ABSTRACT
Agama agama, the agamid rainbow lizard, has been reported to serve as transport and reservoir host to several protozoan and helminth parasites. We randomly sampled 310 specimens between May and July, 2005, at Oyingbo, Lagos, Nigeria (6°34’60’’ N-3°19’59’’ E and 6°34’60’’ N-3°19’59’’ E).They harboured four species of nematodes Strongyluris brevicaudata, Parapharyngodon awokoyai, Capillaria sp. and Oxyuris sp.; one of Cestoda, Oochoristica agamae; one of Trematoda, Mesocoelium monas; and one of Pentastomida, Raillietiella sp. Strongyluris brevicaudata had the highest prevalence of infection (82.3 %), followed by P. awokoyai (74.5 %), Raillietiella (10.3 %), Capillaria sp. (8.4 %) and O. agamae (7.4 %). M. monas and Oxyuris sp. had low prevalences 1.61 % each. Raillietiella sp. and Capillaria sp. can cause localized inflammation and intestinal infections in humans. The prevalence of infection was higher in larger adult lizards. Prevalence in males was 97.6 % (94.1 % in females). in four of the helminth species, intensity of infection was higher in male lizards. Parasite intensity was highest in the rectum, followed by the intestine (p<0.05). infection intensity was, to a large extent, dependent on the type of parasite, and age of lizard. During May, P. awokoyai had its highest mean intensities and prevalence. The prevalence and mean intensity of helminthes varied with the month of collection (both p<0.05). For the three months studied, prevalence and mean intensity of S. brevicaudata were highest in June (July for the other species). Rev. Biol. Trop. 55 (2) 417-425. Epub 2007 June, 29.
RESUMEN
La lagartija Agama agama actúa como medio de transporte y hospedero para varios protozoos y helmintos parásitos. Capturamos 310 lagartijas, muestreadas aleatoriamente, entre mayo y julio 2005, en Oyingbo, Lagos, Nigeria (6°34’60’’ N-3°19’59’’ E y 6°34’60’’ N-3°19’59’’ E). Hallamos cuatro especies de nematodos Strongyluris brevicaudata, Parapharyngodon awokoyai, Capillaria y Oxyuris; un céstodo intestinal, Oochoristica agamae; un trematodo, Mesocoelium monodi; y un pentastómido, Raillietiella. S. brevicaudata tuvo la mayor prevalencia de infección (82.26 %), seguida por P. awokoyai (74.52 %), Raillietiella (10.32 %), Capillaria (8.38 %) y O. agamae (7.41 %). M. monodi y Oxyuris tuvieron baja prevalencia con 1.61 % cada uno. Raillietiella y Capillaria causan inflamación localizada e infección intestinal en humanos. La prevalencia de infección estuvo positivamente relacionada con el tamaño de las lagartijas adultas. Los machos tuvieron mayor prevalencia, con 97.58 % (hembras 94.09 %). La infección intestinal en los machos fue mayor para cuatro de las especies de helmintos. La intensidad parasitaria fue mayor en el recto, seguida por el intestino (p<0.05). La intensidad de la infección fue dependiente del tipo de parásito y la edad de la lagartija. En mayo, P. awokoyai tuvo el mayor promedio de intensidad y prevalencia. La prevalencia y la intensidad promedio de S. brevicaudata fue mayor en junio (julio en las demás especies). La prevalencia y la intensidad variaron con el mes (ambos p<0.05).
