penicillin

noun pɛnɪˈsɪlɪnˌpɛnəˈsɪlən

mass noun

1An antibiotic or group of antibiotics produced naturally by certain blue moulds, now usually prepared synthetically. Penicillin was discovered in 1928 and during the Second World War became the first antibiotic to be used by doctors.
patients who are allergic to penicillin
count noun penicillins and cephalosporins
Example sentencesExamples
- Most antibiotics such as penicillins, cyclosporines, and aminoglycosides can be used safely during pregnancy, but tetracyclines should be avoided.
- The aminopenicillins were the first penicillins discovered to be active against gram-negative rods such as E. coli and H. influenzae.
- While the incidence of true cross-reactivity between penicillins and cephalosporins is low, the possible reactions include anaphylaxis, which can be fatal.
- Within these two therapeutic drug classes, penicillins were identified 22 times, cephalosporins 21 times, and opioids 20 times.
- The antibiotics used were mainly cephalosporins, penicillins, fluoroquinolones, aminoglycosides, tetracyclines and antituberculosis drugs.
- Studies from the late 1960s and the 1970s revealed that streptococcal eradication was equal with intramuscularly and orally administered penicillins.
- The surprising finding was that people who had reacted to sulphonamides were more likely to react to penicillins than to sulphonamide non-antibiotics.
- Exanthematous eruptions most commonly occur in association with the administration of penicillins or cephalosporins.
- Oral antibiotics are usually used in the treatment and include first-generation cephalosporins, penicillinase-resistant penicillins, macrolides, and fluoroquinolones.
- Enterococci are inherently resistant to cephalosporins, semi-synthetic penicillins, and clindamycin.
- For the patient who is allergic to penicillins, the use of trimethoprim/sulfamethoxazole is indicated.
- Many were originally sensitive to antibiotics such as penicillins, but overuse of these drugs has resulted in many multi-resistant bacteria.
- In general, cephalosporins and penicillins are not very effective in treating acne.
- The lactams are a family of antimicrobial agents consisting of four major groups: penicillins, cephalosporins, monobactams, and carbapenems.
- Overuse of antibiotics has been shown to drive the evolution of mutant strains of bacteria immune to a broad spectrum of drugs, including penicillins, cephalosporins, and quinolones.
- Major classes of antibiotics include tetracyclines, aminoglycosides, penicillins, cephalosporins, fluoroquinolones, streptogramins, sulfonamides, and erythromycins.
- Unlike Streptococcus pneumoniae, group A beta-hemolytic streptococci have not developed resistance to penicillins.
- All the usual range of antibiotics, penicillins and cephalosporins are pretty much useless against these things.
- It is well established that far less expensive antibiotics, including the penicillins and tetracyclines, are highly effective against Anthrax.
- Antibiotic categories to consider include penicillins, cephalosporins, and macrolides.
2A blue mould of a type that produces penicillin.
Genus Penicillium, subdivision Deuteromycotina

Origin

From the modern Latin genus name Penicillium (see penicillium) + -in¹.

pen from Middle English:
The earliest pens for writing were made from a feather with its quill sharpened and split to form a nib which was dipped in ink. The origin of pen reflects this, going back to Latin penna ‘feather’. The idea that the pen is mightier than the sword appeared in the works of the Latin author Cicero in the 2nd century bc. The origin of Old English pen in the sense of an animal enclosure is not known. See also panache, pin
