Lipopolysaccharide (LPS) and major outer membrane protein (MOMP); OmpA; pmp-gene and Dna-K like protein are the main targets for serological as well as molecular detection techniques. Psittacosis in human is a disease of increasing concern and occurs in both sporadic as well as epidemic forms. Psittacines, pigeons and turkeys mainly transmit the disease.
