Enterobacteriaceae The family Enterobacteriaceae contains some organisms living in the intestines without harming the host and some organisms that are harmful to the host. Using the South University Online Library or the Internet, research about Enterobacteriaceae. Based on your research, respond to the following: What is meant by the term `enteric pathogen`? Why are anaerobic organisms generally not seen in a routine fecal specimen or culture? What are the indole test, methyl red test, voges-proskauer test and citrate test (IMViC) reactions? Describe in detail all four reactions (what media is used, important ingredients, what each reaction measures, and what positive and negative results mean). Create a flowchart for the isolation and identification of specific enteric bacteria from fecal samples. Respiratory Tract Infections Respiratory tract infections are the chief cause of absenteeism in schools as well as places of work. From the common cold to the more serious bronchitis, respiratory tract infections are usually infectious and thus easily passed on from one person to another. Your assignment is to research on diseases of the respiratory tract, using the South University Online Library or the Internet. Based on your research, respond to the following: Classify respiratory tract diseases, their causes, and the pattern of associated symptoms. How are infections of upper respiratory tract different from those of lower respiratory tract? Why are infections of the upper respiratory tract milder as compared to those pertaining to the lower respiratory tract? Describe the curative methods for each of upper and lower respiratory tract infections. What are three specific factors that help clearing the lower lung of infectious agents?
