Abstract: The invention provides compositions and methods for identifying polynucleotides and polypeptides expressed by a microbe during infection or colonization. The invention also provides compositions and methods for identifying polynucleotides and polypeptides expressed by a host organism in response to a disease state. The invention also provides methods and compositions for the diagnosis, treatment, prevention, and amelioration of diseases and infections caused by microbes.
Abstract: The invention provides methods useful for identifying polynucleotides expressed in vivo by a microbe during infection of a host. Antibodies against antigens that are expressed by the microbe in vivo and in vitro are adsorbed with cells or cellular extracts of the microbe that have been grown in vitro. Unadsorbed antibodies are isolated and are probed against a phage display library of the microbe's DNA or RNA. A polynucleotide of the microbe that is expressed in vivo is isolated and identified.
