Drug resistance transmitting factor present in bacteria is :
**Core Concept**
The question is testing the understanding of the mechanism of antibiotic resistance in bacteria. The underlying concept is that bacteria can develop resistance to antibiotics through various mechanisms, including the presence of a drug resistance transmitting factor.
**Why the Correct Answer is Right**
The correct answer is related to the concept of R-factors (Resistance factors), which are small, self-replicating plasmids that carry genes encoding enzymes responsible for antibiotic resistance. These plasmids can be transferred between bacteria through conjugation, transformation, or transduction, allowing resistant bacteria to spread and multiply. The presence of R-factors is a major concern in the development of antibiotic resistance in bacteria.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the concept of drug resistance transmitting factors in bacteria.
**Option B:** This option is incorrect because it does not specifically relate to the mechanism of antibiotic resistance in bacteria.
**Option C:** This option is incorrect because it is not a recognized term in the context of antibiotic resistance in bacteria.
**Clinical Pearl / High-Yield Fact**
It is essential to remember that the spread of antibiotic resistance can occur through various mechanisms, including the transfer of R-factors between bacteria. This emphasizes the importance of proper antibiotic use and infection control practices to prevent the development and spread of antibiotic-resistant bacteria.
**Correct Answer: C. R-factors (Resistance factors)
