Abstract
Oral Campylobacter species are rarely reported to cause extraoral infections. Here we present three cases of extraoral abscess caused by an oral Campylobacter sp. and a Streptococcus sp. The Campylobacter species were all isolated anaerobically and identified by sequencing analysis of the 16S rRNA gene. The cases included a breast abscess caused by Campylobacter rectus and a non-group A beta-hemolytic streptococcus in a patient with lymphoma, a liver abscess caused by Campylobacter curvus and an alpha-hemolytic streptococcus in a patient with complicated ovarian cancer, and a postobstructive bronchial abscess caused by C. curvus and group C beta-hemolytic Streptococcus constellatus in a patient with lung cancer. The abscesses were drained or resected, and the patients were treated with antibiotics with full resolution of the lesions. The C. curvus cases are likely the first reported infections by this organism, and the C. rectus case represents the second such reported extraoral infection.

Abstract
The world-wide increase of antimicrobial resistance in micro-organisms complicates medical treatment of infected humans. We did a risk-factor analysis for the prevalence of antimicrobial resistant Campylobacter coli on 64 Swiss pig finishing farms. Between May and November 2001, 20 faecal samples per farm were collected from the floor of pens holding finishing pigs shortly before slaughter. Samples were pooled and cultured for Campylobacter species. Isolated Campylobacter strains were tested for resistance against selected antimicrobials. Additionally, information on herd health and management aspects was available from another study. Because data quality on the history of antimicrobial use on the farms was poor, only non-antimicrobial risk factors could be analysed. Statistical analyses were performed for resistance against ciprofloxacin, erythromycin, streptomycin, tetracycline, and for multiple resistance, which was defined as resistance to three or more antimicrobials. Risk factors for these outcomes--corrected for dependency of samples at herd level--were analysed in five generalised estimation-equation models. Prevalence of antimicrobial resistance among Campylobacter isolates was ciprofloxacin 26.1%, erythromycin 19.2%, streptomycin 78.0%, tetracycline 9.4%, and multiple resistance 6.5%. Important risk factors contributing to the prevalence of resistant strains were shortened tails, lameness, skin lesions, feed without whey, and ad libitum feeding. Multiple resistance was more likely in farms which only partially used an all-in-all-out system (OR = 37), or a continuous-flow system (OR = 3) compared to a strict all-in-all-out animal-flow. Presence of lameness (OR = 25), ill-thrift (OR = 15), and scratches at the shoulder (OR = 5) in the herd also increased the odds for multiple resistance. This study showed that on finishing farms which maintained a good herd health status and optimal farm management, the prevalence of antimicrobial resistance was also more favourable.

Abstract
Campylobacter jejuni is the most common cause of community-acquired acute bacterial diarrhea. Campylobacter diarrhea is usually accompanied by fever and abdominal pain. Campylobacter diarrhea is usually watery. Nausea, vomiting, headache, and myalgias may also be present. Tenesmus is a common feature. The majority of patients with Campylobacter diarrhea have some component of segmental colitis, usually beginning in the small bowel and progressing distally to the cecum and colon. C. jejuni is a rare cause of pancolitis. Community-acquired colitis may be caused by C. jejuni or other enteric pathogens, for example, Shigella, Entamoeba, Yersinia, Escherichia coli 0157:H7, Clostridium difficile colitis, ischemic colitis, or idiopathic ulcerative colitis. We present a case of C. jejuni pancolitis in an elderly woman. Differential diagnosis is included in the discussion. The patient's C. jejuni pancolitis was successfully treated with a 7-day course of oral moxifloxacin.

