Determining whether Campylobacter species may be the cause of diarrhea
Reflexive testing for Campylobacter species from nucleic acid amplification test-positive feces
This test is generally not useful for patients hospitalized more than 3 days because the yield from specimens from these patients is very low, as is the likelihood of identifying a pathogen that has not been detected previously.
This test provides evidence of the presence of the bacterium, Campylobacter species, in feces in a viable state, and provides an isolate for antibacterial susceptibility testing and, if needed, submission to a health department.
Minnesota healthcare providers are required to report all confirmed or suspected cases of campylobacteriosis to the Minnesota Department of Health. Mayo Clinic Laboratories clients should refer to their local health departments regarding public health submission of Campylobacter isolates.

Fecal
If susceptibility testing is needed, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, Varies. If susceptibility testing is not needed (eg, due to lack of recovery of Campylobacter species from feces), it will not be performed and the ZMMLS order will be canceled at time of report.
In some cases, local public health requirements may impact Mayo Clinic Laboratories clients, requiring, for example, submission of isolates to public health laboratories. Clients should familiarize themselves with local requirements and are responsible for submitting isolates to appropriate public health laboratories. Clients can obtain isolates of Campylobacter species recovered from specimens submitted to Mayo Clinic Laboratories by calling 800-533-1710 as soon as possible after reporting (to ensure viability of the bacterium).
Specimen must arrive within 96 hours of collection.
Specimen source is required.

Diarrhea may be caused by a number of agents, including bacteria, viruses, parasites, and chemicals; these agents may result in similar symptoms. A thorough patient history covering symptoms, severity and duration of illness, age, travel history, food consumption, history of recent antibiotic use, and illnesses in the family or other contacts will help the healthcare provider determine the appropriate testing to be performed.
Campylobacter enteritis is an important cause of acute diarrhea worldwide. The organism inhabits the intestinal tracts of a wide range of animal hosts, notably poultry; contamination from these sources can lead to foodborne disease that is typically caused by Campylobacter jejuni or Campylobacter coli. Campylobacter infection can also be transmitted via water-borne routes or direct contact with animals or animal products. Early symptoms (1-7 days after exposure) include abrupt onset of abdominal pain, diarrhea, and occasionally vomiting. The acute illness is characterized by cramping, abdominal pain, and diarrhea. Patients may report 10 or more bowel movements per day. Bloody feces may be observed. Diarrhea is typically self-limited, lasting around 7 days. Proper hydration is necessary. Antibiotics are not needed for most cases of Campylobacter gastroenteritis, except if patients experience severe disease or if they are immunocompromised.
No growth of Campylobacter species.
The growth of Campylobacter species identifies a potential cause of diarrhea.
The yield of Campylobacter species is reduced when specimens are delayed in transit to the laboratory (>2 hours from collection for unpreserved specimens).
Check local public health requirements, which may require submission of isolates to a public health laboratory.

The fecal specimen is inoculated onto Campylobacter selective agar and grown in microaerophilic conditions at 42 degrees C. After incubation, suspect Campylobacter colonies are identified using one or a combination of the following techniques: Matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry, conventional biochemical tests, carbon source utilization, serologic methods, or nucleic acid sequencing of the 16S ribosomal RNA (rRNA) gene. Campylobacter species that may be reported include but are not limited to: Campylobacter jejuni; Campylobacter coli; Campylobacter fetus; Campylobacter helveticus; Campylobacter hyointestinalis; Campylobacter lari; Campylobacter subantarcticus; and Campylobacter upsaliensis.(Pillai DR, Griener T.
