The antibacterial activity and selection of resistant bacteria, along with mechanisms of fluoroquinolone resistance, were investigated by integrating the static [MIC or mutant-prevention concentration (MPC)] and in vitro dynamic model approaches using Escherichia coli isolates from diseased dogs. Using the dynamic models, selected E. coli strains and(More)
In the present study, we confirmed the ability of M. hyopneumoniae to induce the secretion of large amount of proinflammatory cytokine and nitric oxide (NO) in murine macrophage RAW 264.7 cells. Moreover, M. hyopneumoniae-induced activation of the MAPK and NF-кB pathways by phosphorylation of ERK1/2, p38 and JNK/SAPK and by dissociation of IκB from NF-κB.(More)
Subacute toxicity and immunopharmacological activities of β-glucan from P. polymyxa JB115 was evaluated in a 28-day feeding study in rats. The white blood cell count, red blood cell count, hematocrit, hemoglobin, thrombocytes (THR) and thrombocytocrit were significantly higher in male fed with β-glucan than control rats and the insignificant lower(More)
In the present study, a computational comparative and subtractive genomic/proteomic analysis aimed at the identification of putative therapeutic target and vaccine candidate proteins from Kyoto Encyclopedia of Genes and Genomes (KEGG) annotated metabolic pathways of Mycoplasma hyopneumoniae was performed for drug design and vaccine production pipelines(More)
The antibacterial activity, selection of Escherichia coli (E. coli) mutants and mechanisms of fluoroquinolone resistance were investigated by integrating the minimum inhibitory concentration (MIC), mutant prevention concentration (MPC) and in vitro dynamic model approaches. Difloxacin and orbifloxacin, for which the above information has been scarce, were(More)
The in vitro activity of 15 antimicrobial agents against clinical isolates of Staphylococcus pseudintermedius, Staphylococcus aureus, Escherichia coli, Pasteurella spp. and Streptococcus canis from dogs was investigated. For Staphylococcus spp., the highest frequency of resistance was observed for penicillin, followed by ampicillin, tetracycline and(More)
AIM To investigate the mechanism by which Mycoplasma hyopneumoniae induces inflammatory responses in murine alveolar macrophage (MH-S) cells. METHODS A pathogenic strain of M. hyopneumoniae cultured in modified Friis medium was used to investigate the inflammatory response in MH-S cell lines. The effect of stimulation by M. hyopneumoniae on the production(More)
Obesity, a rapidly growing threat to human health worldwide, is responsible for a large proportion of the total burden of disease. Therefore, obesity control could be a vital scheme to prevent many diseases. The aim of this study was to examine the activities and mechanism of Auricularia auricula-judae 70% ethanol extract (AAE) in preventing hypolipidemic(More)
The present study investigated the anti-inflammatory effects of dichloromethane extract of Auricularia auricula-judae. Dichloromethane extract of Auricularia auricula-judae inhibited Lipopolysaccharide (LPS) -induced nitric oxide (NO) production significantly in a dose-dependent manner in the concentration ≥10 μg/ml (p < 0.05) . Furthermore, RT-PCR results(More)
The aim of this study was to determine the efficacy of dietary administration of Lactobacillus pentosus PL11 on growth performance and the immune and antioxidant systems in Japanese eel Anguilla japonica challenged with Edwardsiella tarda. A total of 75 Japanese eels (24.63±0.83 g) were grouped into 5 treatment diets which were a control diet (C) without E.(More)
