1. SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF NEW Cu (II), Co (II) AND Sn (II) COMPLEXES WITH THE SODIUM HYDROTRIS(2-MERCAPTOTHIAZOLYL)BORATE LIGAND
The emergence of antibiotic resistance among microbial pathogens is a serious public health problem, resulting in a constant need of discovering new antibiotics. For this purpose, we synthetized and determined the antimicrobial activity of copper (Cu), cobalt (Co), and tin (Sn) complexes coordinated with scorpionate ligand in a tridentate mode against microo

2. Evaluation of in vitro activity of ceftolozane-tazobactam against recent clinical bacterial isolates from Brazil - the EM200 study
ABSTRACT Background: The emergence of antibiotic resistance is increasing and there are few effective antibiotics to treat infections caused by resistant and multidrug resistant bacterial pathogens. This study aimed to evaluate the in vitro activity of ceftolozane-tazobactam against clinical bacterial isolates from Brazil. Methods: A total of 673 Gram-nega

3. Post-neurosurgical meningitis caused by KPC-producing Klebsiella pneumoniae: report of two cases
ABSTRACT Nosocomial bacterial infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) is associated with high mortality in neurosurgical patients. There are few reports in the literature on meningitis caused by CRKP. We report two cases of CRKP meningitis after neurosurgery. The K. pneumoniae identification and antimicrobial susceptibility tes

4. Multidrug-resistant Candida glabrata strains obtained by induction of anidulafungin resistance in planktonic and biofilm cells
Candida glabrata has emerged as a common cause of serious life-threatening fungal infections, largely owing to their low susceptibility to azole antifungals. Recent guidance indicates the use of echinocandins as the first-choice drug for the treatment of systemic infections of C. glabrata; however, C. glabrata resistance to echinocandins is reportedly increa

5. Anti-Helicobacter pylori and Anti-inflammatory Properties of Eugenia uniflora L.
Abstract Helicobacter pylori is a bacterium that reaches half of the world population and it’s recognized as the main cause of chronic gastritis and peptic ulcer. In this study, we evaluated the anti-H. pylori, antioxidant and immunomodulatory activities of the methanolic (MeOH) extract of Eugenia uniflora leaves and chemical profile. Anti-H. pylori activi

7. Synthesis, characterization and antimicrobial activity of Cr (III), Co (II) and Ni (II) complexes with 2-thiazoline-2-tiol derivative ligands against bacteria and yeasts of clinical importance
Abstract: Four novel Cr (III), Co (II) and Ni (II) complexes with 2-thiazoline-2-tiol derivative ligands were synthesized and characterized using elemental, physiochemical, and spectroscopy analytical methods. The results showed the formation of ligands coordinated by sulfur atoms of the C = S bond to the L1 ligand and by the sulfur atom of the C-S bond and/

8. Emerging carbapenem-resistant Aeromonas spp. infections in Cali, Colombia
ABSTRACT Introduction: Aeromonas species are renowned enteric pathogens with virulence determinants linked to human diseases, such as gastroenteritis, skin, soft-tissue and muscle infections, and septicemia. A recent concern of resistance in this organism has emerged, especially the presence carbapenemases. Herein we describe a case series of emerging carba

10. Antifungal activity of some Sternbergia taxa: effects on germ tube and biofilm formation
Natural products are rapidly becoming the primary sources of novel antimicrobial agents, as resistance to existing antimicrobial agents is increasing. Apart from determining the antimicrobial activity of natural products, it is also important to understand their effects on the virulence factors of microorganisms. This study aimed to determine the antimicrobi
