Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Expert Solution & Answer

Answer to Problem 1Q

Correct answer:

Clostridium difficile is a most common cause of acute diarrhea and is associated with CDC due to its antibiotic resistance characteristics. Therefore, option (b) is correct.

Option (b) is given as “Clostridium difficile”.

Explanation of Solution

Justify reason for the correct statement:

There are some drug resistant pathogens are present in large intestine such as C.difficile. An antibiotic treatment may disrupt large intestine as antibiotic disturbs normal biota. Due to these bacteria produces two enterotoxins such as toxin A and B causes necrosis in intestinal walls and results in diarrhea as well as Clostridium difficile colitis. It is condition occurs in which inflammation occurs in colon.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “Salmonella”.

It is found in the intestine of humans and animals. It causes infections through contaminated food and water. It is does not CDC. Hence, it is a wrong answer.

Option (c) is given as “Cryptosporidium”.

It is microscopic parasite that can cause diarrheal disease in humans. Hence, it is a wrong answer.

Option (d) is given as “Shigella”.

It is bacteria which causes acute diarrhea in humans by ingestion of contaminated food and water. Hence, it is a wrong answer.

Hence, options (a), (c) and (d) are incorrect.

Conclusion

The bacteria Clostridium difficile is resistant to antibiotics and may cause Clostridium difficile colitis in which inflammation occurs in colon.

*Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below.
