What is the definition of antiviral agents?
Antiviral agents are medicines that treat viral infections. Antivirals like oseltamivir phosphate (Tamiflu), peramivir (Rapivab), or zanamivir (Relenza) can be used to treat the flu or to help prevent it…
Definition of Antibacterial

Control of Microorganisms
Control of microorganisms is essential in order to prevent the transmission of diseases and infection, stop decomposition and spoilage, and prevent unwanted microbial contamination. Microorganisms are controlled by means of…
Bacterial Growth Curves using a Spectrophotometer
Bacteria are as interesting as they are diverse. Though tiny, these unicellular life forms make huge contributions to many systems and cycles. From helping break down food in your intestine;…
Types of culture media used in microbiology
Media are of different types on consistency and chemical composition. A. On Consistency: 1. Solid Media. Advantages of solid media: (a) Bacteria may be identified by studying the colony character,…
Eukaryotic Microorganisms
The domain Eukarya contains all eukaryotes, including uni- or multicellular eukaryotes such as protists, fungi, plants, and animals. The major defining characteristic of eukaryotes is that their cells contain a…
Types of Microorganisms
Most microbes are unicellular and small enough that they require artificial magnification to be seen. However, there are some unicellular microbes that are visible to the naked eye, and some…
VIRUSES
Viruses are the smallest of all the microbes. They are said to be so small that 500 million rhinoviruses (which cause the common cold) could fit on to the head…
How do bacteria reproduce?
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium…
