Special instructions Strict attention to careful specimen collection is critical. Since fungi are slow growing, cultures are incubated up to four weeks and thus are subject to overgrowth by contaminating, more rapidly growing organisms. Specimens should not be left open to contamination by airborne bacteria and fungi.

Since some fungi may be either saprophytic or pathogenic, observation of the same fungi in repeated cultures is often important for interpretation. Also, the number of infecting organisms may be few, and some specimens may be devoid of the infecting fungi. For these reasons, it is important to send at least 3 specimens when a mycotic infection is seriously considered. If swabs must be used, send in a sterile tube with 2-3 drops of sterile saline or place in transport medium. If specimens must be held, refrigerate them.
