Combination of in silico and molecular techniques for discrimination and virulence characterization of marine Brucella c...

Published in Frontiers in Microbiology

Introduction Mammals are the main hosts for Brucella sp., agents of worldwide zoonosis. Marine cetaceans and pinnipeds can be infected by Brucella ceti and B. pinnipedialis, respectively. Besides classical bacteriological typing, molecular approaches such as MLVA, MLSA, and whole-genome sequencing (WGS) can differentiate these species but are cumbe...

Viral metagenomic survey of Caspian seals

Published in Frontiers in Veterinary Science

Introduction Viral diseases of pinnipeds cause substantial mortality and morbidity and can influence population demography. Viral metagenomic studies can therefore play an important role in pinniped health assessments and disease surveillance relevant to both individual species and in a “One Health” context. Methods This study used a metagenomic ap...

Pinnipeds and avian influenza: a global timeline and review of research on the impact of highly pathogenic avian influen...

Published in Frontiers in Cellular and Infection Microbiology

This study reviews chronologically the international scientific and health management literature and resources relating to impacts of highly pathogenic avian influenza (HPAI) viruses on pinnipeds in order to reinforce strategies for the conservation of the endangered Caspian seal (Pusa caspica), currently under threat from the HPAI H5N1 subtype tra...

Trace element concentrations in common dolphins (Delphinus delphis) in the Celtic Seas ecoregion: Interelement relations...

peer reviewed / Given the increased extraction of trace elements for use by new and emerging technologies, monitoring the environmental fate and potential effects of these compounds within the aquatic environment has never been more critical. Here, hepatic trace element concentrations were assessed in a key sentinel predator, the common dolphin (De...

Unraveling the gut microbiota of Mexican pinnipeds: the dominance of life histories over phylogeny

Published in Applied and Environmental Microbiology

Pinnipeds in Mexico host microbial communities that remain understudied. While several factors can influence microbiota composition, the role of phylogenetic relationships among these pinnipeds remains unclear due to limited knowledge of the microbiota in certain species. This study aimed to fill this gap by characterizing the composition and funct...

Isotopic niches reveal the trophic structure of the cetacean community in the oceanic waters around the Azores

Published in Frontiers in Marine Science

Introduction The oceanic waters around the Azores host a high diversity of cetaceans, with 28 species of toothed and baleen whales present year-round or seasonally. This high cetacean biodiversity likely plays an important role in the structure, functioning and productivity of the ecosystem, and may increase trophic redundancy, thus contributing to...

Physiological values of phagocytic capacity in marine mammals and alterations during pathological situations

Published in Frontiers in Veterinary Science

The study of the immune function in marine mammals is essential to understand their physiology and can help to improve their welfare in the aquariums. Dedicating efforts to studying marine mammal physiology, pathophysiology, and implementing new diagnostic and therapeutic tools promote progress towards preventive medicine in aquariums by facilitati...
