Bacteria
They are formed by a single rudimentary cell. They have no nucleus or plastids, but chromatin. Some have assimilators pigments. They are on earth, water, and air, and can generally move.
They may be causing disease and therefore are called pathogens. Those that do not cause disease are called saprophytes. In some cases, they are even useful, as in digestive processes or synthesis of vitamins.
By the way, they are called coconuts when circular; bacilli if they have the form of rods; spirals if its shape is spiral. Their shapes vary according to the environment.
If they need oxygen to live they are called aerobic and if they don’t need it anaerobic; if they are involved in a capsule they are called capsulated.

Envelope: In some cases a cell membrane of the host is utilized for encasement of the virus; this may be either the external cell membrane or the nuclear membrane.
Infectious mononucleosis
Infectious mononucleosis, or mono, refers to a group of symptoms usually caused by the Epstein-Barr virus (EBV). It typically occurs in teenagers, but you can get it at any age. The virus is spread through saliva, which is why some people call it “the kissing disease.”
People with mono often have a high fever, swollen lymph glands, and a sore throat. Most cases of mono are mild and resolve easily with minimal treatment. The infection is typically not serious and usually goes away on its own in one to two months.
The incubation period of the virus is the time between when you contract the infection and when you start to have symptoms. It lasts four to six weeks. The signs and symptoms of mono typically last for one to two months.
The symptoms may include:
• A fever.
• A sore throat.
• Swollen lymph glands in the neck and armpits.
• A headache.
