IgG 3 Levels in Patients with Chronic Membranoproliferative

Organisms of the genus Bacteroides occur as commensals in the oropharynx and female genital tract and are the predominant commensals of the large bowel (Wilson and Miles, 1964; Cowan and Steel, 1965). They are important causes of infection in and around these sites. Severe bacteroides infections are unusual but dangerous, and an important aspect of treatment is the correct choice of antibiotic. Lincomycin and clindamycin (Dalacin C) have been shown in vitro to possess bactericidal activity against Bacteroides species (Ingham et al., 1968), but we are unaware of any published clinical account of the use of this group of antibiotics in the treatment of such infections. We report here our experience of the treatment of bacteroides infection with these antibiotics. Six cases are described. In four the infection complicated gastrointestinal surgery, and one case of puerperal sepsis and one case of primary bacteroides lung abscess were encountered.
