What is the morphology of moraxella catarrhalis?
Moraxella catarrhalis is a Gram-negative aerobic diplococcus that typically appears as pairs of kidney-shaped cells. It does not form spores or capsules, and its cells are non-motile. M. catarrhalis is often found in pairs or short chains when visualized under a microscope.
Does presence of gram negative cocci in sputum gram stain means tuberculosis?
No, the presence of gram-negative cocci in sputum gram stain does not necessarily indicate tuberculosis. Tuberculosis is caused by the bacterium Mycobacterium tuberculosis, which is acid-fast and appears pink on a Ziehl-Neelsen stain. Gram-negative cocci are more commonly associated with other bacterial infections, such as Haemophilus influenzae or Moraxella catarrhalis.
Is moraxella catarrhalis fermentative or oxidative?
Is moraxella catarrhalis fermentative or oxidative?
What is moraxella?
Moraxella are: - bacteria - short gram negative rods that occur in pairs - obligate parasites of mucosal surfaces
How do humans and animals get moraxella bovis?
Moraxella bovis can be transmitted by flies (which transmit the bacteria from the eyes of an infected animal to another) or by direct contact between animals.

What is antibacterial spectrum of macrolides?
Macrolides have a broad-spectrum activity against many bacteria, including gram-positive cocci (such as Streptococcus pneumoniae and Staphylococcus aureus), atypical pathogens (such as Mycoplasma pneumoniae and Legionella pneumophila), and some gram-negative bacteria (such as Haemophilus influenzae and Moraxella catarrhalis).
How do humans and animals get moraxella bovis?
Moraxella bovis can be transmitted by flies (which transmit the bacteria from the eyes of an infected animal to another) or by direct contact between animals.
Gram negative cocci?
Gram positive cocci are bacteria that are spherical in shape and have a thick cell wall made of peptidoglycan. They can be connected in chains, clusters or various other arrangements. They are common on the skin and in the respiratory tract of humans, Some are normal flora, while others are pathogens.
What color is moraxella catarrhalis after the decolorizer is used?
Moraxella catarrhalis is a Gram negative bacterium. Thus, after the decolorizer is used, its thin cell wall won't retain the primary stain. The stain is washed away, and Moraxella catarrhalis is colorless.
Are chlamydia cocci?
Cocci and bacilli do not cause chlamydia. Cocci cause gonorrhea.
What is the scientific name of cocci?
The scientific name for cocci is coccus (plural: cocci). They are a type of spherical-shaped bacteria.
Which one grows in food cocci or bacilli or spirilla?
Cocci
