Coxsackie virus can be isolated by inoculating into:
**Core Concept**
Coxsackie virus is an enterovirus that can cause various diseases, including hand, foot, and mouth disease. The isolation of Coxsackie virus involves culturing the virus in a suitable host system.
**Why the Correct Answer is Right**
The correct method for isolating Coxsackie virus is by inoculating it into **mouse sucklings** or certain cell lines, but among the common options, **mouse sucklings** and **cell cultures** like RD cells are preferred methods due to their susceptibility to the virus.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely incorrect as it's not specified, but typically, **embryonated eggs** are not the primary choice for Coxsackie virus isolation.
**Option B:** Similarly, without the option text, we can't directly address it, but **chicken embryos** are also not the first line for isolating this virus.
**Option D:** Assuming this involves an inappropriate host, it would be incorrect due to the specificity of Coxsackie virus to certain cell types or animal models.
**Clinical Pearl / High-Yield Fact**
It's crucial to remember that Coxsackie viruses are divided into groups A and B, with different pathologies associated with each, such as aseptic meningitis and myocarditis.
**Correct Answer:** D. Mouse sucklings or cell culture, but the exact answer choice isn't provided, so assuming **Correct Answer: D** based on the given instruction.
