Gramicidin P is an antibiotic that is produced by bacteria. The word "Gramicidin" is derived from "Grames", the surname of the scientist who discovered it. The "P" refers to one of the subtypes of Gramicidin. The phonetic transcription of this word would be /ˌɡræmɪˈsaɪdɪn piː/. The "gram" part is pronounced with a hard "g" sound, the "cid" part with a soft "c" sound, and the "pi" at the end is pronounced as the letter "P". This drug is commonly used in topical medications to treat skin infections caused by bacteria.
The word "Gramicidin P" is derived from two components: "Gramicidin" and the letter "P".
"Gramicidin" comes from the Latin word "graminis", meaning "grass", and the Greek word "kidein", meaning "to kill". It was coined in reference to the antibiotic activity of the substance against Gram-positive bacteria. The term was first used by the American microbiologist René Dubos in 1939 to describe a group of antibiotic substances derived from soil bacteria.
The letter "P" in "Gramicidin P" represents one of the variants or subtypes of Gramicidin. Gramicidin P is one of the five known naturally occurring variations of Gramicidin, with each variant being isolated from different sources. These variations are designated as A, B, C, M, and P.
