Which of the following represents the correct match of a sexually transmitted infection with its pathogen ?

Options

A. Syphilis - Treponema pallidum
B. Gonorrhoea - Entamoeba histolytica
C. Urethritis - Bacillus anthracis
D. Softsore - Bacillus brevis

Explanation

To solve the question about which sexually transmitted infection (STI) is correctly matched with its pathogen, we need to analyze the options provided. Here’s a step-by-step breakdown of how to arrive at the correct answer:

### Step 1: Understand the Question
The question asks for the correct match between a sexually transmitted infection and its corresponding pathogen. This means we need to identify the pathogen that causes each listed STI.

### Step 2: Identify the Options
Although the specific options (1, 2, 3, 4) are not provided in the transcript, we will use the information given about syphilis as an example.

### Step 3: Analyze Syphilis
- **Infection**: Syphilis
- **Pathogen**: Treponema pallidum (a bacterium)

### Step 4: Characteristics of Syphilis
- Syphilis is a bacterial infection transmitted through sexual contact.
- The first stage of syphilis can present with painless ulcers (also known as chancres) in the genital area.
- It can also lead to swelling of lymph nodes.

### Step 5: Confirm the Match
Based on the information, we can confirm that syphilis is correctly matched with its pathogen, Treponema pallidum. If one of the options listed in the question corresponds to this match, then it is the correct answer.

### Step 6: Evaluate Other Options
If there are other options provided, we would need to analyze each one similarly:
- Identify the STI and its pathogen.
- Verify if the pathogen is known to cause the listed STI.

### Conclusion
If option A (syphilis - Treponema pallidum) is among the options, it is the correct match. If other options are provided, we would need to evaluate them based on the same criteria.