Abstract
Five commercial broiler flocks were treated with a fluoroquinolone for a clinically relevant infection. Fresh feces from individual chickens and environmental samples were cultured for campylobacters before, during, and weekly posttreatment until slaughter. Both Campylobacter jejuni and C. coli were isolated during all treatment phases. An increased proportion of quinolone-resistant strains was seen during treatment, and these strains persisted posttreatment. One quinolone-resistant isolate of each species, each serotype, and each phage type from each sample at all treatment phases was examined for its phenotype and mechanism of resistance. Two resistant phenotypes were isolated: Nal(r) Cip(r) and Nal(r) Cip(s). The majority (269 of 290) of fluoroquinolone-resistant isolates, whether they were C. jejuni or C. coli, had a mutation in gyrA that resulted in the substitution Thr-86-->Ile. The other gyrA mutations detected were Thr-86-->Ala (n = 17) and Asp-90-->Asn (n = 10). The genotypic variation, based on the silent mutations in gyrA identified by the denaturing high-performance liquid chromatography pattern and DNA sequencing, was used to supplement typing data and provided evidence for both the spread of preexisting resistant strains and the selection of spontaneous resistant mutants in treated flocks. Multidrug resistance was significantly (P < 0.01) associated with resistance to ciprofloxacin. Twenty-five percent (73 of 290) of ciprofloxacin-resistant isolates but only 13% (24 of 179) of susceptible isolates were resistant to three or more unrelated antimicrobial agents. In conclusion, quinolone-resistant campylobacters were isolated from commercial chicken flocks in high numbers following therapy with a veterinary fluoroquinolone. Most ciprofloxacin-resistant isolates had the GyrA substitution Thr-86-->Ile. Resistant isolates were isolated from the feces of some flocks up to the point of slaughter, which may have consequences for public health.

Abstract
Campylobacter species are known as agents of enteritis worldwide. However, rural community-based studies on Campylobacter infections are lacking. We carried out a prospective case-control study from July to December 2002 to investigate the prevalence and socio-epidemiological determinants of Campylobacter infection in a rural community in north India and the drug resistance of Campylobacter strains isolated from the community. Stool specimens from 348 subjects with diarrhoea and 351 age- and gender-matched asymptomatic controls were cultured for Campylobacter, Salmonella and Shigella. All Campylobacter strains were identified and tested for antibiotic susceptibility. Campylobacter species were isolated from 47 (13.5%) subjects with diarrhoea and 2 (0.6%) asymptomatic controls respectively (P<0.001). Campylobacter infection was significantly higher in children aged less than 5 years, families engaged in agriculture and persons who did not wash their hands with soap after peri-anal washing following defaecation. Campylobacter infections were more frequent than combined Salmonella and Shigella infections (47/348 vs. 15/351; P<0.001) in subjects with diarrhoea. Only two Campylobacter-infected individuals with diarrhoea had bloody stools. Antibiotic resistance of Campylobacter species was as follows: ampicillin 81.6%, ciprofloxacin 71.4%, tetracycline 26.5%, furazolidine 14.3%, gentamicin 10.2% and erythromycin 6.1%; 30.6% of strains were multidrug resistant. Increased quinolone resistance and multidrug resistance pose major risks for treatment failure.

Abstract
Five commercial broiler chicken flocks were treated with either difloxacin or enrofloxacin for a clinically relevant infection, as instructed by a veterinarian. Campylobacters were isolated from individual fecal samples and from samples associated with the broiler environment before, during, and after treatment. Ciprofloxacin-resistant Campylobacter jejuni and/or C. coli strains were detected pretreatment in four flocks, but they constituted a very small proportion of the campylobacters present. When the broilers were treated with a fluoroquinolone, a rapid increase in the proportion of ciprofloxacin-resistant campylobacters was observed. During treatment nearly 100% of campylobacters were resistant, and in some flocks a high proportion of resistant strains persisted for up to 4 weeks after treatment. Prior to treatment a variety of campylobacter subtypes were present. During and after treatment considerable changes in both species and subtype prevalence were observed, but no single fluoroquinolone-resistant clone became dominant. Instead, resistant C. coli strains or a mixture of resistant C. coli and C. jejuni strains became dominant, whereas susceptible C. jejuni strains had usually been dominant prior to treatment. The resistant subtypes which emerged and became dominant were not always the same as those detected pretreatment. The persistence of resistant strains for up to 4 weeks posttreatment has important implications for any strategy designed to avoid the introduction of such strains into the food chain.

