Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped ...
Auritidibacter ignavus is a Gram-positive, aerobic, non-spore-forming and rod-shaped species of bacteria from the family Micrococcaceae which has been isolated from an ear swab in Bad Orb, Germany. [1] [2] [3] [4]
So far, EAR is the only processive antitermination system specific for Gram-positive bacteria. Further experiments failed to reconstitute EAR-mediated processive antitermination mechanism in vitro or in a Gram-negative heterologous host , suggesting that additional B. subtilis-specific factor(s) may also be required for EAR antitermination.
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species.The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.
Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. [3] Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913). Carl Friedlander described Klebsiella bacillus which is why it was termed Friedlander bacillus for many years.
Neisseria animaloris, formerly named CDC group EF-4a, is a gram-negative coccoid rod. The bacterium is a commensal of the upper respiratory tract of cats and dogs, and they may cause pulmonary infections in cat. [ 1 ]
The previously mentioned protein A, as well as clumping factor, are surface proteins that allow the bacteria to bind to host cells. [20] [7] S. pseudintermedius has been found to produce biofilms, an extracellular matrix of protein, DNA, and polysaccharide, which aids the bacteria in avoiding the host immune system and resisting drugs.

Alcaligenes faecalis is a species of Gram-negative, rod-shaped bacteria commonly found in the environment.It was originally named for its first discovery in feces, but was later found to be common in soil, water, and environments in association with humans.
