Question

1. If resident and transient bacteria are both found on the hands, why is the transient population generally more varied? 2. Would taking up gardening as a hobby be more likely to affect the nature of the resident population or transient population of bacteria on the hands? Why?

Answer 1

1. The resident bacteria ara usually found in the skin (deeper layers of epidermis) and cause no harm to us. It is also known as Normal microbiota. Eg : Yeast , fungi

• The transient bacteria are not usually found in skin, but only temporarily seen on the surface of the skin and may cause harm. It conatnis a large variety of organisms includes Gram positive and negative organisms. It depends on the hygeine of the individual.

   The resident bacteria are more stable and last for a long time , but the transient are more varied compared to the resident bacteria. It is because the transient bacteria depends on the hygeine of the individual. It may cause harm and transient bacteria last only until the person washes hand.

2. Transient population : Are seen on the surface of the skin and while gardening the skin will be in contact with soil and where the soil contains a large vareity of other bacteria.