Abstract
Salmonella and Campylobacter infections occur commonly in children. Some of these infections are severe, requiring treatment with antimicrobial agents. Many classes of antimicrobial agents that are used in humans also are used in food animals for growth promotion, disease prevention, and therapy. The use of such antimicrobial agents in food animals increases the likelihood that human bacterial pathogens that have food animal reservoirs, such as Salmonella or Campylobacter, will develop cross-resistance to drugs approved for use in human medicine. Resistance determinants also may be transmitted from food animals to humans through the food supply with bacteria that usually are commensal, such as Escherichia coli and enterococci. Clinicians should be aware that antimicrobial resistance is increasing in food-borne pathogens and that patients who are taking antimicrobial agents for any reason are at increased risk for acquiring antimicrobial-resistant food-borne infections. Several European countries have demonstrated that restricting the use of antimicrobial agents in food animals can be followed by a decrease in antimicrobial resistance in humans without compromising animal health or significantly increasing the cost of production. Appropriate use of antimicrobial agents in humans and food animals is an important factor in maintaining their effectiveness.

Abstract
Campylobacter jejuni, a major foodborne human pathogen, has become increasingly resistant to fluoroquinolone (FQ) antimicrobials. By using clonally related isolates and genetically defined mutants, we determined the fitness of FQ-resistant Campylobacter in chicken (a natural host and a major reservoir for C. jejuni) in the absence of antibiotic selection pressure. When monoinoculated into the host, FQ-resistant and FQ-susceptible Campylobacter displayed similar levels of colonization and persistence in the absence of FQ antimicrobials. The prolonged colonization in chickens did not result in loss of the FQ resistance and the resistance-conferring point mutation (C257 --> T) in the gyrA gene. Strikingly, when coinoculated into chickens, the FQ-resistant Campylobacter isolates outcompeted the majority of the FQ-susceptible strains, indicating that the resistant Campylobacter was biologically fit in the chicken host. The fitness advantage was not due to compensatory mutations in the genes targeted by FQ and was linked directly to the single point mutation in gyrA, which confers on Campylobacter a high-level resistance to FQ antimicrobials. In certain genetic backgrounds, the same point mutation entailed a biological cost on Campylobacter, as evidenced by its inability to compete with the FQ-susceptible Campylobacter. These findings provide a previously undescribed demonstration of the profound effect of a resistance-conferring point mutation in gyrA on the fitness of a major foodborne pathogen in its natural host and suggest that the rapid emergence of FQ-resistant Campylobacter on a worldwide scale may be attributable partly to the enhanced fitness of the FQ-resistant isolates.

Abstract
We investigated the serotypes, distributions, and antimicrobial resistance of Campylobacter jejuni isolates from humans and animals as a source of infection in poultry between 2002 and 2003. A total of 50 C. jejuni isolates from humans and 29 C. jejuni isolates from poultry were studied for serotype using the Penner serotyping scheme and the drug susceptibilities of the isolates which were determined for 7 antimicrobial drugs using the disk diffusion method. Serotype B (10%), serotype E (8%) and serotype R (8%) were found in humans isolates, while serotype A (27%) was most freguently isolated from poultry, followed by serotype K (21%) and serotype C (13%). Resistance in human isolates to cephalothin was high (100%). Resistance to trimethoprim/sulfamethoxazole, ciprofloxacin, and nalidixic acid were observed in 90, 82 and 78% of isolates, respectively. Most of the isolates (88%) were susceptible to erythromycin. High levels of resistance to drugs (ciprofloxacin and nalidixic acid) were observed in the isolates from poultry. These results indicate the importance of poultry as a reservoir of C. jejuni infection in Thailand is limited. In addition, a high proportion of the isolates were resistant to antimicrobial drugs, particularly the quinolone group.

