Question

Which one of the following is not correctly matched?
(a)Diphtheria-Corynebacterium
(b)Elephantiasis-Wuchereria
(c)Plague-Paramyxo
(d)Lockjaw-Clostridium

Answer 1

This is a causative agent in respiratory acute disease which is usually transmitted from airborne droplets. Paramyxo has RNA as genetic material and this includes agents like measles, Newcastle disease, parainfluenza disease. All the left side are the diseases that are caused by bacteria.

Complete answer:
-Plague is caused by Yersinia pestis which is a gram-negative and non-capsulated facultative anaerobic microorganism which infects human and animal via the oriental rat flea. It can reproduce inside cells, so even if phagocytosed they can still survive because of the presence of antiphagocytic slime layers.
-Paramyxo is a virus paramyxoviridae that causes diseases like measles, mumps, respiratory syncytial viruses, and parainfluenza viruses. This virus does not undergo genetic recombination and antigenic variation.
-Diphtheria is also known as the bull neck. Elephantiasis is known as lymphatic filariasis. Plague is a deadly disease thus, known as the black death. Tetanus is also known as lockjaw because it makes it hard to open the mouth and in the swallow.

Additional Information: -There are different types of plague as follows:
*Bubonic Plague
*Pneumonic Plague
*Septicemic Plague
*Meningeal Plague
*Cellular Cutaneous plague
-In bubonic plague occurs when infected rodents or flea bite and bacteria spread through the lymphatic vessels of the infected human which causes acute inflammation and painful swelling of the lymph nodes. The bacteria reach the lymph node where it stimulates the expansion of lymph nodes is the characteristic lymphadenopathy ‘bubo’.
-In pneumonic plague causes infection of the lungs which causes coughing and sneezing and only a form of plague that can be transmitted from person to person.
-In septicemic plague, the bacteria enter the bloodstream directly and multiply there. when both bubonic and pneumonic plague left untreated can lead to the septicemic plague.

So, the correct answer is, ‘plague-Paramyxo.’

Note: -Paramyxoviridiae looks similar to orthomyxoviruses which are large in size and more pleomorphic containing only single-stranded RNA.
-Paramyxovirus is classified into:
Influenza virus
Parainfluenza virus: Mumps virus, Parainfluenza virus, Measles virus, and Respiratory syncytial virus.
