A method for identifying endogenous microbial proliferation genes for growth and viability is disclosed herein. The method involves exogenous nucleic acids that are used to conditionally produce antisense inhibitors of endogenous complementary mRNAs in a microorganism. Antisense fragments that result in lethality when expressed indicate that the endogenous gene is a proliferation gene. The method can also be used with sequences in sense orientation. The strategy can be used to identify new gene targets for novel antibiotics.

Methods for identifying anti-microbial agents

The sequences of nucleic acids encoding proteins required for proliferation are disclosed. The nucleic acids can be used to express proteins or portions thereof, to obtain antibodies capable of specifically binding to the expressed proteins, and to use those expressed proteins as a screen to isolate candidate molecules for rational drug discovery programs. The nucleic acids can also be used to screen for homologous genes that are required for proliferation in microorganisms other than The nucleic acids can also be used to design expression vectors and secretion vectors. The nucleic acids of the present invention can also be used in various assay systems to screen for proliferation required genes in other organisms as well as to screen for antimicrobial agents.
