Spherical and rod shaped protoplasts from β-lactam antibiotic treated cultures of Bacillus subtilis [PDF]
Addition of β-lactams to exponentially growing cultures of an autolytically deficient Bacillus subtilis metc3 lyt-2 strain FJ6 caused increase in optical density to stop after 1 h when it had about doubled, and thereafter to remain constant for at least 6 h.

Initiation of murein biosynthesis inEscherichia colicells treated with β-lactam antibiotics [PDF]
The study of the synthesis and accumulation of murein in cells initiating growth in the presence of β-lactam antibiotics indicated: (i) Murein rearrangement contributes substantially to cell enlargement during the first doubling in cell mass; (ii) Penicillin-binding protein 2 has the potential capability to synthesize most, if not all, the new murein ...

NMR spectrometric assay for determining enzymatic hydrolysis of β-lactam antibiotics with bacteria in aqueous solution [PDF]
An application of a nuclear magnetic resonance (NMR) spectrometer for the measurement of β-lactamase activity in clinical material containing bacteria is presented. By means of proton (1H)-NMR, it was easy to measure quantitatively β-lactamase activity in human bacteriuria, without performing any such pretreatment as isolation of bacteria or extraction

Poor penetration through the outer membrane (OM) of Gram-negative bacteria is a major barrier of antibiotic development. While β-lactam antibiotics are commonly used against Klebsiella pneumoniae and Enterobacter cloacae, there are limited data on OM ...

β-lactam Resistance in Pseudomonas aeruginosa: Current Status, Future Prospects
Pseudomonas aeruginosa is a major opportunistic pathogen, causing a wide range of acute and chronic infections. β-lactam antibiotics including penicillins, carbapenems, monobactams, and cephalosporins play a key role in the treatment of P.

Bacterial temporal dynamics enable optimal design of antibiotic treatment. [PDF]
There is a critical need to better use existing antibiotics due to the urgent threat of antibiotic resistant bacteria coupled with the reduced effort in developing new antibiotics.

Remarkable Iodine-Catalyzed Synthesis of Novel Pyrrole- Bearing N-Polyaromatic β-Lactams
Because of their interesting biological properties various methods for the synthesis of substituted pyrroles are described in the literature. However, synthesis of pyrroles fused with a β-lactam ring has not been reported.

High Prevalence of blaOXA-2 and blaOXA-10 Genes in the β-Lactam-Resistant Clinical Isolates of Pseudomonas aeruginosa [PDF]
Background: Increased resistance to β-lactams is one of the most important considerations about Pseudomonas aeruginosa. This study aimed to investigate the prevalence of blaOXA-2 and blaOXA-10 genes in β-lactam-resistant P. aeruginosa.
