Eubacteria: Many Cause Disease

What they are - biological definition

The eubacteria are part of one of the Monera Kingdom groups (the other group is Archaea). These bacteria are prokaryote organisms and represent the largest number of species within the Monera Kingdom. The Eubacteria Group includes all bacteria (excluding archaebacteria) and cyanobacteria.

Summary of key bacterial characteristics:

- Shapes vary by species and can be spiral, spherical or cylindrical.

- Most species obtain food through the absorption process.

- Reproduction of eubacteria occurs by bipartition (asexual form).

- Many are pathogenic (causing disease in humans and animals).

- Some species produce endospores, which are resistance structures. These endospores remain in the environment until they infect a person.


- Perform photosynthesis.

- They have chlorophyll.

- They have a structure similar to that of bacteria (one of the main reasons for being part of the Eubacteria Group).

- Reproduction of cyanobacteria is also asexual and bipartite.

Examples of pathogenic eubacteria:

- Vibrio cholerae - cholera-causing bacteria.

- Clostridium botulinum - bacterium that causes botulism.

- Bordetella pertussis - pertussis-causing bacteria.

- Mycobacterium leprae - leprosy-causing bacteria.

- Treponema pallidum - bacteria causing syphilis.
