''Chlamydia suis'' is a member of the genus ''
Chlamydia''. ''C. suis'' has only been isolated from
swine, in which it may be
endemic.
Glycogen
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. The polysaccharide structure represents the main storage form of glucose in the body.
Glycogen functions as one o ...
has been detected in ''Chlamydia suis'' inclusions in infected swine tissues and in cell culture. ''C. suis'' is associated with
conjunctivitis,
enteritis and
pneumonia in swine.
Some strains have enhanced resistance to
sulfadiazine
Sulfadiazine is an antibiotic. Used together with pyrimethamine, a dihydrofolate reductase inhibitor, it is the treatment of choice for toxoplasmosis, which is caused by a protozoan parasite. It is a second-line treatment for otitis media, p ...

tetracycline. Several strains of ''C. suis'' are known to have an extrachromosomal
plasmid
A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; how ...
, pCS. ''C. suis'' strains are somewhat more diverse than are other chlamydial species. The deduced ompA gene products of various ''Chlamydia suis'' strains contain vs4
epitopes TLNPTIAG(A.K.T)G(D.K.N.T), TWNPTIAGAGS or TLNPTISGKGQ. These epitopes are identical or nearly identical to the ''Chlamydia'' MOMP core epitopes NPTI, TLNPTI, LNPTIA or LNPTI, which are recognized by ''
Chlamydia trachomatis'' vs4 mAbs. They are also identical or nearly identical to TIAGAGD and IAGAG epitopes, which are recognized by ''C. trachomatis'' B-serogroup mAbs.
