Campylobacteriosis is a bacterial infection prevalent in puppies younger than six months old. It can cause  disease (usually diarrhoea) in a variety of species including dogs, cats, birds, ferrets, guinea pigs hamsters, rabbits, rodents and other species – including humans. Up to 49 percent of dogs carry campylobacteriosis, shedding it in faeces for other animals to contract.


Can include: fever, vomiting, straining to defecate, loss of appetite, enlarged lymph nodes [also see Canine Intestinal Lymphangiectasia]

Diarrhoea (watery to bloody with mucus and sometimes bile-stained) lasting 5-15 days is usually how the disease presents. Occasionally chronic diarrhoea can result, lasting for months, where there is an increased body temperature and increased white cell count.

Symptoms in humans often present with severe abdominal discomfort, diarrhoea, vomiting, fever.


There are several known causes of the disease, but the most common is from unhygienic kennels which allow animals to come into direct contact with contaminated faeces. Ingestion of contaminated food or water is another mode of transmission. Younger animals are at a greater risk for contracting the disease because of their underdeveloped immune systems.

In dogs the presence of another disease or condition (e.g. pregnancy) may increase susceptibility to the disease.

Humans contract the disease by ingestion or direct contact with infected material (e.g. faeces, or traces of).
