Comparison of morphological and anatomical characteristics of Biomphalaria straminea of intermediate hosts of Schistosoma mansoni and several species of Planorbidae
摘要
Abstract
The four Planorbidae species are intermediate hosts of Trematoda and Nematoda, and the invasive spe-cies Biomphalaria straminea is an intermediate host of Schistosoma mansoni.Due to reports that the shell charac-teristics of these species are closely similar to each other and the taxonomic data of these species are incomplete, comparing the shell, radulae, and reproductive system of the four Planorbidae species can provide the basis of ac-curate identification of these species for Sanitation and Anti-epidemic Department. In this study, the electronic digital caliper was used to; measure the shells parameters of all the samples, dissect and draw the reproductive sys-tem of the four Planorbidae species, and observe the morphology of radula by electron microscopy. The analysis of variance (ANOVA) showed that the mean ratios between the height (H) and diameter (D) of the shell (H/D) of the four species of Planorbidae were significantly different (F = 64.171, P <0.01). All of the radula of the four species of Planorbidae have one central tooth with two other sharp teeth, but the shape of the central tooth, the number of columns of lateral tooth and marginal tooth, and the shape and number of sharp teeth are different in each species, which is one of the important species identification features. There were significant differences in the structure of the penile complex of the reproductive system at the Genus level but they were similar in the interspecies level (Gyraulus convexiusculus and Gyraulus parvus). Although the morphology of the shells in the four Planorbidae species is similar, the mean ratios between the height (H) and diameter (D) of the shell, the number of columns and structure of radula, and the structure of penial complex of the reproductive system have important value for accurate identification of invasive species Biomphalaria straminea and several common Planorbidae species in China.关键词
