Kingdom Eubacteria
![Page 4: Kingdom eubacteria](https://reader035.fdocuments.net/reader035/viewer/2022062503/58d087801a28ab012d8b5c1f/html5/thumbnails/4.jpg)
Eubateria characteristics1.Cell wall 2.True bacteria 3.Cannot survive in extreme environment
Cell wall are made of
4.Peptidoglycan- is responsible for the rigidity of bacteria
2. Carbohydrate – they only on the extracellular side of cell wall

Basic shape of bacteria
1. Cocci 2.Bacilli3.Spirilla

Cocci- Spherical shape bacterium - Diplococci- pair of cocci- Streptococci- Raws or chain of cocci- Straphyloccoci- grapelike cluster of
cocci

Bacilli- Rod shape
• Streptobacillus also occur in chain

Common disease in human caused by bacteria
![Page 12: Kingdom eubacteria](https://reader035.fdocuments.net/reader035/viewer/2022062503/58d087801a28ab012d8b5c1f/html5/thumbnails/12.jpg)
Propionibacterium acnes- cause pimple and acne
![Page 13: Kingdom eubacteria](https://reader035.fdocuments.net/reader035/viewer/2022062503/58d087801a28ab012d8b5c1f/html5/thumbnails/13.jpg)
Pimple causes1. Almost all teens get acne and pimple
“this is part of teens experience”2. Oily substance called “sebum”

Mycobacterium tuberculosis- Cause TB or tuberculosis
![Page 15: Kingdom eubacteria](https://reader035.fdocuments.net/reader035/viewer/2022062503/58d087801a28ab012d8b5c1f/html5/thumbnails/15.jpg)
Leptospira interrogans- Leptospirosis
![Page 16: Kingdom eubacteria](https://reader035.fdocuments.net/reader035/viewer/2022062503/58d087801a28ab012d8b5c1f/html5/thumbnails/16.jpg)
• This bacteria are present in the urine and tissues of cattle pigs, horses, dogs, rats and wild animals• Larges number of leptospira bacteria are in the urine of rats

Bacillus anthracis- Anthrax“Disease affects animals like cows and carabaos and can be transmitted to humans”

“Year 2000 they use bacillus anthracis to kill people in USA”

Importance of Bacteria
![Page 20: Kingdom eubacteria](https://reader035.fdocuments.net/reader035/viewer/2022062503/58d087801a28ab012d8b5c1f/html5/thumbnails/20.jpg)
Used as antibiotic (Streptomycin) is an antibiotic drug, the first of class of drug, and it was the firsteffective treatment for tuberculosis

E. Coli or Escherichia Coli naturally found in the large intestine of humans. These bacteria meanwhileprovide the much needed vitamin B12

Lactobacillus bulgaricus and Streptobacillus thermophilus Theses are specially involved in making sour milk or Yogurt. Lactase in the bacteria changes the milk sugar into Lactic acid, which gives yogurt its semi-liquid texture.
