Nutrients are components in foods that an organism uses to survive and grow. Macronutrients provide the bulk energy an organism's metabolic system needs to function while micronutrients provide the necessary cofactors for metabolism to be carried out. Both types of nutrients can be acquired from the environment.acronutrients provide the bulk energy an organism's metabolic system needs to function while micronutrients provide the necessary cofactors for metabolism to be carried out.

Staphylococcus epidermidis is a gram-positive, coagulase-negative cocci that is a part of our normal flora. Consequently, it is a true opportunistic pathogen, as it requires a major breach in the hostâs innate defenses.
Epidermidis and aureus are the species names of the two bacteria in the Genus: Staphylococcus. They cause the most common medical device mediated infections.Therefore, it is very important to understand their characteristics and the differences between them. The causativeness, drug resistance, virulent factors, and identifying characteristics are different between aureus and epidermidis. Staphylococcus Aureus.hey are common on skin as commensal bacteria, and in the nose as well. However, aureus is resistant to most of the antibiotics. The bacteria can produce enterotoxins, and these enzymes are the virulent factors cause a vast range of diseases.
