Campylobacterales is an order of bacteria within the class Epsilonproteobacteria. This order includes several genera that are significant in both medical microbiology and veterinary microbiology. Members of this order are typically Gram-negative, microaerophilic, and spiral-shaped.

Taxonomy

The order Campylobacterales is divided into several families, including:

• Campylobacteraceae
• Helicobacteraceae

Genera

Some of the notable genera within the Campylobacterales order include:

• Campylobacter
• Helicobacter
• Arcobacter

Characteristics

Members of the Campylobacterales order are known for their unique spiral shape and their ability to thrive in low-oxygen environments. They are often found in the gastrointestinal tract of animals and humans. These bacteria are microaerophilic, meaning they require oxygen levels lower than that of the atmosphere to grow.

Pathogenicity

Several species within the Campylobacterales order are known to cause diseases in humans and animals. For example:

• Campylobacter jejuni is a leading cause of gastroenteritis worldwide.
• Helicobacter pylori is associated with peptic ulcers and gastric cancer.

Ecology

Campylobacterales are commonly found in the gastrointestinal tract of birds and mammals. They can also be found in various environmental sources such as water and soil. These bacteria play a role in the microbiome of their hosts and can be involved in both commensalism and pathogenesis.

Research and Clinical Importance

Research on Campylobacterales has significant implications for public health and veterinary medicine. Understanding the pathogenesis and epidemiology of these bacteria can help in developing better diagnostic, preventive, and therapeutic strategies.
