1 and 4 are true for bacterial meningitis. E It often causes meningitis. It can infect the.

A major advantage of PCR is that it allows for detection of Hi and Nm from clinical samples in which the organism cannot be detected by culture methods such as when a patient has been treated with antibiotics before a clinical specimen is obtained for culture. The overall rates have been declining 1 2 since the introduction of vaccines against the three most common meningeal pathogens Haemophilus influenzae type b Streptococcus pneumoniae and Neisseria meningitides and by the introduction of.