Abstract
Infection in humans with Campylobacter jejuni is commonly associated with exposure to food animal fecal material. In this study, we report on the recovery, potential for virulence and antimicrobial resistance levels of C. jejuni isolated from food and companion animals. Three hundred and seventy-eight fecal samples from food and companion animals and surface swabs from beef carcasses were tested for the presence of C. jejuni. C. jejuni was isolated from 13.8% (11/80) of dogs, 5% (1/20) of goats, 28.3% (17/60) of dairy cattle, 0% (0/65) of range cattle, 73.5% (36/49) of feedlot cattle, and 94.7% (18/19) of beef carcasses. Beef cattle from a single Arizona herd showed a considerable increase in fecal shedding of C. jejuni from pasture to feedlot and over time on the feedlot. Forty-two isolates were tested for susceptibility to four antimicrobial agents, each representing a class of antimicrobial drug approved for use in both humans and animals. None of the isolates were found to be resistant to erythromycin or gentamicin, whereas 2.4% of isolates were resistant to ciprofloxacin and 28.6% of isolates were resistant to tetracycline. The presence of virulence traits among the 42 isolates was assessed using in vitro macrophage survival and epithelial cell adherence and invasion assays. Of the isolates examined, 17 were able to survive within macrophages through 72 h at viable counts of >/=10(3)/well and 12 were capable of invading epithelial cells at viable counts of >/=10(3)/well. Data from these studies suggests that many of the isolates recovered from the non-poultry animal sources have the capacity to cause disease if transmitted to humans.

Abstract
Infection with Campylobacter species is a predominant cause of food-borne gastroenteritis in the industrialized world. Bacteremia is detected in <1% of patients with diarrhea, mainly in immunocompromised hosts or those in the extremes of age. Reported here is the case of a 78-year-old, immunocompromised male patient with Campylobacter jejuni subsp. jejuni bacteremia complicated by cellulitis. The infection was characterized by a protracted course with several recurrences and refractoriness to multiple antibiotic regimens, responding only to a prolonged course of meropenem treatment. The frequency of cellulitis as reflected in previously reported series of Campylobacter bacteremia and the clinical characteristics of this difficult-to-treat infection are reviewed.

Abstract
Reported here is the successful management of a severe case of Campylobacter fetus subspecies fetus meningitis, complicated by septic shock, in a patient without overt immunosuppression who was cured by imipenem. Meningitis caused by C. fetus has rarely been reported in adults, and only exceptionally in non-immunocompromised patients, and septic shock has not previously been reported as a complication of such meningitis. The best antibiotic regimen for treating this condition remains to be determined. Imipenem has displayed high in vitro activity against C. fetus but has been used rarely in clinical practice. It was administered in this case with good results.

Abstract
We integrated data on quinolone and macrolide susceptibility patterns with epidemiologic and typing data from Campylobacter jejuni and C. coli infections in two Danish counties. The mean duration of illness was longer for 86 patients with quinolone-resistant C. jejuni infections (median 13.2 days) than for 381 patients with quinolone-sensitive C. jejuni infections (median 10.3 days, p = 0.001). Foreign travel, eating fresh poultry other than chicken and turkey, and swimming were associated with increased risk for quinolone-resistant C. jejuni infection. Eating fresh chicken (of presumably Danish origin) was associated with a decreased risk. Typing data showed an association between strains from retail food products and broiler chickens and quinolone-sensitive domestically acquired C. jejuni infections. An association between treatment with a fluoroquinolone before stool-specimen collection and having a quinolone-resistant C. jejuni infection was not observed.

Abstract
We summarize antimicrobial resistance surveillance data in human and chicken isolates of Campylobacter. Isolates were from a sentinel county study from 1989 through 1990 and from nine state health departments participating in National Antimicrobial Resistance Monitoring System for enteric bacteria (NARMS) from 1997 through 2001. None of the 297 C. jejuni or C. coli isolates tested from 1989 through 1990 was ciprofloxacin-resistant. From 1997 through 2001, a total of 1,553 human Campylobacter isolates were characterized: 1,471 (95%) were C. jejuni, 63 (4%) were C. coli, and 19 (1%) were other Campylobacter species. The prevalence of ciprofloxacin-resistant Campylobacter was 13% (28 of 217) in 1997 and 19% (75 of 384) in 2001; erythromycin resistance was 2% (4 of 217) in 1997 and 2% (8 of 384) in 2001. Ciprofloxacin-resistant Campylobacter was isolated from 10% of 180 chicken products purchased from grocery stores in three states in 1999. Ciprofloxacin resistance has emerged among Campylobacter since 1990 and has increased in prevalence since 1997.

