CHLAMYDIA TRACHOMATIS
CULTURE

Ref Range
Reflex Reason
Endocervix:
1. Remove exess mucus from the cervical os and surrounding mucosa
using a sterile swab and discard the swab.
2. Insert a second swab into the endocervical canal. Rotate the swab
for 10-30 seconds in the endocervical canal to ensure adequate
sampling.
3. Withdraw the swab carefully; avoid any contact with the vaginal
mucosa. (With this two-swab method, a quality specimen containing
adequate cells and free of mucus will be obtained. Grossly bloody
specimens are not desirable.)
Male Urethra:
1. Patient should not have urinated for at least 1 hour prior to
sample collection.
2. Insert the sterile dacron-tipped swab with fine-wire shaft 2-4 cm
into the urethra using a rotating motion to facilitate insertion.
3. Once inserted, rotate the swab gently using sufficient pressure to
ensure the swab comes in contact with all urethral surfaces. Allow
the swab to remain inserted for 2 to 3 seconds and withdraw.
Conjunctive (Eye):
Gently swab the lower conjunctiva with a sterile, dacron-tipped swab
with plastic or wire shaft to collect mucous membrane cells.
Nasal aspirates: Collected by intubation are a superior source of
the agent in infants with pneumonia.
Nasopharynx: Insert a sterile, dacron-tipped swab with fine-wire
shaft gently into one or both anterior nares to the posterior
pharynx, rotate to collect mucous membrane cells and withdraw.
Sputum: collect specimens in a sterile leakproof container.
Throat: swab the posterior pharynx vigorously with a sterile dacron-
tipped swab with plastic shaft.
Rectal Mucosa: Insert a sterile, dacron-tipped swab with plastic
shaft 1 cm past the anal sphincter, rotate it in firm contact with
the mucosal surfaces and withdraw. *Do not use swabs with wooden
shafts as the turpentine in the wood may be toxic to Chlamydia.
Inoculation of M4 Transport Medium for Culture:
1. Immerse swab into M4 Transport Medium (available from Specialty)
immediately after collection to stabilize potential Chlamydia and
inhibit undesirable bacterial and fungal overgrowth.
2. Break off (or cut) the excess shaft of the swab so that the cap
will fit tightly.
3. To help maintain chlamydial infectivity, ship to Specialty on
cold pack within 24 hours of collection (for longer transport, freeze
at -70 deg C and ship on dry ice).
4. Dacron or rayon swabs are preferred for collection. Calcium
alginate and some cotton swabs as well as swabs with wooden shaft
have been shown to be toxic to Chlamydia.
Please supply patient's birth date on Specialty's Test Requisition Form for Public Health Department reporting. Urine is not acceptable for culture. Chlamydia trachomatis DNA by Ligase Chain Reaction, #7437 is recommended.
