Chapter 32, Problem 14

The mosquito-borne Zika virus (ZIKV) is one of the most feared viruses for pregnant women. Recent statistics justify this fear: Infants born to mothers infected with ZIKV during pregnancy face a risk of up to 42 percent of developing birth defects, including microcephaly (an abnormally small head and decreased brain volume). What do we know about how ZIKV causes damage to the developing brain? Researchers recently developed a mouse model for fetal brain defects associated with human ZIKV infection. To determine the effect of ZIKV on the number of neurons in the brain, ZIKV was injected into the brains of developing mouse embryos. Neurons were identified by staining sections of brain tissue with antibodies against NeuN, a neuron-specific protein, and the number of NeuN-positive cells per mm2 in specific regions was quantified. The results of three independent experiments are shown in the graph below. Use the P value provided to determine if the difference is significant or not (* means P< 0.05). Based on these results, what can you conclude?

Hello, everyone here we have a question telling us provided the following features identify the correct option, which includes all features associated with the zika virus and zika virus gets its name from the zika force in Uganda. That is correct. In the zika is primarily spread by mosquito. That is correct. Oh, one of the effects of the zika virus is microcephalic Children. That is correct. P zika virus is a D n. A virus is not a d n a virus. It is a single stranded R N. A virus positive sense. Q. Zika virus is called. Zika fever is caused by the zika virus. That is correct. So M N O and Q are correct, which means our answer is D thank you for watching. Bye.

The mosquito-borne Zika virus (ZIKV) is one of the most feared viruses for pregnant women. Recent statistics justify this fear: Infants born to mothers infected with ZIKV during pregnancy face a risk of up to 42 percent of developing birth defects, including microcephaly (an abnormally small head and decreased brain volume). What do we know about how ZIKV causes damage to the developing brain? ZIKV is a Baltimore class IV virus. Based on this classification, what do you know about the structure of its genome?

Recent statistics justify this fear: Infants born to mothers infected with ZIKV during pregnancy face a risk of up to 42 percent of developing birth defects, including microcephaly (an abnormally small head and decreased brain volume). What do we know about how ZIKV causes damage to the developing brain? Researchers have determined that host cells possess several different surface proteins that can serve as virus receptors for ZIKV. If you were to repeat the experiment described in Figure 33.8 using ZIKV instead of HIV, how would you expect the results to be different? Explain.

Textbook Question

The mosquito-borne Zika virus (ZIKV) is one of the most feared viruses for pregnant women. Recent statistics justify this fear: Infants born to mothers infected with ZIKV during pregnancy face a risk of up to 42 percent of developing birth defects, including microcephaly (an abnormally small head and decreased brain volume). What do we know about how ZIKV causes damage to the developing brain? Several lines of evidence suggest that after ZIKV is transmitted to a pregnant woman via the bite of an infected mosquito, the virus then directly infects cells of the placenta, gaining access to the fetal brain. Following attachment, the virion would most likely enter the placental cell by: a. insertion via the mosquito's mouthparts b. endocytosis c. degrading the cell wall with lysozyme d. injection through a hollow, needle-like protein structure

What do we know about how ZIKV causes damage to the developing brain? Traveling and tourism have been badly affected in ZIKV-affected countries. What advice would you give a friend planning a trip to the Caribbean?

What do we know about how ZIKV causes damage to the developing brain? Draw a model to illustrate how the Zika virus genome is used to produce new virions. In your drawing, identify the steps required to replicate the genome and those used to produce mRNA. Also note where mRNAs that are used to produce capsid and envelope proteins are translated.
