Bacteria and Human Infections Matching

This question requires matching specific bacteria with the infections they commonly cause in humans. Let's analyze each bacterium:

P: Staphylococcus aureus

Staphylococcus aureus is a bacterium known to cause a variety of infections, including skin infections, pneumonia, and importantly, postoperative infections, often related to surgical wound complications.

Match: P - 3 (Postoperative infection)

Q: Shigella sp.

Shigella species are pathogenic bacteria primarily responsible for causing bacillary dysentery, characterized by severe diarrhoea, often accompanied by blood and mucus.

Match: Q - 4 (Diarrhoea)

R: Neisseria sp.

Certain species of Neisseria, particularly Neisseria meningitidis, are a leading cause of bacterial meningitis, a serious infection of the membranes surrounding the brain and spinal cord.

Match: R - 1 (Meningitis)

S: Yersinia pestis

Yersinia pestis is the bacterium infamous for causing plague, a potentially fatal infectious disease transmitted primarily through fleas.

Match: S - 2 (Plague)

Final Correct Combination

Based on the analysis, the correct matching is:

• P - 3 (Staphylococcus aureus - Postoperative infection)
• Q - 4 (Shigella sp. - Diarrhoea)
• R - 1 (Neisseria sp. - Meningitis)
• S - 2 (Yersinia pestis - Plague)

This corresponds to the combination P-3; Q-4; R-1; S-2.
