A suitable liquid chromatography quadrupole time-of-flight mass spectrometric (LC–Q-TOF–MS) method was developed for separation and characterization of related substances in bacitracin test drug. The separation was performed on LiChrospher RP-18 column using methanol as mobile phase A and 0.2%...
Twelve Maghraby camel calves (185.2 ± 0.7 kg body weight, BW) were utilized in a – 14 weeks – completely randomized design experiment to evaluate the effects of feeding a probiotic yeast culture (YC; Diamond V® “XP” YC containing Saccharomyces cerevisiae) or zinc bacitracin (ZnB) on feed in...
This study extends the previous knowledge of the action of bacitracin zinc against xenic cultures of Entamoeba histolytica. Results presented here, using axenic E. histolytica, confirm the enhanced activity of bacitracin zinc as compared to native bacitracin and demonstrate that this enhancement...
This work tested the effect of replacing zinc bacitracin with a blend of caproic and caprylic acids in a diet including colistin on growth performance, mortality, gut histology and development of intestinal lymphoid tissues in rabbits experimentally infected with Escherichia coli and Clostridium...
Bacitracin is a dodecapeptide antibiotic produced by Bacillus sp. The antibacterial activity depends upon the peptide binding a divalent metal. Hitherto, the exact coordination of the cation has not been established. In particular the role played by the sulphur and nitrogen atoms of the thiazoli...
This report describes a case of systemic anaphylaxis to bacitracin zinc ointment in a 24-year-old man who was injured in a motorcycle accident. Extensive abrasions on the patient's extremities were cleaned with Shurclens® before application of viscous Xylocaine™ and bacitracin zinc ointment...
The objective of this study was to evaluate the effects of dietary hops β-acids on the productive performance and intestinal microbiota of broilers challenged with Eimeria acervulina and Eimeria tenella. 1440 broiler chicks were allocated in a randomized design with 6 treatments and 6 replicate...
Palladium nanomaterials have attracted great attention on the development of electrocatalysts for fuel cells. Herein, we depicted a novel strategy in the synthesis of palladium nanoparticles with superior electrocatalytic activity. The new approach, based on the self-assembly of bacitracin biote...
ABSTRACTOne hundred and seven Streptococcus suis isolates were collected from healthy pigs or asymptomatic carriers in Jiangsu, China in 2016–2017. Thirty-eight percent of the isolates were linezolid-resistant and all carried the optrA gene. Among them, one isolate, SFJ44, was resistant to all ...
Properties of microbicide drugs are believed to be associated to their interactions with biointerfaces such as cell membranes, encouraging research on the identification of membrane sites capable of drug binding. In this study, we investigated the interaction of bacitracin, a known antibiotic pe...
Bacitracin immobilized on the titanium (Ti) surface significantly improves anti-bacterial activity and biocompatibility in vitro. In the current study, we investigated the biologic performance (bactericidal effect and bone-implant integration) of bacitracin-modified Ti in vivo. A rat osteomyelit...
Bacitracin, a widely used metallopeptide antibiotic, has been reported to be locally used in treating wounds without systemic adverse reactions. Our preliminary study showed that bacitracin might enhance the osteogenic differentiation of human bone marrow mesenchymal stem cells (HBMSCs). The pre...
As the widely use of gold nanoparticles (AuNPs) in drug delivery, the precise control on the size and morphology of the AuNPs is urgently required. In this scenario, traditional synthesis methods cannot meet current requirement because of their inherent defects. We have depicted here a novel met...
The bacitracin synthetase gene cluster in Bacillus licheniformis DW2 is composed of the bacABC operon encoding a non-ribosomal peptide synthetase and bacT encoding a thioesterase. Although the bacitracin gene cluster has been well studied, little is known about how this gene cluster is regulated...
Biofilms of methicillin-resistant Staphylococcus aureus (MRSA) have serious clinical implications. However, it is difficult to eradicate MRSA biofilms due to the increased tolerance to antimicrobials of biofilms. In this study, we investigated the synergistic anti-biofilm effect of the combinati...
Wild and cultivated Licorice (Glycyrrhiza uralensis FISCH.) are the main source of licorice. In recent years, wild Glycyrrhiza plants have been seriously damaged and this has reduced the population. The cultivation of Licorice has been the best way to solve the problem of its shortage. The conte...
Postmenopausal osteoporosis, mainly caused by osteoclast-induced bone resorption, has become a global public health burden. Natural compounds are emerging as potential therapeutics for postmenopausal osteoporosis. In vitro osteoclastogenesis assay was conducted to investigate the effect of Glycy...
Diabetic patients are at an increased risk of developing severe and progressive periodontitis. Periodontal disease also increases the severity of diabetes by enhancing insulin resistance. Therefore, the regulation of periodontal inflammation in diabetic patients may contribute to the control of ...
Glycyrrhizic acid (GA), as a traditional herbal, can self-assemble into helical nanofiber in the water. The formed helical nanostructures can be employed as scaffolds for asymmetric Diels-Alder reaction. Through co-assembling with a series of achiral copper-ligands, the chirality of GA helical n...
Glycyrrhizic acid is the main active component of Licorice root which has been known in traditional Chinese and Japanese medicine since ancient times. In these cultures glycyrrhizic acid (GA) is one of the most frequently used drugs. However, only in 21-st century a novel unusual property of the...
