TI  - Susceptibility of shellfish aquaculture species in the Chesapeake Bay and 
      Maryland coastal bays to ostreid herpesvirus 1 microvariants.

AB  - Ostreid herpesvirus 1 (OsHV-1) and its microvariants (microVars) cause economically 
      devastating mass mortalities of oysters and pose a threat to the shellfish 
      aquaculture industry globally. OsHV-1 outbreaks can cause up to 100% mortality in 
      the Pacific oyster Crassostrea gigas. However, OsHV-1 and its variants have a 
      broad host range and can infect at least 7 bivalve species, including bay 
      scallops Argopecten irradians and eastern oysters C. virginica. Determining the 
      susceptibility of economically and ecologically important bivalve species to 
      OsHV-1 is critical for improving biosecurity and disease management to protect 
      the aquaculture industry. Surveys of eastern oysters were conducted in June to 
      August 2021 in the Maryland portion of the Chesapeake Bay to determine the 
      prevalence and viral load of OsHV-1 at 5 aquaculture farms. Using quantitative 
      PCR, OsHV-1 was not detected at any sites. Experiments examined the 
      susceptibility of single stocks of eastern oysters and hard clams Mercenaria 
      mercenaria to the virus and their ability to horizontally transmit it using 
      OsHV-1 microVar SD (San Diego, California) and OsHV-1 microVar FRA (Marennes-Olreon, 
      France). Results showed that OsHV-1 microVars did not cause mortality or symptomatic 
      infection in the single stocks of eastern oysters and hard clams used in these 
      experiments using natural infection pathways. However, the eastern oyster stock, 
      when injected with OsHV-1, did transmit the virus to naive Pacific oysters. 
      Further experimentation using additional stocks and lines and establishment of 
      surveillance programs along the east and Gulf coasts of the USA are necessary to 
      prepare for the potential spread and impact of OsHV-1 related disease.
