Q:

What type of bacteria is rod shaped?

A:

Quick Answer

All bacteria that is rod shaped is considered a bacillus. Bacilli bacteria are distinguished not only by their rod-like appearance, but also by being gram positive. Bacilli are typically aerobic organisms, but there are rare cases of anaerobic bacilli as well.

Full Answer

Bacteria can be harmful or helpful to humans. Some are used in antibiotics to help people when they get sick, while others can cause food poisoning. There are two main types of bacilli: bacillales and lactobacillales. Since bacilli are gram positive cells, they have thick cell walls. When exposed to the Gram stain, they will turn and stay a crystal violet color.

  • Q:

    What are gram negative rods?

    A:

    Gram-negative rods, or bacilli, are rod-shaped bacteria that give a negative result with Gram staining. These bacteria have a thin peptidoglycan layer sandwiched between the inner and outer cell membrane. This layer is removed when the bacterial cells are washed with an alcohol solution so they do not retain the crystal violet stain first applied. Instead, the cells turn red or pink with the safranin or fuchsine counterstain.

    What are biological mutant agents?

    A:

    Biological mutant agents are substances that change the genetic material of organisms, such as DNA, and include certain chemicals and rays, such as ultraviolet radiation, X-rays and gamma rays, along with viruses and bacteria. Many mutagenic agents cause cancer, and are dually classified as carcinogens. While mutant agents cause artificial changes in genetic codes and replication, some mutations occur naturally and are caused by spontaneous hydrolysis and errors in DNA replication, recombination and repair.
