    Electron is a negatively charged particle having an absolute charge of - 1.6 x 10-19 coulombs. Since this is the smallest negative charge carried by a particle, so this is taken as the unit of negative charge, and we say that the relative charge of an electron is - 1. The charge of an electron is equal in magnitude but opposite in sign to the charge of a proton. A normal atom has an equal number of protons and electrons and since a proton and an electron have equal and opposite charge, an atom on the whole is electrically neutral. Electron is the lightest of the three atomic particles.

    Trypanosoma is a genus of kinetoplastids, a monophyletic group of unicellular parasitic flagellate protozoa. The name is derived from the Greek trypano- and soma because of their corkscrew-like motion. Most trypanosomes are heteroxenous and most are transmitted via a vector.

    It is difficult to make antiviral medicines than making antibodies because viruses have few biochemical machanisms of their own they enter host cells and use their machinery for their life process. So antiviral medicines will work against the host body. Antibiotics block bacterial synthesis pathways without affecting the body because the bacteria use its own metabolic pathway machinery so, it will not affect the hist body.
