Aims Carbapenem-resistant Acinetobacter baumannii represents a public health problem, and the search for new antibacterial drugs has become priority. Here, we investigate activity of biogenic silver nanoparticles (Bio-AgNPs) synthesized by Fusarium oxysporum, used alone or in combination with polymyxin B against carbapenem-resistant A. baumannii. Methods Results In this study, ATCC® 19606™ strain four strains were used. The Bio-AgNPs its synergism determined using broth microdilution,...
Abstract Aims Antibiotic management of infections caused by Acinetobacter baumannii often fails due to antibiotic resistance (especially carbapenems) and biofilm-forming strains. Thus, the objective here was evaluate in vitro antibacterial antibiofilm activity biogenic silver nanoparticle (Bio-AgNP) combined with meropenem, against multidrug-resistant isolates A. baumannii. Methods results In this study, ATCC® 19606™ four carbapenem-resistant (Ab) strains were used. The Bio-AgNP meropenem...
The Staphylococcus bacteria cause several infections, S. aureus is the major species, expressing different virulence factors. Therefore, coagulase-negative (CoNS) are nosocomial pathogens, mainly associated with biofilm formation in invasive medical devices. Methicillin-resistant (MRSA) and multidrug resistant (MDR) CoNS widely distributed hospital environment, leading to infections that difficult treat. Thus, nanoparticles (NPs) studied as an alternative control of these pathogens. Silver...
Abstract Respiratory bacterial infections are a cause of morbidity and mortality worldwide; most these respond well to antibiotic therapies, although several factors bacteria become increasingly resistant, leading concerning public health problem. Hence, researchers have sought new antibiotics that can replace or enhance the effectiveness existing drugs. Given this scenario, review is based on original articles from PubMed Science Direct databases published May 2015 February 2022 reported...
INTRODUCTION: Eugenia uniflora L. and Psidium cattleianum Sabine essential oils (EO) can be biologically active serve as novel sources of antibiotics for Klebsiella pneumoniae Acinetobacter baumannii bacteria. METHODS: The EO E. (EOE) P. (EOP) were extracted from de leaves the plants chemically characterized by gas chromatography-mass spectrometry (GC-MS). antioxidant potential was evaluated DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) technique cytotoxicity in mammalian VERO cell line MTT...
Abstract Natural products have been touted as important tools because of their vast potential for the development compounds with antimicrobial activity and possible inhibitory and/or adjuvant resistance mechanisms. Propolis has empirically used many years treatment diseases, mainly due to its antioxidant, anti inflammatory activities. This study aimed evaluate in vitro antimycobacterial ethanol extract propolis alone combination rifampicin (RIF), amikacin (AMI) ciprofloxacin (CIP). The...
The objective of this study was to evaluate the antibacterial activity different EOs against Escherichia coli, Salmonella spp., and coagulase-positive staphylococcus isolated from ground beef. had values varying 0.78μl/mL 100μl/mL, essential oil Citrus lemon did not present any bacterial studied strains. For E. Cinnamomum zeylanicum presented best inhibitory (MIC = 1.56μl/mL). In Cymbopogon citratus 12.5μl/mL 25.0μl/mL), C. 25.0 µL/mL) Ocimum basilicum 6.25μl/mL, 50.0μl/mL) exhibited similar...
