  1. Pseudomonas infections are diseases caused by a bacterium from the genus Pseudomonas. This bacteria is found in the environment, such as in soil, water and plants. This bacteria favors moist areas such as sinks, toilets etc. It resides in the ears, skin and intestines of people. It’s one of the common pathogens that’s involved in hospital infections. It’s called a opportunistic pathogen because it doesn’t cause diseases, but freely multiplies in persons whose immune systems are weakened by an illness or medication. This infection can be spread within hospitals by healthcare workers, medical equipment, sinks, disinfectant solutions and food. Many of the Pseudomonas bacteria are resistant to certain antibiotics, which makes it very difficult to treat. This bacteria is able to infect many parts of the body and several factors that make it a strong opponent include: it’s ability to stick to cells, minimal food requirements, resistant to many antibiotics, production of proteins that damages many tissues and a productive outer coat. “It is one of the most common forms of life on the planet, and it often gets into cell cultures and wrecks them” (Preston 185). “ The wild bacteria will consume the cell culture, eat it up, and make a variety of different smells in the air while their growing” (Preston 184). The characteristic smell of this bacteria can be sweet grape smell and sometimes corn or taco like odor. It was a mistake for them to smell the virus because it could be a serious virus of Marburg and Ebola, which means that there is a possibility that it’s airborne. Since they have smelled the bacteria they can be possibly infected with the Ebola virus within a few days.

  2. There is a technique to smell any chemical or anything that is in a flask which is to waft the air (Smelling a Chemical: The Wafting Technique, 2010). By the text ,Mr. Geisbert and Mr. Jahrling smelt the flask directly. Mr. Jahrling did waft the air towards him, but he sniffed it. It was a human reaction of curiosity, because objects should have a scent. It's just dangerous to directly smell anything in a lab setting; things can combine to create dangerous things that no normal human can comprehend. When people go into a lab they should already know that their lives could be in danger, therefore, they should have a sense of impending doom somewhere deep in their minds.
