.1 List the signs and symptoms of sepsis, and explain the most common types of infections that develop in to septic shock. Make sure to include information to differentiate between gram-positive sepsis and gram-negative sepsis. Lastly, describe what the two conditions are that define the systemic inflammatory response syndrome of sepsis.
. List a viral, bacterial, and fungal microbe that can cause a respiratory infection. With these three microbes, include the following for each (16 points):
a. mode of transmission
b. disease symptoms
c. preferred treatment
d. a laboratory test that could be done to determine a patient has the microbe
Influenza viruses are an important cause of respiratory infection in humans and also infect other host species such as pigs and birds. The ongoing epidemic and pandemic threat of influenza virus infection to the human population is primarily caused by antigenic change and escape of the virus from immune mediated protection. Discuss the different mechanisms leading to these changes and provide an overview of the dynamics of infection and transmission between these different hosts.
I want a detailed reponse, thnks :)
The influenza A virus type H5N1 responsible for the recent outbreaks of bird flu has been detected in swine. This has caused some alarm, as swine can also harbor human influenza viruses. There is a fear that a pig co-infected with avian flu and a human influenza A vitus may give rise to a new virus that is as lethal to humans as bird flu, and also capable of human to human transmission. What is this process that could allow this to happen?
