Characterization of the Middle Ear Microbiome in Meniere's Disease by 16S rRNA Gene Sequencing Compared to Chronic Suppurative Otitis Media

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To investigate the middle ear microbiome in Meniere's disease (MD) patients. Methods Middle ear smears from 10 MD patients (ME group) and 10 chronic suppurative otitis patients (OE group) were collected during surgery and processed via 16S rRNA gene sequencing.

Polymorphisms for Defence and Virulence in the Arabidopsis thaliana–Cucumber mosaic virus Interaction Are Expressed in the Host’s Native Habitat

Viruses
Plant defences are assumed to evolve in response to the negative effects of virus infection on plant fitness (virulence), and to drive plant–virus coevolution.

Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

Wildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.

From landscapes to lesions: Pathology's role in wildlife mortality investigations and conservation health

Wildlife Society Bulletin, EarlyView.
Wildlife mortality investigations are important toward understanding health threats to wildlife and management considerations. The who, what, why and how are critical pieces of these investigations. Wildlife pathologists play a central role in this process in elucidating causes and contributors to mortality. Abstract To effectively recognize and manage

Hotter, faster, sicker? Warming shifts the cost of infection from individuals to populations

Journal of Animal Ecology, EarlyView.
This study examines how temperature alters disease impacts across biological scales in a host–pathogen system. We found infected hosts appear healthiest at warm temperatures, yet populations suffer most. This suggests climate warming may intensify disease impacts for populations in ways traditional individual‐level virulence metrics fail to predict ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.
