Article Synopsis
- - The introduction of the non-native winter crane fly, Trichocera maculipennis, in maritime Antarctica may threaten the unique local ecosystem, which is vulnerable to foreign species.
- - Researchers conducted tests using advanced methods to determine if T. maculipennis could mechanically transmit various viruses, and identified several human and plant virus genomic fragments in samples collected from the fly.
- - Although the study found low amounts of human adenovirus and retrovirus in the fly samples, which were non-viable, it highlights the need for ongoing research into the impacts of non-native species on Antarctic ecosystems.
Article Synopsis
- * In a trial, 74 heifers were vaccinated with different strains and then exposed to naturally infected animals, but the initial vaccination did not produce an adequate immune response, and re-vaccination did not show significant protection against the disease.
- * The study found a 23% transmission of wild-style strains in non-vaccinated animals, and while some vaccine candidates showed promise in reducing lesions, overall results indicated that further evaluation is needed, as current vaccines did not ensure improved outcomes.
Unexpected Delayed Incursion of Highly Pathogenic Avian Influenza H5N1 (Clade 2.3.4.4b) Into the Antarctic Region.
Influenza Other Respir Viruses
October 2024
The current highly pathogenic avian influenza H5N1 panzootic is having substantial impacts on wild birds and marine mammals. Following major and widespread outbreaks in South America, an incursion to Antarctica occurred late in the austral summer of 2023/2024 and was confined to the region of the Antarctic Peninsula. To infer potential underlying processes, we compiled H5N1 surveillance data from Antarctica and sub-Antarctic Islands prior to the first confirmed cases.

However, Bd studies on Neotropical amphibians from temperate areas are scarce. We present a comprehensive survey of Bd in Uruguay, in temperate central eastern South America, carried out between 2006 and 2014.

In contrast to the Arctic Ocean, studies documenting Hg contamination in the Southern Ocean are spatially restricted and large-scale monitoring is needed. Here, we present the first circumpolar assessment of Hg contamination in Antarctic marine ecosystems.
