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.
It is an infection caused by a common type of yeast (or fungus) called candida. This yeast is found in most people's bodies. A healthy immune system keeps it under control. Candida usually infects the mouth, throat, or vagina. It can occur months or years before other, more serious opportunistic infections. See Fact Sheet 500 for more information on opportunistic infections. In the mouth, the infection is called thrush. When the infection spreads deeper into the throat it is called esophagitis. It looks like white patches similar to cottage cheese, or red spots. It can cause a sore throat, pain when swallowing, nausea, and loss of appetite.
