Penicillin molecules are small enough to pass through the spaces of glycoproteins in the cell wall. For this reason Gram-positive bacteria are very susceptible to penicillin (as first evidenced by the discovery of penicillin in 1928 [46]). [47] Penicillin, or any other molecule, enters Gram-negative bacteria in a different manner. The bacteria ...
In molecular biology, carbenicillin may be preferred as a selecting agent (see plasmid stabilisation technology) because its breakdown results in byproducts with a lower toxicity than analogous antibiotics like ampicillin. Carbenicillin is more stable than ampicillin and results in fewer satellite colonies on selection plates.
Benzylpenicillin, also known as penicillin G (PenG [4]) or BENPEN, [5] is an antibiotic used to treat a number of bacterial infections. [6] This includes pneumonia, strep throat, syphilis, necrotizing enterocolitis, diphtheria, gas gangrene, leptospirosis, cellulitis, and tetanus. [6] It is not a first-line agent for pneumococcal meningitis. [6]
Phenoxymethylpenicillin, also known as penicillin V (PcV) and penicillin VK, is an antibiotic useful for the treatment of a number of bacterial infections. [2] Specifically it is used for the treatment of strep throat , otitis media , and cellulitis . [ 2 ]
Benzathine benzylpenicillin, also known as benzathine penicillin G (BPG), is an antibiotic medication useful for the treatment of a number of bacterial infections. [3] Specifically it is used to treat strep throat , diphtheria , syphilis , and yaws .
It is a form of penicillin which is a salt of benzylpenicillin and the local anaesthetic agent procaine. [9] The salt has weak solubility, and is prepared as a suspension. Upon injection it forms a deposit within tissue (a "depot'), and the salt slowly dissolves into interstitial fluid - dissociating the two molecules into their bioactive forms over an extended pe
The side effects of penicillin can be altered by taking other medications at the same time. Taking oral contraceptives along with penicillin may lower the effects of the contraceptive. When probenecid is used concurrently with penicillin, kidney excretion of probenecid is decreased resulting in higher blood levels of penicillin in the ...
Cefdinir, sold under the brand name Omnicef among others, is an antibiotic used to treat pneumonia, otitis media, strep throat, and cellulitis. [1] It is a less preferred option for pneumonia, otitis media, and strep throat which may be used in those with a severe penicillin allergy. [1]
