PHARMACOLOGY
MICROBIOLOGY:  
Metronidazole is a synthetic agent which is effective against a wide
range of
obligate anaerobes.  It is not effective against aerobes or
facultative anaerobes.
Against susceptible organisms, metronidazole is generally bactericidal
at
concentrations equal to or slightly higher than the minimum inhibitory
concentration.  The antibacterial activity results from the
disruption of DNA and
the inhibition of nucleic acid synthesis.  
The aetiology of bacterial vaginosis is unclear and changes in vaginal
flora which
accompany bacterial vaginosis are probably its manifestation rather
than its
cause.  Monitoring changes in vaginal flora by Gram stain slides of
vaginal
discharge smears may supplement diagnosis and assessment of treatment
efficacy by standard clinical criteria.
Metronidazole has been shown to have_ in-vivo_ and clinical activity
against:
-
Obligate anaerobic gram negative bacilli
