The Communicable Diseases Network Australia guidelines provide information for early clinical and public health management of meningococcal disease, including community outbreaks. While community outbreaks of meningococcal serogroup C infections have been reported, community outbreaks of meningococcal serogroup B infections have not been declared in Australia. Three cases of meningococcal serog...

Invasive meningococcal disease is nationally reportable in Canada. In recent years, a serogroup C genotype, designated electrophoretic type 15 (ET15), has been the most frequently isolated meningococcal genotype in Canada and has caused epidemics across the country. Between August 1993 and September 1995, there were 9 cases of invasive meningococcal disease caused by a variant of this genotype,...

CONTEXT Neisseria meningitidis is a common cause of meningitis and septicemia in infants worldwide. Whether a meningococcal C conjugate vaccine protects infants against the serogroup C strain is unknown. OBJECTIVES To determine whether a meningococcal C conjugate vaccine is safe and immunogenic and induces immunologic memory in infants. DESIGN Single-center, double-blind, randomized control...

The sneaky meningococcus is a bacterium that can cause terrible disease. Development of an effective vaccine has been extremely difficult. Meningococcal vaccines developed in the 1990s are based on bacterial capsule, shield protects bacteria and used to instruct our body combat this These work against four types meningococcus: A, C, W, Y. However, they do not B. Scientists had invent completely...

OBJECTIVES Myocardial failure, leading to inotrope-unresponsive shock, is the predominant cause of death in meningococcal and other forms of septic shock. Proinflammatory cytokines released in septic shock are known to have myocardial depressant effects. We previously showed that interleukin 6 is a major myocardial depressant factor in children with meningococcal septicemia. In the current stud...

An outbreak of 7 cases of group C meningococcal disease occurred during the last week of July and the first week of August 2001 in the southwestern part of The Netherlands. Characterization of the 7 patients' isolates by various typing methods showed that the isolates were identical, except for the expression of PorA. Isolates from 5 patients were PorA deficient. These results show that transmi...

Preadmission administration of antibiotics to patients with suspected meningococcal infection has decreased the likelihood of obtaining an isolate and has stimulated development of rapid and reliable non-culture-based diagnostic methods. The sensitivity of the conventional test card latex agglutination test (TCLAT) for detection of capsular polysaccharide has been reported to be suboptimal. In ...

We are presenting a case of isolated fulminant meningococcal sepsis with two and a half year old child. Initial symptoms were obscure and common to many medical conditions, but also previously described as symptoms of meningococcal sepsis. Unrecognizing the seriousness of the condition child died at home, within few hours after examination and discharge from the hospital. Autopsy and microbiolo...

Neisseria meningitidis, an exclusive pathogen of humans, remains the leading worldwide cause of meningitis and fatal sepsis, usually in otherwise healthy individuals. In recent years, significant advances have improved our understanding of the epidemiology and genetic basis of meningococcal disease and led to progress in the development of the next generation of meningococcal vaccines. This rev...

OBJECTIVE Early recognition of invasive meningococcal disease in children may be difficult. Extremity pain and refusal to walk (extremity symptoms) are uncommonly mentioned as clinical findings in children who present with this disease. We sought to determine 1) the frequency of extremity symptoms as part of the clinical presentation in children with invasive meningococcal disease and 2) whethe...
