Campylobacterales

Helicobacter pylori

The Campylobacterales are an order of bacteria. Ecological and as for the metabolism they are a very diverse group. These also include some medically important pathogens. They are provided to the Department of proteobacteria, the Gram stain falls, as with all members of this class, negative.

Features

The cells of the Campylobacterales are usually curved or spirally, except Thiovulum, which is round or ovoid cells. The species are microaerophilic in general, they can only live in environments with low oxygen content. Some are also completely anaerobic, these species can only survive under complete exclusion of oxygen.

Thiovulum is 600 micrometers per second is one of the most rapidly advancing bacteria.

Different types of Campylobacter can cause small bowel inflammation (enteritis ) with bloody diarrhea, called Campylobacter enteritis. Human infection occurs via drinking water and food, often from poultry meat.

There are also some sulfur-oxidizing bacteria within the Campylobacterales available. Thiovulum oxidizing hydrogen sulfide ( H2S) with oxygen ( O2) to elementary sulfur (S). In these reactions, energy is released which is used by the bacteria for the assimilation of carbon dioxide. Thiovulum thus plays an important role in the sulfur cycle of the earth. Which belongs to the family Campylobacteraceae genus Sulfurospirillum reduced elemental sulfur with formic acid or hydrogen and thereby gaining energy. Sulfurospirillum is therefore also important in the sulfur cycle.
