BACKGROUNDThere has been a marked global increase in the incidence of human Campylobacter enteritis in recent years. This study investigated the epidemiological and clinical features of Campylobacter enteritis in adult patients suffering from acute diarrhea.

METHODSThis was a retrospective review of Campylobacter enteritis in adult patients with acute diarrhea presenting at Beijing University First Hospital, Beijing, China, in the summer and autumn (April to October) of 2005 to 2009. The data collected included the species of campylobacter identified, and the age, gender, clinical manifestations and results of laboratory test on stool samples collected from the patients. Campylobacter sensitivity tests to various antimicrobial agents were conducted on 80 specimens. Chi-square tests were applied using SPSS13.0 software and a two-sided P value of < 0.05 was considered statistically significant.

RESULTSCampylobacter spp. isolated from the stool specimens of 142 patients with diarrhea represented 14.9% of all the cases examined. C. jejuni was identified in 127 patients (89.4%) and C. coli in 15 others (10.6%). The infection incidence was highest in the age range of 21 - 30 years which comprised 21.7% of the total cases examined. Most cases of diarrhea (46 patients) occurred in June. Watery diarrhea (97.2%), abdominal pain (72.5%) and fever (64.8%) were the most common manifestations of enteric campylobacteriosis. Only four patients (2.8%) had bloody diarrhea. The antimicrobial resistance rates were: cefoperazone (100%), levofloxacin (61.3%), gentamicin (12.5%), erythromycin (6.3%), and azithromycin (2.5%).

CONCLUSIONSCampylobacter was prevalent among adults with acute diarrhea from 2005 to 2009 in Beijing, China. The large number of those afflicted by the disease warrants the commission of a large multicenter study to determine the extent of enteric campylobacteriosis in this region.

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.

Matteuccia struthiopteris is a nature plant, which contains a lot of potential active components. In the present study, we investigated the effect of polysaccharides extracted from Matteuccia struthiopteris on lupus-like syndrome induced by Campylobacter jejuni CJ-S131 in BALB/c mice. Mice were randomly divided into normal, model control, SLE model (vehicle treated), Matteuccia struthiopteris polysaccharides treated (30 and 15 mg x kg(-1)) groups and prednisone 5 mg x kg(-1) treated groups. The effect of Matteuccia struthiopteris polysaccharides (Ms) on weight and organ index of BALB/c mice was detected. Autoantibodies and total IgG production were measured by enzyme linked immunosorbent assay. Proteinuria was measured and kidneys were examined by light microscopy. Compared with SLE model group, treatment with Matteuccia struthiopteris polysaccharides 30 and 15 mg x kg(-1) reduced weight loss and Matteuccia struthiopteris polysaccharides 15 mg x kg(-1) reduced spleen swelling (P < 0.05). The increased production of autoantibodies and total immunoglobulin G (IgG) were also significantly inhibited. Matteuccia struthiopteris polysaccharides protected kidney against glomerular injury in BALB/c mice with reduced immunoglobulin deposition and lowered proteinuria (P < 0.01). Matteuccia struthiopteris polysaccharides had a protective effect on lupus-like syndrome induced by CJ-S131 in BALB/c mice.
