Anatomical description of the jaw muscles and theoretical bite force assessment in South American opossums using manual and digital dissection methods

Journal of Anatomy, EarlyView.
Manual and virtual dissections were employed to examine the masticatory muscle architecture and bite force of three South American marsupials. The organisation of the muscles differed between species, with predicted bite forces exceeding previous estimates.

Short Report: First Outbreak of Atlantic Rainforest Spotted Fever in North‐Eastern of Brazil—Clinical Features and Eco‐Epidemiological Investigation

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Since 2010, six cases of Atlantic rainforest spotted fever (ARSF) have been confirmed and reported in Brazil, a tick‐borne disease caused by Rickettsia parkeri strain Atlantic rainforest and associated with the tick Amblyomma ovale. So far, none of the cases have been associated with death. One of the cases occurred in 2018 in the

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

Acta Zoologica, Volume 107, Issue 4, Page 460-469, October 2026.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Avian influenza overview June–August 2026

EFSA Journal, Volume 24, Issue 9, September 2026.
Abstract Between 5 June and 28 August 2026, 110 highly pathogenic avian influenza (HPAI) A(H5N1) virus detections were reported in domestic (7) and wild (103) birds in 12 countries in Europe. The number of detections remained at a seasonal low throughout the summer, continuing the decline observed since spring.
