Bacteroides fragilis is associated with the formation of intra-abdominal abscesses, whereas other Bacteroides species are rarely involved. Since bacterial clumping may contribute to the survival of bacteria in the face of host defence mechanisms, the hypothesis has been put forward that differences in aggregation between fragilis and non-fragilis strains of Bacteroides may account for their differences in survival in vivo. All seven B. fragilis strains tested formed aggregates within 4 h, but… CONTINUE READING
