Harnessing Gram‐negative bacteria for novel anti‐Gram‐negative antibiotics [PDF]

Microbial Biotechnology
Natural products have proven themselves as a valuable resource for antibiotics. However, in view of increasing antimicrobial resistance, there is an urgent need for new, structurally diverse agents that have the potential to overcome resistance and treat

Lysis of Gram-Negative Bacteria by Serum [PDF]

Journal of General Microbiology, 1958
The antibacterial property of serum, first reported by Nuttall in 1888, has attracted many investigators and an extensive literature has accumulated. The sera of most mammals tested have been found to possess bactericidal activity, but a notable exception is the mouse, whose serum, apparently through lack of complement, is unable to kill any of a ...

Rational Design of Natural Xanthones Against Gram‐negative Bacteria [PDF]

Advanced Science
Most antibiotics are ineffective against Gram‐negative bacteria owing to the existence of the outer membrane (OM) barrier. The rational design of compounds to expand their antibacterial spectra of antibiotics solely targeting Gram‐positive pathogens ...

Geographical differences of carbapenem non-susceptible Enterobacterales and Acinetobacter spp. in Germany from 2017 to 2019

Antimicrobial Resistance and Infection Control, 2022
Background Since May 2016, infection and colonisation with carbapenem non-susceptible Acinetobacter spp. (CRA) and Enterobacterales (CRE) have to be notified to health authorities in Germany. The aim of our study was to assess the epidemiology of CRA and

Environmental microbial communications in gram-positive and gram-negative bacteria [PDF]

Global Journal of Environmental Science and Management, 2023
Microorganisms are present in nature and shape an enormous a half of our micro- and macro-environment. Quorum sensing is the process of intercellular conversation that enables microbes to perceive their surroundings and change their behaviour, allowing ...

In Vitro Activity of Cefiderocol against Clinical Gram-Negative Isolates Originating from Germany in 2016/17

Antibiotics, 2023
Antimicrobial resistance poses a global threat to public health. Of great concern are Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacterales with resistance to carbapenems or third-generation cephalosporins. The aim of the present study was

Interactions between Avibactam and Ceftazidime-Hydrolyzing Class D β-Lactamases

Biomolecules, 2020
Class D β-lactamases exhibit very heterogeneous hydrolysis activity spectra against the various types of clinically useful β-lactams. Similarly, and according to the available data, their sensitivities to inactivation by avibactam can vary by a

Predatory Bacteria: A Potential Ally against Multidrug-Resistant Gram-Negative Pathogens [PDF]

, 2013
Multidrug-resistant (MDR) Gram-negative bacteria have emerged as a serious threat to human and animal health. Bdellovibrio spp. and Micavibrio spp. are Gram-negative bacteria that prey on other Gram-negative bacteria.
