Clinical Effects

Epidemiology

Habitat

  • Found in animals and their products:
    • Milk.
    • Poultry.
    • Feces.

Lifecycle

  • Multiplies in the intestinal tract of the host, and invades epithelial cells.
  • Transfers R. plasmids, which most commmonly carry tetracycline-resistant genes.

Transmission

  • Feco-oral route Disease transmission.
  • Sexual transmission of C. fetus subsp. venerealis.
  • C. Jejuni infection is an important zoonosis.
    • Human beings and other susceptible species obtain infection from animal sources.
    • Infection of human beings occurs following ingestion of an animal product originally contaminated with infected feces.
    • Most human infections occur following consumption of poorly cooked meat and unpasteurized milk.
    • Handling of animals (especially dogs and cats) may also be a source of human infection.
    • Important zoonosis.
    • Causes the following in humans:
      • Diarrhea.
      • Abdominal pain.
      • Fever.
      • Sometimes vomiting

Pathological effects

  • Circulating antibodies develop during enteritis, but may not be protective.
  • Local antibody immune response results in clearance of uterine infections.
  • Sheep and goats are immune following abortion.
  • Produce an adhesion → adhere to cells of intestinal or reproductive tract.
  • Toxin production varies with Campylobacter species.
  • Diseases:
    • Enteritis in many species.
    • Abortion in sheep and cattle Abortion & Stillbirths.
    • Bovine genital campylobaceriosis.
    • Mastitis.
    • Hepatitis in poultry.

Other Host Effects

  • Normal intestinal flora in many species, especially poultry, cattle, pigs, dogs and cats.
  • Reproductive tract species:
    • C. fetus subsp. venerealisis carried in preputial crypts and vagina, especially cattle.
    • C. fetus subsp. fetus carried in intestinal tract of carrier sheep and cattle.
  • C. jejuni frequently causes abortion in sheep and occasionally cattle.

Control

Control via animal

  • Meticulous hygiene and cleaning to prevent spread.
  • Avoid the use of carrier bulls.

Control via chemotherapies

Control via environment

  • Control in veterinary hospitals is carried out by strict adherence to hygiene procedures including:
    • Hand-washing.
    • Cleaning and disinfection of equipment.
    • Human infections may be prevented by hygienic practices and thorough cooking of food.

Vaccination

  • Vaccines do exist for problem herds.
