Step 1: Understand the causative agent of tuberculosis. Tuberculosis is primarily a bacterial infection caused by members of the genus Mycobacterium. While the most common causative agent is Mycobacterium tuberculosis, Mycobacterium bovis also causes tuberculosis, particularly in animals and sometimes in humans.
Step 2: Analyze the options. Entamoeba histolytica: Causes amoebiasis, not tuberculosis. Salmonella typhi: Causes typhoid fever, not tuberculosis. Mycobacterium bovis: Causes tuberculosis and is a known causative agent. Bacillus cereus: Causes food poisoning, not tuberculosis.

Kit Performance in an Outbreak
A researcher compiled the following information about the performance of a kit in an outbreak:
| Infection State | Kit Response |
|---|---|
| Disease (probability = 0.002) | Positive response (probability = 0.98) |
| No Disease | Positive response (probability = 0.03) |
The probability of detecting an infection for a positive result through the kit would be ______________________ (rounded off to three decimal places).
