1. Standardize Milk . Milk is often standardized before cheese making to optimize the protein to fat ratio to make a good quality cheese with a high yield . 2. Pasteurize/Heat Treat Milk . Depending on the desired cheese, the milk may be pasteurized or mildly heat-treated to reduce the number of spoilage organisms and improve the environment for the starter cultures to grow.
An opportunistic infection is an infection caused by bacterial, viral, fungal, or protozoan pathogens that take advantage of a host with a weakened immune system or an altered microbiota (such as a disrupted gut flora).Many of these pathogens do not cause disease in a healthy host that has a normal immune system.n opportunistic infection is an infection caused by bacterial, viral, fungal, or protozoan pathogens that take advantage of a host with a weakened immune system or an altered microbiota (such as a disrupted gut flora). Many of these pathogens do not cause disease in a healthy host that has a normal immune system.
When our immune system is working, it controls these germs. But when the immune system is weakened by HIV disease or by some medications, these germs can get out of control and cause health problems. Infections that take advantage of weakness in the immune defenses are called âopportunisticâ.The phrase âopportunistic infectionâ is often shortened to âOIâ.IV weakens the immune system so that opportunistic infections can develop. If you are HIV-infected and develop opportunistic infections, you might have AIDS. In the US, the Center for Disease Control (CDC) is responsible for deciding who has AIDS. The CDC has developed a list of about 24 opportunistic infections.
