Whatever brands of antibiotics we buy in the drugstore, we can classify them into five types based on their modes of action or the way they “treat” microbes. This article will discuss on these five modes of action. what modernism was maurice beebe pdf The information and the concepts discussed in this chapter have been organized using three approaches: (1) systematic, (2) experimental, and (3) with examples.

Antibiotic Drugs Metronidazole. Metronidazole is an antiprotozoal, antibacterial and antihelminthic nitroimidazole agent. Chemical structure. The chemical formula is C6H9N3O3 and the molecular weight is 171.2. Mechanism of action. Metronidazole is reduced to disrupt energy metabolism of anaerobes by hindering the replication, transcription and repair process of DNA results in cell death
- Antibiotics have been shown to inhibit one or more of several different functions of inflammatory cells, chemotaxis, the production of reactive oxygen species, and proinflammatory cytokine production. In the context of growth, the latter effect is most important for the following reasons. Upon release of these cytokines, an acute phase response occurs, which has an overall catabolic effect. In
