Companion animals as sources of hazardous critically important antimicrobial-resistant Escherichia coli: Genomic surveillance in Shanghai.

This study provides the first comprehensive genomic surveillance of critically important antimicrobial (CIA)-resistant Escherichia coli in companion animals, addressing gaps in the understanding of antimicrobial resistance (AMR) transmission dynamics and the environmental dissemination of hazardous resistance genes within urban ecosystems. A total of 244 CIA-resistant Escherichia coli (CIA-EC) isolates were obtained from 730 anal swabs collected across 11 pet hospitals in Shanghai. High-risk zoonotic clones, such as ST410 and ST405, were identified across multiple districts, with bla-positive IncX3 plasmids demonstrating exceptional stability, efficient conjugation, and broad host adaptability.

Genetic Characterization and Zoonotic Analyses of from Cats and Dogs in Shanghai in China.

is reported to be a common microsporidian of humans and animals in various countries. However, limited information on has been recorded in cats () and dogs () in China. Here, we undertook molecular epidemiological investigation of in cats and dogs in Shanghai, China.

Metagenomic insights into the resistome, mobilome, and virulome of dogs with diverse lifestyles.

Background: Dogs-whether pets, rural, or stray-exhibit distinct living styles that influence their fecal microbiota and resistomes, yet these dynamics remain underexplored. This study aimed to analyze and compare the fecal microbiota and resistomes of three groups of dogs (37 pets, 20 rural, and 25 stray dogs) in Shanghai, China.

Results: Metagenomic analysis revealed substantial differences in fecal microbial composition and metabolic activities among the dog groups.

A Novel Immunochromatographic Test Strip Using Lanthanide-Labeled Fluorescent Nanoparticles for the Serological Detection of in Dogs and Cats.

() is an important zoonotic pathogen which induces both acute and chronic toxoplasmosis. Timely diagnosis of is crucial for effective disease management. Here, we present a pioneering approach using europium (III)-chelated nanoparticles (EuNPs) in a rapid lateral flow immunochromatographic test strip (ICTS) for detecting antibodies in serum samples.

Influence of maternal body mass index on pregnancy complications and outcomes: a systematic review and meta-analysis.

Background: The prevalence of obesity among women of reproductive age is increasing worldwide, with implications for serious pregnancy complications.

Methods: Following PRISMA guidelines, a systematic search was conducted in both Chinese and English databases up to December 30, 2020. Pregnancy complications and outcomes including gestational diabetes mellitus (GDM), gestational hypertension (GHTN), pre-eclampsia, cesarean section (CS), induction of labor (IOL), and postpartum hemorrhage (PPH) were analyzed.

Comparison of dye-based and probe-based RT-LAMP in detection of canine astrovirus.

A rapid and sensitive assay is essential for reliable surveillance and diagnosis of canine astrovirus (CaAstV). In this study, two real-time reverse transcription loop-mediated isothermal amplification (RT-LAMP) assays with high sensitivity, rapidity, and reliability were developed using fluorescence dye and FRET-based assimilating probes for real-time detection of CaAstV. These assays specifically amplified the ORF2 gene of CaAstV and did not amplify any sequences from canine enterovirus.

A Recombinase-Aided Amplification Assay for the Detection of .

is an important zoonotic agent for humans and various animals. A recombinase-aided amplification (RAA) assay was developed for detecting . RAA can be performed in a closed tube at 39°C within 30 min.

DON entry into the nucleus induces DNA damage, apoptosis and cycle arrest in GES-1 cells.

Deoxynivalenol (DON) is a mycotoxin produced by the genus Fusarium and belongs to the trichothecenes group B compound. At present, the mechanism of DON toxicity to mammalian cells is not fully understood. Since the stomach is the first physiological barrier against food contaminants, it is also the first target of exposure to toxins.

Estimation of the Rural Dog Population Within a Mega-City: An Example in Jiading District, Shanghai.

Rural dog populations have long been recognized to be inadequately managed in terms of disease control and prevention. In this study we consider dog management in rural Shanghai and its implications for rabies control in the entire metropolitan area of Shanghai. The prerequisite to improve rabies vaccination coverage in rural Shanghai depends on a proper enumeration of the total rural dog population.

Epidemiology of pseudorabies in intensive pig farms in Shanghai, China: Herd-level prevalence and risk factors.

Pseudorabies (PR), also known as Aujeszky's disease, is a highly contagious disease affecting pigs and a wide range of animals. Pseudorabies is enzootic in many countries. In China, it is a priority animal disease for control and eradication, however the data on disease frequency in intensive pig farms and the information on associated risk factors is inadequate.

Prevalence of Stx phages in environments of a pig farm and lysogenic infection of the field E. coli O157 isolates with a recombinant converting Phage.

The prevalence and nature of Shiga toxin (Stx)-producing Escherichia coli (STEC) and Stx phage were investigated in 720 swine fecal samples randomly collected from a commercial breeding pig farm in China over a 1-year surveillance period. Eight STEC O157 (1.1%), 33 STEC non-O157 (4.

[Biologic characteristics of eight Podoviridae Stx2-converting phage].

Objective: We studied biologic characteristics of Stx2-converting phage induced from Escherichia coli O157 by mitomycin C.

Methods: Eight Stx2-converting phages were isolated from E. coli O157 and identified by PCR.
