RESUMO
Conjugal genetic elements in isolates of oral black-pigmented Bacteroides denticola (Prevotella denticola) and B. intermedius (P. intermedia) transfer tetracycline and penicillin resistance in the absence of plasmids. Transverse alternating-field electrophoresis of restricted chromosomal DNAs from transconjugants revealed arrangements indicating that transfer and insertion can involve more than one 60-kb copy of the elements and occurs at strongly preferred sites in the recipient chromosome.
