Abstract
Non-fermenting Gram-negative bacilli, such as Sphingomonas paucimobilis (S.paucimobilis), are among the most widespread causes of nosocomial infections. Up to now, no definitive guidelines exist for antimicrobial therapy for S. paucimobilis infections. As we have shown that some dietary fibers exhibit pronounced immune-regulatory properties, we hypothesized that specific immune active dietary fibers might modulate the responses against S. paucimobilis. We studied the immunomodulatory effects of dietary fibers against S. paucimobilis on cytokine release and maturation of human dendritic cells (DCs) in co-cultures of DCs and intestinal epithelial cells (IECs). S. paucimobilis infection resulted in increased release of pro-inflammatory cytokines and chemokines by DCs/IECs; these effects were strongly attenuated by specific dietary fibers. Chicory inulin, sugar beet pectin, and both starches had the strongest regulatory effects. IL-12 and TNF-α were drastically diminished upon exposure to chicory inulin and sugar beet pectin, or both starches. High-maize 260, was more effective in the reduction of chemokine release than the others fibers tested. In summary, chicory inulin, sugar beet pectin, High-maize 260, and Novelose 330 attenuate S. paucimobilis-induced cytokines. These results demonstrate that dietary fibers with a specific chemical composition can be used to manage immune responses against pathogens such as S. paucimobilis.

Abstract
Sphingomonas paucimobilis is an aerobic Gram-negative bacillus that, although rare in humans, most commonly infects immunocompromised and hospitalized patients. Among the 59 pediatric cases of S. paucimobilis infection reported in the literature, the most common diagnosis involves isolated bacteremia. These cases are related to sporadic or epidemic infections. Death related to this infection occurred in only one case. The authors report a case of an 11-year-old boy with the diagnosis of Sphingomonas paucimobilis otomastoiditis and a thorough review of the literature on this infection in pediatrics. The patient presented a 20-day history of fever, otalgia, otorrhea, and progressive retroauricular swelling with protrusion of the left ear; despite 15 days of amoxicillin regimen. His past medical history included chronic bilateral otitis media, but no cause of immunosuppression was found. A brain computed tomography scan showed left otomastoiditis associated with a large circumscribed fluid collection with deep involvement of the soft tissues of the temporal region, including the subperiosteal space. Blood tests showed neutrophilia and elevated C-reactive protein. Surgical manipulation of the cited collection drained a large amount of a fetid purulent secretion. Ceftazidime and clindamycin were empirically initiated. The outcome was favorable, with fever defervescence and resolution of the scalp deformation. Culture of the drained secretion was positive for S. paucimobilis. Ciprofloxacin was scheduled for a further 10 days after discharge. The follow-up showed complete recovery. As far as we know, this is the first case of S. paucimobilis otomastoiditis, complicated with subperiosteal abscess in an immunocompetent child. The authors call attention to the increasing number of reports on S. paucimobilis infection over the years, and therefore to the importance of this pathogen, which was previously underestimated.

Abstract
Sphingomonas paucimobilis, formerly known as Pseudomonas paucimobilis, is a rare cause of septic arthritis and is therefore regarded as being of minor clinical interest in rheumatological diagnostics. In this connection the yellow pigmented, aerobic, glucose non-fermenting, Gram negative bacillus is usually associated with immunocompromised patients. A case of septic arthritis in a 70-year-old man with chronic obstructive pulmonary disease (COPD) initially presenting with right knee pain, swelling and redness is reported. After diagnosis of septic gonarthritis due to Sphingomonas paucimobilis, the infection was successfully treated by oral antibiotic therapy with ofloxacine based on the patient's antibiotic susceptibility profile, combined with analgesic and anti-inflammatory local physical therapy several times a day leading to a considerable improvement in the symptoms so that operative interventions could therefore be avoided.

Abstract
S.paucimobilis has a diverse nutritional substrate spectrum and found in both environmental and hospital settings. Sphingomonas paucimobilis is rarely isolated from clinical specimen. This low virulence organism since has been reported to cause a variety of diseases since 1979. It has been reported to be associated with both community acquired and nosocomial diseases including bacteremia, catheter related sepsis, diarrhoeal diseases, peritonitis, meningitis, cutaneous infections, endopthalmitis, visceral infections , urinary tract infections etc. We report two cases of community acquired primary bacteremia by Sphingomonas paucimobilis. One of the patients was 55-year-old female who had gallbladder carcinoma and the other was a 2-year-old healthy male who had no history of any underlying disease. Both got admission in hospital with complaints of pyrexia. Blood culture yielded S.paucimobilis which was found to be sensitive to quinolones, chloramphenicol, carbapenems, aminoglycosides and beta lactams except penicillin and amoxicillin.

