It makes bacteria the ultimate r-selected organism. They are small, thus requiring few nutrients, thus having a short life span and a fast rate at which they reproduce, so that an individual bacteria is incredibly weak, has low resistance, but a given species as a whole is incredibly strong, able to bounce back quickly from a cataclysm, has high resiliency.
An obligate aerobe bacterium requires oxygen for its metabolism and survival.
The largest bacterium is Thiomargarita namibiensis, which can have a size of up to 0.75 mm in diameter and up to several millimeters in length.
The average size of a bacterium is typically around 1-10 micrometers in diameter. However, some bacteria can be as small as 0.2 micrometers or as large as 750 micrometers.
The largest bacterium is Thiomargarita namibiensis, which can reach up to 0.75mm in length, making it one of the largest known bacteria.
Bacterium size is measured by a technique called Micrometry. With micrometry you can measured the size of very small beings like bacteria, cells, etc. This technique involves the use of a microscope in which the eye piece is calibrated in micrometers. A similarly calibrated slide is used for standardization. The specimen is then mounted and the size measured. Normally, the size of many cells are taken into account and an average value is taken, since all cells may not be of the same size.

Themoose's large size makes survival in warm climates difficult,
The largest bacterium is Thiomargarita namibiensis, which can have a size of up to 0.75 mm in diameter and up to several millimeters in length.
A virus is much much much smaller then a bacterium. Virus called phage can infect bacteria.
Bacteria are all unicelular, but some live in colonies where they actually don't differ that much in cell size. 'Bacteria' is the plural form of 'bacterium'.
All bacterium is microscopic.
50-500 nm
0.2 to 5 microns
The polysaccharide capsule provides a protective layer around the bacterium, enhancing its ability to evade the host's immune system by inhibiting phagocytosis. This capsule can also help the bacterium retain moisture, contributing to its survival in harsh environments. Additionally, it may facilitate adherence to surfaces or host tissues, promoting colonization and infection. Overall, the capsule significantly increases the bacterium's pathogenic potential.
