Marsupials in the Age of Genomics

open access: yesAnnual Review of Genomics and Human Genetics, 2013
Marsupials are “alternative mammals” that differ from eutherians most spectacularly in their mode of reproduction and sexual differentiation. They represent a 160-million-year-old isolate from the more numerous eutherians, making them particularly valuable for comparative genome studies that enlarge and enhance our understanding of the function and ...

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

open access: yesJournal 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.

Exploring Trypanosoma cruzi transmission dynamics in an acute Chagas disease outbreak using next-generation sequencing

open access: yesParasites & Vectors
Background Chagas disease (CD), caused by Trypanosoma cruzi, poses a major global public health challenge. Although vector-borne transmission is the primary mode of infection, oral transmission is increasingly concerning. Methods This study utilized long-

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

open access: yesJournal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Layer‐by‐layer soft‐tissue effects on flexion–extension‐dominant passive ex vivo limb joint ROM in quadrupedal mammals: An anatomical contribution to a morphofunctional framework

open access: yesJournal of Anatomy, EarlyView.
Layer‐by‐layer passive ex vivo assessment of flexion–extension‐dominant limb joint ROM across rabbit, pudu deer, chilla fox and pig revealed joint‐, tissue‐ and taxon‐specific responses to progressive tissue removal. Proximal joints often showed increasing ROM, whereas distal joints often showed non‐monotonic responses.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

open access: yesMedical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

Immunogenetics of marsupial B-cells

open access: yes, 2020
Marsupials and eutherians are mammals that differ in their physiological traits, predominately their reproductive and developmental strategies; eutherians give birth to well-developed young, while marsupials are born highly altricial after a much shorter

Eco‐Epidemiological Study of Seropositivity Against Rickettsia and Leptospira Agents in Rural Areas of Urabá, Colombia

open access: yesTropical Medicine &International Health, EarlyView.
ABSTRACT Introduction Rickettsioses and leptospirosis are infectious diseases often underdiagnosed due to limited knowledge about their epidemiology, pathophysiology, and clinical aspects. Objectives To characterize the seroprevalence and seroincidence of Rickettsia and Leptospira agents and determine their associated factors in rural areas of Urabá ...

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

open access: yesZoonoses 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
