Penicillin and streptomycin.

add penicillin and streptomycin (Pen-Strep). Primocin® provides maximum protection against microbial contamination with minimal cytotoxicity as it acts on targets found only in microorganisms. Primocin® is composed of four compounds, of which three act on mycoplasmas, Gram-positive and Gram-negative bacteria.In veterinary medicine, streptomycin is the first-line antibiotic for use against gram negative bacteria in large animals ( horses, cattle, sheep, etc.).

Penicillin is an older antibiotic, and it doesn't fight as many types of bacteria as amoxicillin. But they're both possible first-choice options for treating strep throat. Both medications are generally well-tolerated.

Mycoplasmas are considered to be one of the simplest and smallest bacteria. The absence of a rigid cell wall makes them resistant to antibiotics and antibacterial drugs like penicillin and streptomycin. Mycoplasma can pass through filtration methods because of its ability to change shape and the absence of a rigid cell wall.Aminoglycosides = End in “mycin/micin”. Antibiotics belonging to the aminoglycoside class typically end in the suffix “mycin/micin”. Examples of aminoglycosides include gentamicin, tobramycin, neomycin, and streptomycin. Image: Aminoglycoside drug names typically end in “mycin/micin”. Examples include streptomycin and gentamicin.

Penicillin was isolated from other microorganisms, which led to a new term, antibiotics. Using similar discovery and production techniques, researchers discovered many other antibiotics in the 1940s and 1950s: streptomycin, chloramphenicol, erythromycin, vancomycin, and others.12 Apr 2020 ...
