The genetic variation of Angiostrongylus cantonensis in the People's Republic of China.

ABSTRACT:

Background

The People's Republic of China (P.R. China) is the presumptive home range of the rat lungworm Angiostrongylus cantonensis, a major aetiological agent of human eosinophilic meningitis. We present a study of the genetic variation of A. cantonensis in P.R. China. Our aim was to deepen the current knowledge pertaining to its origin and global spread from a molecular perspective.

Methods

Adult A. cantonensis were collected in the frame of a national survey and identified based on morphological criteria. Polymerase chain reaction (PCR) was employed to amplify the target DNA sequences (cytochrome c oxidase subunit I (cox1), nicotinamide adenine dinucleotide dehydrogenase subunit 1 (nad1) and internal transcribed spacer (ITS)). The PCR product of cox1 was directly submitt
