Genome Sequence of Porphyromonas gingivalis Strain PK1924, a Model Strain for Coaggregation Studies
Porphyromonas gingivalis strain PK1924 is a well-established laboratory strain that has been widely used as a model organism for investigating interspecies interactions, particularly coaggregation with Fusobacterium nucleatum. This strain has played an important role in early studies of oral biofilm formation and microbial community development. PK1924 was originally isolated from a human subgingival site by Dr. W. E. C. Moore in 1982 and was subsequently maintained in the laboratory of the late Dr. P. E. Kolenbrander at the National Institute of Dental and Craniofacial Research (NIDCR). The genome sequence of strain PK1924 provides a valuable resource for studies of P. gingivalis biology, oral polymicrobial interactions, and comparative genomics.
