Transduction is a process monitored by viruses to transfer bacterials genes, most commonly through horizontal gene transfer.Bactiopages or phages, which is a bacteria infected by a virus, can be virulent (cause host cell lysis) or temperate (do not kill the host). Phages can either go through Specialized transduction or Generalized transduction. For Specialized transduction, a temperate phage uses the Lysogenic cycle to attach to the host bacteria and inject its DNA. At a specific integration site

have virucide: target viruses best * Kill several mechanisms * Damage proteins * Can damage plasma membrane * Can damage nucleic acid * Static agents – DO NOT KILL, but can stop growth * Cidal agents – ALWAYS KILL * Sepsis and Asepsis * Indicates bacterial contamination * Translated to purid * Asepsis: free from significant contamination * Aseptic technique II. The Rate of Microbial Death: Bacteria usually die at a constant

infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite? The nick names for the infectious agent that causes infectious disease names are; hepatitis Immunization, Havrix, VAQTA. Hepatitis is an acute infectious disease that can harm the liver. Several diseases of the liver, collectively known as hepatitis, are caused by viruses. The viruses involved, five of which have been reasonably well characterized, come from a wide range of

Tetanus Tetanus is a potentially fatal disease that is rooted throughout all of human history. It is caused by a bacterium that can be contracted in a number of ways. While the human interaction and symptoms are not caused directly by the bacterium affecting human tissue as with normal bacterial infections. Instead, the symptoms common with the infection are caused by a reaction to a neurotoxin called Tetanospasmin (Wells). The symptoms of this toxin on the body are a result of the toxin binding

micro organisms found in milk vary considerably, and are dependent upon the specific conditions associated with a batch of milk. Bacteria, yeasts, moulds, and bacteriophages are commonly encountered. Other viruses and Protozoa are seldom observed in milk products, except as occasional contaminants. 3. Mention the pathogenic bacteria present in milk. The pathogenic bacteria that are present in milk are Listeria Monocytogenes, Yersinia Enterocolitica, Campylobacter Jejuni Mention and explain

identified reasons these creatures were immune to infection. Like humans, they have a natural defense system against invading bacteria, viruses, and fungi, which involves a group of proteins called the complement system. So Dr. Merchant tested his theory by exposing the alligator blood to pathogens such as HIV, West Nile Virus, and E Coli. His results- it started to kill the bacteria. As it turned out the alligator complement system is much more effective than that of humans. The problem: no possibility

Practicing good hand hygiene and covering mouth while sneezing can help. Not sharing drinking glasses and eating utensils with others will keep the level of contact of harmful bacteria away. Getting ample amount a sleep, eating a healthy diet and regular exercise would help the body’s immune system to stay strong to fight off bacteria. Getting vaccinated before traveling abroad is a way to protect yourself from bacterial in foreign lands. If you have been around someone sick with meningitis it would be

Bioterrorism is the use of harmful substances to seriously hurt or kill another person. Schmalleger (2013) accurately defines bioterrorism as the “intention or threaten use of viruses, bacteria, fungi, or toxins from living organisms to produce death or disease in humans, animals, or plants” (p. 591). This form destruction can easily spread to mass quantities of people in a timely fashion making it a great concern among our law enforcement and other agencies. There are many forms of bioterrorism
