Among the given viruses, which is best cultivated from urine?
**Core Concept**
Cytomegalovirus (CMV) is a member of the herpesvirus family, and its cultivation from urine samples is a well-established diagnostic approach. This is because CMV can infect various organs, including the kidneys, leading to viral excretion in urine.
**Why the Correct Answer is Right**
CMV can be isolated from urine samples, particularly in immunocompromised patients, such as those with HIV/AIDS or transplant recipients. The virus can be cultured using cell lines like human fibroblasts or endothelial cells. This method is particularly useful for diagnosing congenital CMV infection, where urine PCR is often used in conjunction with other diagnostic tools.
**Why Each Wrong Option is Incorrect**
**Option A:** Herpes simplex virus (HSV) can be cultured from various body sites, but it is not typically isolated from urine. HSV is usually diagnosed through PCR or viral culture from skin lesions or mucosal surfaces.
**Option B:** Coxsackievirus, a member of the enterovirus family, can be isolated from stool or respiratory secretions but is not typically cultivated from urine. Coxsackievirus infections often present with gastrointestinal or respiratory symptoms.
**Option C:** Adenovirus can be isolated from respiratory secretions, stool, or urine, but it is not the best choice for urine cultivation. Adenovirus infections often present with respiratory symptoms, and other body sites are more commonly sampled.
**Clinical Pearl / High-Yield Fact**
When culturing CMV from urine, it's essential to use proper biosafety precautions due to the potential for viral reactivation and transmission.
**Correct Answer: C. CMV**
