Helminths associated with Norops fuscoauratus (Squamata, Dactyloidae) in highland marshes of the Brazilian semi-arid

Abstract

Helminthological studies may contribute with valuable information on host biology and conservation. Herein, we provide new data on helminths infecting the lizard Norops fuscoauratus, testing one of the factors considered most important in parasitic ecology: host size. We analysed 25 specimens of N. fuscoauratus from three highland marshes in the Brazilian semi-arid. Eight taxa of helminths belonging to Nematoda, Trematoda and Acanthocephala were found. Physaloptera sp. showed the higher prevalence (40%), with a mean intensity of infection of 3.3 ± 1.46 (1–16) and mean abundance 1.32 ± 0.65 (0–16). Norops fuscoauratus represents four new host records for the helminths Cyrtosomum sp., Pharyngodon travassosi, Strongyloides sp. and Centrorhynchus sp. There is no relationship of host body size (P = 0.79) and mass (P = 0.50) with parasite richness. In addition, the present study contributes to the knowledge of the parasitic fauna of N. fuscoauratus and the Neotropical region.

Helminth fauna of Norops fuscoauratus (D’Orbigny, 1837) (Squamata: Dactyloidae) in the Atlantic Forest, northeastern Brazil

“…Norops fuscoauratus is appointed for second time intermediate host of Acanthocephala in Cystacanth phase (Santos Mesquita et al, 2020). In this study, these parasites were found in the body cavity and gastrointestinal organs and confirm the relationship between the site of infection in the host and the way of transmission of endoparasites.…”

Already in anoles of Murici (AL), we obtained Brito et al (2014a, b), Araújo-Filho et al (2014) for the populations from the semi-arid; Cabral et al (2018), Amorim andÁvila (2019) andSantos Mesquita et al (2020) for humid forest ("Brejos-de-altitude") and Almeida-Gomes et al (2012), Barreto-Lima et al (2012) and Teixeira et al (2020) for lizards from the Atlantic Forest. In addition to these contributions, the descriptive study by Albuquerque et al (2012) should be highlighted.…”

“…This study was conducted in the Amazon rainforest as a collaboration to investigate the helminth fauna associated with lizards, including additional research on Norops fuscoauratus as the host of the nematode Physaloptera retusa. Avila and Silva (2013), Teixeira et al (2020) andSantos Mesquita et al (2020) also present important data on parasites of this lizard.…”
