What is E. coli bacteria PDF?

Escherichia coli (also known as E. coli) is a Gram-negative, facultative anaerobic, rod-shaped bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).

What are the four types of E. coli?

coli infections are typically classified into five categories:

  • Enterotoxigenic (ETEC)
  • Enteropathogenic (EPEC)
  • Enteroinvasive (EIEC)
  • Enterohemorrhagic (EHEC)
  • Enteroaggregative (EAEC)

What is the characteristics of E. coli?

CHARACTERISTICS: Enteropathogenic Escherichia coli (EPEC) are in the family Enterobacteriaceae 2. The bacteria are gram negative, rod shaped, non-spore forming, motile with peritrichous flagella or nonmotile, and grow on MacConkey agar (colonies are 2 to 3 mm in diameter and red or colorless) 5.

How many types of E. coli are there?

More than 700 serotypes of E. coli have been identified. Most varieties of E. coli are harmless or cause relatively brief diarrhea, but a few strains can cause severe abdominal cramps, bloody diarrhea and vomiting.

What are the 5 classification of microorganisms?

The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below.

What are the 7 levels of classification for bacteria?

In bacterial taxonomy, the most commonly used ranks or levels in their ascending order are: species, genera, families, orders, classes, phyla, and domain (Table 3.1). Species is the basic taxonomic group in bacterial taxonomy.

What are the characteristics of E. coli?

What is the structure of E. coli?

E. coli is Gram-negative and its envelope has three layers: cytoplasmic membrane, peptidoglycan, and outer membrane. The peptidoglycan is rigid determining the rod shape.

What is E. coli common name?

Escherichia coli (/ˌɛʃəˈrɪkiə ˈkoʊlaɪ/), also known as E. coli (/ˌiː ˈkoʊlaɪ/), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms.

What is the structure and function of E. coli?

Escherichia coli cells are surrounded by a complex cell wall composed of two concentric lipid bilayers, the outer membrane and the cytoplasmic membrane with a peri- plasmic space in between. This cell wall plays many functional roles in protection, transport, locomotion, sensing, detoxification, and energy production.

What are the classification system?

Definition. Classification systems are ways of grouping and organizing data so that they may be compared with other data. The type of classification system used will depend on what the data are intended to measure. Some datasets may use multiple classification systems.

What are the 4 classification of bacteria?

Bacteria can be classified based on their shape into bacillus, coccus, vibrio and spirillum.

What are the 5 criteria for classification of bacteria and give examples?

Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

What are two structures of E. coli?

In E. coli, there are two distinct membranes: the OM and the inner membrane (IM) (Fig. 1) [4, 5]. And the envelope defines cell shape and allows the cell to sustain large mechanical loads such as turgor pressure [6].

What are the 5 types of classification?

They are: (i) Geographical classification, (ii) Chronological classification, (iii) Qualitative classification, and (iv) Quantitative classification.

What are the 3 types of classification?

The three types of classification are artificial classification, natural classification and phylogenetic classification.

What is the 3 classification of bacteria?

Bacteria are usually grouped into three categories, classified by shape: spherical, cylindrical and spiral.

What are the methods of classification?

There are two methods of classification: i) classification according to attributes, and ii) classification according to variables. An attribute is a qualitative characteristic which cannot be expressed numerically. Only the presence or absence of an attribute can be known. For example.

What is classification and its types?

A classification is a division or category in a system which divides things into groups or types. Its tariffs cater for four basic classifications of customer. [ + of] 2. See also classify.

What are the 4 types of classification?

Broadly speaking, there are four types of classification. They are: (i) Geographical classification, (ii) Chronological classification, (iii) Qualitative classification, and (iv) Quantitative classification.
