[[C. psittaci]] may be classified into eight [[serovars]] according to variation in the major outer membrane protein (MOMP): serovar A to F, WC and M56.<ref name="pmid9765811">{{cite journal| author=Vanrompay D, Butaye P, Sayada C, Ducatelle R, Haesebrouck F| title=Characterization of avian Chlamydia psittaci strains using omp1 restriction mapping and serovar-specific monoclonal antibodies. | journal=Res Microbiol | year= 1997 | volume= 148 | issue= 4 | pages= 327-33 | pmid=9765811 | doi=10.1016/S0923-2508(97)81588-4 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=9765811  }} </ref>. With recent advances in molecular diagnostic techniques,
There is no established classification system for psittacosis.
 
[[C. psittaci]] can be further classified into 20 [[Genotype|serovars]]. This  was proposed recently on the basis of both ompA sequence analysis and multiple loci variable number of tandem repeats analysis (MLVA),
