Development of tissue conditioner containing cetylpyridinium chloride montmorillonite as new antimicrobial agent: Pilot study on antimicrobial activity and biocompatibility

ConclusionWithin the limitations of this in vitro and in vivo study, the results suggest that the newly developed tissue conditioner containing CPC-Mont has not only excellent antimicrobial properties, but also the same mechanical properties and biocompatibility as tissue conditioners on the market.

Microbial survival in blood is an essential step toward the development of disseminated diseases and blood stream infections. For poultry, however, little is known about the interactions of host cells and pathogens in blood. We established an ex vivo chicken whole-blood infection assay as a tool to analyze interactions between host cells and three model pathogens, Escherichia coli, Staphylococcus aureus, and Candida albicans. Following a systems biology approach, we complemented the experimental measurements with functional and quantitative immune characteristics by virtual infection modeling. All three pathogens were kill...

Abstract Polyketide-terpenoid hybrid compounds are one of the largest families of meroterpenoids, with great potential for drug development for resistant pathogens. Genome sequence analysis of secondary metabolite gene clusters of a phytopathogenic fungus, Bipolaris sorokiniana 11134, revealed a type I polyketide gene cluster, consisting of highly reducing polyketide synthase, non-reducing polyketide synthase, and adjacent prenyltransferase. MS- and UV-guided isolations led to the isolation of ten meroterpenoids, including two new compounds: 19-dehydroxyl-3-epi-arthripenoid A (1) and 12-keto-cochlioquinone A (2). ...

Abstract Six new polyketides aplojaveediins A-F (1-6) were isolated from the endophytic fungus Aplosporella javeedii associated with the host plant Orychophragmus violaceus (Brassicaceae). The structures of the new metabolites were elucidated by analysis of their NMR and MS data. Compound 1 exhibited antifungal activity against the hyphae form of Candida albicans strain ATCC 24433 in the agar plate diffusion assay and the microbroth dilution assay. The kinetic of killing of C. albicans cells for compound 1 was considerably faster than that of the positive control hygromycin B. Compounds 1 and 6 also exhibited mode...

Abstract The present work investigated the effect of camel's fetal fluids on a variety of bacterial and fungal pathogens. Ten samples of camel's amniotic and allantoic fluids were collected aseptically during parturition and their antimicrobial activities were evaluated by disc diffusion method and minimum inhibitory concentration (MIC) assay. The majority of tested pathogens were inhibited by both fluids up to 25% concentration. The fluids showed zones of inhibition ranging from 8 to 30 mm. The most pronounced inhibition was detected for Staphylococcus aureus, Listeria monocytogenes, Klebsiella pneumonia, an...

anzi A series of 34 new pyrimido[2,1-c][1,2,4]triazine-3,4-diones were synthesized and fully characterized using IR, NMR, MS, and microanalytical analysis. In vitro investigation of 12 compounds of this series revealed promising antimicrobial activity of the conjugates 15a and 15f–j that were tagged with electron-withdrawing groups, with sensitivities ranging from 77% to as high as 100% of the positive control. The investigation of antimicrobial activity included Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 6535, Pseudomonas aeruginosa ATCC 27853, and Escherichia coli ATCC 8739 (EC), and fungal st...

Abstract Present work aimed to develop active packaging films based on chitosan (CS), poly (vinyl alcohol) (PVA) and boswellic acid (BA), and to evaluate the effect of BA on multifunctional properties of CS/PVA (CPBA) active films. Different compositions of active packaging films were prepared by the solvent casting method. The results indicated that incorporation of BA enhanced the ultraviolet blocking, morphology, mechanical properties, water solubility and hydrophilicity of the CPBA active films. Significant improvement in the barriers properties of BA incorporated CPBA active films were observed. The microbiol...
