“…The pentastomids found were either preserved in ethanol 70% or mounted on slides and treated with a Hoyer medium. Their identification was based on the dimension of hooks and the copulatory spicules of males (Rego, 1983;1984;Ali et al, 1981;1984a, b, 1985. The specimens found were compared with representative material from two collections: the Helminthological Collection of the Instituto Oswaldo Cruz (CHIOC) and the Zoological Collection of the Laboratory of the Universidade Regional do Cariri (LZ-URCA) in order to confirm parasite identity: Raillietiella freitasi (CHIOC 20420, 20421, 20429, 20431, 20432, 20434, 20439, 30325a-c, 30326, 30327, 30328, 30329a-c, 30330a-b) and R. mottae (LZ-URCA 0201-212).…”

From January to April 2006, 37 specimens of Hemidactylus mabouia were collected in houses, in the municipality of Barbalha (7° 20' S and 39° 18' W), Ceará State, Northeast Brazil. Among the individuals captured, 17 were infected with pentastomids, totalling a prevalence of 45.9%, which did not differ between sexes. Host size did not influence the infection intensity. Two species of pentastomids were found: Raillietiella frenatus and R. mottae. The prevalence of R. frenatus (43.2%) was higher than R. mottae (2.7%), whereas the infection intensity of R. frenatus was comparatively lower (1.8 1.4) than R. mottae (36 parasites in a single host). Overall mean intensity of infection was 3.8 8.4 pentastomids. We found no pentastomid infecting juvenile geckos. The parameters of infection in this host population are in accordance to the findings of other studies, in which the high parasitism rate was associated to the feeding habits of geckos living in houses and buildings. Hemidactylus mabouia is a new host to R. mottae and the infection by R. frenatus is the first record of the occurrence this pentastomid species in Brazil.Keywords: Raillietiella, Pentastomida, house geckos, neotropical region. Pentastomídeos infectando um lagarto invasor, Hemidactylus mabouia (Gekkonidae), na região nordeste do Brasil ResumoDe janeiro a abril de 2006 foram coletados 37 espécimes de Hemidactylus mabouia em domicílios no município de Barbalha (7° 20' S e 39° 18' W), Estado do Ceará, Nordeste do Brasil. Entre os indivíduos capturados, 17 estavam infectados com pentastomídeos, totalizando uma prevalência de 45,9%, sem diferenças significantes entre os sexos. O tamanho dos hospedeiros também não influenciou na intensidade de infecção. Duas espécies de pentastomídeos foram encontradas: Raillietiella frenatus e R. mottae. A prevalência de R. frenatus (43,2%) foi mais alta do que a de R. mottae (2,7%), enquanto que a intensidade média de infecção de R. frenatus foi comparativamente mais baixa (1.8 1.4) do que a de R. mottae (36 parasitas em um único indivíduo). A intensidade geral de infecção foi de 3.8 8.4 pentastomídeos. Não foi encontrado nenhum gecko juvenil infectado por pentastomídeo. Os parâmetros de infecção nesta população de hospedeiros estão de acordo com outros estudos, que indicam altas taxas de parasitismo associadas com os hábitos alimentares de geckos vivendo em domicílios e edificações. Hemidactylus mabouia representa um novo hospedeiro para R. mottae e a infecção por R. frenatus constitui o primeiro registro de ocorrência desta espécie de pentastomídeo no Brasil.

“…There is also the possibility that the exotic pentastomid R. frenatus is specific for H. mabouia. Other investigations suggest that exotic geckos retained their natural pentastomid fauna (Self and Diaz, 1961;Ali et al, 1981;Ali and Riley, 1983;Pence and Selcer, 1988;Riley et al, 1988;1991). These exotic pentastomids appear to have been able to colonize intermediate hosts having wide geographic distributions, such as the cockroach, Periplaneta americana (Ali and Riley, 1983;Jeffery et al, 1985;Bosch, 1986;Criscione and Font, 2001).…”

“…The 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 dimensions of the hooks and copulatory spiculae of the males (measured with the aid of a microscope fitted with a micrometer eyepiece) (Ali et al, 1981). Drawings were made with the aid of a drawing tube connected to a brightfield microscope.…”

The rates of pentastomid infections in the syntopic lizards Hemidactylus mabouia and Tropidurus hispidus inhabiting buildings at the Federal University of Paraiba, in João Pessoa, NE Brazil were examined. A total of 30 specimens of Hemidactylus mabouia and 55 specimens of Tropidurus hispidus were examined. The animals were sacrificed by freezing and then fixed and conserved in 70% alcohol. Analyses of the respiratory tract of Hemidactylus mabouia demonstrated that these lizards were infected by Raillietiella frenatus at a rate of 20% (6/30) with an average infection intensity of 1.33 ± 0.21, 1-2. None of the specimens of T. hispidus analyzed were infected. Hemidactylus mabouia and R. frenatus are of African origin and it is possible that there are specific relationships, or preferences, between these two species.Keywords: parasitism, house geckos, neotropical region. Hemidactylus mabouia e R. frenatus possuem origem africana e é possível que haja alguma relação de especificidade ou preferência entre essas espécies.

“…Interestingly, they explicitly referred to some Indian material in the London Natural History Museum recovered from the garden lizard Calotes versicolor which was identified by Richard Heymons as R. geckonis, but which Ali et al (1981) had previously reidentified as Raillietiella hemidactyli Hett, 1934. The Berlin specimens were not explicitly mentioned by Ali et al (1981Ali et al ( , 1982a, but clearly share the same locality and host data, originate from London and were expliticly identified by Heymons as R. geckonis: "det R. Heymons". We know that there was an exchange of material between Heymons and London and thus we strongly suspect that ZMB 48027-28 are part of the same series, the London examples of which were reidentified by Ali et al (1981).…”
