Answer 1

1st discussion about eubacteria

Defination:

Eubacteria, or “true” bacteria, are single-celled prokaryotic microorganisms that have a range of characteristics and are found in various conditions throughout all parts of the world. All types of bacteria fall under this title, except for archaebacteria. Since eubacteria is so common, it comprises one of the three domains of life; the three domains are Archaea, Bacteria, and Eukarya.

Types of eubacteria:

Eubacteria are typically classified into five different phylums: Chlamydias, Cyanobacteria (Blue-green algae), Gram-positive bacteria, Proteobacteria, and Spirochetes. Chlamydias are often parasitic bacteria. Cyanobacteria are most commonly known to be aquatic and obtain energy via photosynthesis.

MAJOR GROUP :

1.Protobacteria

Gram defining :

Gram negative bacteria.

Associated diseases:

gonorrhea and meningitis, members of genus Burkholderia .

Example :

Salmonela.

2. Cyanobacteria :

Gram defining :

Gram negative

Associated diseases :

neurodegenerative diseases such as amyotrophic lateral sclerosis .

Parkinson diseases.

Example:

Nostoc, Oscillatoria, Gloeocapsa.

3. Gram positive bacteria:

Gram defining:

Positive

Associated diseases:

• Anthrax.
• Diphtheria.
• Enterococcal infections.
• Erysipelothricosis.
• Listeriosis.

Example:

• Bacillus. ...
• Clostridium, including Clostridium botulinum, Clostridium tetani, Clostridium difficile, and Clostridium perfringens.
• Corynebacterium, such as Corynebacterium diphtheriae and Corynebacterium jeikeium.
• Listeria, such as Listeria monocytogenes.

4. Chlamydia:

Gram negative bacteria

Associated diseased

trachomatis is the most common infectious cause of blindness and the most common sexually transmitted bacterium.

Example:

Chlamydia trachomatis.

5.

Sphirochetes:

1.Gram negative bacteria

2. Associated diseased:

Relapsing fever

Lyme diseases
