Explain the conditions needed for the growth of micro-organisms
food. micro - organisms need food to survive.
They like high protein food to survive, eg. poultry & fish.
Warmth. most micro - organisms need warmth & grow best at 20-40c.
Moisture. They need moisture to multiply. [
Air (usually) they need air to multiply. though some can without.
Time. A single M.O becomes two every twenty minutes. ========================== This varies
depending on the type of bacteria. For example, warmblooded animal pathogenic bacteria require a temperature of around 98oF, a correct entry site, and for the host to be susceptible to that type of bacteria. Thermo-phillic bacteria require extremely hot temperature to grow. Viruses require a healthy host cell in order to get its DNA/RNA replicated. Parasites require the host body to be healthy enough to sustain itself and the parasite.
