Besides Yersinia pestis (see plague) the Yersinia group of bacteria also includes two species frequently causing illness (mainly enteritis) in humans; Yersinia enterocolitica and Yersinia pseudotuberculosis.
Listeriosis is a disease caused by Listeria monocytogenes. The disease primarily causes problems in pregnant women, newborns, and adults with a weakened immune system.
Enteric infections due to Salmonella bacteria are generally referred to by the term ‘salmonellosis’ when they are due to Salmonella species other than Salmonella typhi and Salmonella paratyphi.
Botulism is a serious paralytic illness caused by a nerve toxin produced by the bacterium Clostridium botulinum. The disease may occur after eating foods containing the toxin or due to development of the spores within the intestine of young children or within wounds.
Campylobacteriosis is a diarrhoeal disease caused by Campylobacter bacteria, found in animals such as poultry, cattle, pigs, wild birds and wild mammals
Cholera is an acute diarrhoeal infection caused by the bacterium Vibrio cholera of serogroups O1 or O139. Humans are the only relevant reservoir, even though Vibrios can survive for a long time in coastal waters contaminated by human excreta.
Cryptosporidia are intestinal parasites infecting a variety of animals (e.g. cattle, sheep, rodents, cats and dogs, but also birds, fish and reptiles). Human infections occur due to Cryptosporidium parvum, a species that also affects domestic animals.
