The Vibrio spp. were used in the test.
The bacteria were used in this test were Vibrio spp., which were isolated from the diseased shrimp which were collected from some provinces in Thailand, such as Chanthaburi, Rayong, Prachinburi, Chachengsao, Bangkok, Phetchaburi, Prajub, Chumporn, Ranong, Krabi, Nakornsrithammarat, Trang, and Patani. They were identified as Vibrio alginolyticus, Vibrio cholaere, Vibrio damsela, Vibrio fluvialis, Vibrio harveyi , Vibrio parahaemolyticus Vibrio vulnificus and Vibrio spp. with the API 20NE (Geiss,H.K. et. al. 1985). The bacteria were stocked in Thiosulfate citrate bile salt sucrose (TCBS) at ambient room temperature, during the experiments.The chitosan was used in the test.The chitosan was obtained from the shrimp shop and was sent to check the purity at Department of Fishery Product, Faculty of Fisheries, Kasetsart University, Thailand. The results showed that, the chitosan concentration is 3.63 percent at the pH 4.57 by the method of turbidimeter A.O.A.C (1984).
