“…Pentastomids found were either preserved in 70% alcohol or mounted on slides and treated with Hoyer's mounting medium. Pentastomid identification was based on the hook and copulatory spiculae dimensions of the males (measured with the aid of an optical microscope fitted with a micrometer eyepiece) (Ali et al, 1984;1985;Almeida et al, 2008b).…”

Pulmonary parasitism by pentastomids was examined in two lizard species inhabiting an area of restinga vegetation (coastal sand dunes) situated in the municipality of Mataraca (6° 29' S and 34° 56' W), on the extreme northern coast of Paraíba State, Brazil. A total of 123 lizards were collected, being 75 specimens of Micrablepharus maximiliani (Gymnophtalmidae) and 48 specimens of Cnemidophorus ocellifer (Teiidae). Only a single species of Pentastomida (Raillietiella mottae) was found parasitizing three females M. maximiliani, with a prevalence of 4% and an average infection intensity of 2.3 ± 1.3 (range 1-5). The infection rate by pentastomids encountered in the present study was similar to that seen with other species of restinga lizards. Raillietiella mottae is a generalist parasite species that is probably transmitted by common and widely distributed insects making up part of the diet of many insectivorous lizard species from northeastern Brazil.Keywords: parasitism, lizards, Neotropical region. Infecção pulmonar por pentastomídeos em lagartos de restinga do nordeste brasileiroResumo O parasitismo por pentastomídeos foi estudado em duas espécies de lagartos de restinga no Nordeste brasileiro Foram realizadas coletas no município de Mataraca (6° 29' S e 34° 56' W), extremo norte do litoral do Estado da Paraíba. Foram coletados 123 lagartos, 75 Micrablepharus maximiliani (Gymnophtalmidae) e 48 Cnemidophorus ocellifer (Teiidae). Apenas uma única espécie de Pentastomida, Raillietiella mottae, foi encontrada parasitando três fêmeas de M. maximiliani, com prevalência de 4% e intensidade média de infecção de 2,3 ± 1,3 (amplitude 1-5). Os dados de prevalência encontrados são relativamente semelhantes aos de outras espécies de lagartos de restinga parasitados por pentastomídeos. Raillietiella mottae é uma espécie de parasita generalista e deve ser transmitida por insetos comuns e de ampla distribuição geográfica presentes na dieta de várias espécies de lagartos insetívoros no Nordeste brasileiro.Palavras-chave: parasitismo, lagartos, região Neotropical.

“…The pentastomids collected were cleared in Hoyer's medium, temporarily slide-mounted and preserved in ethanol 70%. Identification was performed based on dimensions of the hooks and copulatory spiculae of males, with the aid of a microscope with a micrometric eyepiece (see Ali et al, 1984;1985;Almeida et al, 2008b).…”

“…The pentastomids that were found were cleared in Hoyer's medium, temporarily slidemounted and preserved in ethanol 70%. Identification was based on the dimensions of the hooks and male copulatory spicules (see Rego, 1983;1984;Ali et al, 1984a;1984b;1985). During the identification of the individuals we also compared the specimens with material from the Helminthological Collection of the Instituto Oswaldo Cruz (CHIOC): C. tetrapoda (CHIOC 29185a-d, 29190a-l), R. furcocerca (CHIOC 31899a-c); and with material from the Coleção Zoológica da Universidade Regional do Cariri (LZ-URCA): C. tetrapoda (LZ-URCA 0043-0044; 0157-167) and R. furcocerca (LZ-URCA 168-170a-e).…”

Pentastomid infection in Philodryas nattereri Steindachner, 1870 and Oxybelis aeneus (Wagler, 1824) (Squamata: Colubridae) in a caatinga of northeastern Brazil

The relationship between pentastomids and two Colubridae species, Phillodryas nattereri Steindachner, 1870 and Oxybelis aeneus (Wagler, 1824), were investigated in the federal government's reserve Estação Ecológica do Seridó (ESEC, Seridó) situated at lat 6° 35'-40' S and long 37° 15'-20 W in the municipality of Serra Negra do Norte, state of Rio Grande do Norte, Northeast Brazil and run by IBAMA (the Brazilian Institute for the Environment and Natural Resources). Throughout 2005, 26 specimens of snakes, 13 of P. nattereri and 13 of O. aeneus were collected. After anatomical dissection and laboratorial examination of the snakes' respiratory tracts, P. nattereri was found to be parasitized by two species of pentastomids: Cephalobaena tetrapoda Heymons, 1922 with a prevalence of 30.8% and a mean intensity of infection of 51.5 ± 32.7 (range 3-147), and Raillietiella furcocerca (Diesing, 1863) which had a prevalence of 7.7% and a mean intensity of infection of 1.0. Only one female of O. aeneus was found to be infected by C. tetrapoda, with a prevalence of 7.7% and mean intensity of infection of 2.0. There was no significant relationship between size of snout-vent length (SVL) and intensity of infection in the specimens investigated here. The two individuals of P. nattereri infected by more than 40 specimens of pentastomids had their lungs completely infected including the pulmonary peritoneum and trachea. It is noteworthy that the hosts had their lung tissues partially destroyed with apparent haemorrhage, and the trabecular structure of their lungs was also destroyed. The contrasting rates of infection estimated here may be related to differences in foraging strategies, in diet, and habitat selection carried out by individuals of P. nattereri and O. aeneus.Keywords: Endoparasites, Cephalobaena, Raillietiella, neotropical region.
