Regarding candida true are -a) Commensal in skinb) Oral candidiasis common in pregnancyc) In AIDS at early staged) Gram’s Staining donee) Bladder candidiasis treated by Amphotericin by catheter
**Core Concept**
Candida species are opportunistic fungi that can cause infections in humans, particularly in individuals with compromised immune systems. They can inhabit various body sites, including the skin, mucous membranes, and gastrointestinal tract, often as commensals.
**Why the Correct Answer is Right**
Option B is correct because oral candidiasis, also known as thrush, is indeed more common in pregnant women due to hormonal changes and immunosuppression. Candida albicans, a common species of Candida, can colonize the oral mucosa and cause infection in these individuals. The increased estrogen levels during pregnancy can lead to an overgrowth of Candida, making oral candidiasis more prevalent.
**Why Each Wrong Option is Incorrect**
**Option A:** This statement is true, but it's not a unique characteristic of Candida. Many microorganisms, including bacteria and viruses, can inhabit the skin as commensals.
**Option C:** This statement is false. Candida infections are more common in advanced stages of AIDS, when the immune system is severely compromised. Early-stage AIDS patients may still have a relatively intact immune response, making it harder for Candida to cause infections.
**Option D:** This statement is false. Gram's Staining is not typically used to diagnose Candida infections. While Candida species can stain with Gram's Staining, it's not a reliable method for identifying them, as they can be misidentified as Gram-positive or Gram-negative bacteria.
**Option E:** This statement is false. While Amphotericin B is an antifungal medication used to treat Candida infections, bladder candidiasis is typically treated with antifungal medications that are administered orally or topically, not via catheter. Intravenous or oral administration is more common for treating systemic Candida infections.
**Clinical Pearl / High-Yield Fact**
Candida albicans can cause a range of infections, from superficial skin and mucous membrane infections to life-threatening systemic infections in immunocompromised individuals. Recognizing the risk factors and clinical presentations of Candida infections is crucial for prompt diagnosis and treatment.
**Correct Answer:** B. Oral candidiasis common in pregnancy.
