History: 1805: First recorded outbreak in Switzerland. Gaspard Vieusseux described meningococcal meningitis. 1887: Anton Weichselbaum discovered meningococcus, also known as Neisseria meningitidis, the bacterium that causes meningitis. Big Outbreaks: 2012: 64 fatalities and 700 infected by fungal meningitis in Massachusetts from contaminated drugs. Recent Outbreaks:

meningitidis) was first discovered in 1887 by Weichselbaum from analyzing the cerebrospinal fluid (CSF) of a patient infected with meningitis. It is a human-specific bacterium that causes a multitude of illnesses, collectively termed meningococcal disease. In 1887, Anton Weichselbaum, a Viennese doctor, was the first to report the isolation of meningococci from patients with meningitis (1). Shortly after, came the first description of lumbar puncture in living patients (2), leading to the isolation of meningococci from acute cases of meningitis. Neisseria meningitidis (N.

Cases had Meningitis was first described in the 1020s in Avicenna's The Canon of Medicine, and again more accurately by Avenzoar of al-Andalus in the 12th century. Symptoms of the disease were also noted in Weichselbaum hasta 1887. En el siglo XX ocurrieron grandes epidemias durante la Primera y Segunda Gue-rras Mundiales.2 En el continente africano, particu-larmente en la región subsahariana, se han descrito epidemias de meningococo desde principios del mis-mo siglo, exacerbadas en sus últimas décadas por pe- Er entwickelte ein Reagens zur Serum- und Liquor-Proteinbestimmung (Weichselbaum-Biuretreagens). 1886 entdeckte er das Bakterium Streptococcus pneumoniae (früher Diplokokkus pneumoniae genannt) sowie 1887 den Erreger der vor allem bei Säuglingen und Kleinkindern auftretenden Meningokokkenmeningitis (Neisseria meningitidis, Diplokokkus intracellularis meningitidis, Weichselbaum-Diplococcus).

NEW YORK. The specific relation of the diplococcus of Weichselbaum to epidemic cerebrospinal meningitis is established beyond question. Investigations .

Neisseria meningitidis. is a leading cause of bacterial meningitis . and sepsis in the United States.

Symptoms of this disease were first noted in 1805, having been described as an epidemic cerebrospinal fever (Vieusseaux) but it was not isolated until 1887 by Weichselbaum (Weichselbaum). In the U.S. every year, there are approximately 3000 to 4000 cases of N. meningitidis linked meningitis (Wong et al). Because this bacterium poses a health threat, genome sequencing has already begun for a few of these strains to enable deeper understanding of its mechanism of infection.

Dr. Weichselbaum's research interests include mechanisms of tumor spread and how radiation therapy and immunotherapy can be used to better treat cancer. He is also studying patterns of gene expression in human tumors The historical record of cerebrospinal meningitis as a clinical and epidemiologic entity opens early in the 19th century with the description of an outbreak in Geneva, Switzerland, which began in March 1805, and another in Medford, Mass., during March 1806.Isolation of the causative organism by Weichselbaum 1 in 1887, confirmed by the extensive studies of von Lingelsheim 2 in 1905, permitted a The second, N. meningitidis, causes outbreaks of meningitis and septicemia.

Surprisingly, up to 10% of the general population carry the bacteria in their nose and throat without any adverse effects. Neisseria meningitidis (N. meningitidis) was first discovered in 1887 by Weichselbaum from analyzing the cerebrospinal fluid (CSF) of a patient infected with meningitis.

fection meningococcal es revistate. Es The present report deals with eleven cases of meningococcal arthritis which Weichselbaum, A.: Ueber die atiologie.

Weichselbaum was among the first to recognize the importance of bacteriology for pathological anatomy. Meningococcal infections presenting as meningococcal meningitis became a nationally reportable disease in the U.S. as early as the first part of the 20 th century 5 In the early 1900’s, between 69 and 90 percent of cases were fatal with fatality rates higher among children than adults.
