| Abstract | ||||
| Background: Despite the fact that Egypt contains a large number of lizard species, yet there is little knowledge recorded regarding the helminth fauna infecting this group of hosts. A parasitological study on gastrointestinal helminths of lizards was carried out during Summer (August) and Autumn (September and October), 2014 and 2015, respectively. Objective: This study aims to update information on helminth parasites that infect lizards in Egypt. Material and Methods: Seven species of lizards, Pseudotrapelus sinaitus Heyden, 1827; Trapelus mutabilis Merrem, 1820 (Agamidae); Tarentola mauritanica mauritanica Linnaeus, 1758 (Phyllodactylidae); Tropiocolotes tripolitanus Peters, 1880 (Gekkonidae); Acanthodactylus boskianus Daudin, 1802 (Lacertidae); Chamaeleo africanus Laurenti, 1768 (Chamaeleonidae); and Varanus niloticus Linnaeus, 1766 (Varanidae), were collected from several parts of Egypt. These hosts were dissected and examined for gastrointestinal helminth. The collected helminths were fixed in 70% ethanol, stained with carmine and examined by using an Olympus CX31 microscope and a Zeiss Stemi 2000-C microscope. Results: The total prevalence of infection with helminths was 35.9%. The study recorded 16 species of helminths recognised as: six species of digenea [Prosthodendrium obtusum (Looss, 1896) Bhalerao, 1936, Pleurogenoides tener (Olsson, 1876) Travassos, 1921, Anchitrema sanguineum (Sonsino, 1894) Looss, 1899, Cyclorchis varani Price, 1936, Mesostephanus milvi Yamaguti, 1939 and Haplorchis pumilio (Looss, 1896) Looss, 1899], four species of cestodes [three adults, Oochostrica mutabili Morsyet al., 2013, Duthiersia fimbriata Diesing, 1854 and one unidentified cestode and one tetrathyridia of Mesocestoides spp.] and six species of nematodes [Parapharyngodon micipsae Seurat, 1917, Pharyngodon inermicauda Baylis, 1923, Abbreviata leptosome Gervais, 1848, Thubunaea pudica Seurat, 1914, Tanqua tiara (von Linstow, 1879) Blanchard, 1904 and Spinicauda sonsinoi (Linstow, 1894) Travassos, 1920]. Conclusion: This study documents 10 new host and 10 new locality records in Egypt and distinguishes between studied material and reported descriptions. These findings add significantly to the present information on helminths infecting lizards in Egypt. | ||||
