OsHV-1 and notifiable protozoa in healthy Crassostrea corteziensis cultured in two distant areas of the Gulf of California

ABSTRACT Infectious diseases have been a major limiting factor for large scale production of oyster farming. Several factors have contributed to the emergence and spread of infectious diseases in all cultivation sites around the world. Therefore, the prevention and control of diseases has become a p...
