coronavirus (MERS-CoV).
• Selection of viral mutants demonstrating increased replication efficiency.

Main Results:

• Established a protocol for MERS-CoV adaptation.
• Identified mutations conferring enhanced replication in semi-permissive cells.

Conclusions:

• The described methods facilitate the study of MERS-CoV adaptation.
• This approach aids in understanding viral evolution and identifying replication determinants.
