Chapter 14 Neisseriaceae, Veillonella, parvobacteria and Capnocytophaga

Neisseriaceae

The Neisseriaceae include the genera Neisseria and Moraxella. Two species of Neisseria are human pathogens:

There are a number of non-pathogenic species, such as Neisseria sicca, Neisseria mucosa and Neisseria lactamica, which are members of the indigenous flora, including the oral mucosa. Hence, it is important to differentiate these from the pathogenic species from oral samples.

N. gonorrhoeae is the agent of gonorrhoea, the most frequently diagnosed venereal disease in western Europe and the USA. Gonococci frequently cause pelvic inflammatory disease (PID) and sterility in women, in addition to arthritis and sometimes septicaemia. N. meningitidis is the aetiological agent of meningococcal meningitis, a highly contagious disease associated with a mortality rate approximating 80% when untreated.
