“…In the present study its prevalence of 2.5% is inferior to its reported infection levels in Hemidactylus mabouia (Moreau de Jonnès, 1818) (2.7%), Phyllopesus pollicaris (Spix, 1825) (16.6%), P. periosus Rodrigues, 1986 (66.7%), T. hispidus (11.1%) and T. semitaeniatus (13.3%) in other areas from northeastern Brazilian (Almeida et al, 2008a;2008b;Anjos et al, 2007;2008) (Table 1).

“…Nevertheless, the prevalence of Raillietiella spp. in lizards from Caatinga region (present study; Anjos et al, 2007;2008;Almeida et al, 2008a;2008b) were greater than that recorded for some lizard species in Restinga habitats (coastal sandy dune habitats) (Table 1) 1823 (3.6-9.0%, Vrcibradic et al, 2002b); the Teiidae hosts Cnemidophorus ocellifer (Spix, 1825) (2.5%, Dias et al, 2005) and C. abaetensis Dias, Rocha andVrcibradic, 2002 (6.0%, Dias et al, 2005), and the Gymnophtalmidae Micrablepharus maximiliani (Reinhardt and Luetken, 1862) (4.0%, Almeida et al, 2009). …”

“…The absence of these parasites in the lungs of T. semitaeniatus in the present study may simply be related to the low numbers of that host sampled. These two lizard species share similar feeding resources and microhabitats (Vanzolini et al, 1980;Vitt, 1995), which would otherwise favor the acquisition of a similar parasite fauna (see Almeida et al, 2008b).…”

“…Although most of the studies of parasitism in vertebrates are mainly concerned with economic questions , ecological studies focusing interactions between parasites and their lizard hosts have been relatively well documented in Brazil over the last two decades (Ribas et al, 1995(Ribas et al, , 1998Rocha, 1995;Vrcibradic et al, 1999;2002a, b, 2007Bursey et al, 2003;Dias et al, 2005;Anjos et al, 2005Anjos et al, , 20072008;Goldberg et al, 2006;Almeida et al, 2008aAlmeida et al, , 2008bAlmeida et al, , 2009.…”

“…Pentastomids have been relatively poorly studied in the Neotropical region, despite its importance as a parasite of vertebrate (Almeida and Christoffersen, 2002). However, the recent reports of parasite occurrence, the new species descriptions, and the information concerning new host records have added knowledge on pentastomid-lizard interactions (Vrcibradic et al, 2002a;Dias et al, 2005;Anjos et al, 2007;2008;Almeida et al, 2008a;2008b;2009). On the other hand, reports concerning lung infections by Rhabdias have been relatively less frequent -and only an infection in the lizard Enyalius bilineatus (Duméril and Bibron, 1837) (Leiosaurinae) from an area of Atlantic Rainforest in Espírito Santo state, southeastern Brazil (Vrcibradic et al, 2007) and an infection of Norops fuscoauratus (d'Orbingy, 1837) (Polychrotidae) in northern Brazil (Goldberg et al, 2006) have been previously reported.…”

We present data on pulmonary infection rates by parasites in the lizards Tropidurus hispidus Spix, 1825 and T. semitaeniatus (Spix, 1825) living sympatrically in the Chapada do Araripe mountain Range, northeastern Brazil. We found no parasite pulmonary infection in T. semitaeniatus. However, two pulmonary parasite species were found in the T. hispidus hosts, the pentastomid Raillietiella mottae Almeida, Freire and Lopes, 2008 and the nematode Rhabdias sp. Overall prevalence was 5%. Prevalence of R. mottae was 2.5% and corresponded to only one parasite on each infected host. Prevalence of Rhabdias sp. was 2.5% and the range of infection was 1-2 parasites per host. This represents the first record of Rhabdias infecting lizards of the family Tropiduridae in the Neotropical region. Furthermore, we present a comparison of parameters of infection by pulmonary parasites including some recent studies in Brazil.Keywords: Raillietiella, Rhabdias, Pentastomida, neotropical region. Taxas de infecção pulmonar em duas espécies simpátricas de lagartos Tropiduridae por pentastomídeos e nematódeos na região Nordeste do Brasil ResumoApresentamos dados sobre taxas de infecção pulmonar por parasitas nos lagartos Tropidurus hispidus e T. semitaeniatus que vivem simpatricamente na encosta da Chapada do Araripe, situada na região Nordeste do Brasil. Não encontramos infecção parasitária nos pulmões dos espécimes de T. semitaeniatus. Entretanto, foram encontradas duas espécies de parasitas nos hospedeiros T. hispidus, os pentastomídeos Raillietiella mottae e os nematódeos Rhabdias sp. A prevalência geral de infecção foi de 5%. A prevalência de infecção de R. mottae foi de 2,5% correspondendo a apenas um parasita por hospedeiro. A prevalência de infecção de Rhabdias sp. foi de 2,5% e a amplitude de infecção de 1-2 parasitas por hospedeiros. Esses resultados compreendem o primeiro registro de Rhabdias infectando lagartos da família Tropiduridae em toda a região Neotropical. Apresentamos também uma comparação com os parâmetros de infecção pulmonar por parasitas incluindo os estudos mais recentes no Brasil.Palavras-chave: Raillietiella, Rhabdias, Pentastomida, região neotropical.

Gastrointestinal nematodes of the lizardTropidurus hispidus(Squamata: Tropiduridae) from a semi-arid region of north-eastern Brazil

The tropidurid lizard Tropidurus hispidus has a wide distribution in South America. However, knowledge about its helminth fauna is patchy and has been reported for only a few localities along its range of distribution. This study presents data on helminth fauna composition and parameters of infection for a population of T. hispidus from an area within the Brazilian Caatinga biome (semi-arid physiognomy). We found five nematode species within the gastrointestinal tract of lizards: Parapharyngodon sceleratus (Pharyngodonidae); Physaloptera lutzi, Physaloptera retusa and Physalopteroides venancioi (Physalopteridae); and Strongyluris oscari (Heterakidae). The overall prevalence was 84.2% and the mean intensity of infection was 8.5 ± 1.1. The body size of adult male lizards influenced positively the intensity of infection. The infracommunities of nematodes presented an intermediate aggregated distribution (discrepancy index; D= 0.519) and a depauperate nematode fauna. The presence of generalist parasite species has contributed to an increase in the overall richness of the component community. This sampled host population presented the highest prevalence of parasites compared with other studies on T. hispidus, but their relatively low richness can be related to the disturbed environment of the study area.
