The impact of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae of food animal origins on human health has caught considerable attention worldwide. Intestinal Escherichia coli obtained from healthy food animals (pigs, cattle and poultry) in China were tested for the presence of ESBL genes. CTX-M-producing isolates were further characterised(More)
OBJECTIVE To determine pharmacokinetics and bioavailability of cefquinome administered IV, IM, or PO to healthy ducks. ANIMALS Thirty-six 2-month-old Muscovy ducks. PROCEDURES Ducks were randomly assigned to 3 groups of 12 birds each for a single IV, IM, or PO administration at a dose of 5 mg/kg. Blood samples were collected before and at various(More)
Streptococcus suis isolates from diseased pigs were examined for susceptibility to nine antimicrobials, possession of virulence-associated factors (VFs), and distribution of serotypes. The association between antimicrobial resistance (AMR) and serotypes as well as VFs was subsequently assessed. Among the isolates investigated, serotype 2 (66.04%) was mostly(More)
The aim of this study was to investigate the trends and the diversity of CTX-M types of extended-spectrum β-lactamase (ESBL) in Escherichia coli isolated from food animals in China over a ten-year period. From 2003 to 2012, 2815 E. coli isolates collected from diseased animals (chickens, pigs, and waterfowl) were screened for the prevalence of CTX-M genes.(More)
Infections with influenza A viruses are still a major threat to humans and several animal species. The occurrence of highly pathogenic avian influenza viruses capable of infecting and killing humans highlights the urgency for a new and efficient strategy for the treatment of diseases caused by the virus. Andrographolide and its derivatives have been widely(More)
Escherichia coli isolates from diseased pigs were examined for antimicrobial susceptibility to 12 antimicrobials and possession of virulence genes (VGs), and then grouped according to the phylogenetic background and genetic relatedness. Associations between antimicrobial resistance (AMR) and VGs and between AMR and phylogenetic group were subsequently(More)
ETHNOPHARMACOLOGICAL RELEVANCE The root of Scutellaria baicalensis Georgi, also called Huangqin in China, is an herbal-based nutraceutical which is usually used in Chinese medicated diet (CMD). As an abundant ingredient in Huangqin, wogonoside is a flavonoid glycoside. The present work investigated the anti-inflammatory activities of wogonoside in(More)
One hundred two pathogenic Escherichia coli isolates from diseased pigs were analyzed for serotypes, virulence genes, antimicrobial susceptibility, and the molecular basis of phenicol resistance. Of these 102 E. coli isolates, 101 were typeable and belonged to 27 different O serogroups. However, 69% of these isolates belonged to one of the following eight(More)
OqxAB has recently been identified as one of the mechanisms of plasmid-mediated quinolone resistance (PMQR). Compared to what is observed for other PMQR determinants, there is a paucity of data with regard to the prevalence and epidemiology of OqxAB and its contribution to resistance to different antimicrobials. In this study, the prevalence and(More)
Avian pathogenic Escherichia coli (APEC) is an important respiratory pathogen of poultry. A variety of virulence-associated genes and serogroups are associated with avian colibacillosis caused by APEC strains. One hundred forty-eight E. coli isolates recovered from diagnosed cases of avian colibacillosis from Guangdong province between 2005 and 2008 were(More)
