Q:

What harm do spirilla bacteria cause?

A:

Quick Answer

Spirilla bacteria are Gram-negative bacteria that may cause bacterial diarrhea, adenocarcinoma and peptic ulcers.These bacteria are one of several varieties of bacteria that cause illness or disease in humans; mycoplasmas, chlamydiae, spirochetes and mycobacteria are other virulent and potentially destructive organisms. Spirilla bacteria are identified by their unique body shapes, which resemble spiral pasta noodles, and the type of physical harm that they cause to humans.

Full Answer

Spirilla bacteria belong to the larger class of Gram-negative bacteria: this group, along with Gram-positive, contains all bacteria living on the Earth. These bacteria have distinct helical or spiral-shaped bodies, and digest food using respiratory metabolism. Spirilla have rigid cell walls, which distinguishes them from spirochetes, and use polar flagella to move. These bacteria are responsible for creating two human pathogens: bacterial diarrhea and peptic ulcers. There is also evidence, according to Textbook of Biology, that spirilla bacteria may be linked to the development of cancerous cells called adenocarcinoma. Bacterial diarrhea is typically caused by the consumption of contaminated food, such as undercooked shellfish and poultry, and to a lesser extent, contaminated drinking water. Helicobacter, a type of spirilla, is attributed to the generation of peptic ulcers in humans; this bacteria irritates stomach lining, and enables the colonization of gastric mucosal cells.
