The correct spelling of the bacterial species "spirillum metchnikovi" is pronounced as /spɪˈrɪləm ˌmɛtʃnɪˈkoʊvi/. The first part of the word "spirillum" is pronounced as /spɪˈrɪləm/ with stress on the second syllable. The second word "metchnikovi" is pronounced as /ˌmɛtʃnɪˈkoʊvi/ with stress on the third syllable. This bacterium was named in honor of Sergei Sergeievich Metchnikoff, a Nobel laureate who contributed significantly to the field of immunology. Spirillum metchnikovi is rod-shaped and can be found in various environments such as soil and water.
Spirillum metchnikovi is a species of bacteria that belongs to the genus Spirillum. It was named after the Russian bacteriologist Sergey Metchnikov, who first discovered and described it in the late 19th century.
Spirillum metchnikovi is a Gram-negative, spiral-shaped bacterium that typically measures around 3 to 5 micrometers in length. It has a characteristic helical or corkscrew appearance and is often found in freshwater environments such as lakes and ponds.
This bacterium is considered to be a microaerophile, meaning it requires a low level of oxygen to survive. It is also motile and possesses several flagella, which enable it to move in a corkscrew-like pattern.
S. metchnikovi is known to be pathogenic, meaning it can cause diseases in certain animals, including fish and amphibians. In these hosts, it can cause symptoms such as skin ulcers, internal infections, and overall deterioration of health.
Additionally, Spirillum metchnikovi has been used in scientific research as a model organism for studying topics like bacterial chemotaxis, the process by which bacteria move towards or away from different chemical substances in their environment.
Overall, Spirillum metchnikovi is a peculiar and potentially harmful bacterium that possesses distinctive helical morphology and holds significance in the fields of microbiology and pathology.

The word "spirillum" originates from the Latin word "spīra" meaning "coil" or "spiral". It refers to the shape of the bacteria that appear as spirals or coils.
The term "metchnikovi" is derived from the name of the Russian biologist Ilya Ilyich Mechnikov (also spelled Metchnikov) who made significant contributions to the field of microbiology, particularly in the study of immunology and bacteriology. Mechnikov is known for his research on phagocytosis, the immune response, and the establishment of the concept of innate immunity. The bacterial species "spirillum metchnikovi" is named after him in recognition of his contributions to the field.
