Infectious diseases are transmitted from person to person by direct or indirect contact. Certain types of viruses, bacteria, parasites, and fungi can all cause infectious disease. Malaria, measles, and respiratory illnesses are examples of infectious diseases.
The correct answer is B. Campylobacter
Explanation:
Guillain-Barre syndrome is a disease in which the nerves and muscles are weakened usually as the immune system attacks them which leads to changes in muscles strength, pain, and even life-threatening conditions. Although the causes of this syndrome have not been completely determined in most of the cases the condition seems to be triggered by an infection and around 30% of people who experienced an infection before the syndrome had an infection caused by Campylobacter, which suggests the syndrome is related to this type of bacteria, although it has been also linked in few cases with influenza virus, Zika virus and others.

Answer:
The correct answer will be option D- blocking Cl channel.
Explanation:'
Quinidine is a stereoisomer of quinine derived from the bark of Cinchona plants which is used in the medication of the heart as class I antiarrhythmic agent. This alkaloid decreases the automaticity and increases the duration of the cellular action potential of the heart.
This alkaloid acts by blocking the neurotransmission through blocking of sodium and potassium channels responsible for the depolarization in non-nodal tissues like atrial cells, ventricular cells. This decrease in the neurotransmission of an action potential depends on the Ca⁺² ions and the quinidine can also act by blocking the Ca⁺² channels as well as B adrenergic receptor.
Thus, option D-blocking Cl channel is the correct answer.
