Consider the following statements : 1. Brucellosis is a viral infection that spreads from animals to people. 2. Diphtheria is a serious infection caused by strains of bacteria. Which of the above statements is/are correct? Correct Answer 2 only
The correct answer is 2 only.
Key Points
- Brucellosis:
- Brucellosis is a disease caused by a group of bacteria from the genus Brucella. These bacteria can infect both humans and animals.
- Brucellosis is a zoonotic infection. It is a bacterial infection that spreads from animals to people. It affects thousands of people worldwide. Hence statement 1 is not correct.
- Most commonly, people are infected by eating raw or unpasteurized dairy products. Sometimes, the bacteria that cause brucellosis can spread through the air or through direct contact with infected animals.
- Diphtheria:
- Diphtheria is a serious infection caused by strains of bacteria called Corynebacterium diphtheria that make toxins (poison). It can lead to difficulty breathing, heart failure, paralysis, and even death. Hence statement 2 is correct.
- The diphtheria toxin causes inflammation of heart muscle (myocarditis) and this can lead to death if not treated with Diptheria antitoxin and proper antibiotics.
- Diphtheria is a vaccine-preventable disease – the toxoid vaccine elicits an immune response against the toxin which is encoded by a tox gene of the pathogen.
- The increasing diversity of the bacterium species, the emergence of variant toxin genes and the progression of antimicrobial resistance may lead to an increase in the incidence of diphtheria.
