Resistance of Gram-Positive Bacteria to Current Antibacterial Agents and Overcoming Approaches

Molecules, 2020
The discovery of antibiotics has created a turning point in medical interventions to pathogenic infections, but unfortunately, each discovery was consistently followed by the emergence of resistance. The rise of multidrug-resistant bacteria has generated

Five-year period evaluation of isolated agents and their resistance profiles in intensive care unit patients with malignancy

Journal of Infection in Developing Countries, 2020
Introduction: Patients treated in the intensive care unit (ICU) are usually patients who deteriorated health condition and could have longer hospital stay compared to other patients. Hospital infections are more common in ICU patients.

β-Glucan-Producing Pediococcus parvulus 2.6: Test of Probiotic and Immunomodulatory Properties in Zebrafish Models

Frontiers in Microbiology, 2018
Lactic acid bacteria synthesize exopolysaccharides (EPS), which could benefit the host’s health as immunomodulators. Furthermore, EPS could protect bacteria against gastrointestinal stress, favoring gut colonization, thus protecting the host against ...

Extracellular vesicles: An emerging platform in gram-positive bacteria

Microbial Cell, 2020
Extracellular vesicles (EV), also known as membrane vesicles, are produced as an end product of secretion by both pathogenic and non-pathogenic bacteria.

Conjugation in Gram-Positive Bacteria

Microbiology Spectrum, 2014
ABSTRACT Conjugative transfer is the most important means of spreading antibiotic resistance and virulence factors among bacteria. The key vehicles of this horizontal gene transfer are a group of mobile genetic elements, termed conjugative plasmids. Conjugative plasmids contain as minimum instrumentation an origin of transfer (

Characterization of the Plasmid Encoded Virulence Region pat-1 of Phytopathogenic Clavibacter michiganensis subsp. michiganensis

Molecular Plant-Microbe Interactions, 1997
The tomato pathogen Clavibacter michiganensis subsp. michiganensis NCPPB382, causing bacterial wilt and canker, harbors two plasmids, pCM1 (27.5 kb) and pCM2 (72 kb), carrying genes involved in virulence.

Through the wall: extracellular vesicles in Gram-positive bacteria, mycobacteria and fungi

Nature Reviews Microbiology, 2015
Extracellular vesicles (EVs) are produced by all domains of life. In Gram-negative bacteria, EVs are produced by the pinching off of the outer membrane; however, how EVs escape the thick cell walls of Gram-positive bacteria, mycobacteria and fungi is ...

A predator-prey interaction between a marine Pseudoalteromonas sp. and Gram-positive bacteria

Nature Communications, 2020
Predator-prey interactions play important roles in the cycling of marine organic matter. Here we show that a Gram-negative bacterium isolated from marine sediments (Pseudoalteromonas sp.

Extracellular Vesicle Biogenesis and Functions in Gram-Positive Bacteria

Infection and Immunity, 2020
Extracellular vesicles (EVs) are membrane-derived lipid bilayers secreted by bacteria and eukaryotic cells. Bacterial membrane vesicles were discovered over 60 years ago and have been extensively studied in Gram-negative bacteria. During their production,
