The emergence of extended- spectrum β-lactamase (ESBL) is the underlying cause of growing antibiotic resistance among Gram-negative bacteria to β-lactam antibiotics. We recently reported the discovery of honey glycoproteins (glps) that exhibited a rapid, concentration-dependent antibacterial activity against both Gram-positive Bacillus subtilis and Gram-negative Escherichia coli that resembled ...

This manuscript describes the synthesis of new Au(I) and Ag(I) complexes with aminophosphane ligands and a study of their antibacterial activity against Gram-negative Salmonella enterica serovar typhimurium and Escherichia coli and Gram-positive Listeria monocytogenes and Staphylococcus aureus. The bactericidal assays revealed the effectiveness of these compounds on paradigm Gram-negative and G...

ObjectivesTo determine the safety and efficacy of bedaquiline for Chinese patients with multidrug-resistant tuberculosis (MDR-TB) based on serum concentration monitoring to identify factors associated QTc prolongation occurring during treatment.MethodsData were collected from 35 who received treatment regimens containing MDR-TB May 2018 December 2020. Blood samples collected, concentrations mea...

BACKGROUND Cassia fistula, is a flowering plant and a member of Fabaceae family. Its leaves are compound of 4 - 8 pairs of opposite leaflets. There are many Cassia species around the world which are used in herbal medicine. OBJECTIVES This study was designed to examine in vitro anti-bacterial activity of methanolic and ethanolic extracts of C. fistula native to Khuzestan, Iran. MATERIALS AN...

The rise of multidrug resistant microbial species is a major public health problem worldwide. Complementary natural sources with antimicrobial potentials including plants and plant-based products such as honey, are currently receiving great attention. As such, this study aimed to evaluate the medicinal honey by testing its antibacterial efficacy against Pseudomonas aeruginosa isolates associate...

Objective(s): Plasmid-mediated quinolone resistance (PMQR) determinants and integrons have a considerable contribution to bacterial drug resistance in Gram-negative pathogens. We studied the prevalence of PMQR genes and integron carriage in multidrug-resistant community isolates of Klebsiella spp.Materials and Methods: Two hundred and fi...

Through bioassay-guided fractionation of the extracts from the aerial parts of the Chinese herb Hypericum japonicum Thunb. Murray, Isojacareubin (ISJ) was characterized as a potent antibacterial compound against the clinical methicillin-resistant Staphylococcus aureus (MRSA). The broth microdilution assay was used to determine the minimal inhibitory concentrations (MICs) and minimal bactericida...

conclusions this study indicates that satureja khuzestaniea essence has inhibitory effects on the gene expression of antibiotic resistance in bla-oxa-23 that has a high mic. given that this essence has a good inhibitory effect on gene expression in mdr acinetobacter baumannii and bla-oxa-23, the results indicate that it could be used as a natural way to prevent the growth of acinetobacter bauma...

conclusions regarding clinical and laboratory standards institute (clsi) definition for vancomycin susceptibility (mic < 2 μg/ml), it seems that vancomycin may not be considered as the best antibiotic in order to treat heteroresistant vancomycin intermediate s. aureus (hvisa) and vancomycin sensitive s. aureus (vssa) infections, and a new breakpoint for vancomycin and alternative antibiotics sh...
