Ticks (Ixodidae) on humans in South America
Twenty eight species of Ixodidae have been found on man in South America and ticks of the genus Ixodes do not appear to be major players in transmitting diseases to human.
Borrelia chilensis, a new member of the Borrelia burgdorferi sensu lato complex that extends the range of this genospecies in the Southern Hemisphere.
The presence of culturable spirochetes with flat-wave morphology and borrelial DNA in endemic Ixodes stilesi ticks collected in Chile from environmental vegetation and long-tailed rice rats is reported.
Marked phylogeographic structure of Gentoo penguin reveals an ongoing diversification process along the Southern Ocean.
Ticks (Acari: Ixodoidea: Argasidae, Ixodidae) of Chile
The Chilean Ixodes fauna is unique to the Neotropical Zoogeographic Region, and additional research is needed in order to understand the biological importance of these species.
Molecular methods routinely used to detect Coxiella burnetii in ticks cross-react with Coxiella-like bacteria
Background Q fever is a widespread zoonotic disease caused by Coxiella burnetii. Ticks may act as vectors, and many epidemiological studies aim to assess C. burnetii prevalence in ticks. Because
Detection of Evolutionarily Distinct Avian Influenza A Viruses in Antarctica
The H11N2 viruses sampled from Adélie penguins from two geographically different sites in Antarctica are characterized and it is shown that the segmented AIV genome diverged between 49 and 80 years ago from other AIVs, with several genes showing similarity and shared ancestry with H3N8 equine influenza viruses.
Genetic divergence of Chilean long‐tailed snake (Philodryas chamissonis) across latitudes: conservation threats for different lineages
This study aimed at elucidating the evolutionary history of P. chamissonis in Chile by analysis of mitochondrial DNA sequences.
Characterization and Comparison of Extended-Spectrum β-Lactamase (ESBL) Resistance Genotypes and Population Structure of Escherichia coli Isolated from Franklin's Gulls (Leucophaeus pipixcan) and
The general level of antibiotic resistance is investigated with further analysis of extended-spectrum beta-lactamase (ESBL) prevalence, as well as the population structure of E. coli in fecal flora of humans and Franklin’s gulls in central parts of Chile, to find a surprisingly high carriage rate of ESBL-producingE.
Genetic and Morphological Evidences for the Existence of a New Species of Contracaecum (Nematoda: Anisakidae) Parasite of Phalacrocorax brasilianus (Gmelin) From Chile and Its Genetic Relationships
The erection of a new taxon from fish-eating birds of the Austral region is given and its formal description is presented, and the finding of C. australe n.
Meta-transcriptomics reveals a diverse antibiotic resistance gene pool in avian microbiomes
These transcriptome data suggest that human waste, even if it undergoes treatment, might contribute to the spread of antibiotic resistance genes to the wild and show that meta-transcriptomics is a valuable tool to access functional resistance genes in whole microbial communities.
