Penicillin Resistance of Nonvaccine Type Pneumococcus before and after PCV13 Introduction, United States [PDF]
Emerging Infectious Diseases, 2017 Introduction of 13-valent pneumococcal conjugate vaccine in the United States was not associated with a significant change in prevalence of penicillin resistance in nonvaccine type serotypes because of the variable success of highly resistant serotypes ...

The effect of MurM and a branched cell wall structure on penicillin resistance in Streptococcus pneumoniae [PDF]
Journal of BacteriologyThe aminoacyltransferase MurM is an important penicillin resistance determinant in Streptococcus pneumoniae. This enzyme attaches a serine or alanine to the side chain of lysine, the third residue of the pentapeptide of lipid II, resulting in branched ...

Association between treatment failure in patients with early syphilis and penicillin resistance-related gene mutations of Treponema pallidum: Protocol for a multicentre nested case–control study [PDF]
Frontiers in Medicine, 2023 BackgroundThe widespread occurrence of syphilis remains a global public health problem. Although penicillin has been recommended as the first-line therapy for syphilis for more than 70 years, treatment failure occurs in 10–20% of patients with early ...

Analysis of Whole-Genome Sequences for the Prediction of Penicillin Resistance and β-Lactamase Activity in
mSystems, 2018 Penicillin (PEN) is a low-cost option for anthrax treatment, but naturally occurring resistance has been reported. β-Lactamase expression (bla1, bla2) in Bacillus anthracis is regulated by a sigma factor (SigP) and its cognate anti-sigma factor (RsiP ...
