          Abstract

          This study aimed to evaluate the infection rates of snakes by pentastomids in the semi-arid region of Brazil. Fifteen snakes (four Micrurus ibiboboca (Merrem, 1820) and eleven Philodryas nattereri Steindachner, 1870) were collected between January and April of 2005, in the municipality of Crato (07° 14' S and 39° 24' W), State of Ceará, Brazil. Laboratorial analysis of the respiratory tracts of the sampled snakes indicated differences in host infection rates: four individuals of P. nattereri (36.4%) were infected by Cephalobaena tetrapoda Heymons, 1922 (mean infection intensity 1.5 ± 0.28, 1-2) and three specimens (27.3%) by Raillietiella furcocerca (Diesing, 1863) (2.3 ± 1.32, 1-5). Only one individual of M. ibiboboca (25%) was infected by a non-identified species of Raillietiella sp. These are the first data on pentastomid infection in snakes in Northeastern Brazil and both snake species comprise new host records for the pentastomids. The results also indicate that the generalist parasites C. tetrapoda and R. furcocerca share their definitive hosts.

          Este artigo visou compreender as taxas de infecção por pentastomídeos em serpentes na região do semi-árido brasileiro. Quinze serpentes (quatro Micrurus ibiboboca (Merrem, 1820) e onze Philodryas nattereri Steindachner, 1870) foram coletadas entre os meses de janeiro e abril de 2005, no município do Crato (07° 14' S and 39° 24' W), Estado do Ceará. A análise laboratorial do trato respiratório das serpentes amostradas indicou diferenças nas taxas de infecção: quatro indivíduos de P. nattereri (36.4%) estavam infectados por Cephalobaena tetrapoda Heymons, 1922 (intensidade de infecção média de 1.5 ± 0.28, 1-2) e três (27.3%) por Raillietiella furcocerca (Diesing, 1863) (2.3 ± 1.32, 1-5). Apenas um indivíduo de M. ibiboboca (25%) estava infectado por uma espécie não identificada de Raillietiella sp. Essas informações constituem os primeiros dados sobre infecção por pentastomídeos em serpentes para a região do nordeste brasileiro e ambas as espécies de serpentes constituem novos hospedeiros para os pentastomídeos identificados. Os resultados também indicam que os parasitas generalistas C. tetrapoda e R. furcocerca compartilham seus hospedeiros definitivos.
