Neisseria meningitidis strain N61_09

Neisseria meningitidis strain N61_09 is a pathogenic bacterium that is classified as a Gram-negative cocci and is typically found in pairs. It is an aerobic organism and is mesophilic, with an optimal growth temperature of 35°C. This strain possesses two membranes and lacks mobility, as it does not have flagella. N61_09 is primarily associated with humans (Homo sapiens) and is known to cause a range of severe health conditions including meningitis, sepsis, cellulitis, septicemia, and invasive meningococcal disease (IMD). The strain is responsible for various forms of meningococcal disease, which can manifest as bacterial meningitis and acute bacterial meningitis (ABM). Given the significant health effects associated with this bacterium, it is classified as a free-living organism in its ecological niche. The presence of a single replicon indicates a relatively simple genetic structure, which is common in many pathogenic bacteria. The health implications of N. meningitidis strain N61_09 underline its importance in public health, particularly in regard to outbreaks of invasive meningococcal disease. Understanding the traits of this strain can aid in the development of targeted interventions and treatment strategies to combat the diseases it causes. The distinct habitat and biotic relationships of N. meningitidis suggest a complex interaction with its human hosts, highlighting the need for ongoing research into its pathogenic mechanisms and epidemiology.
