Bacteria cells. They are the smallest living thing on Earth (known to man).
The largest amoeba is more than 2,500 times larger than the smallest bacterium.
The giant amoeba is 5000 times larger than the smallest bacterium. This is calculated by dividing the size of the giant amoeba (1000 micrometers) by the size of the smallest bacterium (0.2 micrometers).
If your are asking about the virus which feeds on bacteria then it is BACTERIOPHAGE

Measles is caused by a virus called the measles virus, specifically the measles morbillivirus. It is a highly contagious virus that spreads through respiratory droplets from an infected person.
Virus
Ribosomes are the smallest between mitochondria, viruses, bacterium, and protein. Ribosomes are the building blocks of mitochondria, viruses, bacterium, and proteins.
Smallest Prion-virus-bacterium-protozoan-helminth Largest
Clostridium tetani is a bacterium.
A yeast cell is the biggest followed by the bacteruim then the virus The virus is easily the smallest it can be up to 1/10000th of the size of a bacterium! A bacteria is about 1.8 millionth of a meter a yeast cell is about a 12 millionth of a meter which means the yeast cell is more than 6x larger than a bacterium!
AIDS is not caused by bacterium. It is caused by a virus called HIV (human immunodeficiency virus)
A virus is much much much smaller then a bacterium. Virus called phage can infect bacteria.
Live pathogens
No- its a virus.
No. HIV is a virus.
