Universidad Nacional de Córdoba. Facultad de Ciencias Médicas. Instituto de Virología "Dr. J. M. Vanella"; Argentina.Borrelia burgdorferi sensu lato (s. l.) spirochetes are associated with a wide range of vectors and hosts. Birds are important hosts in the ecology of some hard ticks (Ixodidae) in northwestern Argentina, where B. burgdorferi s.l. have been detected in Ixodes pararicinus. We evaluated Borrelia infection in ticks collected from wild birds by molecular analysis through the presence of Borrelia DNA (by nested-PCR targeting the fla gene). A total of 381 ticks (357 larvae and 24 nymphs) belonging to four species (I. pararicinus, Haemaphysalis juxtakochi, Haemaphysalis leporispalustris and Amblyomma sp.) were collected. Partial sequences of the fla gene of Borrelia (100% identical to Borrelia sp. haplotype I from Argentina) were detected in 9 of 70 tick pools (6 pools of larvae and 1 pool of nymphs of I. pararicinus, and in 2 pools of H. juxtakochi larvae) collected on Turdus rufiventris, Syndactila rufosuperciliata and Troglodytes aedon. The results of this study suggest that resident birds have reservoir capacity for Borrelia sp. haplotype I.info:eu-repo/semantics/publishedVersionFil: Muñoz-Leal, Sebastián.

Description of a New Argasid Tick (Acari: Ixodida) from Bat Caves in Brazilian Amazon
Get PDFNothoaspis amazoniensis n. sp. (Acari: Ixodida: Argasidae) is described from adult and immature ticks (nymph II, nymphI, larva) collected from bat caves in the Brazilian Amazon. Also, 16S rDNA sequences are provided. The diagnostic characters foradults are the presence of false shield or nothoaspis, an anteriorly projecting hood covering the capitulum, a medial extension of palpalarticle I (flaps), genital plate extending from coxa I to IV, absence of 2 setae on the internal margin of the flaps, a minute hypostomewithout denticles, presence of a central pore in the base of hypostome, and a reticulate surface pattern on the posterior half of thenothoaspis in males. The nymph II stage is characterized by a hood that is small in relation to the capitulum, short coxal setae, palpalflaps lacking setae on the internal margin, long hypostome, pointed with dentition 4/4 apically, and the anterior half of the body iscovered by a cell-like configuration. Nymph I stage is characterized by a hood, small in relation to the capitulum, dorsum of the bodycovered by a cell-like configuration, venter integument covered by a cell-like configuration, and hypostome dentition 4/4 with apicesthat are ‘‘V’’-shaped. Diagnostic characters of the larvae are the number and size of dorsal setae, and the shape of scutum andhypostome. The new species appears to have a life cycle with a larva that feeds on bats, a non-feeding nymphal stage (nymph I), afeeding nymphal stage (nymph II), and adults that probably represent non-feeding stages.Fil: Nava, Santiago.

Marcelo dascal and the literal meaning debates
Get PDFWhat role does literal meaning play in people’s understanding of indirect and figurative language? Scholars from many disciplines have debated this issue forseveral decades. This chapter describes these debates, especially focusing on the arguments between the author and Marcelo Dascal. I suggest that Dascal’s defense of “moderate literalism” may have some validity, contrary to some of my earlier arguments against this point of view. The chapter acknowledges the strong contribution that Marcelo Dascal has made to interdisciplinary discussions on language and thought
