The cetacean microbiome is the group of communities of microorganisms that reside within whales.. Microbiomes play an important role in individual health and ecology and in particular in the discovery of different microbiomes in gut, skin and nose permitted to analyze their conditions and the condition of the Microbiome environment in which they live.
B. ceti has been found via PCR isolation in 4 out of 14 cetacean families but antibodies against the bacteria have been isolated in 7 families. [1] Within these families, B ceti has been cultured or found in Sowerby's beaked whales (Mesoploden bidens), longfinned pilot whales (Globicephala melas), [4] northern minke whales (Balaenoptera acutorostrata), Cuvier's beaked whale (Ziphius ...
Cetacean bodies are generally similar to those of fish, which can be attributed to their lifestyle and the habitat conditions. Their body is well-adapted to their habitat, although they share essential characteristics with other higher mammals . [14] They have a streamlined shape, and their forelimbs are flippers.

Cetacea (/ s ɪ ˈ t eɪ ʃ ə /; from Latin cetus 'whale', from Ancient Greek κῆτος 'huge fish, sea monster') is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises.
The following is a list of currently existing (or, in the jargon of taxonomy) 'extant' species of the infraorder cetacea (for extinct cetacean species, see the list of extinct cetaceans). The list is organized taxonomically into parvorders, superfamilies when applicable, families, subfamilies when applicable, genus, and then species.
The Gram stain, developed in 1884 by Hans Christian Gram, characterises bacteria based on the structural characteristics of their cell walls. [ 174 ] [ 75 ] The thick layers of peptidoglycan in the "Gram-positive" cell wall stain purple, while the thin "Gram-negative" cell wall appears pink. [ 174 ]
Francisella is a genus of Gram-negative bacteria. They are small coccobacillary or rod-shaped , non motile organisms, which are also facultative intracellular parasites of macrophages . [ 1 ] Strict aerobes , Francisella colonies bear a morphological resemblance to those of the genus Brucella . [ 2 ]
