Subject:
Aves polyomavirus 1; Beak and feather disease virus; beak; bird diseases; birds; feathers; genes; genetic variation; hosts; polymerase chain reaction; Chile
Abstract:
... Avian polyomavirus disease and psittacine beak and feather disease (PBFD) are both contagious viral diseases in psittacine birds with similar clinical manifestations and characterized by abnormal feathers. To determine the prevalence of Aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) in captive, exotic psittacine birds in Chile, feathers from 250 psittacine birds, representing ...

Infectious bronchitis virus; RNA; birds; flocks; genetic analysis; genetic variation; genome; monitoring; mutation; phylogeny; poultry industry; serotypes; vaccination; vaccines; viruses; Argentina; Brazil; Chile; Colombia; Peru; Uruguay
Abstract:
... Infectious bronchitis virus (IBV) is a persistent sanitary problem for the South American poultry industry despite extensive vaccination. The IBV single-stranded RNA genome has high rates of mutation and recombination that generate a notorious virus variability. Since most IBV vaccines are type-specific, there is a need for constant surveillance of the circulating lineages and knowledge about thei ...

3. Determining Intermediate Hosts for Opecoelidae and Microphallidae Species (Platyhelminthes: Trematoda) in the Southeastern Pacific Coast, Using Molecular Markers

Subject:
Decapoda; Labrisomus; Maritrema; Microphallus; Opecoelidae; adults; birds; coasts; fish; food webs; genes; genetic distance; genetic markers; genetic variation; intermediate hosts; littoral zone; metacercariae; ribosomal RNA; Chile
Abstract:
... Metacercarial stages of digeneans were collected from decapod crustaceans inhabiting intertidal rocky zones in central Chile. The digeneans were identified through a molecular analysis based on the V4 region of the 18S ribosomal RNA gene. We analyzed 356 crustaceans belonging to 10 species, 115 intertidal fish belonging to 6 species, and 4 specimens of 1 coastal bird species. In total, 74.1% of cr ...

4. Comparative phylogeography of co-distributed Phrygilus species (Aves, Thraupidae) from the Central Andes

Thraupidae; birds; climate change; demography; drying; ecoregions; genetic variation; mitochondria; natural selection; phenotype; phylogeny; phylogeography; population structure; sympatry; taxonomy; tropics; Andes region; Chile
Abstract:
... The Neotropical ecoregion has been an important place of avian diversification where dispersal and allopatric events coupled with periods of active orogeny and climate change (Late Pliocene–Pleistocene) have shaped the biogeography of the region. In the Neotropics, avian population structure has been sculpted not only by geographical barriers, but also by non-allopatric factors such as natural sel ...

5. Genetic differentiation of the Thorn-tailed Rayadito Aphrastura spinicauda (Furnariidae: Passeriformes) revealed by ISSR profiles suggests multiple palaeorefugia and high recurrent gene flow

Abstract:
... Nucleotide sequence data (cytochrome b) and ISSR genomic fingerprints were used to analyse the genetic variation and population differentiation in Thorn-tailed Rayadito, a widespread Patagonian forest bird. We included samples from eight populations of Thorn-tailed Rayadito covering most of the distribution range of the species: from fragmented patches of Olivillo forest in northern Chile to Isla ...
