Abstract

Genetic relationship between Perkinsus in China's offshore shellfish.

Abstract

The distribution and classification of Perkinsus spp. in China's offshore shellfish were studied. Thirty different kinds of major economic shellfish from fifty-eight locations in nine coastal provinces of China from north to south such as Liaoning, Hebei, Guangxi, Hainan, was sampled and analyzed. PCR was applied to amplify the rDNA-ITS sequences, and thus the species and their distribution of Perkinsus spp. was preliminarily identified. The results indicated that China has two different kinds of Perkinsus spp. and the differences in rDNA-ITS sequences are large. These two different Perkinsus sp. are respectively P. olseni detected from Ruditapes philippinarum, Mytilus, Scapharca subcrenata, Haliotis discus hannai and Oysters, and P. beihaisens detected from Crassostrea rivularis living in Southern China.
