Potential for conflict between urban coyotes and people experiencing unsheltered homelessness

Frontiers in Ecology and the Environment, EarlyView.
Across North America, both unsheltered homelessness and human–coyote (Canis latrans) conflict are increasing, but the relationship between these phenomena has not been thoroughly explored. We synthesize literature‐based evidence with anecdotal observations that occurred during a 15‐year study of coyotes in Edmonton, Canada, to describe three likely ...

Pathogenicity and Transmissibility of North American H7 Low Pathogenic Avian Influenza Viruses in Chickens and Turkeys

Viruses, 2019
Low pathogenic avian influenza (LPAI) viruses can silently circulate in poultry and wild aquatic birds and potentially mutate into highly pathogenic avian influenza (HPAI) viruses.

HIV Transmission [PDF]

Cold Spring Harbor Perspectives in Medicine, 2012
HIV-1 is transmitted by sexual contact across mucosal surfaces, by maternal-infant exposure, and by percutaneous inoculation. For reasons that are still incompletely understood, CCR5-tropic viruses (R5 viruses) are preferentially transmitted by all routes.

Networks of Indirect Contact Promote Spread of an Environmentally Transmitted Pathogen in a Highly Social Species. [PDF]

Ecol Evol
Using behavioral observations and network simulations, we evaluate direct and indirect transmission of the MTBC pathogen M. mungi in banded mongooses. Incorporating intergroup scent marking reveals that environmentally mediated, socially directed pathways can promote spread at low transmissibility, elevating population prevalence even when direct ...

Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

iMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

BacSafe: A Comprehensive Database for Integrated Assessment of Bacterial Biosafety

iMetaMed, EarlyView.
The substantial threats that bacterial contamination poses to healthcare and industrial production requires a comprehensive assessment of biosafety risks for each bacterial species. Here, we introduce BacSafe, a novel database that integrates diverse domains of biosafety knowledge and evaluates bacterial risk across both clinical and environmental ...

The Spectrum of Abnormal Tongue Movements: Review of Phenomenology, Etiology, and Differential Diagnosis

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Classifying abnormal tongue movements is challenging due to their varied presentations and limited visibility compared to other body parts. Accurate identification of the phenomenology guides physical examination and can point to specific diagnoses.
