Abstract
Taenia saginata is the most common human Taenia in Thailand. By cox1 sequences,
73 isolates from four localities in north and northeast were differentiated into
14 haplotypes, 11 variation sites and haplotype diversity of 0.683. Among 14
haplotypes, haplotype A was the major (52.1%), followed by haplotype B (21.9%).
Clustering diagram of Thai and GenBank sequences indicated mixed phylogeny among
localities. By MJ analysis, haplotype clustering relationships showed
paired-stars-like network, having two main cores surrounded by minor haplotypes.
Tajima's D values were significantly negative in T. saginata world population,
suggesting population expansion. Significant Fu's F s values in Thai, as well as
world population, also indicate that population is expanding and may be
hitchhiking as part of selective sweep. Haplotype B and its dispersion were only
found in populations from Thailand. Haplotype B may evolve and ultimately become
an ancestor of future populations in Thailand. Haplotype A seems to be dispersion
haplotype, not just in Thailand, but worldwide. High genetic T. saginata
intraspecies divergence was found, in contrast to its sister species, T.
asiatica; among 30 samples from seven countries, its haplotype diversity was
0.067, while only 2 haplotypes were revealed. This extremely low intraspecific
variation suggests that T. asiatica could be an endangered species.
