Longitudinal Study of Total and Pathogenic (+ and/or +) in Two Natural Extraction Areas of in Southern Chile.

is the leading cause of seafood-associated bacterial gastroenteritis worldwide. Although different studies have focused on its pattern of variation over time, knowledge about the environmental factors driving the dynamics of this pathogen, within the Chilean territory, is still lacking. This study determined the prevalence of total and pathogenic strains ( and/or genes) in mussels () collected from two natural growing areas between 2017 and 2018, using selective agar and PCR analysis.

Uptake and retention of Vibrio parahaemolyticus in a cohabitating population of Ruditapes decussatus and Ruditapes philippinarum under experimental conditions.

The presence of Vibrio parahaemolyticus in bivalve mollusc is an important cause of foodborne illnesses, and their levels are influenced by environmental changes, such as temperature and salinity. Clams are common species in estuaries and are used in environmental monitoring programmes. Present study compared the uptake and retention of nonpathogenic V.
