Which type of organisms cause diseases and infections?

1. Nonpathogenic

2. Pathogenic

3. Spirilla

4. Staphylococci

The correct answer is: Pathogenic

Pathogenic organisms are the type of organisms that cause diseases and infections. These organisms have the ability to invade the body and disrupt its normal functions, leading to various illnesses. In contrast, nonpathogenic organisms do not cause harm to the body and may even be beneficial. Spirilla and staphylococci refer to specific types of bacteria and are not definitive in causing diseases; they can be either pathogenic or nonpathogenic depending on the specific strain and conditions. However, the term "pathogenic" directly signifies the ability to cause diseases and infections, making it the correct answer in this context.
