An unusual case of ectopic tungiasis with pseudoepitheliomatous hyperplasia
Provedor de dados: 55
Autores: Heukelbach,J.; Sahebali,S.; Van Marck,E.; Sabóia Moura,R.C.; Feldmeier,H.
Tungiasis is caused by the penetration of the female sand flea Tunga penetrans into the epidermis, and subsequent hypertrophy of the parasite. In most cases lesions are confined to the feet. During a cross-sectional study, an unusual case of ectopic tungiasis in the inguinal area was detected. Histological examination of tissue samples showed a remarkable pseudoepitheliomatous aspect of the epidermis. Clinical features and differential diagnoses are discussed.

Bat fly (Diptera: Streblidae) parasitism in degraded and preserved areas in a Neotropical savanna
Provedor de dados: 81
Autores: Ramalho,Daniel F; Graciolli,Gustavo; Aguiar,Ludmilla M. S.
We assessed the relationship between bat fly parasitism and habitat degradation. We used mist nets to capture 522 individuals of Carollia perspicillata and 429 individuals from eight fly species in the Brazil­ian Cerrado. Specimens were captured in degraded areas surrounding protected areas and within the protected areas. Trichobius joblingi was the most frequent parasite of Carollia perspicillata; consequently, it was analyzed in greater detail. Sex and age were not critical factors for parasitism. A robust anthropogenic influence was observed; unexpectedly, a higher prevalence and abundance of bat flies were observed in preserved areas.

Mad, bad and dangerous to know: the biochemistry, ecology and evolution of slow loris venom
Provedor de dados: 80
Autores: Nekaris,K Anne-Isola; Moore,Richard S; Rode,E Johanna; Fry,Bryan G.
Only seven types of mammals are known to be venomous, including slow lorises (Nycticebus spp.). Despite the evolutionary significance of this unique adaptation amongst Nycticebus, the structure and function of slow loris venom is only just beginning to be understood. Here we review what is known about the chemical structure of slow loris venom. Research on a handful of captive samples from three of eight slow loris species reveals that the protein within slow loris venom resembles the disulphide-bridged heterodimeric structure of Fel-d1, more commonly known as cat allergen. In a comparison of N. pygmaeus and N. coucang, 212 and 68 compounds were found, respectively. Venom is activated by combining the oil from the brachial arm gland with saliva, and can...

Polygenis (Polygenis) platensis (Jordan &amp;amp; Rothschild) (Siphonaptera: Rhopalopsyllidae, Rhopalopsyllinae), a new record in Brazil
Provedor de dados: 82
Autores: Linardi,Pedro M.; Cardoso,Valbérico de A.; Botelho,José R.; Lareschi,Marcela; Freitas,Thales O. de.
Polygenis (Polygenis) platensis s. l. (Jordan &amp;amp; Rothschild) is recorded for the first time from Brazil in the municipalities of Capão da Canoa, Tramandaí and Osório, RS. New host records for this flea include Ctenomys flamarioni (Travi) and Ctenomys minutus (De Blainville). Morphological variations were also observed among the flea specimens collected on the same species of host at the same municipality, evidencing some hybridization between the two subspecies and disabling the determination of the subspecific status. The number of known species of Brazilian Siphonaptera is now 60.

Susanlimae ianwhittingtoni gen. nov., sp. nov. (Monogenoidea: Dactylogyridae), a dweller of the gill rakers of Pseudeutropius moolenburghae (Siluriformes: Schilbeidae) from Sumatra
Provedor de dados: 103
Autores: Boeger,Walter A.; Pariselle,Antoine; Patella,Luciana.
ABSTRACT A new genus and species of Monogenoidea, Susanlimae ianwhittingtoni gen. nov., sp. nov., are proposed for dactylogyrids collected from the "Nuayang tipis", Pseudeutropius moolenburghae Weber &amp; de Beaufort, 1913, which inhabits freshwater in Sumatra. While clearly a member of a putative clade that includes Asian and African catfish parasites, S. ianwhittingtoni sp. nov. differs from most members of this clade by having a bifurcated haptor that embraces the gill rakers of its host. This haptoral morphology and mode of attachment also occur in species of Bifurcohaptor Jain, 1958. However, species of Susanlimae gen. nov. are easily distinguished by the comparative morphology of their haptoral armature. In Susanlimae gen. nov., the ventral and...

Ticks (Acari: Ixodidae) from yellow armadillo, Euphractus sexcinctus (Cingulata: Dasypodidae), in Brazil's Pantanal wetlands
Provedor de dados: 82
Autores: Medri,Ísis M; Martins,João R; Doyle,Rovaina L; Mourão,Guilherme; Marinho-Filho,Jader.
Tick species parasitizing yellow armadillo, Euphractus sexcinctus, were recorded from October 2006 to October 2007 in Pantanal. A total of 89 ticks were collected from 23 yellow armadillos. Most ticks (n = 50) were identified as Amblyomma cajennense (Fabricius) (32 males and 18 females). The only other species found was Amblyomma parvum (Aragão) (three females and two males). The remaining ticks were immatures of Amblyomma (29 nymphs and five larvae). The prevalence of A. cajennense was 55%, the mean intensity was 2.7 ± 0.5 (SE) (n = 17) and the mean abundance was 1.5 ± 0.4 (n = 31).
