Prevalence and mechanisms of fluoroquinolone-resistant among sheltered companion animals.

To better understand the prevalence of fluoroquinolone-resistant among sheltered companion animals, we conducted a screening study of 38 dogs and 78 cats and investigated the resistance mechanisms and characteristics of the isolates. Fluoroquinolone-resistant was detected in 18 dogs (47.4 %) and 14 cats (17.

Prevalence and genetic characterization of cephalosporin-resistant Enterobacteriaceae among dogs and cats in an animal shelter.

Purpose: The prevalence of antimicrobial-resistant bacteria, especially cephalosporin-resistant Enterobacteriaceae, is a major concern for human and animal health. We investigated the prevalence of cephalosporin-resistant Enterobacteriaceae among sheltered dogs and cats with various backgrounds.

Method: Faecal samples or rectal swabs were collected from 151 dogs and 182 cats, and screened for the presence of antimicrobial-resistant bacteria.

Luminescence and Valence of Tb Ions in Alkaline Earth Stannates and Zirconates Examined by X-ray Absorption Fine Structures.

The difference in Tb green luminescence intensities in doped perovskite(ABO)-type alkaline earth stannates, AeSnO (Ae = Ca, Sr, Ba), and the Mg codoping effect on the luminescence intensities in doped CaMO (M = Sn, Zr) were investigated utilizing the X-ray absorption fine structures (XAFS) of the Tb L absorption edge. It is considered that the local symmetry at A sites is responsible for the different Tb luminescence intensities in AeSnO (Ae = Ca, Sr, Ba) doped with Tb ions at A sites. However, it was found from the XAFS spectra that some Tb ions are unintentionally stabilized at B sites as Tb, especially in BaSnO.
