Campylobacter fetus may cause infections such as septicemia, peritonitis, meningitis, endocarditis, septic arthritis, and cellulitis, increasing the risk of spontaneous abortion but decreasing the likelihood of gastroenteritis. We identified C. fetus from continuous ambulatory peritoneal dialysis (CAPD) fluid using 16S rRNA gene sequencing. It is significant that this is the first case report in Korea of CAPD peritonitis caused by C. fetus, which is known to be rare.

The purpose of this case report was to report a rare case of pyogenic spondylodiscitis caused by Campylobacter fetus. A 37-year-old male presented with fever and low back pain. By lumbar magnetic resonance imaging (MRI), no abnormal finding was observed at the first presentation. However, low back pain was aggravated, and fever did not improve. Thus, lumbar MRI was repeated on the 26 day after the onset of symptoms, showing abnormal signals at vertebrae and disc spaces, and pyogenic spondylitis was diagnosed. The possibility of pyogenic spondylodiscitis should be taken into account if a patient presents with low back pain and fever, and areas of low signal intensity on a T1-weighted MRI should be carefully examined. When initial MRI does not reveal abnormal findings, repeated MRI after one or two weeks or, more favorably, immediate gadolinium enhancement MRI, are important for patients who have persistent low back pain and fever.

Campylobacter (C.) fetus (epsilonproteobacteria) is an important veterinary pathogen. This species is currently divided into C. fetus subspecies (subsp.) fetus (Cff) and C. fetus subsp. venerealis (Cfv). Cfv is the causative agent of bovine genital Campylobacteriosis, an infectious disease that leads to severe reproductive problems in cattle worldwide. Cff is a more general pathogen that causes reproductive problems mainly in sheep although cattle can also be affected. Here we describe a multiplex PCR method to detect C. fetus and differentiate between subspecies in a single step. The assay was standardized using cultured strains and successfully used to analyze the abomasal liquid of aborted bovine fetuses without any pre-enrichment step. Results of our assay were completely consistent with those of traditional bacteriological diagnostic methods. Furthermore, the multiplex PCR technique we developed may be easily adopted by any molecular diagnostic laboratory as a complementary tool for detecting C. fetus subspecies and obtaining epidemiological information about abortion events in cattle.

Campylobacter jejuni is one of the important bacterial pathogens causing entero-invasive diarrhea; however, C. jejuni infection is rarely complicated by bacteremia or extra-intestinal localization. In the domestic literature, the majority of the relevant reports have focused on Campylobacter fetus, which causes bacteremia more frequently than enteritis, but there are no reports of C. jejuni bacteremia in Korea. We present the case of a 13-year-old girl who presented with abdominal pain. Blood cultures revealed curved Gram- negative bacilli and small, mucoid, gray colonies on blood agar plates at 37degrees C. Biochemical tests showed oxidase-positive colonies. To confirm the species, 16S rRNA sequence analysis was performed. The isolate exhibited 99.7% homology to C. jejuni subsp. jejuni. The patient was treated with third-generation cephalosporin and aminoglycoside and had negative blood cultures after three days of treatment. She fully recovered within four days with no complications.

Two trials of external quality assessment for clinical microbiology laboratory were performed in 2005. A total of 12 specimens were distributed. Six specimens were distributed to 308 laboratories with 272 (88.3%) returns in Trial I and 276 (89.6%) returns in Trial II. The acceptable percentages of Gram-stain were relatively good. The acceptable percentages of bacterial identification on Acinetobacter baumannii, Staphylococcus aureus, Streptococcus pyogenes, Aeromonas hydrophila, Enterococcus casseliflavus, Brucella species (Trial I) were 80.1%, 98.3%, 87.6%, 81.3%, 55.5%, 38.1%, respectively. The acceptable percentages of bacterial identification on Klebsiella pneumoniae, Enterococcus faecalis, Brahamella catarrhalis, Burkholderia cepacia, Campylobacter fetus, Rhodoccus equi (Trial II) were 97.5%, 85.9%, 71.0%, 85.9%, 8.3%, 51.0%, respectively. The acceptable percentages for antimicrobial susceptibility tests on Acinetobacter baumannii, Staphylococcus aureus and Klebsiella pneumoniae were relatively high, but those on Klebsiella pneumoniae for ESBL and Enterococcus faecalis for vancomycin-resistance were not high. In conclusion, the acceptable percentages of bacterial stain and identification were relatively good except C. fetus. However, it is necessary that the quality assurance of the individual laboratories should be improved for antimicrobial susceptibility tests, and the selection of the most appropriate antimicrobial agents to test should be also considered.

Campylobacter fetus is a rare cause of endocarditis. To date, only about 30 cases of C. fetus endocarditis have been reported mainly in the elderly with chronic underlying illnesses. Most cases showed tendency to involve aortic valve. This report describes a case of native tricuspid valve infective endocarditis in a 69-year-old man without any underlying disease. Despite adequate antibiotic therapy for 4-weeks, endocarditis recurred and leading to surgical valve replacement.

Campylobacter f etus has been increasingly associated with extraintestinal infections in patients with underlying diseases. Pulmonary involvement in human by this organism is rare. We report a case of septic pneumonia secondary to community-acquired C. f etus bacteremia in a 67 year-old man with chronic renal failure.

The authors report a case of Campylobacter fetus subsp. fetus gastro-intestinal infection and bacteremia with poly-arthritis, mainly of the hip, in a French patient simultaneously suffering from cirrhosis of the liver. The outcome was eventually favorable, however only after a trial of ineffective pefloxacin-gentamicin therapy. The authors suggest: (i) gentamicin should not be given alone in C. fetus subsp. fetus infections, and (ii) pefloxacin should not be given if antibiotic sensitivities data are not available. The inconclusive reliability of disk diffusion tests for C. fetus subsp. fetus should be recognized.
