| genotyping of cryptosporidium spp. from free-living wild birds from brazil. | in wild and domestic birds, cryptosporidiosis is often associated with infections by cryptosporidium galli, cryptosporidium baileyi and cryptosporidium meleagridis. in addition to these species, a number of avian cryptosporidium species yet to be fully characterized are commonly found among exotic and wild avian isolates. the present study aimed to detect and identify samples of cryptosporidium spp. from free-living wild birds, in order to contribute to the knowledge of the variability of this p ... | 2010 | 21035268 |
| effects of tramadol on the minimum anesthetic concentration of isoflurane in white-eyed parakeets (psittacara leucophthalmus). | the aim of this study was to determine the minimum anesthetic concentration (mac) of isoflurane, and to investigate if tramadol changes the isoflurane mac in white-eyed parakeets (psittacara leucophthalmus). ten adult birds weighing 157 ± 9 g were anesthetized with isoflurane in oxygen under mechanical ventilation. isoflurane concentration for the first bird was adjusted to 2.2%, and after 15 min an electrical stimulus was applied in the thigh area to observe the response (movement or nonmovemen ... | 2017 | 28749279 |
| morphofunctional evaluation of the testicle and the spermatogenic process of adult white-eyed parakeets (aratinga leucophthalma muller, 1776) during the different seasons of the year. | in this experiment, testicle fragments of 14 adult white-eyed parakeets (aratinga leucophthalma) were evaluated as for their seasonal reproductive activities using the following quantitative parameters: average thickness of the testicular tunica albuginea, volumetric proportion of tubular and extratubular compartments, average diameter of the seminiferous tubules and corporal weight. parameters were created for qualitative evaluations of the degree of spermatogenic development. in this experimen ... | 2012 | 22211874 |
| faecal virome analysis of wild animals from brazil. | the brazilian cerrado fauna shows very wide diversity and can be a potential viral reservoir. therefore, the animal's susceptibility to some virus can serve as early warning signs of potential human virus diseases. moreover, the wild animal virome of this biome is unknown. based on this scenario, high-throughput sequencing contributes a robust tool for the identification of known and unknown virus species in this environment. in the present study, faeces samples from cerrado birds (psittacara le ... | 2019 | 31480274 |
| eimeria psittacarae n. sp. (apicomplexa: eimeiriidae) from white-eyed parakeets psittacara leucophthalmus (müller, 1776) (psittaciformes: psittacidae) kept for rehabilitation and reintroduction in the parque nacional da serra dos órgãos, southeastern brazil. | a new species of coccidia (protozoa: apicomplexa: eimeriidae) found parasitizing the white-eyed parakeet psittacara leucophthalmus (müller, 1776) in brazil is described. eimeria psittacarae n. sp. has oocysts that are ellipsoidal, 34.8 × 24.3 μm, with smooth, bilayered wall, ~1.7 μm thick. micropyle present. oocyst residuum absent, but one or two polar granules are present. sporocysts are elongate ellipsoidal, 19.2 × 9.7 μm. stieda body knob-like and sub-stieda body rounded. sporocyst residuum i ... | 2018 | 30314136 |
