Fusobacteria are most often associated with the classic presentation of Lemierre's syndrome consisting of a sore throat, internal jugular vein thrombophlebitis, and septic emboli to the lungs. Unusual presentations due to the causative organism, F. necrophorum, may occur. We present such a case involving a 17-year-old male patient with pyomyositis and fasciitis due to necrobacillosis. Fusobacterium spp. should be considered in the differential diagnosis of cases involving sepsis syndrome and pyomyositis.

Fusobacterium necrophorum subspecies funduliforme is an obligate anaerobic Gram-negative rod causing invasive infections such as the life-threatening Lemierre's syndrome (sore throat, septicemia, jugular vein thrombosis, and disseminated infection). The aim of our study was to understand if and how F. necrophorum avoids C activation. We studied 12 F. necrophorum subsp. funduliforme strains isolated from patients with sepsis. All strains were resistant to serum killing after a 1-h incubation in 20% serum. The bacteria bound, at different levels, the C inhibitor factor H (fH). Binding was ionic and specific in nature and occurred via sites on both the N terminus and the C terminus of fH. Bound fH remained functionally active as a cofactor for factor I in the cleavage of C3b. Interestingly, patients with the most severe symptoms carried strains with the strongest ability to bind fH. An increased C3b deposition and membrane attack complex formation on the surface of a weakly fH-binding strain was observed and its survival in serum at 3.5 h was impaired. This strain had not caused a typical Lemierre's syndrome. These data, and the fact that fH-binding correlated with the severity of disease, suggest that the binding of fH contributes to virulence and survival of F. necrophorum subsp. funduliforme in the human host. Our data show, for the first time, that an anaerobic bacterium is able to bind the C inhibitor fH to evade C attack.

Lemierre's syndrome is a rare but a life threatening condition which affects young healthy individuals, was first described by Dr.Andre Lemierre in 1936. Incidence rates are between 0.6 and 2.3 per million population. It is found more commonly in males, with a male to female ratio of approximately 2:1. Its pathogenesis consists of the development of infectious thrombophlebitis in the internal jugular vein or one of its branches caused by a focal sepsis, mostly localized in the oropharynx, leading to generalized multiorgan metastatic infections, generally to the lung. This computerized tomography (CT) neck with intravenous contrast is from a 24 year old female who presented with a two day history of fever, hypotension and respiratory failure. The physical exam was positive for diminished breath sounds bilaterally on lung exam. Complete blood count revealed a leukocytosis of 16,200 u/L with 70% neutrophils and 9% bands, hemoglobin of 13.4mg/dl and severe thrombocytopenia with a platelet count of 34,000 u/L; comprehensive metabolic panel revealed sodium 140mmol/L, potassium 2.9mmol/L, bicarbonate 26mmol/L, blood urea nitrogen (BUN) 16mg/dl, creatinine 0.8mg/dl, calcium 7.2 mg/dl, albumin 2.4g/dl, total bilurubin 3.1mg/dl, AST 81 U/L, ALK 101 U/L, ALT 35U/L. CT chest revealed multiple cavitary opacities in both lungs. Blood cultures were positive for Fusobacterium necrophorum. CT scan neck showed a filling defect of the right internal jugular vein consistent with a thrombus and multiple enlarged cervical lymph nodes. Treatment is medical with intravenous antibiotics and anticoagulation. References: 1. Carlson ER, Bergamo DF, Coccia CT. Lemierre's syndrome: two cases of a forgotten disease.

Lemierre syndrome is a distinct clinical syndrome comprising oropharyngeal sepsis and fever, internal jugular vein thrombosis and remote septic metastases caused by Fusobacterium species. The mortality rate was historically high and although use of antibiotics led to a dramatic fall in incidence, a resurgence has been seen recently. A 14-year-old male developed Lemierre syndrome after tonsillitis. There was extensive leptomeningitis, especially over the clivus, causing 6th and 12th cranial nerve palsies, a clinical feature termed the 'clival syndrome'. He also developed an epidural abscess in the cervical spine, which was unsafe for surgical drainage. Conservative treatment with an extended course of antibiotics and anticoagulation for jugular vein thrombosis led to a good recovery. A 15-year-old female developed Lemierre syndrome after a persistent sore throat lasting 7 weeks. She had palsy of the 12th cranial nerve from clival osteomyelitis. She was treated with a 6-week course of antibiotics and anticoagulants leading to almost full recovery at 3-month review. Awareness of the potential neurological complications of Lemierre syndrome and prompt management are crucial in reducing morbidity and mortality in this 'forgotten disease'.

Rheumatic fever (RF), caused by untreated group A streptococcal (GAS) pharyngitis, is a major cause of morbidity and mortality throughout much of the less developed world and disadvantaged populations (Indigenous and other) in the developed world. Through systematic literature searches, our group has identified potential risk factors for RF and possible interventions for its prevention. The causes can be divided into biological factors, socio-economic, and lifestyle factors and health-care systems and services. Currently, the most promising medical areas look to be improving access to health care and introducing community and school-based sore throat interventions (which aim to diagnose and treat GAS pharyngitis). We could find no convincing support for skin sepsis causing RF. Overall evidence suggests that measures that aim to alleviate poverty and crowding may also reduce the incidence of RF. In comparatively rich countries such as New Zealand and Australia, urgent measures based on available evidence should be undertaken to reduce the very striking health disparity seen with RF and its sequela, rheumatic heart disease in our at-risk populations.

