Bacteria
Bacteria belong to the kingdom Prokaryotae. Their cells are smaller than our cells, but
they can reproduce rapidly. In the right conditions, some types of bacteria can
reproduce every 20 minutes or so. Once in the human body, they multiply rapidly.
Their presence can cause disease by damaging cells or by releasing waste products
1
that are toxic to us. Bacteria cause diseases such as Cholera and Tuberculosis.…read more

assist in healing.
Ringworm is caused when the fungi attaches and grows on
keratin-containing cells, such as those found in the skin, near the hair
and fingernails.

introduced into other plants when those come in contact with this sap. Sucking
insects such as aphids do not spread TMV. The virus particles are found in all parts of
the plant except the few cells at the tips of the growing points. Infected stock plants
should be discarded immediately. TMV can also survive outside the plant in sap that
has dried on tools and other surfaces.…read more

lead to death. While there is no cure for HIV, medications are available that interferes
with virus replication, which in turn helps preserve the health and function of the
immune system. A healthy immune system is able to fight off those opportunistic
infections and AIDS defining illnesses.
HIV medications can't rid the body entirely of HIV. HIV medications are not a cure.…read more

Malaria is an infection caused by single-celled parasites that enter the blood
through the bite of an Anopheles mosquito. These parasites, called plasmodia, belong
to at least five species. Most human infections are caused by either Plasmodium
falciparum or Plasmodium vivax. Plasmodium parasites spend several parts of their
life cycle inside humans and another part inside mosquitoes.…read more
