Microorganisms belonging to
the Chlamydiaceae family are Gram-negative, obligatory intracellular
bacteria involved in diseases affecting both animals and humans.
family traditionally contained a single genus, Chlamydia (Bergey’s
Manual of Systematic Bacteriology vol.1, 1984) but in 1999 a new genus, Chlamydophila,
was added based on 16S rRNA and 23S rRNA sequence’s similarity (Everett et al.
in 1999). Furthermore, other five new species were proposed by Everett.
However, the use of the new genus name was debated within the scientific
community and for this reason the edition of the Bergey’s Manual (vol.4, 2011)
considers the genus Chlamydia the only genus and the five additional
species are classified within this genus. Since the taxonomy of the family Chlamydiaceae
is currently under consideration, and species with the name Chlamydophila
felis, Chlamydophila pecorum and Chlamydophila abortus have been
widely and validly published, the subdivision into two genera Chlamydia and
Chlamydophila has been retained in this collection until 2013. From
2014, only the genus Chlamydia is used.
Currently, the genus Chlamydia
encompass 10 recognised species: C.
abortus, C. avium, C. felis, C. gallinacea, C. pecorum, C. pneumonia, C.
psittaci, C. poikilotherma, C. suis, C. trachomatis. Other species have
been proposed in several publications but not yet accepted as such.
All strains enrolled in our
collection are submitted to different molecular and microbiology tests in order
to evaluate their purity and identity:
performed on cell cultures before freezing and after thawing in order to
evaluate the cryopreservation efficiency. The growth of the strains is
evaluated by qPCR and/or immunofluorescence test (IFT).
were tested by different molecular biology techniques, such as: specie-specific
real-time PCR that allow to confirm the purity and the identity of each
Quality management system
IZSLER laboratories, that
supply biological resources to IBVR, use testing methods performed according to
UNI EN ISO/IEC 17025 quality system.
