The antibacterial effects of a combination of Coptidis rhizoma and Galla rhois extracts (CGE) were evaluated in piglets. The minimum bactericidal concentration of CGE was 2.0 mg/mL. Thirty 5-week-old piglets were challenged with Campylobacter (C.) coli after allocation to three different groups, a control and two treatment groups fed with CGE at 2.0 or 4.0 g/kg feed for 7 days. On day 7, C. coli in the feces of the CGE-treated groups were significantly lower than in the control (p < 0.01). These results suggest that CGE can be used to control C. coli in piglets.

1159 diarrhoeal stool specimens were cultured for detecting Campylobacter. Data on epidemiology and clinical symptoms of the disease were also collected. 104 Campylobacter strains were isolated, positive rate 9%. The highest prevalence of the disease was found in 2 age groups: 7-12 months (15%) and 13-24 months (13.1%), and this proportion decreased gradually with increasing age. No seasonal fluctuation was observed. Clinical symptoms of the disease are not typical so the diagnosis should be based on stool examination.

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.

Systemic infections of campylobacter fetus are rare in human beings. Only 22 cases(including our case) of C. fetus infection have been reported in Korea. We are presenting a case of subdural empyema caused by C. fetus. The patient was a 71 year old man of chronic alcoholism.

In August 2021, three students with diarrhea from the same school visited a local hospital in the S district of Beijing. An epidemic investigation showed that there were more students with diarrhea in the same school and they had one meal together. Campylobacter jejuni was isolated from both patients with diarrhea and asymptomatic food handlers; however, the latter also carried Campylobacter coli. Phylogenomic analysis showed that there was a campylobacteriosis outbreak among the students, and the asymptomatic food handler may have been the source of the infection. Routine inspection and surveillance for Campylobacter is needed for the food producing staff, particularly those cooking in the cafeteria in schools or other public food services.

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.

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.
