Table 2 Baseline sterility of the SHS hood immediately after donning. 6/50 (12%) of SHS hoods were contaminated with an organism. The bacterial overgrowth of Zone 1 on Hood 11 was agreed to be a contaminant
Swab of Zone 1 (3 × 3 cm on screen: n = 50) | Swab of Zone 2 (3 × 3 cm area on neck: n = 50) |
|---|---|
Hood 1: 1 CFU of Bacillus Sp. | Hood 3: 1 CFU of Bacillus Sp. |
Hood 11: Completely overgrown with a contaminant organism (> 100 CFU) (failed to identify) + 1 CFU of Bacillus Sp. | Hood 4: 1 CFU of Bacillus Sp. |
Hood 16: 1 CFU of Bacillus Sp. | Hood 11: 1 CFU of Bacillus Sp. |
Hood 23: Swarming colony unquantifiable + Paenibaccillus Glucanolyticus |
