Some additional coccobacilli bacteria include Gram-negative Yersinia pestis, responsible for the devastating “Black Plague” of the 14th century; Gram-negative Bordetella pertussis is responsible for “whooping cough”, which observed mostly in children with a characteristic “whoop” sound while inhaling; and Gram negative …

What bacteria is Gram positive coccobacilli?

What does coccobacilli look like?

Coccobacilli are a type of bacteria that are shaped like very short rods or ovals. The name “coccobacilli” is a combination of the words “cocci” and “bacilli.” Cocci are sphere-shaped bacteria, while bacilli are rod-shaped bacteria. Bacteria that fall between these two shapes are called coccobacilli.

Which organism is coccobacilli?

A coccobacillus (plural coccobacilli) is a type of rod-shaped bacteria. The word coccobacillus reflects an intermediate shape between coccus (spherical) and bacillus (elongated). Coccobacilli rods are so short and wide that they resemble cocci. Haemophilus influenzae and Chlamydia trachomatis are coccobacilli.

Which is the Gram negative species of coccobacilli?

What’s the difference between a cocci and a bacilli?

Gram Negative Coccobacilli. A coccobacillus is a type of bacterium with a shape intermediate between cocci and bacilli i.e., they are very short rods which may be mistaken for cocci. These small, pleomorphic gram-negative bacteria range in shape from round (cocci) to short, thin rods (bacilli); hence the bacteria are called “coccobacilli.”.

What are the medical effects of Gram negative cocci?

Gram Negative Cocci. M. catarrhalis can cause pneumonia, especially in patients with alcoholism or chronic obstructive lung disease. M. catarrhalis also causes exacerbations of chronic obstructive pulmonary disease (COPD) and chronic bronchitis in elderly patients.

How are Gram positive and Gram negative bacteria divided?

Bacteria are traditionally divided into the two groups: gram-positive and gram-negative, based on their gram-staining response. Gram-positive bacteria are also referred to as monoderms having one membrane, and gram-negative bacteria are also referred to as diderms, having two membranes.
