Reliable transport of Campylobacter jejuni isolates is critical to microbial epidemiology research, especially in developing countries without a good temperature control mailing system. Various factors, including oxygen, temperature, transport medium composition, could affect the survival of C. jejuni. In this study, the protective effects of different ingredients in C. jejuni transport media at 4 °C and 25 °C and under aerobic condition were quantitatively evaluated respectively. The results showed that enriched medium, supplementation with 5% blood and being kept at 4 °C could improve the viability of different C. jejuni strains during transport. In addition, supplementation with 25 mmol/L L-fucose in Wang's transport medium could significantly improve the survival of C. jejuni at both 4 °C and 25 °C. To the best of our knowledge, this is the first report to evaluate the protective effect of L-fucose in enriched C. jejuni transport medium which is feasible in developing countries without an effective cold chain mailing system. These data will be good reference for C. jejuni transport medium improvement in future.

The present study evaluated the effects of a mixture of Galla rhois and Cinnamomum cassia extracts (GCE) (1 : 1, w/w) on susceptibility to the colonization of Campylobacter (C.) jejuni in broilers. Eighty two-week-old broilers (n = 20 per group) were used to estimate the efficacy of GCE against C. jejuni infection via drinking water. Antibacterial activity testing revealed that the minimum bactericidal concentration of GCE against C. jejuni was 2.5 mg/mL. Broilers challenged with C. jejuni were administered 0.0 (Non-GCE), 2.5 (GCE-2.5), 5.0 (GCE-5.0) and 10.0 g/L (GCE-10) GCE for 7 days, and the cecal contents were collected from five broilers per group on the 1st, 3rd, 5th, and 7th day post-treatment. On day 3 post-administration, the number of C. jejuni in GCE-5.0 (p < 0.05) and GCE-10 (p < 0.01) was significantly decreased relative to Non-GCE, while on day 7 those in all GCE-treated groups were significantly decreased compared to the Non-GCE group (p < 0.001). Hematological and blood biochemical analysis revealed no significant differences in parameters between the Non-GCE and GCE-treated groups. Based on the results of the present study, GCE was identified as a safe and alternative candidate to suppress C. jejuni colonization in broilers.

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.

Guillain-Barre Syndrome (GBS) has been known to be preceded by various infections such as Campylobacter jejuni, cytomegalovirus, and so on. We have experienced a case of GBS after a preceding herpes zoster, which was complicated by GBS, which is rare. Some circumstantial and experimental clues suggest a possible causal relationship between those two. Here we report the case along with a literature review.

OBJECTIVE:
Campylobacter jejuni NCTC11168 is commonly used as a standard strain for flagellar biosynthesis research. In this report, two distinguished phenotypic isolates (CJ1Z, flhA mutant strain, lawn; CJ2S, flhA complemented strain, normal colony) appeared during laboratory passages for NCTC11168.
METHODS:
Phenotypic assessments, including motility plates, transmission electron microscopy, biofilm formation assay, autoagglutination assay, and genome re-sequencing for these two isolates (CJ1Z, flhA mutant strain; CJ2S, flhA complemented strain) were carried out in this study.
RESULTS:
Transmission electron microscopy revealed that the flagellum was lost in CJ1Z. Phenotypic assessments and genome sequencing of the two isolates were performed in this study. The capacity for biofilm formation, colony auto-agglutination, and isolate motility was reduced in the mutant CJ1Z. Comparative genomic analysis indicated a unique native nucleotide insertion in flhA (nt, 2154) that caused the I719Y and I720Y mutations and early truncation in flhA.
CONCLUSION
FlhA has been found to influence the expression of flagella in C. jejuni. To the best of our knowledge, this is the first study to describe the function of the C-terminal of this protein.

BACKGROUND: The test for hippurate hydrolysis is critical for differentiation of C. jejuni and other thermophilic Campylobacter species. So, we evaluated the disk method for detection of hippurate hydrolysis by C. jejuni. METHODS: Twenty-eight Campylobacter species isolated from stool culture were simultaneously tested with disk method for detection of hippurate hydrolysis and polymerase chain reaction (PCR) for hippuricase specific gene. Disk method was tested with difference in incubation time (2 hours vs. 4 hours), hippurate concentration (1%, 2%, and 4%), amount of ninhydrin (50 microliter vs. 100 microliter), and inoculation method (colony vs. suspension of organism adjusted by turbidity), finally, 24 types of disk methods were performed. RESULTS: By using hippuricase PCR method as the reference for the detection of hippurate hydrolysis, the disk method showed a sensitivity of 91.7% and a specificity of 100% when two kinds of disk methods were simultaneously performed. CONCLUSIONS: The disk method for detection of hippurate hydrolysis is simple to use and require fewer cells than the tube method do, and should be useful as a routine diagnostic test in clinical laboratory for rapid identification of C. jejuni.

Campylobacter jejuni was isolated from the blood of a 31-year-old woman who suffered a mid-trimester septic abortion with fever and headache. Histologically, evidence of septic abortion was found, with an intervillous abscess and acute villitis. Complete clinical recovery followed termination of the pregnancy and the use of antibiotics. C. jejuni is an unusual cause of septic abortion in humans. To our knowledge, no case has been reported in Korea.

Guillain-Barre syndrom(GBS) is not a single entity, but may arise from a variety of pathogenic mechanisms. In GBS, abnormally increased autoantibody levels to GM, constitute a group with motor neuropathy predominantly and substantial axonal damage, particularly those following Campylobacter enteritis. We report a patient, 43 years old male, who presented with 3 days history of rapidly progressive weakness of all extremities. Electreophysiologic studies were suggestive of axonal form of motor dominant polyneuropathy, Using ELISA, autoantibody of MAG(myelin associated glycoprtein) and SGPG(sulfoglucuronyl paraglobiside) showed normal ranges, but IgG GM. Autoantibodies abnormally elevated. Additionally antibody titer of Campylobacter jejuni increased. We reported the axonal form of Guillain, Barr syndrome associated with IgG GM,, Ab and antiCampylobacter jejuni antibody.

Campylobacter infection causes gastrointestinal symptoms such as abdominal pain or diarrhea. Occasionally, Campylobacter bacteremia affects immunocompromised patients; however, serious outcomes are known to be rare. Here, we present a case of a patient with Campylobacter bacteremia who had underlying liver cirrhosis. The patient had fever and diarrhea. These symptoms subsided after treatment with cefotaxime. Campylobacter jejuni was isolated in the blood culture after 10 days. In addition, previously reported cases of Campylobacter bacteremia in Asian countries were reviewed with respect to antimicrobial sensitivities.
