FIVE TYPES OF BACTERIA – In this topic, we are going to learn and identify the following five types of bacteria, its meaning and examples.
According to MedicalNewsToday, bacteria (singular: bacterium) are microscopic, single-celled organisms that exist in their millions, in every environment, both inside and outside other organisms.
There are those that are harmful but most of these have a useful purpose. Bacteria support many forms of life, may it be plant or animal, and these are used in industrial and medicinal processes.
There are five types: coccus, bacillus, spirillum, rickettsia, and mycoplasma.
- Coccus | Cocci
- These bacteria are spherical in shape. Examples include:
- Staph aureus
- S. hominis
- S. saphrophyticus
- Strep pyrogenes (gr. A)
- E. faecalis
- S. sanguis group
- S. angiosus group
- A. adiacens
- N. gonorrhea
- Moraxella catarrhalis
- These bacteria are spherical in shape. Examples include:
- Bacillus | Bacilli
- Basically, these are rod-shaped, there are those bacilli that are curved known as vibrio. Examples include:
- C. diptheriae
- C. urealyticum
- Lactobacillus sp.
- Erisipelothrix rhusiopathiae
- Escherichia coli
- Proteus spp.
- C. koseri
- Enterobacter cloacae
- Vibrio cholera
- Aeromonas hydrophila
- Stenotrophomonas maltophilia
- Basically, these are rod-shaped, there are those bacilli that are curved known as vibrio. Examples include:
- Spirillum| Spirrila
- These bacteria are spiral in shape. Tight-coiled spirilla are known as spirochetes. Examples include:
- Treponema carateum
- Borrelia burgdorferi
- Borrelia afzelii
- Leptospira interrogans
- Spirillum minus
- Chlamydophila pneumoniae
- Bacteroides fragilis
- Capnocytophaga canimorsus
- Prevotella intermedia
- Fusobacterium nucleatum
- These bacteria are spiral in shape. Tight-coiled spirilla are known as spirochetes. Examples include:
- Rickettsia
- These bacteria behave like viruses and cannot live outside living cells. Examples include:
- Rickettsia rickettsii
- Rickettsia akari
- Rickettsia conorii
- Rickettsia sibirica
- Rickettsia australis
- Rickettsia felis
- Rickettsia japonica
- Rickettsia africae
- Rickettsia hoogstraalii
- Rickettsia prowazekii
- These bacteria behave like viruses and cannot live outside living cells. Examples include:
- Mycoplasma
- These type do not have a cell wall and can be either cocci or bacilli. Examples include:
- M. buccale
- M. fermentans
- M. gallisepticum
- M. hominis
- M. hyopneumoniae
- M. hyorhinis
- M. lipophilum
- M. penetrans
- M. pirum
- M. salivarium
- These type do not have a cell wall and can be either cocci or bacilli. Examples include:
