Campylobacter is a genus of bacteria that are commonly found in the intestines of animals, including poultry, cattle, and swine. They can also be found in water, soil, and food products. Campylobacter species are a leading cause of foodborne illness worldwide, with symptoms ranging from mild diarrhea to more severe complications such as Guillain-Barré syndrome. Research in the field of Campylobacter typically focuses on understanding the biology and genetics of these bacteria, as well as developing effective methods for prevention, detection, and control of Campylobacter infections. This includes studying the epidemiology of Campylobacter contamination in food and water sources, identifying risk factors for transmission to humans, and investigating potential treatments or vaccines to combat Campylobacter infections.
