Meningococcal Antibiotic Resistance: Molecular Characterization of Isolates from Patients with Invasive Meningococcal Disease (IMD) in Greece

Antibiotics, 2023
For effective case management and chemoprophylaxis of Invasive Meningococcal Disease (IMD), prompt antibiotic treatment is required. N. meningitidis is usually susceptible to antibiotics, but reduced susceptibility to penicillin, ciprofloxacin, and ...

Restricted Sequence Variation in Streptococcus pyogenes Penicillin Binding Proteins

mSphere, 2020
A recent clinical report has linked Streptococcus pyogenes β-lactam antibiotic resistance to mutation in the penicillin binding protein (PBP) PBP2x. To determine whether this is an isolated case or reflects a broader prevalence of mutations that might ...

Global spread of carbapenem-resistant Enterobacteriaceae: Epidemiological features, resistance mechanisms, detection and therapy.

Microbiology Research, 2022
Bacterial drug resistance has become a global public health threat, among which the infection of carbapenem-resistant Enterobacterales (CRE) is one of the top noticeable issues in the global anti-infection area due to limited therapy options.

Antibiotic resistance among invasive Neisseria meningitidis isolates in England, Wales and Northern Ireland (2010/11 to 2018/19).

PLoS ONE, 2021
Invasive meningococcal disease (IMD), caused by Neisseria meningitidis, can have a fatality rate as high as 10%, even with appropriate treatment. In the UK, penicillin is administered to patients in primary care whilst third generation cephalosporins ...

Penicillin Resistant Staphylococci

Experimental Biology and Medicine, 1945
Summary(1) In a study of the susceptibility of 115 strains of staphylococci to penicillin 16 or 13.9% were found to be resistant. (2) All strains resistant to penicillin produced penicillinase; none of the susceptible strains had this property. (3) Many of the penicillinase-producing staphylococci produce coagulase indicating the importance of the ...

Antimicrobial Resistance with Streptococcus pneumoniae in the United States, 1997–98

Emerging Infectious Diseases, 1999
From November 1997 to April 1998, 1,601 clinical isolates of Streptococcus pneumoniae were obtained from 34 U.S. medical centers. The overall rate of strains showing resistance to penicillin was 29.5%, with 17.4% having intermediate resistance. Multidrug

Antibiotic resistance in the environment, with particular reference to MRSA [PDF]

, 2008
The introduction of β-lactam antibiotics (penicillins and cephalosporins) in the 1940s and 1950s probably represents the most dramatic event in the battle against infection in human medicine.

Drug-resistance in Streptococcus pneumoniae isolates among Spanish middle aged and older adults with community-acquired pneumonia

BMC Infectious Diseases, 2009
Background Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns.
