| an outbreak of chlamydiosis in captive blue-fronted amazon parrots (amazona aestiva) in brazil. | fifty-eight blue-fronted amazon parrot (amazona aestiva) nestlings, recovered from the illegal trade, became ill at a wildlife rehabilitation center in são paulo state, brazil. clinical signs observed were nonspecific, and the mortality rate was 96.5% despite initial treatment with norfloxacin. postmortem examinations were performed on 10 birds. liver and spleen smears showed structures suggestive of chlamydophila psittaci in four cases. diagnosis was confirmed by seminested polymerase chain rea ... | 2004 | 15193081 |
| isolation and molecular identification of lactic acid bacteria and bifidobacterium spp. from faeces of the blue-fronted amazon parrot in brazil. | in brazil, the blue-fronted amazon parrot (amazona aestiva) is a common pet. the faecal microbiota of these birds include a wide variety of bacterial species, the majority of which belong to the gram-positive lactic acid bacteria (lab) clade. the aim of this study was to investigate differences in the diversity and abundance of lab and bifidobacterium spp. in the cloacae between wild and captive birds and to select, identify and characterise lab for consideration as a parrot probiotic. cloacal s ... | 2014 | 25062609 |
| a new eimerian species (apicomplexa: eimeriidae) from the blue-fronted amazon parrot amazona aestiva l. (aves: psittacidae) in brazil. | the neotropical psittacine species amazona aestiva, commonly known as the blue-fronted amazon, is one of the most common and best-known psittacine birds kept as a pet worldwide. however, very little is known about the diseases or parasites of these birds. in this study, we describe a new species, eimeria aestivae, associated with these parrots. the new species is characterized by: ovoid smooth oocysts (n = 60), 36.8 (33.2-41.5) × 23.7 (21.7-25.7) µm, length/width ratio = 1.55; polar granule ... | 2011 | 21612420 |
| impacts of animal traffic on the brazilian amazon parrots (amazona species) collection of the quinzinho de barros municipal zoological park, brazil, 1986-2007. | eleven species of amazon parrots (genus amazona) are known to occur in brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. when the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. a retrospective survey of animal and necropsy records from 1986 to 2007 w ... | 2011 | 20069544 |
| crop damage of eriotheca gracilipes (bombacaceae) by the blue-fronted amazon (amazona aestiva, psittacidae), in the brazilian cerrado. | seed predation has major effects on the reproductive success of individuals, spatial patterns of populations, genetic variability, interspecific interactions and ultimately in the diversity of tree communities. at a brazilian savanna, i evaluated the proportional crop loss of eriotheca gracilipes due the blue-fronted amazon (amazona aestiva) during a fruiting period. also, i analyzed the relationship between proportional crop loss to amazons and both fruit crop size and the distance from the nea ... | 2014 | 25627593 |
| genetic variability in three amazon parrot species. | parrots of the genus amazona are among the most threatened species of the order pscittaciformes. this work describes allozyme polymorphisms in three amazon parrot species--the blue-fronted amazon (amazona aestiva), the orange-winged amazon (amazona amazonica), and the festive amazon (amazona festiva) -, and provides useful data for the evaluation of their genetic variability. we electrophoretically analyzed blood samples from 68 wild-caught individuals, maintained in captivity in three brazilian ... | 2007 | 18278355 |
