This paper describes two cases of meningitis and two cases of brain abscess caused by anaerobic, gram-negative, non-spore-bearing bacilli (genus Bacteroides). The portal of entry of the infection into the central nervous system in our cases and in the majority of cases in the literature was chronic suppurative otitis media. In view of this portal of entry, it is of interest to note that various species of Bacteroides have been described as inhabitants of the nasopharynx1 whence the ear infection may be presumed to have arisen.
Meningitis of otitic origin is usually associated with the common, aerobic, pyogenic organisms. In
