The correct way(s) to write the name of a bacterium in the binomial system is/are

Options

A. Coli
B. coli Escherichia
C. Escherichia coli
D. E. coli

Answer

To write the name of a bacterium in the binomial system correctly, follow these steps:

1. **Understand the Binomial Nomenclature**: The binomial nomenclature system consists of two parts: the genus name and the species name. This system is used to uniquely identify organisms.

2. **Capitalize the Genus Name**: The first part of the name is the genus, which should always start with a capital letter. For example, in *Escherichia coli*, "Escherichia" is the genus name.

3. **Lowercase the Species Name**: The second part of the name is the species, which should always start with a lowercase letter. In the example *Escherichia coli*, "coli" is the species name.

4. **Italicize the Entire Name**: When writing the name of the bacterium, the entire binomial name should be italicized. For example, it should be written as *Escherichia coli*.

5. **Use of Abbreviations**: If the genus name is mentioned again in the same text, it can be abbreviated to its first letter (capitalized), followed by a period. For example, after introducing *Escherichia coli*, you can refer to it as *E. coli* in subsequent mentions.

**Final Answer**: The correct way to write the name of a bacterium in the binomial system is to write the genus name first (capitalized), followed by the species name (lowercase), and italicized, e.g., *Escherichia coli*.
