Difference between Antibiotics and Antibacterial

Antimicrobials are reactants that mostly work across a variety of organism such as parasites, protozoa, helminthes, malware and fungus. Medications (Antibiotics), on the other hand are part of a sub type of that large group and include chemicals that have the ability to stop and destroy the development of parasites. Medical students and pharmacists are required to learn the differences between antimicrobials and antibiotics for a better understanding. If you are looking to find the dissimilarities between these two terms, you should consider reading the relevant literature. Some of the main differences between Antibacterials and antibiotics are also explained below.

    As described already, the antimicrobials or antibacterial act against a variety of micro organisms. There are some antimicrobials that act across several micro organisms such as metranidazol, which prevents obligate anaerobic parasites in addition to protozoa and fungus. To be a perfect anti-microbial medication, it should intervene with the vital features of infection, without impacting the characteristics of the hosting  molecules.

    Antimicrobial agents are generally categorised as anti-bacterial, anti-fungal, antiviral and anti protozoa depending on the organism they react with. This type of medication act together with the natural level of resistance of the body and act on different sites in the focus on the target such as molecules’ centre and edges, cytoplasmic tissue layer, synthesis of proteins and nucleic acidity metabolic rate.

    Antibiotics on the other hand are reactants that destroy and prevent the development of small or micro organisms in patient’s body. They act by disrupting the cell walls synthesis; suppressing proteins features and by interfering with the nucleic acidity metabolic rate.

    Antibiotics are generally categorised as bacteriostatic, which works mainly by suppressing microbe multiplication and bactericidal, which works mainly by eliminating the parasites. But this is being used less frequently in the current medical applications since most bacteriostatic medications were shown to be bactericidal at high levels.

    Before starting the anti-biotic therapy, it should be based on the likely micro organisms involved, occurrence of the level of resistance of the affected types of micro organisms, appropriate pharmacology and existence of allergic reaction with a variety of factors that can affect the pharmacology, the level of the intensity, emergency and the accessibility to the environment and understanding of results. To be a perfect anti-biotic, it should be less expensive, easily available with the ability to cure the disease, available in the oral gel or oral cream forms, the less harmful and have less negative reactions. This type of medication is generally used to overcome severe operative infections and as part of surgical processes.

    Consider reading relevant books and journals for detailed information on the topic.
