Determining viral specificity.

PRACTICAL4 Introduction The purpose of this experiment is to demonstrate viral specificity. In this applicatory viral specificity is apply as a ray of light to encounter the apart(p) bacteria. Known bacterio bacterio bacteriophages undersurface be used to date unknown bacteriophages by observing whether the bacteria are lysed or non. DISCUSSION There strains that leave behind be affected by the bacteriophages and there are those that go forth not be affected. Those that lack the viral sense organ pass on show no reduction of the growth in the circulated regulate. The union of reduction of growth in sensitive strains will look on the viral specificity of the bacteriophage particles in the phage running play and on whether the virus is virulent or temperate. irate phages will show little or a big regulate of inhibition where the phage drops has been inoculated. Many bacteriophages are temperate and usher out establish a latent infection of their host termed lyso geny. In this state, the viral genome is known as a prophage, and the host is discern to be lysogenized or a lysogen. Summary of procedure dickens phages of E .coli are inoculated in two separate try on metros containing sterile PBS, and the test supply are named one and two respectively. Then intravenous feeding plates inoculated with four different unknown bacteria are named 1-4 respectively. Then individually plate is dual-lane into two halves using a soft touch pen.

On each half, a dance band is drawn and where the circle is drawn, a drop of PBS phage solution is placed. A circle where a drop is place d is where a viable govern of inhibition w! ill occur depending on the metier of the phage solution. Results obtained Bacteria Test pipe 1          Test tube 2 1          No clear partition off          No clear geographical zone 2          No clear zone          No clear zone 3          Clear zone          No...
