.....culturing viruses that requires a human host

Answer:

Diploid cell culture lines, developed from human embryos, are widely used for culturing viruses that require a human host

Explanation

Viruses can not thrive in a non-living host or artificial media.They  are intracelular parasites  which needed living host to replicate . Cultures lines from Human embryo  in are therefore used for culturing viruses of human host, so that its mode of replication and gene expression can be studied, and therefore its virulence can easily be studied.

This method have the advantage that;

1.there is no need to make use of the whole animal rather,on a tiny tissue needed can be isolated for culture.

2. the cells growth is continuous,and can be preserved in liquid Nitrogen and renew for future culture

3. cells can be grown in different containers,  with ability to decide the number of cells needed.

Temperature is kept at optimum for human in the culture at  37 degree centigrade, nutrients are provided, NaHC03 as buffers for C02, and  the medium is humidified.

  • Proper eyelid cleanliness stops the bacterial buildup that leads to blepharitis and the potential for Demodex.
  • Maintaining clean eyelids and lashes is also essential for safeguarding the many glands that line our eyelids and aid in the production of our tears.
  • To allow the fluid to move across the eye, someone should flush their eye for 10 to 15 minutes while attempting to keep their eyes open.
  • Some chemicals, such strong alkalis, may call for 60 minutes of flushing.
  • When flushing the eye, one should make sure there are no chemicals or debris under the eyelid by looking around. They might want to get medical help after flushing.
