Meningococcal disease associated with the 2001 haj – update

Neonatal meningococcal conjunctivitis associated with meningococcal meningitis.

Two infants are described in whom identical strains of meningococcus were isolated from both the eyes and the cerebrospinal fluid. This suggests that the eye may be a portal of entry in at least some cases of perinatally acquired neonatal meningococcal disease and has important implications for the management of purulent conjunctivitis in the newborn.

Annual report of the Australian Meningococcal Surveillance Programme, 2001.

Since 1994, The National Neisseria Network has examined and analysed isolates of Neisseria meningitidis from cases of invasive meningococcal disease in Australia by means of a collaborative laboratory program. The phenotypes (serogroup, serotype and serosubtype) and antibiotic susceptibility of 338 isolates of N. meningitidis from invasive cases of meningococcal disease were determined in 2001....

Update on meningococcal disease with emphasis on pathogenesis and clinical management.

The only natural reservoir of Neisseria meningitidis is the human nasopharyngeal mucosa. Depending on age, climate, country, socioeconomic status, and other factors, approximately 10% of the human population harbors meningococci in the nose. However, invasive disease is relatively rare, as it occurs only when the following conditions are fulfilled: (i) contact with a virulent strain, (ii) colon...

The Complexity of the Haj

The Hajj os Calculus is a simple, nondeterministic procedure which generates the class of non-3-colorable graphs. Mansseld and Welsch MW] posed the question of whether there exist graphs which require exponential-sized Hajj os constructions. Unless NP 6 = coNP, there must exist graphs which require exponential-sized constructions, but to date, little progress has been made on this question, des...
