The substances were evaluated individually for total colony counts, hygiene indicator organisms, pathogenic organisms, and levels of aflatoxin.
The bacterial colony count were noted and the colonies were identified using standard microbiological techniques.
The colony counts in air cultures collected 10 cm, 50 cm, and 100 cm away from the endotracheal intubation site in the open suctioning group were significantly greater than the counts in the closed suctioning group (colony-forming units [CFU]/plate: 72.3 [+ or -] 142.4, 57.8 [+ or -] 144.9 and 15.7 [+ or -] 26.2 vs.
In our study, a high median microbial colony count [median 10.5 (IQR 3-16.8) colony forming units (CFU)/[cm.sup.2]] was detected (Figure 1).
On modified humic acid agar, colony count of actinobacteria in lichen sample from elevation of 2614 m was significantly more than those of other elevations (P<0.05).
Aerobic Colony Count. The test sample was prepared in the same way that they were prepared for aerobic and anaerobic spore-formers count.
Mean colony count for control in this study was within the range of counts measured in studies 1-3, suggesting that the chosen bacterial load appropriately mimicked the other studies.
In contrast, a manual colony count, the most common method for quantifying the number of stem cells or progenitors in a given sample, is highly variable.
