Collection Requirements
ACCEPTABLE SPECIMENS:  deep wound aspirate, pus, CT guided aspirates, surgical sinus aspirate,  tympanocentesis fluid, AV shunt tips and peritoneal end of VP shunt, IUD, infected gortex grafts

Collect specimen as follows:

FLUID/PUS
1. Decontaminate skin with povidone iodine.
2. Using sterile technique aspirate fluid/pus with needle and syringe. Use CT-guided aspiration in appropriate cases.
3. Expel air bubbles before injecting at least 1 mL of aspirated fluid/pus into an Anaerobe Systems Transport tube (AS tube).

TRANSTRACHEAL ASPIRATION:
1. Cleanse and anesthetize skin.
2. Insert a large bore needle through skin of the neck and the cricothyroid membrane into the trachea.
3. Pass a small sterile catheter through the needle, and aspirate exudate
4. Transfer exudate into an Anaerobe Systems Transport Tube (AS Tube).
NOTE: Serious complications have been noted with the transtracheal procedure.

IUD
1. Visualize cervix with speculum without lubricant.
2. Remove mucous and/or secretions from cervix with swab and discard.
3. Remove IUD while attempting to avoid contaminating vaginal secretions.
4. Submit entire device in a sterile, screw-capped container.
NOTE: IUD's should be sent for culture ONLY when infection with ""actinomyces-like"" organisms is suspected.

1. Indicate source of specimen on request form.
2. Swabs are discouraged due to lack of utility.
3. Bacterial, AFB, and fungal cultures may be ordered on a single specimen if sufficient volume is submitted.

Shipping And Handling
Anaerobic specimen containers (AS Tubes) transported via the pneumatic tube station are prone to breaking.  Do not place more than one tube per bag.  Use additional packing material (foam sleeve) if sending via the pneumatic tube station otherwise send via a courier.  
DO NOT REFRIGERATE.
DELIVER IMMEDIATELY TO MICROBIOLOGY IN A TIGHTLY SEALED CONTAINER WITH NO EXTERNAL SPILLAGE.

Turn Around Time (TATs for Specific Labs Below May Differ)
Turn Around Time:
  • ASAP: 7 Day(s)
  • STAT: 7 Day(s)
  • ROUTINE: 7 Day(s)

Clinical Indications
Used to identify the etiologic agent(s) of infection.

Clinical Significance
Infection may occur in any organ or tissue of the body, and the types of infectious processes are many. These include the following: brain abscess, chronic otitis media and sinusitis, dental and oral infections, aspiration pneumonia, lung abscess, thoracic empyema, breast abscess, liver, subphrenic, and other intra-abdominal abscesses, appendicitis and diverticulitis and their complications, peritonitis, wound infections following bowel surgery or trauma, puerperal or postabortal sepsis, endometritis, tubo-ovarian abscess, perirectal abscess, necrotizing skin and soft tissue infections, gas-forming cellulitis, gas gangrene (anaerobic myonecrosis), and bacteremia.

Infections in these sites are usually caused by a mixture of both anaerobic and aerobic bacteria. Interpretation of heavily mixed cultures may be difficult. Guidelines for identification and susceptibility testing of isolates are based on specimen source, method of collection, and numbers of different isolates and specific potential pathogens present.

Transtracheal aspirate: Small quantities of oropharyngeal flora may be present (<1000 colonies/ml). Large quantities (>1000 colonies/ml) are considered consistent with infection.

IUD's are contaminated with normal vaginal flora. Culture is performed only to screen for presence of Actinomyces.

Limitations
Transtracheal aspiration is used to aid in the diagnosis of serious pneumonia or pulmonary infections where other noninvasive studies are inconclusive and anaerobic infection is suspected.

IUD culture is useful only to screen for presence of Actinomyces in symptomatic patients.

Methodology
Gram stain and culture for aerobic and anaerobic bacteria.
Includes identification and susceptibility testing when appropriate at additional charges.
CPT coding cannot be determined before the culture is completed.

Additional Information
Communication with Clinical Microbiology (684-2089) is necessary when unusual organisms such as Brucella, Bartonella, Actinomyces, Norcardia,or Legionella are suspected as special culture conditions and prolonged incubation may be required.