Abstract
The aim of the study was to assess Campylobacter infections in 309 patients with acute enterocolitis, 272 patients with relapses of chronic enterocolitis, 70 patients with inflammatory bowel disease (involving Crohn's disease and ulcerative colitis) and 31 patients with other chronic intestinal illnesses. Isolation and identification were performed conventionally. Limited agar dilution method was used for susceptibility testing of the strains. Campylobacter species were isolated in patients with acute enterocolitis (7.8%), chronic enterocolitis (6.2%), Crohn's disease (6.2%), ulcerative colitis (3.7%), and irritable bowel syndrome (8.3%). Hippurate-positive Campylobacter jejuni isolates accounted for 62.2% of Campylobacter strains. One tetracycline resistant Campylobacter upsaliensis isolate was detected from a girl with acute enterocolitis. Resistance rates to erythromycin (31.1%) and clarithromycin (22.2%) were high, whereas those to amoxicillin/clavulanate (4.4%), ampicillin/sulbactam (13.3%), tetracycline (24.4%) and ciprofloxacin (22.2%) were relatively low. Resistance to erythromycin and either tetracycline or ciprofloxacin was detected in 8.9% and 6.7%. The involvement of Campylobacter infection in relapses of chronic intestinal disorders and the susceptibility patterns of the strains strongly emphasize the role of Campylobacter as a cause of infection in this group of patients.

Abstract
A 33-year-old woman underwent a liver transplantation and splenectomy in 1985 and had followed immunosuppressive therapy until 1995. Afterwards a non-Hodgkin lymphoma was diagnosed and chemotherapy was started. In January 2000, because of suspect transplantation rejection she was treated with steroid and immunosuppressive therapy. Fever occurred after two months and Cytomegalovirus (CMV) infection was diagnosed. Ganciclovir was started with clinical remission. In November 2000 fever recurred without clinical symptoms. Lymphoma recurrence was excluded and CMV was detected by PCR in several biological fluids. Blood cultures were positive for a bacterium that was identified as Campylobacter fetus. The patient was successfully treated with intravenous ciprofloxacin. For persistent CMV viremia therapy with gancyclovir was stopped and foscarnet was used (60mg/Kg/tid i.v. for two weeks). Bacteremia due to C. fetus is rare, occurring mainly in immunocompromised patients. In our patient the immunosuppressive therapy, chemotherapy for lymphoma and CMV infection had made the patient susceptible to bacteremia with this infrequently found bacterium. The clinical microbiologist should be aware of this infection in immunocompromised hosts.

Abstract
Thermophilic Campylobacter species, including Campylobacter jejuni and Campylobacter coli, are responsible for foodborne campylobacteriosis in humans and are increasingly resistant to fluoroquinolone (FQ) antimicrobials. The therapeutic use of FQ antimicrobial agents in food animal production, particularly in poultry, has become a concern for public health, because the practice may promote the emergence of FQ-resistant Campylobacter that can be transmitted to humans through the food chain. Recent studies have indicated that Campylobacter displays a hypermutable phenotype in response to in vivo treatment with FQ antimicrobials, resulting in the rapid emergence of resistant mutants. Distinct from other Gram-negative bacteria, the acquisition of FQ resistance in Campylobacter does not require stepwise accumulation of gyrA mutations and overexpression of efflux pumps, and is mainly mediated by single-step point mutations in gyrA in the presence of a constitutively expressed multidrug efflux pump, CmeABC. The simplicity of the resistance mechanisms may facilitate the rapid adaptation of Campylobacter to FQ treatment. The FQ-resistant Campylobacter mutants derived from chickens do not show a fitness cost in vivo and are ecologically competitive in the colonization of chickens even in the absence of antimicrobial selection pressure. These findings suggest that FQ-resistant Campylobacter may continue to persist regardless of antimicrobial usage, and highlight the need for extra effort to prevent the occurrence and spread of FQ-resistant Campylobacter in animal reservoirs.

Abstract
Campylobacter coli rarely causes bacteremia or extraintestinal infection. We report herein a case of agammaglobulinemia in which cellulitis associated with C. coli bacteremia relapsed after a disease-free interval of >5 years. Pulsed field gel electrophoresis revealed that the organisms in this patient were genetically identical, suggesting a latent C. coli infection.
