Laboratories that test human specimens for Chlamydiaceae
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.
A positive serologic test result is evidence that the bird was infected by Chlamydiaceae
at some point; on the other hand low titers doesn't confirm that the bird has a current active infection.
in cattle: commensals, trigger organisms, or pathogens?
A familia Chlamydiaceae
possui um ciclo de desenvolvimento bifasico unico, caracterizado por tres formas morfologicas distintas: corpo elementar (CE), corpo intermediario (CI) e corpo reticular (CR).
Furthermore, additional species of Chlamydiaceae
, namely Chlamydia pneumoniae and C.
antimicrobial resistance to tetracycline is rare, although a resistant strain of C psittaci recovered from ducks was reported.
We describe an apparently new disease in salamanders that is associated with a novel genus within the family Chlamydiaceae
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.
Two of these sequence clusters represented 10 and 5 of the samples, whereas no samples were represented in the cluster containing the Chlamydiaceae
, which includes C.
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.
Placentas and fetal organs were analyzed by histopathologic examination and by specific real-time PCR and immunohistochemical protocols that detect members of the Chlamydiaceae
family and P.
Our culture techniques coupled with outer membrane protein A (ompA) and 16S rRNA sequencing identified the constituents of mixed infections that represented new and emerging Chlamydiaceae
strains and clonal variants in human disease.
None of these 35 specimens was positive by immunohistochemical analysis with antibodies against Chlamydiaceae
psittaci seropositivity between women who had anti-Waddlia antibodies and those who did not, which suggests that Waddlia antibodies do not cross-react with Chlamydiaceae
