Campylobacter fetus
Campylobacter fetus is a species of Gram-negative bacteria within the genus Campylobacter. It is known to cause infections in both humans and animals, particularly in cattle and sheep. This bacterium is of significant concern in the fields of veterinary medicine and infectious disease.
Characteristics[edit | edit source]
Campylobacter fetus is a curved, rod-shaped bacterium that is motile due to the presence of a single polar flagellum. It is microaerophilic, requiring reduced levels of oxygen for growth. The bacterium is oxidase-positive and catalase-positive, which are important diagnostic features.
Pathogenesis[edit | edit source]
In humans, Campylobacter fetus can cause bacteremia, gastroenteritis, and meningitis, particularly in immunocompromised individuals. In animals, it is a major cause of bovine genital campylobacteriosis, leading to infertility and abortion in cattle. The bacterium can also cause ovine abortion in sheep.
Transmission[edit | edit source]
The primary mode of transmission in animals is through direct contact with infected tissues or fluids, particularly during mating or through contaminated water and feed. In humans, infection can occur through the consumption of contaminated food or water, or through direct contact with infected animals.
Diagnosis[edit | edit source]
Diagnosis of Campylobacter fetus infection is typically made through culture of the bacterium from clinical specimens, such as blood, stool, or tissue samples. Molecular methods, such as polymerase chain reaction (PCR), can also be used for detection and identification.
Treatment[edit | edit source]
Treatment of Campylobacter fetus infections generally involves the use of antibiotics, with erythromycin and ciprofloxacin being commonly used. In animals, management practices to prevent infection include good hygiene, proper handling of reproductive tissues, and vaccination.
Prevention[edit | edit source]
Preventive measures in livestock include maintaining good farm hygiene, using artificial insemination to reduce the risk of transmission, and implementing vaccination programs. In humans, prevention focuses on proper food handling, cooking meat thoroughly, and avoiding consumption of unpasteurized dairy products.
