PRACTICAL4 Introduction The purpose of this experiment is to demonstrate viral specificity. In this applicatory viral specificity is use as a hawkshaw to encounter the inexplicable bacteria. Known bacterio bacteriophages undersurface be used to date unknown bacteriophages by observing whether the bacteria are lysed or not. DISCUSSION There strains that leave behind be affected by the bacteriophages and there are those that leave not be affected. Those that lack the viral sense organ give show no reduction of the growth in the circulated regulate. The gist of reduction of growth in sensitive strains will attend on the viral specificity of the bacteriophage particles in the phage runnel and on whether the virus is virulent or temperate. irate phages will show little or a big zona of inhibition where the phage drops has been inoculated. Many bacteriophages are temperate and post establish a latent infection of their host termed lysogeny. In this state, the viral gen ome is known as a prophage, and the host is ordinate to be lysogenized or a lysogen. Summary of procedure 2 phages of E .coli are inoculated in two separate sieve 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 curing is drawn and where the circle is drawn, a drop of PBS phage solution is placed. A circle where a drop is placed is where a viable partition off of inhib ition will occur depending on the metier of! the phage solution. Results obtained Bacteria Test tubing 1         Test tube 2 1         No clear geographical geographical zone         No clear zone 2         No clear zone         No clear zone 3         Clear zone         No...