Necrobacillosis, often used synonymously with Lemierre's syndrome, is a form of abscess infection in the peritonsillar area associated with a thrombophlebitis and caused by the strict anaerobic species Fusobacterium necrophorum. The thrombosis formed affects the internal jugular vein, from which the bacteria are seeded out in the bloodstream and cause bacteremia. Septicemia is a common complication with an often fatal outcome. Necrobacillosis is very rare and is referred to as the 'forgotten disease'. It is probably frequently overlooked in clinical practice in its early and milder forms such as tonsillitis (sore throat) and peritonsillar abscess. F. necrophorum frequently participates in these infections and is thus suspected to have an etiological role in Lemierre's syndrome. Similarly, F. necrophorum seems to play an important role in noma (cancrum oris) and this disease is also included in the necrobacillosis complex. Diagnosis of infections of the necrobacillosis complex seeks to disclose F. necrophorum in swab samples or blood culture. The most commonly used therapy is metronidazole in combination with penicillin or amoxicillin. Clindamycin is also an option, especially in cases of penicillin allergy.

Although very rare in the UK, sepsis was the leading cause of direct maternal deaths during 2006-2008, with an increase in community acquired Group A streptococcal infection (CMACE 2011). Most deaths occurred in the postnatal period and were often preceded by a sore throat or other upper respiratory infection, with a clear seasonal pattern. An associated factor was women of BME origin (black or minority ethnic origin). More than half of the deaths followed birth by caesarean section. All antenatal and postnatal women should be offered advice on the signs and symptoms of life threatening conditions, including sepsis. Information should include the importance of good hand and perineal hygiene and of the need to seek immediate medical care if feeling unwell. Relevant NICE guidance should be disseminated and implemented as widely as possible. Greater priority should be given to ensuring all women, particularly those in the most vulnerable groups, are aware of how to access timely and appropriate care.

Fusobacterium necrophorum is a non-spore-forming gram-negative anaerobic bacillus that may be the causative agent of localized or severe systemic infections. Systemic infections due to F.necrophorum are known as Lemierre's syndrome, postanginal sepsis or necrobacillosis. The most common clinical course of severe infections in humans is a progressive illness from tonsillitis to septicemia in previously healthy young adults. A septic thrombophlebitis arising from the tonsillar veins and extending into the internal jugular vein leads to septicemia and septic emboli contributing to the development of necrotic abscesses especially in lungs and other tissues such as liver, bone and joints. In this case report, a previously healthy man with pneumonia and empyema due to F.necrophorum has been presented. A 22 year-old man suffering from sore throat for seven days was admitted to emergency department with ongoing fever and dysphagia for three days. On admission he was already taking amoxicillin-clavulanic acid and his complaints were relieved with continuation of therapy to a total of 10 days. However, five days after the cessation of treatment he developed productive cough, fever and generalized myalgia. On physical examination, there were crackles on right lower lung, and chest X-ray revealed pulmonary consolidation on the right middle lobe. Levofloxacin therapy was started based on the diagnosis of pneumonia. While polymorphonuclear leucocytes and intracellular gram-negative bacilli were seen in Gram stained sputum smear, sputum culture was reported as normal flora. Although the patient's status had started to improve with treatment, his condition deteriorated with development of fever and dyspnea. Chest X-ray revealed consolidation, pulmonary infiltrates, pleural effusion and air-fluid level on the right. Meropenem, clarithromycin and linezolid were initiated and a chest tube was inserted with the preliminary diagnosis of necrotizing pneumonia, empyema and type-1 respiratory failure. While there was no growth on bronchoalveolar lavage fluid culture, thoracentesis material inoculated into thioglycolate broth revealed turbidity. Further inoculation onto Schaedler agar which was incubated under anaerobic conditions, yielded growth of catalase negative, indol positive, gram-negative anaerobic bacilli identified as F.necrophorum by BBL Crystal system (Becton Dickinson, USA). The detailed history of the patient revealed that fish bone had stuck in his throat a week ago. Clarithromycin and linezolid were discontinued and he was recovered within six weeks of meropenem treatment. F.necrophorum infection should be considered in the differential diagnosis of persistent head and neck infections with rapidly progressive metastatic necrotic lesions especially in healthy young adults and clindamycin or metranidazol should be added to the treatment protocols.

We report a case of a previously healthy 33-year-old male who presented to his primary care physician with nausea, vomiting, diarrhoea and fever. One week prior to presentation the patient reported a history of sore throat which he presumed to be a viral infection and sought no medical attention. Upon hospital presentation, the patient was admitted and rapidly progressed to sepsis and respiratory failure. Goal directed therapy was initiated and the patient was intubated. Further clinical work up included blood cultures revealing Fusobacterium varium bacteraemia, and CT and ultrasound imaging demonstrated thrombosis of the internal jugular vein and septic pulmonary emboli. A diagnosis of Lemierre syndrome was made, and antibiotics as well as anticoagulation therapy were initiated. The patient's clinical condition improved with treatment, and he was discharged home on hospital day 12 with completion of an uneventful 4-week course of outpatient antibiotic and anticoagulation therapy.

A 15-year-old boy presented with signs of sepsis and a history of sore throat, fevers and shortness of breath. Full examination revealed an erythematous oropharynx and mild tonsillar swelling. He rapidly deteriorated requiring admission to intensive care. Blood cultures grew Fusobacterium necrophorum and an ultrasound scan performed for left neck tenderness confirmed internal jugular vein thrombosis. He was diagnosed with Lemierre's syndrome. This condition results from pharyngitis or tonsillitis with bacterial spread to the lateral pharyngeal space. Internal jugular vein thrombosis ensues with septic emboli and metastatic infections that most frequently involve the lungs. Although increasing in incidence, diagnosis is often delayed. We discuss why and describe its clinical presentation, investigations of choice and treatment strategies.
