What does bacillus mean in bacteria?

What does bacillus mean in bacteria?

Bacillus, (genus Bacillus), any of a genus of rod-shaped, gram-positive, aerobic or (under some conditions) anaerobic bacteria widely found in soil and water. The term bacillus has been applied in a general sense to all cylindrical or rodlike bacteria. Bacillus frequently occur in chains.

What kingdom does Bacillus anthracis belong to?

Data Quality Indicators:

What disease is caused by Bacillus bacteria?

Anthrax is a serious infectious disease caused by gram-positive, rod-shaped bacteria known as Bacillus anthracis. Anthrax can be found naturally in soil and commonly affects domestic and wild animals around the world.

What is the common name of Bacillus anthracis?

Other names for this organisms include Bacteridium anthracis and Bacillus cereus var. anthracis. Common names include “anthrax” and “anthrax bacterium” (16).

What is the Colour of Bacillus?

Bacillus subtilis is a typical germ, which is rod-shaped and Gram-positive. When cultured on ordinary nutrient agar, the morphology circular colony of this bacteria is rough, opaque, fuzzy white or slightly yellow with jagged edges [1, 7].

What are the names of the two bacterial kingdoms?

These are the bacteria (or eubacteria ) and the archaebacteria (or the Archaea ). The members of these two kingdoms appear similar in shape and appearance, even under the extreme magnification of the electron microscope .

What shape are the bacteria classified as Bacillus subtilis?

Bacillus subtilis, known also as the hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants and humans. A member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions.

What are the members of the genus bacilli?

Members of the genus Bacillus are large, aerobic, gram-positive, and sporeforming rods. They are catalase positive; many are fermentative and most are motile. Bacillus species occur widely in nature, being found in the air, water, and soil.

What kind of environment does a bacilli bacteria live in?

Bacillus spp. bacteria show a wide range of characteristics that allow them to live in most natural environments ( Griffiths, 2010 ). Bacillus comprises a large group of ubiquitous Gram-positive, rod-shaped, aerobic-to-facultatively anaerobic, endospore-forming saprophytes ( Weber and Rutala, 1988 ).

These are the bacteria (or eubacteria ) and the archaebacteria (or the Archaea ). The members of these two kingdoms appear similar in shape and appearance, even under the extreme magnification of the electron microscope .

What do you need to know about bacterial classification?

Cover different classification schemes for grouping bacteria, especially the use of the Gram stain 2. Describe the different types of bacteria 3. Discuss bacterial structure and the function of the different bacterial components 4. Discuss the distinguishing characteristics of Gram positive and Gram negative bacteria.

How are the different types of Bacillus bacteria different?

Bacillus species are rod-shaped, endospore-forming aerobic or facultatively anaerobic, Gram-positive bacteria; in some species cultures may turn Gram-negative with age. The many species of the genus exhibit a wide range of physiologic abilities that allow them to live in every natural environment. Only one endospore is formed per cell.

Where do members of the genus Bacillus live?

Genus – Bacillus: Members of the genus bacilicus inhabit soil, can be found in water, and posses peritrichous flagella for movement. More about peritrichous flagella can be read about in adaptations. ( Anthrax)
