Concept explainers
To determine:
Why didn’t doctors treat Atsa with antibiotics, such as penicillin or tetracycline?
Case summary:
Hantavirus a bunyaviridae group of virus which causes acute hantavirus haemorrhagic fever in humans. It is spread by the infected rodents to humans whom come in contact with the contaminated rodent faeces and urine. Sigmodon hispidus a cotton rat is the carrier of the hantavirus. Hantavirus is a single stranded RNA virus. There is no any validated drug to treat hantavirus infection.
To determine:
Hantavirus pulmonary syndrome cases are often seen in the years following higher than average rainfall. Why it is so?

- You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick. 1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side? 2) What would be the internal (within the embryo) control for this experiment? 3) How can you be sure that the electroporation method itself is not impacting the embryo? 4) What would you do to ensure that the electroporation is working? How can you tell?arrow_forwardDescribe a method to document the diffusion path and gradient of Sonic Hedgehog through the chicken embryo.
