In spring conidia produced by maize are carried out by wind to infect new plants during the moist period. The dormant mechanism aid the pathogen for some unfavourable environmental conditions. According to Nowell (1997) observed

RABIES Abstract: Each year‚ approximately 55‚000 individuals worldwide die from an infection due to the rabies virus. Rabies is a life-threatening disease caused by an RNA virus that is usually transmitted to humans through bites from rabid animals. More recently‚ reports of transmission by means of organ transplantation have been reported. Since human rabies is nearly 100% fatal if prophylactic measures are not followed‚ an increased awareness of who should receive prophylaxis and

widespread in the United Kingdom in the early 1800’s. Before that‚ religious arguments against inoculation (the placement of something that will grow or reproduce) were advanced. In a 1772 a sermon entitled “The Dangerous and Sinful Practice of Inoculation”‚ the English theologian Rev. Edmund Massey argued that diseases are sent by God to punish sin and that any attempt to prevent small pox via inoculation is a “diabolical operation”. Some anti –

Growth on the agar allowed one to examine the specific colonies. Inoculation and growth in the liquid culture were done to examine both strains of Halobacteria in the aqueous solutions. DNA extraction was done to take DNA from the Halobacteria strains and examine their genotypes. The PCR reaction’s purpose was to locate

Introduction: Microbes‚ also called microorganisms‚ are minutes living things that individually are usually too small to be seen with the unaided eye. The group includes bacteria‚ fungi (yeast and molds)‚ protozoa and microscopic algae. It also includes viruses‚ those noncellular entities sometimes regarded as straddling the border between life and nonlife. People tend to related these microbes only with major disease such as AIDS‚ uncomfortable infections‚ or such common inconveniences as spoiled

This will form visible colonies of each organism which will be isolated from the other colonies present. b) Flame the inoculation loop before each transfer to avoid contamination. c) Using the inoculation loop‚ aseptically “pick off” the individual colonies on the isolation plate and transfer to new sterile medium.
