Checklist of parasites associated with ʻreptiles’ in Northeast Brazil

Abstract

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.

Oswaldocruzia franciscoensis n. sp. (Nematoda: Molineidae) in Leptodactylus macrosternum Miranda-Ribeiro, 1926 (Anura: Leptodactylidae) from Caatinga morphoclimatic domain, Brazil: morphological and molecular characterisation

“…Oswaldocruzia Travassos, 1917 (Nematoda: Molineidae) comprises about 90 nominal species of parasites from amphibians and reptiles distributed worldwide (Guerrero 2013; Svitin 2017; Willkens et al 2021). Currently, 43 species have been reported in the Neotropical region (Willkens et al 2021), in which 11 are widely distributed in Brazil, infecting several species of amphibians and lizards (see Lent and Freitas 1935; Freitas and Lent 1938; Ben Slimane and Durette-Desset 1995; Bursey and Goldberg 2004, 2011; Durette-Desset et al 2006; Ávila and Silva 2010; Campião et al 2014; Larrat et al 2018; Benício et al 2022; Lacerda et al 2023). Although species of Oswaldocruzia from Brazil frequently appear in studies of species inventory or parasite ecology, most taxonomic studies regarding morphological descriptions have been published before the last 20 years (Bursey and Goldberg 2004; Durette-Desset et al 2006; Santos et al 2008; Larrat et al .…”
