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

Acta Zoologica, EarlyView.
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.

Dark diversity of flea (Siphonaptera) assemblages in South American rodents: Latitudinal and altitudinal gradients

Ecological Entomology, EarlyView.
The dark diversity of compound flea communities increased from north to south. The dark diversity of compound flea communities increased from lower to higher altitudes. The dark diversity of component flea communities also increased from north to south but did not vary with altitude.

Comparison of coproparasitological diagnoses in cats: evaluation of techniques and their combinations

Journal of Small Animal Practice, EarlyView.
Objectives To compare the Willis, Sheather, Faust, Ritchie and spontaneous sedimentation techniques, as well as their combinations, for the diagnosis of gastrointestinal parasites in domestic and semi‐domesticated felines. Materials and Methods Coproparasitological analyses were conducted on domestic cats of both sexes and all age groups, including ...

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 ...

Parasite–Host Associations in Pinworms (Trypanoxyuris spp.) From Spider Monkeys (Ateles spp.)

American Journal of Primatology, Volume 88, Issue 8, August 2026.
Lineages in pinworms from Ateles monkeys are highly host‐specific and their diversification patterns reflect host biogeographic and evolutionary histories. ABSTRACT Pinworms of primates are highly host‐specific parasites that, in several lineages, are known to share their evolutionary history with that of their hosts.

Murine T Cell‐Dependent Response Affects Leishmania amazonensis Amastigote Survival and Virulence

Cell Biology International, Volume 50, Issue 8, August 2026.
ABSTRACT Our group has previously described the infection course of Leishmania amazonensis in BALB/c and BALB/cnu/nu mice, which have distinct T‐cell dependent responses. In this study, lesion‐derived amastigotes exhibited differential protein expression in a host‐dependent manner.

Rituximab Binding Endows CD20+ Extracellular Vesicles With NK Cell‐Activating Properties in B Cell Lymphoma

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
B cell lymphoma‐derived EVs are intrinsically neutral or suppressive with respect to NK cell activity (panel 1). In the context of rituximab treatment, NK cytotoxicity is enhanced by antibody‐dependent cell‐mediated cytotoxicity (panel 2). Herein we show that, in addition, rituximab recognition of EV‐associated CD20 generates immune complexes that ...

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, Volume 82, Issue 8, Page 7794-7808, August 2026.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...
