Assignment:
Leonys Martin, a Cleveland Indians outfielder, is recuperating as he battles a severe bacterial infection. Martin, 30, first began showing symptoms of the infection after playing in a game against the Minnesota Twins on August 7. The next morning, he was admitted to the Cleveland Clinic for nausea and stomach discomfort.
At the hospital, doctors diagnosed Martin with an infection that stemmed from bacteria in his bloodstream and impacted multiple organs. The infection - which the team has not publicly identified - was not from food and is not contagious, according to the statement.
Chris Antonetti, the president of baseball operations for the Indians, commented on Martin's condition at the player's wife's request, according to MLB.com, stating, "We don't know exactly how the bacteria entered his system.""It can't be transferred from one person to the next, but the bacteria somehow entered his bloodstream,"Antonetti said. "We don't yet know how. I'm not sure we will know how. But, once that bacteria entered the bloodstream, it produced toxins that led to him getting really sick."
The team wished him well on Twitter, and several players - including the White Sox's Jose Abreu - wrote Martin's name on their hats when the Indians played in Chicago, according to MLB.com.
1. What other illnesses do you know that have similar symptoms to Martin?
2. Why do you think it spread so quickly?
3. Do you believe that the infection is transferable even though officials say it is not? Why/why not?
Viral Infections
The diagram below illustrates how a virus infects a cell. A virus is piece of DNA or RNA that is surrounded by a protein coat. A virus encounters a cell then attaches itself and injects its DNA. Once injected, the viral DNA takes control of the cell machinery and forces the cell to manufacture (make) multiple copies of itself. Then, the viral DNA begins to make viral proteins that begin to replicate themselves, creating new viruses. Eventually this causes the host cell to die, and the virus is released to attach and infect more cells.
1. What happens when a virus infects a cell?
2. Do you think the virus is alive before, during or after it infects the cell? Explain.
3. What characteristics of living things do viruses exhibit? What characteristics of nonliving things do viruses exhibit?
