All strains of
Chlamydiaceae share an identical genus-specific antigen in the lipopolysaccharide of their cell wall but differ in the composition of other cell-wall antigens, which accounts for the different serotypes.

Chlamydiaceae antigen (fluorescent antibody) in feces, a cloacal swab specimen, or respiratory tract or ocular exudates.
O isolamento da bacteria e o metodo recomendado para o diagnostico de microrganismos da Familia
Chlamydiaceae. Em se tratando de uma bacteria intracelular obrigatoria, necessita de cultura celular.
Chlamydiaceae in cattle: commensals, trigger organisms, or pathogens?
Although some
Chlamydiaceae screening tests and strain-typing methods exist, they are expensive, are time-consuming, require trained personnel, and are available only in specialized laboratories; most do not discriminate among species of
Chlamydiaceae.
Transmission electron microscopic examination of the liver of a yellow spotted newt revealed intracellular inclusions containing particles matching the morphology of reticulate or elementary bodies of
Chlamydiaceae (online Technical Appendix, wwwnc.cdc.gov/EID/pdfs/111137-Techapp.pdf).
A tale of discrimination: differentiation of
Chlamydiaceae by polymerase chain reaction.
To test the placental specimens, we used a commercial
Chlamydiaceae family-specific monoclonal antibody directed against the chlamydial lipopolysaccharide (clone AC1-P; Progen, Heidelberg, Germany) at a dilution of 1:200.
Despite the short sequence length of the 15 samples, the tree was well resolved with the Chlamydiales sequences and formed 3 clusters (
Chlamydiaceae, Rhabdochlamydiaceae/Simkaniaceae, and Parachlamydiaceae/Waddliaceae/Criblamydiaceae) (Figure).
trachomatis MLST schemes, we used complete genomic comparisons of 7 strains from 4 species within the family
Chlamydiaceae to identify conserved candidate housekeeping genes across the genomes.
