In an effort to minimize the risks for scientists working with these animals, a new isolation chamber was designed in a bio-safety lab. The chamber was designed mainly to separate the internal controlled environment from the external environment, and the operator from the experiment and the experimental products. The primary aim was to prevent crosscontamination from the internal to the external environment or vice versa (Kruse et al., 1991; Wathes and Johnson, 1991; Huang, 2005; Tattershall, 2006) . Isolation chambers were designed to improve experimental safety by preventing this cross-contamination, reducing the likelihood of operator error, and minimizing the contaminated area. In addition, the comfort level of scientists working with the isolation chambers was taken into account. The safety level of these chambers allows for the operator to avoid wearing too many protective suits, which improves both the comfort and flexibility of the operator (Sawyer et al., 2007) .
