  • The pYUB178 plasmid and the λ phage library of pYUB178::H37Rv cosmids were generously provided by Dr. William Jacobs, Albert Einstein University, New York, NY [ 20 ] . The cosmid library contains 30-50 kb fragments of M. tuberculosis genomic DNA generated by partial Sau 3A digestion cloned into Bcl I-digested pYUB178.

  • Because the recombinant clones contain integrated pYUB178::H37Rv cosmids, the following strategy was used to isolate cosmids corresponding to those in the sur2 and sur3 clones.

  • The PCR product was used as a probe for colony blots to find cosmids in the E. coli (pYUB178::H37Rv) library carrying at least a portion of the cosmid integrated in the sur2 clone.

  • In this study, the enrichment process resulted in the isolation of two strains containing small, integrated plasmids rather than the expected 30-50 kb cosmids [ 20 ] . Small plasmids corresponding to the integrated ones were present in the original E. coli (pYUB178:H37Rv) cosmid library.

  • This represents about 20 M. tuberculosis genome-equivalents given that ~225 cosmids contain one genome-equivalent of M. tuberculosis [ 20 ] .
