Inoculated attenuated Sabin vaccination Salk Inactivated multiply three revert two prophylaxis infantile paralysis myasthenia gravis Poliomyelitis 00000000000 Drag the text blocks below into their correct order. In contrast, oral polio vaccine (OPV), developed by an in the 1960s, contains virus and can be easily administered by mouth making it useful still in polio eradication programs in developing countries today. OPV poses many risks, however, such as the attenuated virus can people and spread to others or it can making this vaccine virtually unusable in the U.S. today. In the past, this disease often affected small children and was called poliovirus vaccine was developed by in 1954 and is now the form used for all U.S. childhood vaccinations due to its low risk to individuals being vaccinated. in vaccinated to a neurovirulent strain causing disease, neuromuscular paralysis. There are against polio. is an acute enteroviral infection of the spinal…
Choose all the true statements regarding coronavirus proteins. Vaccine preventable diseases include COVID-19. For coronaviruses, it is more likely to find evolving mutations in the portion of the spike protein than the nucleocapsid protein. Mutations in the genetic code for the spike protein will produce 3D changes that are more likely to affect vaccine efficacy than changes to the nucleocapsid protein code. The nucleocapsid protein interacts with viral nucleic acid specifically whereas the spike protein interacts with the host protein non-specifically.
3) Discuss the characteristics of retroviruses. How do they act? How is their action different from normal transcription? Give examples of retroviruses.
Knowing that retroviruses operate on the principle of reversing thedirection of transcription from RNA to DNA, propose a drug thatmight possibly interfere with their replication.
2009 H1N1 pandemic Multiple Answer: Choose all that apply to this diagram target cells for this virus are found in the digestive system The 2008 virus is a product of the reassortment of a human virus triple reassortment is implied This virus is used in phage therapy Only humans are involved in the reassortment process that results in new strains of this virus The 2008 virus in the diagram indicates that only Hemagglutinin was reassorted from an earlier strain of virus
please tell me how bacteriophage and animal viruses multiply. please add both lytic and lysogenic cycles for bacteriophage, all steps, and the outcomes of both. For animal viruses, please include all steps and briefly explain the differences between their nucleic acids. i am having a hard trouble understanding this information if you could please explain in way where a child would understand it that would be amazing
Oncogenic viruses may either carry oncogenes within their genome, or affect native genes within the cells they infect, thus having an effect on cell cycle regulation within host cells. 1) True 2) False
viruses:1. Why must primary cell cultures be restarted every so often when preparing primary cell cultures to observe morphological changes caused by cells infected by a virus? Why are tumor cells preferred? 2. Why are non-enveloped viruses generally more resistant to disinfectants than are enveloped viruses? 3. A public health physician isolated large number of phages from rivers used as a source of drinking water in western Africa. They physician is very concerned that humans might become ill from drinking this water, although she knows that the phages specifically attack bacteria. Why is she concerned?
Data shows that people living with non-communicable diseases (PLWNCDs) are already at a higher risk of severe complications from COVID-19, more likely to be hospitalized, and at a higher risk of death. To make matters worse, the conditions under which they are living during thepandemic have potentially compromised their health even further and increased their risk of falling victim to the virus a. Discuss FIVE factors which may have exacerbated the health of PLWNCDs during theCOVID-19 pandemic exposing them to greater risk. b. For any of the factors mentioned above, comment on TWO approaches that countries may use to curb these challenges.
3) Would mRNA vaccines be as effective against bacteria as they are against viruses? Why or why not? Questions related to SARS-CoV-2 Inhibitor Science Article (Zhang et al.) 1) What is the function of the viral main protease? 2) What is the amino acid recognition sequence that is cleave by this main protease? Indicate where this protease cuts? 3) Would interfering with this protease effect other proteases in human cells? 4) How closely related are the amino acid sequences between SARS-CoV-2 and SARS-CoV? What does this suggest about focusing research on inhibiting this enzyme?
