Meningococci are exclusively human, gram-negative, bean-shaped aerobic diplococci that are best isolated on chocolate agar. Like most of the other members of its genus Neisseriae , these organisms are aerobic, non-motile, harbour oxidase enzyme, produce catalase, their growth is stimulated by CO 2 and humidity.
The disease is spread person-to-person through the exchange of respiratory and throat secretions (e.g., by coughing, kissing, or sharing eating utensils). Meningococcal bacteria can?t live for more than a few minutes outside the body, so the disease is not spread as easily as the common cold or influenza.
Meningococcal meningitis and septicaemia need urgent treatment with antibiotics and rapid admission to hospital. If treated promptly, meningitis and septicaemia are less likely to become life-threatening.Meningococcal meningitis can be fatal or cause great harm without prompt treatment; as many as one out of five people who contract the infection have serious complications.
Major research on disease:
Impact of vaccination on meningococcal epidemiology.Meningococcus bacteria are spread through the exchange of respiratory and throat secretions like spit (e.g., by living in close quarters, kissing). Meningococcal disease can be treated with antibiotics, but quick medical attention is extremely important.
