“…Norops fuscoauratus (D'Orbigny in Duméril & Bibron, 1837), a small-bodied lizard of the family Dactyloidae, has a disjunct geographic distribution in the Amazon and the Atlantic Forest, with populations in highland marshes in the Brazilian state of Ceará (Avila-Pires, 1995; Loebmann & Haddad, 2010; Ribeiro-Junior, 2015). Biological aspects of N. fuscoauratus have been published, such as diet and microhabitat use (Vitt et al ., 2003, 2008), whereas parasitological studies are more scarce and restricted to Amazonian populations (Ávila & Silva, 2010, 2013). Herein, we present the parasitological descriptors of helminths associated with N. fuscoauratus from highland marshes of the Brazilian semi-arid, testing the influence of host body size on parasitism.…”

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.

“…Coleodactylus meridionalis is a small lizard, and in the present study obeys the standards already described in the literature, with low parasite richness; this is commonly represented by the following lizards: Anotosaura vanzolinia Dixon, 1974 (Squamata: Gymnophthalmidae) with an average SVL of 36 mm; Liolaemus lutzae Mertens, 1938 (Squamata: Liolaemidae), 50 mm of SVL; Aspronema dorsivittatum (Cope, 1862) (Squamata: Scincidae) 64 mm of SVL; Phyllopezus lutzae (Loveridge, 1941) (Squamata: Phyllodactylidae) 42 mm of SVL and Dryadosaura nordestina Rodrigues, Xavier Freire, Machado Pellegrine and Sites, 2005 (Squamata: Gymnophthalmidae) 40 mm of SVL, which harbor up to three parasite species Oliveira et al, 2017;Rocha, 1995;Rocha et al, 2003;Teixeira et al, 2018b). This pattern may be explained by specific sites of infection only being available within larger hosts due to potential greater niche heterogeneity, which thus facilitates segregation of microhabitats (Kuris et al, 1980).…”

Summary Studies that seek to understand which factors influence the patterns of infection in the lizard Coleodactylus meridionalis are non-existent. In this way, we recorded the infection rates for these lizards from three different sized fragments of the Atlantic rainforest and investigated if there is influence of the size, mass and sex of the host regarding the endoparasite abundance. In addition, we investigated if there were possible associations between the host’s diet and parasitism, by calculating the diet niche breadth (based on the prey number of pooled stomachs) for each host population and comparing the diet between fragments and sexes (from the three sampled fragments). We collected 38 lizards across the three sampled forest fragments. We only found parasites in the lizards sampled from the smallest of the three forest fragments which included: Physaloptera lutzi, Haplometroides odhneri and Oligacanthorhynchus sp. For this population, lizards with greater length and body mass have a greater endoparasite abundance. In addition, based on the results obtained in our study, the diet of the lizards varies in food composition between sampled populations. Finally, knowing that among the infected lizards there is no sexual dimorphism in relation to size and body mass and that the stomach sampling for this population is insufficient to calculate the indexes related to the food niche; we used the number of prey lizards from all populations, thus we were able to associate the fact that female lizards have a greater endoparasite abundance due to variations in food composition between sexes.

Checklist of parasites associated with ʻreptiles’ in Northeast Brazil

et al. 2023

Reptiles, as well as other vertebrate groups, harbour a significant diversity of parasitic organisms, from nematodes and other helminths to viruses and bacteria. The Northeast is one of the richest regions in Brazil in terms of the reptile diversity, number of species and endemism. Parasites are diverse organisms and knowledge about the parasitic fauna of vertebrates is an important factor in understanding the ecological relationships between hosts and the environment. Studies on the parasitic fauna of reptiles in South America have increased in the past few years. The present review is a compilation of 122 studies published from 1924 to 2021. We present information on 101 species of reptiles from five groups (amphisbaenians, crocodile, testudines, snakes and lizards) and 183 parasitic taxa belonging to four phyla: Nematoda; Arthropoda; Platyhelminthes; and Acanthocephala. Nematodes were the most frequently recorded species. Lizards and snakes had more records of parasitism and higher levels of parasite richness and diversity. Ceará was the state with most studies and recorded cases of parasite–host association. The Caatinga and Atlantic Forest were the most investigated environments. The objective of this review was to contribute knowledge on the parasitic biodiversity in reptiles from Northeast Brazil, which may help identify gaps in our knowledge and guide future studies.
