Abstract

Abstract:

To investigate the prevalence of Angiostrongylus cantonensis infection in Achatina fulica in a wetland park of Haikou, A. fulica were randomly collected from a public green land and underneath the ripraps of the wetland park during March to July of 2021 and 2022. A. cantonensis infection among the A. fulica was determined by lung examination. A. cantonensis rRNA gene was amplified by PCR and the sequence was compared by BLAST analysis. The result suggested 23 of 207 (11.11%) A. fulica were infected with A. cantonensis. The amplified 400 bp-DNA sequence was close to the reference sequences of A. cantonensis in the NCBI GenBank (Accession number: AY295821.1, FM207759.1, AM039758.1 and ON747308.1). The sequence similarity ranged from 98.49% to 99.75%. In conclusion, A. cantonensis were found in A. fulica collected from the wetland park of Haikou. This will be provide a infection risk upon touching or eating the raw or partially cooked A. fulica.

Key words: Achatina fulica, Angiostrongylus cantonensis, Lung examination method
