Beyond Borders: Investigating the Mysteries of Cacipacoré, a Lesser-Studied Arbovirus in Brazil.

Cacipacoré virus (CPCV) was discovered in 1977 deep in the Amazon rainforest from the blood of a black-faced ant thrush (). As a member of the family Flaviviridae and genus orthoflavivirus, CPCV's intricate ecological association with vectors and hosts raises profound questions. CPCV's transmission cycle may involve birds, rodents, equids, bovines, marsupials, non-human primates, and bats as potential vertebrate hosts, whereas and spp.

The Complete Genome Sequences of 94 Species of Parrots (Psittaciformes, Aves).

We present the complete genome sequences of 94 species of parrots from 40 genera. Illumina sequencing was performed on genetic material from single individuals. The reads were assembled using a de novo method followed by a finishing step.

Tick infestation on caimans: a casual tick-host association in the Atlantic rainforest biome?

Ticks are parasites of birds, mammals, amphibians, and reptiles, but information about tick communities that parasitize reptiles in the Neotropical region is still fragmentary. In the present study, we assessed the presence of ticks on broad-snouted caimans (Caiman latirostris) and Cuvier's dwarf caimans (Paleosuchus palpebrosus) trapped in the Atlantic rainforest biome in Pernambuco state, north-eastern Brazil, to determine which tick species feed on these animals and how frequent or rare this parasite-wildlife association is. We also report an occasional finding of Amblyomma rotundatum on a smooth-fronted caiman (Paleosuchus trigonatus) in the Amazon biome in Pará state, northern Brazil.

Genome Sequence of a Divergent Avian Metapneumovirus from a Monk Parakeet ().

Here, we report the coding-complete genome sequence of an avian metapneumovirus from a monk parakeet (), identified by metagenomic next-generation sequencing during an investigation into a disease outbreak in a captive parrot breeding facility. Based on divergence from known strains, this sequence represents a new subgroup of avian metapneumovirus.

Does haemosporidian infection affect hematological and biochemical profiles of the endangered Black-fronted piping-guan (Aburria jacutinga)?

Infectious diseases can cause deleterious effects on bird species, leading to population decline and extinction. Haemosporidia can be recognized by their negative effects on host fitness, including reproductive success and immune responses. In captivity, outbreaks of haemosporidian infection have been observed in birds in zoos and aviaries.

Use of medetomidine for capture and restraint of cassowaries (Casuarius casuaris).

Objective: To examine the use of medetomidine for the sedation of captive and wild cassowaries (Casuarius casuarius).

Design: Clinical evaluation after administration of medetomidine by IM injection.

Procedure: Nine captive and two wild birds were chemically restrained, with the drug being administered by dart to 10 birds and hand injected to one.
