Haemophilus parasuis, the causative agent of Glasser's disease, is a pathogen that colonizes the upper respiratory tract (URT) of pigs, invades the bloodstream and causes polyserositis. Because antimicrobials are highly effective against H. parasuis, we hypothesized that they could have a detrimental effect on the establishment of an immune response if given at the time of URT colonization. In ...

Staphylococcus aureus infection is a common cause of mastitis, reducing milk yield, affecting animal welfare and causing huge economic losses within the dairy industry. In addition to the problem of acquired drug resistance, bacterial invasion into udder cells and the formation of surface biofilms are believed to reduce antibiotic efficacy, leading to treatment failure. Here, we investigated th...

Respiratory disease and diarrhea are the 2 most common diseases that result in the use of antimicrobial drugs in preweaned calves. Because the use of drugs in food animals, including dairy calves, has the potential for generating cross-resistance to drugs used in human medicine, it is vital to propose farm practices that foster the judicious use of antimicrobials while assuring animal health an...

The antibiotic resistance of Klebsiella pneumoniae has become a global health concern, leading in reduction the efficacy various medications. This study seeks to determine K. isolated from cats hospitalized Depok veterinary clinics. Surveys, sample collection, isolation, identification, and susceptibility testing comprised research technique. Seven isolates were discovered. There seven cefotaxi...

Objective- Because little information was available in the literature about the angiogenic property of enrofloxacin, this investigation was undertaken to evaluate this aspect using an in vivomodel. Design- Experimental study. Animals- Twenty fertile chicken eggs (Ross 308) with the average egg-weight of 55 ± 0.4 g were rand...

Fluoroquinolones (FQs) are important antibiotics used for treatment of Salmonella infection in poultry in many countries. However, oral administration of fluoroquinolones may affect the composition and abundance of a number of bacterial taxa in the chicken intestine. Using 16S rRNA gene sequencing, the microbial shifts in the gut of Salmonella infected chickens in response to enrofloxacin treat...

Received: Revised: Accepted: Published online: June 07, 2017 August 10, 2017 August 12, 2017 September 23, 2017 The gastrointestinal tract of poultry is inhabited by a diverse community of bacteria, fungi, protozoa and viruses. The aim of the study was to determine the influence of early antimicrobial treatment on the fungal microflora of the gastrointestinal tract of turkeys and analyze candid...

The ability of Mycoplasma synoviae, an avian pathogen, to persist despite fluoroquinolone treatments was investigated in hens. Groups of Mycoplasma-free hens were experimentally infected with the M. synoviae 317 strain and treated twice with enrofloxacin at the therapeutic dose. The results show that the two treatments did not have any influence on this strain of M. synoviae recovery from trach...

Mycoplasma gallisepticum is the major mycoplasmal pathogen in poultry. The present study was undertaken to evaluate the efficacy of six commonly used antimicrobials, including difloxacin, enrofloxacin, ciprofloxacin, doxycycline, gentamicin, and valnemulin, against Mycoplasma gallisepticum, using a Monte Carlo simulation based on the pharmacokinetics-pharmacodynamic (PKPD) theory. The ratio of ...
