The virus cells are injected with the DNA intended to help the patient. The viruses are also given the capacity to recognize target cells. When the modified virus

What is the difference between HSV 1 and 2? HSV-1 most often causes oral herpes and HSV-2 typically causes genital herpes. According to Plan Parenthood‚ HSV-1 (oral herpes) is present in more than half of American adults and 1 in 6 is infected with HSV-2 (genital herpes). Symptoms HSV-1: Lesions knowns as cold sores or fever blister are located on or near the mouth. Sometimes they can be found in the mouth and usually only happen the first time HSV-1 symptoms show up. Now‚ don’t confuse this with

A. Is a Virus Alive? 1. Viruses are segments of nucleic acids contained in a protein coat. 2. Pathogens are agents that cause disease. 3. Viruses do not grow‚ do not have homeostasis‚ and do not metabolize‚ therefore scientists don’t consider them to be living. 4. Discovery of Viruses i. Scientists filtered bacteria from the sap of infected plants‚ and were surprised to find that the filtered sap could still cause uninfected plants to become infected. ii. In 1935‚ Wendell Stanley of the Rockefeller

solutions to slow down the rise of resistance. Things that we can do are to not use antibiotics unnecessarily. This seems to be a huge problem. People tend to want to take antibiotics for colds and flu when in fact they do nothing for them as they are a virus. If you are prescribed antibiotics you should take them until the prescription is gone. If you start feeling better after a few days and discontinue taking the antibiotics the bacteria it was prescribed to fight is still present and starts to survive

Introduction-Chickenpox is a common childhood skin disease caused by a viral infection called varicella-zoster virus. Chickenpox is less common in the United States due to universal vaccination with the varicella virus vaccine‚ though it still occurs in populations that are not routinely vaccinated. The varicella-zoster virus is similar to herpes simplex virus in many respects. The virus is spread through air droplets or direct contact with active lesions. Most cases of chickenpox arise between the

2.2 Aetiological agent: Classification and characterisation The monkeypox virus is a member of the genus orthopox (family Poxviridae). Other members include cowpox‚ vaccinia‚ and variola (smallpox) viruses. Poxviruses are the largest vertebrate viruses known. The virions contain a linear double-stranded deoxyribonucleic acid (DNA) genome and enzymes that synthesise messenger ribonucleic acid (RNA). The viruses multiply in the cytoplasm of the host cells. The poxvirus family consists

nonliving? Scientist all over are debating whether or not a virus is in fact a living organism. There are many different opinions about this touchy topic from many different scientists. My job was to read through all of these different opinions and decided which side I agreed with. Do I think that viruses are living or nonliving? The answer to that question is‚ I absolutely believe viruses are nonliving and ill tell you why. Just because a virus seems alive doesn’t mean it is alive. After all‚ it’s

something that we need some of‚ it needs a warmth‚ moisture‚ time and food in order to multiply‚ which in the right conditions they multiply quickly. Viruses need a living host in order to survive‚ they don’t respond to antibiotics and new strains of virus are developing all the time. Fungi are moulds and yeasts‚ they need a warm and damp environment to survive‚ much like bacteria. Parasites feed off the host it’s inhabiting‚ it uses the nourishment from the flesh to survive. 2.
