TI  - Histological Alterations in Pacific Oysters Crassostrea gigas that Survived a 
      Summer Mortality Event in Baja California, Mexico.

AB  - A mortality episode (>90%) of triploid and diploid Pacific oysters Crassostrea 
      gigas cultured in Baja California Sur occurred during summer 2012, coinciding 
      with a thermal anomaly, an algal bloom, and low oxygen values. To help explain 
      the cause of the mortalities, histological analyses and molecular tests for 
      specific pathogens (ostreid herpesvirus 1 [OsHV-1] and Perkinsus marinus) were 
      performed on oysters surviving at the end of the episode. Triploid oysters showed 
      a high percentage of males (43%) and hermaphrodites (30%); 93% of these oysters 
      were in the gonadic reabsorption stage, and in some cases, hemocytes completely 
      filled the lumen of the gonadic follicles. Oysters presented large areas with 
      severe hemocyte infiltration that extended toward the digestive gland. Diploid 
      oysters showed similar gonad alterations. None of samples showed histological or 
      molecular evidence of OsHV-1 or P. marinus. Histological alterations can be 
      related to physiological disorders caused by the mechanism driving summer 
      mortality. This is the first case history of a summer mortality episode among 
      Pacific oysters in Mexico.
