Candidatus Helicobacter suis refers to a bacterial species belonging to the Helicobacter genus which infects and colonizes the stomachs of pigs. It is a Gram-negative, spiral-shaped bacterium that exhibits motility utilizing multiple flagella. Candidatus Helicobacter suis is a fastidious microorganism, meaning it has specific growth requirements that make it difficult to culture in the laboratory.
This bacterium is considered an important pathogen in pigs, as it has been associated with various gastric diseases, such as gastritis and gastric ulcers. Infection with Candidatus Helicobacter suis can lead to decreased feed intake, reduced weight gain, and overall poor health in affected animals.
Transmission of Candidatus Helicobacter suis occurs primarily through oral-oral and fecal-oral routes, usually through contaminated food or water. It is believed to be highly prevalent in pork production systems worldwide.
The diagnosis of Candidatus Helicobacter suis infection in pigs typically involves endoscopy and histopathological examination of stomach tissue samples, as well as molecular detection methods such as polymerase chain reaction (PCR).
Treatment options for Candidatus Helicobacter suis infections in pigs are limited, and the development of antibiotic resistance has become a concern. Therefore, prevention and control measures, such as strict hygiene practices and the use of probiotics or vaccines, may be implemented to reduce the transmission and impact of this pathogen on pig health and productivity.
