A contaminated food sample contains several different species of bacteria. A food microbiologist is interested in studying just one of these species. Describe the sequence of procedures that the microbiologist must perform in order to obtain a pure culture of the bacterial species of interest from this food sample. Detail all the necessary media and equipment.

You are a young M.D. and genetic researcher working in conjunction with the Human Genome Project. The charge of your laboratory is to research cures for genetic diseases. Recently the Centers for Disease Control and Prevention (CDCP) reported several cases of a new genetic disease dubbed the "Liver Quiver Syndrome." Even though little is known about the inheritance pattern of the disease, the
abnormal allele(s) cause(s) a defective protein in the membrane structure of the Golgi apparatus. This abnormal protein prevents the processing of a protein that would eventually be secreted from liver cells. Symptoms include a spasm-like condition of the liver. Thus the name "Liver Quiver Syndrome." This disease is almost always fatal, killing most victims by age 50. As a doctor and genetic researcher, discuss the genetic research that must first be completed before a cure can be found. What will be an ideal response?
