COMPONENT COMMUNITY OF THE PARASITIC METAZOANS OF THE AFRO-AMERICAN HOUSE GECKO HEMIDACTYLUS MABOUIA (MOREAU DE JONNÈS, 1818) (SQUAMATA: GEKKONIDAE) FROM THE JUNGLE OF PERU

 

COMPONENTE COMUNITARIO DE LOS METAZOOS PARÁSITOS DEL GECKO-CASERO TROPICAL HEMIDACTYLUS MABOUIA (MOREAU DE JONNÈS, 1818) (SQUAMATA: GEKKONIDAE) DE LA SELVA DEL PERÚ

The purpose of this study was to evaluate the component community of the parasitic metazoans of the Afro-American house gecko Hemidactylus mabouia (Moreau de Jonnès, 1818) from the jungle of Peru. Ninety-one specimens of H. mabouia from seven localities of San Martín and Huánuco were collected from April to June 2015. The parasites were collected and processed according to standard protocols. Eighty-five percent of the geckos were infected with at least one parasite species and a total of 1,120 parasite specimens were collected with a prevalence of 90%. The parasitic fauna of H. mabouia was composed of 11 species, as follow: six species of nematodes - Oswaldocruzia aff. brasiliensis Lent et Freitas, 1935, Spauligodon sp. Skrjabin, Schikhobalova & Lagodovskaja, 1960, Parapharyngodon sp. Chatterji, 1933, Physaloptera sp. Rudolphi, 1819, Acuariidae gen. sp. Railliet, Henry & Sisoff, 1912, and one species not identified of nematode; one cestode species - Oochoristica vanzolinii Rego & Rodrigues, 1965; two trematode species - Paradistomum sp.1 Kossack, 1910, Paradistomum sp.2 Kossack, 1910; one pentastomid species - Raillietiella hebitihamata Self & Kuntz, 1960; and one mite species - Geckobia hemidactyli Lawrence, 1936. The three parasites with the higher prevalence (P) and mean abundance (MA) were G. hemidactyli (P = 45.05%, MA = 4.16), Spauligodon sp. (P = 37.36%, MA = 2.64), and Raillietiella hebitihamata (P = 32.97%, MA = 2.3). Single and multiple parasitic infections with at least one, two, three, four, and five species of parasites were observed in 25, 35, 15, 6, and 1 hosts, respectively.

​

A positive association was observed between the prevalence of infection of R. hebitihamata and Parapharyngodon sp. with the total length (TL) of the gecko. There was also a relationship between TLof H. mabouia and MAand mean intensity of Spauligodon sp. The cestode O. vanzolinii and the pentastomid R. hebitihamata are first geographical record for Peru. Non-metric multidimensional scaling (NMDS) and the relationship between community composition and explanatory variables (host length, sex, and locality) were examined by permutational analysis of variance (PERMANOVA) applied to species abundances which showed high homogeneity among metazoan parasite communities of H. mabouia

RESUMEN

​

Se registra un caso de miasis cutánea específica, asociada a neoplasia bucal. La presentación del caso corresponde a un paciente geriátrico de sexo masculino, de 78 años de edad, procedente del distrito de Chorrillos, Lima, Perú que al momento de ser atendido en la clínica, presentaba una herida ulcerosa abierta, en el maxilar inferior derecho en la que se observó gran cantidad de larvas de diferentes estadios. El material biológico extraído de la herida del paciente fue identificado como Cochliomyia hominivorax (Coquerel, 1858) (Diptera: Calliphoridae), por las características morfológicas de la larva de tercer estadio a través de la microscopia óptica y electrónica de barrido. En este caso clínico, la presencia de C. hominivorax se vio favorecida por la lesión bucal del paciente que permitió atraer a las moscas para que coloquen sus huevos en el borde de la lesión.
