Abstract The present study investigated some helminth parasites infecting some reptilian species inhabiting the South Sinai desert, Egypt. Lizards were collected from January to September 2018. The collected lizard species were ocellated skink Chalcides ocellatus, white-spotted gecko Tarentola annularis, and rainbow skink Mabuya quinquetaeniata. The prevalence of parasitic infections (nematodes) among the examined lizard species was studied. Different three Nematoda species were recorded; these were Thelandros chalcidiae sp. nov., Spauligodon aspiculus Khera (1961), Pharyngodon mamillatus Linstow (1897). The present investigation of parasitic infections was carried out using morphological and morphometric characterizations by using light and scanning electron microscopy. In addition, molecular analyses of 28S rRNA gene sequences for two of the recovered nematodes and their phylogenetic relationships were applied to detect their exact taxonomy. |
