Fungus grow best at low pH and high osmotic pressure environments.

Which of the following is NOT the characteristic of an Acute Viral Infection?     

There are 5 types of RNA in bacterial cell.

Which of the following process is used by bacteria to transfer plasmids?

This type of persistent viral infection in animals is caused by slow release of the virus from infected cells without cell death. Examples of this type of infection include Hepatitis C and HIV (AIDS).

These phototrophic bacteria live in anaerobic mud at the bottoms of lakes and ponds that are rich in hydrogen sulfide. They have bacteriochlorophylls and are anaerobic (do not use oxygen gas) and anoxygenic (do not produce oxygen gas).

Match the protozoan to the disease or symptoms it causes.

This fungi is part of the human microbiota of the skin, intestine, ear, and genital tract. If it overgrows it can cause a vaginal yeast infection.

Different strains of bacteria can be classified based on the use of viruses that infect and destroy specific types of bacterial cells. If the virus infects and destroys that type of bacteria, a plaque will form on a lawn of bacterial cells grown on a petri plate. This is called:

All are ways to culture viruses except:
