Beside this, how do you know if its bactericidal or bacteriostatic?
The formal definition of a bactericidal antibiotic is one for which the ratio of MBC to MIC is ≤ 4, while a bacteriostatic agent has an MBC to MIC ratio of > 4.
is ciprofloxacin bacteriostatic or bactericidal? For instance, ciprofloxacin, a fluoroquinolone, exhibits a bacteriostatic activity when the replication of DNA is inhibited by inhibiting DNA gyrase and a bactericidal activity caused by bacterial DNA fragmentation.
Likewise, are quinolones bactericidal or bacteriostatic?
Quinolones are chemotherapeutic bactericidal drugs, eradicating bacteria by interfering with DNA replication. Quinolones inhibit the bacterial DNA gyrase or the topoisomerase IV enzyme, thereby inhibiting DNA replication and transcription. Topoisomerase II is also a target for a variety of quinolone-based drugs.
Is streptomycin bacteriostatic or bactericidal?
Streptomycin is an aminoglycoside antibiotic produced by the soil actinomycete Streptomyces griseus. It acts by binding to the 30S ribosomal subunit of susceptible organisms and disrupting the initiation and elongation steps in protein synthesis. It is bactericidal due to effects that are not fully understood.
