Low beta-lactamase-negative ampicillin-resistant Haemophilus influenzae strains are best detected by testing amoxicillin susceptibility by the broth microdilution method [PDF]

, 2008
Ampicillin resistance in Haemophilus influenzae due to alterations in penicillin-binding proteins (beta-lactamase negative ampicillin resistant [BLNAR]) is acquiring increasing clinical and epidemiological importance.

Aztreonam–avibactam: The dynamic duo against multidrug‐resistant gram‐negative pathogens

Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, Volume 44, Issue 12, Page 927-938, December 2024.
Abstract Antimicrobial resistance poses a significant public health challenge, particularly with the rise of gram‐negative hospital‐acquired infections resistant to carbapenems. Aztreonam–avibactam (ATM–AVI) is a promising new combination therapy designed to combat multidrug‐resistant (MDR) gram‐negative bacteria, including those producing metallo‐β ...

In Vivo Cross‐Linking Sheds Light on the Salmonella Divisome in Which PBP3 and PBP3SAL Compete for Occupancy

Molecular Microbiology, Volume 122, Issue 5, Page 797-818, November 2024.
Salmonella encodes two peptidoglycan synthases, PBP3 and PBP3SAL, which can promote cell division independently. This study shows by in vivo cross‐linking and proteomics that PBP3 and PBP3SAL do not interact in the division complex and that ~40 proteins may associate direct or indirectly to these enzymes, including expected divisome components and new ...

ZipA Is Required for Recruitment of FtsK, FtsQ, FtsL, and FtsN to the Septal Ring in Escherichia coli [PDF]

, 2002
The septal ring in Escherichia coli consists of at least nine essential gene products whose order of assembly resembles a mostly linear dependency pathway: FtsA and ZipA directly bind FtsZ polymers at the prospective division site,

Molecular epidemiology of nontypeable haemophilus influenzae causing community-acquired pneumonia in adults [PDF]

Nontypeable Haemophilus influenzae (NTHi) is an opportunistic pathogen which causes a variety of respiratory infections. The objectives of the study were to determine its antimicrobial susceptibility, to characterize the b-lactam resistance, and to ...

Peptidoglycan Endopeptidase PBP7 Facilitates the Recruitment of FtsN to the Divisome and Promotes Peptidoglycan Synthesis in Escherichia coli

Molecular Microbiology, Volume 122, Issue 5, Page 743-756, November 2024.
The peptidoglycan (PG) hydrolase PBP7 localizes to both the lateral cell envelope and midcell in Escherichia coli, and its midcell localization is dependent on an active divisome. PBP7 influences the timing of FtsZ and FtsN assembly within the divisome. In the absence of PBP7, FtsN assembly is slower and septal PG synthesis is reduced in the absence of

Ampicillin-resistant non-beta-lactamase-producing Haemophilus influenzae in Spain:recent emergence of clonal isolates with increased resistance to cefotaxime and cefixime [PDF]

, 2007
The sequence of the ftsI gene encoding the transpeptidase domain of penicillin-binding protein 3 (PBP 3) was determined for 354 nonconsecutive Haemophilus influenzae isolates from Spain; 17.8% of them were ampicillin susceptible, 56% were beta-lactamase ...
