We both asked these questions yesterday but we are both confused.
1.Giardiaqsis is a communicable illness
transmitted:
A. through direct and indirect
contact with infected fecal
material.
(or)
B. by touching the moist lining
of the eyes and nose.
2. Lyme disease is caused by:
A. a parasite
(or)
B. a virus
We are confused with the first question
because we are thinking giardsis can be
transmitted by touching the moist lining of the nose and mouth. We know it is transmitted through direct and
indirect contact with infected fecal
material. Would the correct answer be
(A) or (B)?
2. Lyme disease is a bacterial illness,
but is it caused by a virus or a
parasite?
Aren't the infected ticks a parasite?
But a bacterial illness is a virus,
isn't it?
Which would be the correct answer for
the second question?
a virus, or a parasite?
Please reply, we both are confused!
I think you mean Giardiasis. This is caused by a type of single-celled organism called a protozoon that lives in the gut. It is one of the world's most common causes of diarrhoeal illness and is spread by ingesting fecal contaminated materials.
Lyme disease as you say is a bacterial illness carried by a tick. Bacteria are not viruses.
This should give you enough information.
I apologize for the confusion. Let me clarify the answers to your questions.
1. Giardiasis is indeed a communicable illness transmitted through direct and indirect contact with infected fecal material. The correct answer would be option A. Although it is possible for the infection to be indirectly transmitted through touching the moist lining of the eyes and nose with contaminated hands, the primary mode of transmission is through contact with infected fecal material.
2. Lyme disease is caused by a bacterium called Borrelia burgdorferi, which is transmitted through the bite of infected ticks. Ticks are parasites because they feed on the blood of their hosts, but the disease itself is caused by a bacterium, not a virus. Therefore, the correct answer for the second question would be a bacterium, not a virus or a parasite.
To further clarify, bacteria and viruses are different types of microorganisms. Bacteria are single-celled organisms that are capable of reproducing on their own, while viruses are smaller and can only replicate within the host cells. Lyme disease is caused by a specific bacterium, not a virus.
I hope this explanation clears up your confusion. Let me know if you have any further questions!
