Prevention and control of clustered infections appear key to containing antimicrobial resistance. (cdc.gov)
There also is a need to monitor for potential adverse consequences of intrapartum antibiotic prophylaxis (e.g., emergence of bacterial antimicrobial resistance or increased incidence or severity of non-GBS neonatal pathogens). (cdc.gov)
Antibiotic1
Other named constituents of natural Penicillium, such as penicillin A, were subsequently found not to have antibiotic activity and are not chemically related to antibiotic penicillins. (wikipedia.org)
Bacteria2
They are still widely used today for different bacterial infections, though many types of bacteria have developed resistance following extensive use. (wikipedia.org)
Several semisynthetic penicillins are effective against a broader spectrum of bacteria: these include the antistaphylococcal penicillins, aminopenicillins, and antipseudomonal penicillins. (wikipedia.org)
Neonatal1
Fleming's student Cecil George Paine was the first to successfully use penicillin to treat eye infection (neonatal conjunctivitis) in 1930. (wikipedia.org)
Streptococcus1
After 7-valent pneumococcal conjugate vaccine (PCV) for children was introduced in Japan in November 2010, we examined changes in Streptococcus pneumoniae serotypes and in genetic antimicrobial drug resistance of isolates from adults with invasive pneumococcal diseases. (cdc.gov)
Active3
Like most natural products, penicillin is present in Penicillium moulds as a mixture of active constituents (gentamicin is another example of a natural product that is an ill-defined mixture of active components). (wikipedia.org)
The principal active components of Penicillium are listed in the following table: Other minor active components of Penicillium include penicillin O, penicillin U1, and penicillin U6. (wikipedia.org)
In the activated state of the complex, the inhibitory helix of EnvC is released, freeing it to associate with the RH of AmiB, which liberates its active site for PG cleavage. (bvsalud.org)
Pneumococcal strains1
While a variety of SNPs in the capsular operon are not meaningful, biofilm-derived pneumococcal strains have been detected with key mutations in this operon. (medscape.com)
Other named constituents of natural Penicillium, such as penicillin A, were subsequently found not to have antibiotic activity and are not chemically related to antibiotic penicillins. (wikipedia.org)
Serotype1
[ 38 ] It is likely that when future clinically relevant 'nontypeable' strains are detected in natural populations, sequencing the fragment between dexB and the aliA genes will provide insight into whether this strain would have been of a known serotype if not for a mutation in a type-specific capsular gene. (medscape.com)
Antimicrobial4
The term "penicillin" is defined as the natural product of Penicillium mould with antimicrobial activity. (wikipedia.org)
In modern usage, the term penicillin is used more broadly to refer to any β-lactam antimicrobial that contains a thiazolidine ring fused to the β-lactam core and may or may not be a natural product. (wikipedia.org)
After 7-valent pneumococcal conjugate vaccine (PCV) for children was introduced in Japan in November 2010, we examined changes in Streptococcus pneumoniae serotypes and in genetic antimicrobial drug resistance of isolates from adults with invasive pneumococcal diseases. (cdc.gov)

Clinical4
A recent clinical report has linked Streptococcus pyogenes β-lactam antibiotic resistance to mutation in the penicillin binding protein (PBP) PBP2x. (nih.gov)
Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation and then purified. (wikipedia.org)
A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G (intramuscular or intravenous use) and penicillin V (given by mouth). (wikipedia.org)
Together, these data provide the molecular basis of resistance of clinical E. faecium PBP5 variants, results that are likely applicable to the PBP family. (bvsalud.org)
Infections2
Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. (wikipedia.org)
They are still widely used today for different bacterial infections, though many types of bacteria have developed resistance following extensive use. (wikipedia.org)
Main1
When phenoxyethanol or phenoxyacetic acid are added to the culture medium, the mould produces penicillin V as the main penicillin instead. (wikipedia.org)
Results2
Ten percent of the population claims penicillin allergies but because the frequency of positive skin test results decreases by 10% with each year of avoidance, 90% of these patients can eventually tolerate penicillin. (wikipedia.org)
Thus, reducing sidechain bulkiness and expanding surface loops results in increased dynamics that facilitates acyl-enzyme hydrolysis and, via increased ß-lactam antibiotic turnover, facilitates ß-lactam resistance. (bvsalud.org)
