Phage Plaque Test for Counting Viruses

Bacteriophages, or phages, are viruses that infect prokaryotic cells. The plaque assay is a classic way to count these viruses by measuring viral titer, which is the amount of virus in a sample. It was first described in 1952 and is still one of the most reliable methods for determining viral titer.

Los bacteriófagos, también llamados fagos, son virus que infectan específicamente a las bacterias y podemos confirmar su presencia y cuantificarlos utilizando una herramienta llamada ensayo de placa. Los bacteriófagos infectan a sus huéspedes susceptibles adhiriéndose primero a la pared celular bacteriana e inyectando su material genético. Luego...
