Article Abstract
The aim is to describe the Typhus group (TG) infection in dogs and to identify factors associated with this infection. We collected blood samples and gathered exposure and clinical data of 142 dogs from a rural community of Yucatan. The group was determined by semi-nested PCR. Generalized linear models with binomial error distribution were used to model the associated factors from the dog sample for risk ratio (RR) estimation. Thirty-four dogs (23.9%) showed molecular evidence of TG DNA. The multivariate model showed that mixed-breed dogs (RR = 0.06) and dogs that had received antiparasitic treatment (RR = 0.049) had a lower risk of getting infected, taking as reference the purebred group and the non-treated dogs, respectively. Looking at variable interactions, adult dogs without outdoor activities had a lower infection risk than puppies (RR = 0.26). Among dogs with antiparasitic treatment, females had a higher infection risk than male dogs (RR = 26.2). The results showed enzootic TG circulation in dogs of a rural community. The factors outdoor activities, age and previous antiparasitic treatment, as well as the clinical variables signs of hemorrhages and epistaxis, were associated with a less chance of natural infection in the studied dogs. Prevention and control of the enzootic transmission risk of TG should help to reduce the potential zoonotic transmission of this pathogen.

This study aimed to histomorphometrically evaluate the effect of guided bone regeneration (GBR) and two implant surfaces on the thickness and height of newly formed bone in dehiscence defects around titanium implants. Three premolars and the first bilateral molar were extracted from ten adult mongrel dogs, and 40 buccal bone dehiscences measuring 5 mm in height and 4 mm in width were created using a University of North Carolina (UNC) periodontal probe to confirm the dimensions. Forty implants were randomly assigned to one of four groups: oxidized implant surfaces (OIS, n = 10), turned/machined implant surfaces (TIS, n = 10), OIS + GBR (n = 10), and TIS + GBR (n = 10).

Understanding dog behavior, especially in the context of the human social environment, is critical to maintaining positive human-dog interactions and relationships. Furthermore, behavior can be an important indicator of health and welfare in companion dogs. Behavioral change can signal transitions in life stages, alert caretakers to potential illnesses or injuries, and is an important factor in understanding and measuring stress.

Syringomyelia is a common and heritable disorder in Cavalier King Charles Spaniels (CKCS), characterised by fluid accumulation within the spinal cord that may result in pain and neurological dysfunction. The prevalence of syringomyelia in CKCS in Australia has not previously been reported. The goal of this study was to assess the prevalence and severity of syringomyelia in magnetic resonance imaging (MRI)-screened breeding CKCS in New South Wales, Australia, from 2008 to 2024, and to evaluate changes over time.

Objectives: A thorough understanding of common practice patterns in a particular specialty can help identify and design new interventions to improve care delivery and access to care. The goals of this study were to document current practice patterns among veterinary "neurologists" and small animal "surgeons" in the surgical management of acute canine thoracolumbar intervertebral disc extrusion, to compare approaches between these two groups and to discuss current results compared to those published in 2016.
Materials And Methods: A web-based survey was distributed in October 2024 to collect responses from board-certified and regionally recognised neurology and surgery specialists in North America and Europe.
Herbivore effects on plant quality and quantity in a shortgrass prairie.

The Earth's grasslands have experienced extensive alterations to their grazing regimes over the course of human history. We asked how native grassland herbivores (bison, prairie dogs, and grasshoppers) and a non-native herbivore that has become dominant (cattle) affect seasonal patterns of plant and soil elemental chemistry and aboveground plant biomass in a shortgrass prairie in the North American Northern Great Plains. To quantify herbivore effects, we sampled plants and soils across 4 months of the growing season in 15 grassland sites comprising five herbivore regimes with varying densities of bison, cattle, prairie dogs, and grasshoppers.
