Table 1 Vibrio parahaemolyticus mean colony forming units (CFU) per millilitre (ml) from the three experimental bacterial culture setups MgSO4·7H2O (NONE), MgSO4·7H2O with commercial chitin [CHITIN (0.05gm/3 ml)], and MgSO4·7H2O with carapace [CARAPACE (0.05gm/3 ml)]

From: Host, pathogen and environment: a bacterial gbpA gene expression study in response to magnesium environment and presence of prawn carapace and commercial chitin
