Vedclass · Answer

(B) Diarrhoeal diseases involve the frequent and excessive discharge of watery stools from the bowel.These diseases are primarily caused by the ingestion of harmful pathogens through contaminated food and water.$Escherichia$ $coli$,$Shigella$ $sp.$,and $Salmonella$ $sp.$ are well-known bacterial pathogens that cause diarrhoea.Diarrhoea caused by these organisms involves two main mechanisms: first,the pathogens colonize the intestine,causing inflammation (enteritis); second,they disrupt the balance of intestinal fluid absorption and secretion,significantly increasing fluid loss,which manifests as frequent,watery stools.Dehydration is a common and dangerous consequence of all types of diarrhoeal diseases.Therefore,maintaining an adequate supply of fluids and electrolytes is essential for the management and treatment of these conditions.Since both statements are factually correct but the reason describes the management of the disease rather than explaining why these specific bacteria cause the disease,the correct option is $B$.

Assertion: $Escherichia$ $coli$,$Shigella$ $sp.$ and $Salmonella$ $sp.$ are all responsible for diarrhoeal diseases.
Reason: Dehydration is common to all types of diarrhoeal diseases and adequate supply of fluids and electrolytes should be ensured.