Abstract
Sphingomonas paucimobilis is an aerobic gram-negative bacillus. The bacteria can cause infections, which can be devastating and, therefore, the patients need adequate and early antibiotic cover. We are presenting an interesting case of meningitis secondary to an unusual S. paucimobilis infection. This is the second case to our knowledge in the literature on meningitis due to S. paucimobilis. The 31-year-old previously healthy man presented with 2 months' history of weight loss and loss of appetite. He had fever and headache for 3 weeks. He was also speaking irrelevantly for 3 weeks. He had change of behaviour for 1 day. The patient was a farmer and worked in the soil. On examination, he was not responding to questions and was not obeying commands. Computed tomography (CT) brain with contrast revealed meningeal enhancement and cerebral oedema. Lumbar puncture was performed. Cerebrospinal fluid (CSF) opening pressure was more than 50 cm H2O. CSF analysis showed meningitis picture with raised white cell count of 210/μL (predominantly neutrophils), glucose 3.1 mmol/L, and raised protein 2.47 g/L. He was given intravenous ceftriaxone. The following day, his condition deteriorated. CSF culture grew S. paucimobilis sensitive to ceftriaxone. S. paucimobilis causes severe meningitis. This can lead to hydrocephalus, which results in a need for extraventricular drainage. A good occupational history is important with regard to finding the aetiology of serious meningitis (including rare bacteria) even before the culture result is known. Appropriate treatment can be given early and adequately to prevent mortality.

Abstract
Sphingomonas paucimobilis is a causative agent of infection in immunocompromised patients, and healthcare-associated infection. Although the infections associated with S.paucimobilis occurs rarely, it has been encountered with increasing frequency in clinical settings. In the current study we reported clinical features of the children with S.paucimobilis infection, and the antimicrobial susceptibilities of the isolated strains among the patients. This study was conducted in Dr. Behçet Uz Children’s Hospital, Turkey, during the period of January 2005 and December 2012. The medical records of pediatric patients with positive cultures for S.paucimobilis were reviewed. Sphingomonas paucimobilis isolates were recovered from 24 pediatric patients. The median age was 4 years (ranging from 3 days infant to 15 years) and 58,3% were male. Eight (33,3%) of the patients were under 1 months of age. Among the patients; 13 (54,2%) infections were community related however 11(45.8%) infections were nosocomial infection. The median duration of hospital stay was 7 days (ranging from 4 to 22 days). The most effective antibiotics were fluoroquinolones, carbapenems, and trimethoprim/sulfamethoxazole. This is the first largest study in children to evaluate the clinical features of S. paucimobilis infections. Sphingomonas paucimobilis may cause infections in both previously healthy and immunocompromised children. Although variable antimicrobial regimens were achieved to the patients, there was no attributable fatality due to S.paucimobilis infections due to the low virulence of the bacteria.

Abstract
BACKGROUND Sphingomonas paucimobilis is rarely isolated from clinical specimens and it is associated with a great variety of infections. The aim of this study is to investigate the microbiological and clinical features of S paucimobilis infection in southern Taiwan. METHODS S paucimobilis isolates from the microbiology laboratory of Chi-Mei Medical Center and their relevant clinical data from October 2005 to October 2009 were retrospectively reviewed. RESULTS A total of 55 patients with documented S paucimobilis infections were identified. Among them, 29 (52.7%) have community-acquired infections and 13 of them presented with primary bacteremia (44.8%). Multivariate logistic regression showed that community-acquired infection [adjusted odds ratio 13.473, 95% confidence interval (CI) 1.79-101.41, p = 0.01], diabetes mellitus (adjusted odds ratio 7.03, 95% CI 1.16-42.66, p = 0.03), and alcoholism (adjusted OR 10.87, 95% CI 1.00-117.69, p = 0.05) were significant risk factors for S paucimobilis primary bacteremia. Most of those who have health care-associated S paucimobilis infections presented with pneumonia (10 of 26, 38.5%) and only 7.7% presented with catheter-related infection. The overall mortality rate was 5.5%. CONCLUSION Community-acquired S paucimobilis infections were not uncommon, mainly presenting with primary bacteremia. Multivariate analysis showed that community-acquired infection, diabetes mellitus, and alcoholism were significant risk factors for primary bacteremia.

Abstract
Sphingomonas paucimobilis, is a yellow-pigmented, aerobic, non fermentative, gram negative motile bacillus. S. paucimobilis which is widely found in nature and hospital environments rarely cause serious or life threatening infections. In this report, a case of hospital acquired bloodstream infection due to S. paucimobilis in a patient with Down syndrome who was on treatment for presumed pneumonia is presented. A one year-old child patient who was a known case of Down syndrome and had previously experienced cardiac surgery was hospitalized and treated for pneumonia. On the 12th day of hospitalization, blood cultures were taken because of a high body temperature. One of the blood cultures was positive for gram-negative rods. After 48 hour of incubation, the sub-cultures on blood agar medium yielded pure growth of a yellow, non-fermentative, gram-negative, rod-shaped bacterium. The microorganism was positive for oxidase, and esculin hydrolysis, while negative for urea and nitrate reduction, citrate utilisation and motility. The isolate had been identified as S. paucimobilis by using Vitek 2 system. The antibiotic susceptibility test was also performed with the same system and the strain was found to be susceptible to piperacillin-tazobactam and other antibiotics. Treatment with intravenous piperacilin-tazobactam (150 mg/kg/day) was initiated. He responded well to the treatment and was discharged after 10 days. This case is reported to emphasize that S. paucimobilis should be kept in mind as a nosocomial infectious agent in patients with Down syndrome and immunosuppressive patients and the infections should be treated according to the sensitivity test results.

