Florfenicol is a broad spectrum antibacterial, licensed globally for treatment of animal and aquaculture diseases. In the EU, Canada and US it is not permitted for use in animals producing milk or eggs. There are no published methods for analysis of total florfenicol content in milk/milk products...

Large quantities of the antibiotic florfenicol are used in animal farming and aquaculture, contaminating the ecosystem with antibiotic residues and promoting antimicrobial resistance, ultimately leading to untreatable multidrug-resistant pathogens. Florfenicol-resistant bacteria often activate...

To understand the antibiotic resistance of Escherichia coli from cattle in some areas of Jiangsu province and to investigate the prevalence of bla_CTX-M, 159anal swab samples from dairy cows, 121anal swab samples and feces samples from beef cattle were collected in 2019, Jiangsu. E.coli were...

Bovine mastitis is the most important disease of dairy herds worldwide. Its main etiologic agents are bacteria, including Streptococcus agalactiae. The importance of this agent in bovine mastitis is because it is highly contagious and has a high impact on the occurrence of clinical mastitis cases...

The persistence of florfenicol residues in milk and their migration to dairy products was investigated following treatment of six lactating dairy cows with Selectan 300 mg mL^-1 solution for injection at a dose of 1 mL 15 kg body weight^-1. Florfenicol residues were measurable (LOQ 1.0 µg kg^-1) in...

Background: This study describes the occurrence of antimicrobial resistance (AMR) in commensal Escherichia coli and Enterococcus/Streptococcus spp. (ES) isolated from fecal samples of dairy cows and assesses the variation of AMR profiles across regions and seasons following the implementation of...

There is limited epidemiological knowledge on udder health in Upper Egypt dairy cattle and buffaloe that would aid in a pro-active approach towards mastitis prevention. The study objectives were to investigate the prevalence rate of clinical mastitis for dairy bovine animals ownered by small...

Bovine mastitis is still a problem, both in terms of economic losses, animal health and welfare the increased risk of human health. Based on these affirmations, the purpose of the study was to establish the prevalence of the main etiological agents involved in the pathogenesis of bovine mastitis,...

While ongoing surveillance and research initiatives have provided some information on antimicrobial use (AMU) in many livestock commodities, there are no recent reports for Canadian cow-calf herds. Antimicrobial use data were collected in 2014 for bulls, cows, and calves from 100 herds...

A reliable liquid chromatography-tandem mass spectrometry method was developed to determine total florfenicol residues in bovine tissues and eel. Florfenicol and its metabolites (florfenicol amine, monochloroflorfenicol, florfenicol oxamic acid, and florfenicol alcohol) were analyzed as the marker...
