Abstract Introduction: From 2011 to 2016, 24 cases of Chagas disease were reported in Córdoba according to the national public health surveillance system (Sistema Nacional de Vigilancia en Salud Pública, Sivigila), but the information regarding Trypanosoma cruzi circulating strains and infection rates...

Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur locomotion. Using a comparative biomechanical approach, we found that cursorial birds h...

In order to determine the presence and genetic diversity of Chlamydia spp. in the north-eastern area of Buenos Aires province, Argentina, conjunctival, oropharyngeal, cloacal swab and tissues were collected from a total of 90 psittacine pet birds of different age and clinical manifestations. Through mole...
Abstract The aim of this study is to detect the presence of tick-borne agents of genera Rickettsia, Borrelia, Babesia, Ehrlichia and Anaplasma in ticks collected from native wild birds in the state of Rio de Janeiro. Birds were captured and observed carefully to find the ectoparasites. DNA detection of h...

Abstract Portugal has some rehabilitation centers for wild animals, which are responsible for the rehabilitation and reintroduction of birds, among other animals, into the wild. Coccidian parasites of these wild birds in rehabilitation centers are especially important because these centers can introduce ...

Published evidence reports the existence of two routes for the transformation of 7-dehydrocholecalciferol into previtamin D3: a photochemical route with the participation of UVB photons and another route that occurs
in the darkness. Several reports appears to support the presence of these two routes in s...
Abstract The avoidance of vertebrate herbivory is thought to be one of the possible drivers for the evolution of epiphytism. Scarce literature suggests that epiphyte herbivory is mainly related to insect attack on reproductive structures. In a pine-oak forest we observed almost all inflorescences of an ...
Abstract General changes in land use have established patterns of modification of native vegetation into agricultural and grazing land. These production systems, as well as social and economic influences, have created diverse landscapes - mosaics composed of varied elements of vegetation cover (forests, ...
The present study investigated the circulation of avian metapneumovirus (aMPV) in wild birds in Brazil. To do so, 131 samples from 366 oropharyngeal or cloacal swabs collected from 18 species of birds were tested individually or in pools by RT-PCR. Samples detected by RT-PCR were selected for DNA sequenc...
En Paraguay, no se han registrado casos autóctonos de malaria desde el 2011. Se realizó un estudio descriptivo observacional transversal en 6 monos y 23 aves que vivían en una región históricamente endémica de Paraguay para buscar presencia de reservorios silvestres de parásitos plasmodios causant...