Abstract
BACKGROUND/PURPOSE Sphingomonas paucimobilis is a glucose-nonfermenting Gram-negative bacillus that is widely distributed in both natural environment and hospitals. Various infections in humans have been reported, but most have been limited to sporadic case reports. The aim of this study was to describe the clinical characteristics and manifestations of S. paucimobilis bacteremia. We also reviewed the literature on S. paucimobilis bacteremia. METHODS Cases of S. paucimobilis bacteremia were identified retrospectively at a university-affiliated hospital in Taiwan. In addition, relevant case reports were identified through PubMed and reviewed. RESULTS From April 2004 to April 2008, 42 cases of S. paucimobilis bacteremia were identified in this study. Among them, 16 cases were identified from E-Da hospital, Kaohsiung, Taiwan and 26 cases from the literature review. The median age of patients was 48.5 years and 57.1% were male. The most common comorbidities included malignancy (57.1%), immunosuppressant use (40.5%), and diabetic mellitus (11.9%). Hospital-acquired bacteremia accounted for 69.0% of infections. Primary bacteremia and catheter-related bloodstream infection were found in 35.7% and 33.3% respectively. The most effective antibiotics were fluoroquinolones, carbapenems, and beta-lactam/beta-lactamase inhibitor combinations. All 42 patients survived the S. paucimobilis bacteremic episodes, but three patients experienced septic shock. CONCLUSION S. paucimobilis can cause infections in healthy as well as immunocompromised individuals. Although it is an organism of low clinical virulence, infection caused by S. paucimobilis can lead to septic shock. Further clinical research is required to characterize this infection.

Abstract
Sphingomonas paucimobilis, a yellow-pigmented, aerobic, glucose non-fermenting, Gram-negative bacillus, is a rare cause of human infection normally associated with immunocompromised hosts. We report a case of bacteraemia and septic arthritis in a 47-year-old diabetic man who presented with septic pulmonary emboli due to S. paucimobilis. The patient had an initial presentation of fever, right knee pain, coughing, dyspnoea and chest pain. The infection was treated successfully by surgical debridement combined with meropenem plus ciprofloxacin, based on the patient's antibiotic susceptibility profile. To our knowledge, this is the first case report for septic pulmonary emboli having arisen from an S. paucimobilis infection.

Abstract
Bromhidrosis is a clinical disorder characterized by excessive or abnormal foul axillary odour due to the interaction of apocrine glands with micro-organisms which causes a serious personal and social handicap for affected people. We present the case of a 50-year-old caucasian female with bromhidrosis. The patient referred that this symptom had begun two months previously. Her past treatments included antibacterial soap, topical antibacterial agents and perfumes, but none of these relieved the patient of the odour. A cultural examination of axillary smear was carried out and it revealed the presence of ciprofloxacin sensible Sphingomonas paucimobilis. Therefore the patient was treated with ciprofloxacin and after 1 week the infection resolved completely.

Abstract
We describe a very rare case of chronic peritonitis with secondary adhesive intestinal obstruction caused by Sphingomonas paucimobilis in a healthy 28-year-old Chinese man. This bacillus has not been described as a cause of spontaneous peritonitis in healthy people. It was an asymptomatic, generalized, and slow-growing peritonitis causing peritoneal adherens and at the end intestinal occlusion that needed surgical adhesiolysis.

Liver autoimmunity triggered by microbial activation of natural killer T cells. Cell Host Microbe 2008; 3:304-15. [PMID: 18474357 PMCID: PMC2453520 DOI: 10.1016/j.chom.2008.03.009] [Citation(s) in RCA: 165] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2007] [Revised: 02/08/2008] [Accepted: 03/14/2008] [Indexed: 11/28/2022]
Abstract
Humans with primary biliary cirrhosis (PBC), a disease characterized by the destruction of small bile ducts, exhibit signature autoantibodies against mitochondrial Pyruvate Dehydrogenase Complex E2 (PDC-E2) that crossreact onto the homologous enzyme of Novosphingobium aromaticivorans, an ubiquitous alphaproteobacterium. Here, we show that infection of mice with N. aromaticivorans induced signature antibodies against microbial PDC-E2 and its mitochondrial counterpart but also triggered chronic T cell-mediated autoimmunity against small bile ducts. Disease induction required NKT cells, which specifically respond to N. aromaticivorans cell wall α-glycuronosylceramides presented by CD1d molecules. Combined with the natural liver tropism of NKT cells, the accumulation of N. aromaticivorans in the liver likely explains the liver specificity of destructive responses. Once established, liver disease could be adoptively transferred by T cells independently of NKT cells and microbes, illustrating the importance of early microbial activation of NKT cells in the initiation of autonomous, organ-specific autoimmunity.
