Comparison of three different self-expanding metal stents using rabbit models for the treatment of tracheal collapse.

Purpose: To identify an optimal self-expandable metallic stent (SEMS) and verify whether a mechanically superior SEMS would result in better clinical outcomes in the treatment of tracheal collapse.

Methods: We selected three SEMS (n = 8 each), including an S-type stent with a wire diameter of 0.006 inches (S6) and two D-type stents with wire diameters of 0.

Distribution and epidemiological relatedness of methicillin-resistant Staphylococcus aureus isolated from companion dogs, owners, and environments.

This study aimed to investigate the distribution and epidemiological relatedness of methicillin-resistant Staphylococcus aureus (MRSA) isolates from companion dogs, owners, and residential environments of 72 households. Sampling was performed twice from January to June 2018 and a total of 2,592 specimens were collected. The specimens collected from each household were streaked on CHROM agar S.

High-level mupirocin resistance in Gram-positive bacteria isolated from diseased companion animals.

The purpose of this study was to investigate the high-level mupirocin resistance (HLMR) in Gram-positive bacteria isolated from companion animals. A total of 931 clinical specimens were collected from diseased pets. The detection of mupirocin-resistant bacteria and plasmid-mediated mupirocin resistance genes were evaluated by antimicrobial susceptibility tests, polymerase chain reactions, and sequencing analysis.

Antimicrobial resistance and novel mutations detected in the gyrA and parC genes of Pseudomonas aeruginosa strains isolated from companion dogs.

Background: Fluoroquinolone agents, such as enrofloxacin and marbofloxacin, are commonly used for pseudomonal infection in veterinary medicine. However, the rate of resistance to fluoroquinolones is rapidly increasing, according to multiple studies in various countries. Point mutations in the quinolone resistance-determining region (QRDR) are closely related to the increased fluoroquinolone resistance of Pseudomonas aeruginosa.

Clonal Spread of Extended-Spectrum Cephalosporin-Resistant Between Companion Animals and Humans in South Korea.

Extended-spectrum cephalosporin (ESC)-resistant is an increasingly important problem in both human and veterinary medicine. The aims of this study were to describe a comparative molecular characterization of carrying ESC resistance genes, encoding extended-spectrum β-lactamase (ESBL) and AmpC, isolated from human stool samples, rectal swabs from companion animals, and swabs from the environment of veterinarian hospitals in South Korea, and to examine their possible dissemination and transmission. The ESC resistance genes were identified by PCR and sequencing.

First Detection of New Delhi Metallo-β-Lactamase-5-Producing Escherichia coli from Companion Animals in Korea.

The gene for New Delhi metallo-β-lactamase-5 (NDM-5) in Escherichia coli has been identified in many countries mainly from human clinical specimens. The isolates carrying this gene are even more rarely isolated from companion animals. In this study, four carbapenem-resistant isolates were recovered from four dogs in Korea.

Additive Effects of Rebamipide Plus Proton Pump Inhibitors on the Expression of Tight Junction Proteins in a Rat Model of Gastro-Esophageal Reflux Disease.

Background/aims: The aim of this study was to investigate the effects of rebamipide on tight junction proteins in the esophageal mucosa in a rat model of gastroesophageal reflux disease (GERD).

Methods: GERD was created in rats by tying the proximal stomach. The rats were divided into a control group, a proton pump inhibitor (PPI) group, and a PPI plus rebamipide (PPI+R) group.

Anterior cruciate ligament reconstruction in a rabbit model using canine small intestinal submucosa and autologous platelet-rich plasma.

Background: The bone-ligament interface is the main point of failure after anterior cruciate ligament reconstruction. Synthetic ligament materials have problems such as a greater failure rate of the bone-ligament insertion than autografts. Small intestinal submucosa (SIS) is a biologic scaffold that has been used to repair musculoskeletal tissue and has been shown to promote cell migration and enhance collagen fiber regeneration.
