Hepatitis B Virus Characteristics: Hepatitis B Virus (HBV) is a double-stranded DNA virus in the Hepadnaviridae family. The infectious particle is 42nm in diameter, with a genome 3200 nucleotides long. It has an outer envelope and an icosahedral nucleocapsid, which contains viral DNA polymerase and has a diameter of 27nm. The envelope contains the HBV surface antigen (HBsAg); this is the molecule to which anti-HBV antibodies are directed. The non-infectious hepatitis B particles are composed
HEPATITIS B VIRUS Hepatitis B Virus (HBV) is a virus that attacks the liver. The virus is transmitted through blood and bodily fluids. This can occur through direct blood-to-blood contact, unprotected sex, use of contaminated needles, and from an effected mother to her newborn during the delivery process. The majority of people do not have noticeable symptoms when they are first infected with the HBV. People who do not know they are infected with the HBV, their body can respond in different ways
Hepatitis B virus (HBV) is a severe and common virus that has infected ‘more than two billion people alive today at some point in their life.’1 It is a hepadanavirus that interferes with the liver functions as it replicates in the hepatocytes (liver cells) and induces a immune response that is responsible for the inflammation of liver.2 Viruses are not motile, which means that HBV is also sessile and does not form spores. The spherical virion, is called a Dane Particle3 that is 42nm in diameter binds
Hepatitis B virus can cause an infection either in the form of a short, acute illness or a chronic, long-lasting condition that affects the liver. Hepatitis B can cause serious disease in infants, so pregnant mothers who carry the virus must try to protect their babies by being screened and having their babies vaccinated after birth. What Is Hepatitis B? Hepatitis B virus is an organism that infects the liver, causing either a short, acute illness or a chronic, long-lasting disease. A baby who gets
Hepatitis B Hepatitis B is a disease of the liver caused by the virus HBV. Known as serum hepatitis or “the silent infection", it could cause liver cirrhosis or liver cancer. Hepatitis B can be as severe as a minor illness enduring a few weeks to a serious, lifetime disease. Hepatitis B is commonly contracted through blood, semen, or other body fluids from an individual infected with the Hepatitis B virus into the body of someone who is not infected by Hepatitis B. Infection of the Hepatitis B can
AIDS or hepatitis B virus is likely. Many people do not know that there has never been an actual reported case of contracting AIDS while getting a tattoo. This is because the amount of blood needed to contract the AIDS virus is about two drops, which is incomparable to the amount of blood on a non-sterilized needle. So, basically the odds of contracting AIDS is one in every two hundred cases of accidental sticking with a non-sterilized needle. One is more susceptible to the hepatitis B virus, because
Hepatitis Hepatitis means inflammation of the liver. Many illnesses and conditions can cause inflammation of the liver, for example, drugs, alcohol, chemicals, and autoimmune diseases. Many viruses, for example, the virus of Mononucleosis (Mono) and the Cytomegalovirus can inflame the liver. The effects that hepatitis has on the liver is very similar to the effects of alcohol causes, this virus is the leading cause of liver cancer and the common reason for liver transplants. Liver disease has
Hepatitis B Hepatitis B virus (HBV) belongs to the Hepadnarvirus family. The virus particles consist of a lipid envelope that contains surface antigens, HBsAg, a core made of proteins, viral DNA, and polymerase. Theses virions are approximately forty nm in diameter, which are known as one of the smallest enveloped animal viruses. It infects hepatocytes, also known as Dana particles. The genome of HBV is circular, partly double stranded, and approximately 3,200 nucleotides long. Dr. Baruch Blumberd
Conor Moldowan Micro 5 Fall 2014 Robert Cattolica Hepatitis C Virus Hepatitis is a word that describes an inflammation of the liver. According to Evelyn Strauss, who has a Ph.D. in biochemistry, this progresses to scarring of the liver tissue. The scarring of the liver tissue causes decreased functionality of the liver, cancer, and possibly death. Many people were afflicted with hepatitis in the past ("2000 Albert Lasker Award for Clinical Medical Research"). Additionally Evelyn Strauss says that
Hepatitis B is a virus that attacks the liver. It can lay dormant for years with little to no symptoms or you can start having symptoms in as little as a few weeks. It can not only affect the liver, but also the oral cavity as well. Appearing anywhere from one to four months, signs and symptoms of Hepatitis B can occur. Signs and symptoms range from mild (intolerance to alcohol, dark urine, nausea and vomiting, and weakness and fatigue) to severe (loss of appetite, jaundice, abdominal pain, and
A virus is a submicroscopic parasitic organism that feeds on cells. Viruses are dependent on cells for their nutrients so the virus survive and reproduce. Every virus consists of either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). A virus can contain a strand of one or the other, but not both. This RNA or DNA is contained within a protein shell for protection. A virus is a parasite that is dependent upon cells for metabolic and reproductive requirements. By using the cell the virus makes
Hepatitis is the inflammation or swelling of the liver. The inflammation can happen from different injuries or viral forms of a disease. People who experience hepatitis have the symptoms of malaise, nausea, vomiting, loss of appetite, fever and jaundice. There are six known forms of Hepatitis which are Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E and Hepatitis G. The presence of hepatitis in the body can be very risky and cause severe death if not taken care of. Hepatitis is a
HBV:- Hepatitis B virus is a pathogen which causes disease hepatitis B. It infects liver of hominoidae which includes humans resulting in inflammation which causes hepatitis. It was originally called as serum hepatitis which have epidemics in Asia and Africa. It is also endemic in some parts of China. Above than two billion people is infected by hepatitis B virus. It included three hundred and fifty million chronic patients of virus. HBV is transmitted through body fluids or by infectious blood.
Brief description and explanation of disorder: Hepatitis B is an infection of ones liver which prevents it from working well. The infection can also cause scarring of the organ. It can cause cancer and liver failure if not treated right away. The good news about this disorder is that in most cases, the disorder does not last very long. Once your body fights off the disease, you become immune to it for the rest of your life. Hepatitis b is a DNA virus. It is caused when people come in contact with
Introduction Hepatitis B, an infectious disease caused by the Hepatitis B virus (HBV, a DNA virus), was formerly called serum hepatitis, inoculation hepatitis and post-transfusion hepatitis. Infection with HBV may result in acute, fulminant or chronic hepatitis, sometimes even resulting in a chronic asymptomatic carrier state, apart from hepatocellular carcinoma and liver cirrhosis (Davis 179). The disease is transmitted when an individual comes in contact with infected blood or objects. It may
1 Hepatitis B 1.1 Hepatitis B virus Hepatitis B (HBV) is a blood-borne viral liver infection with various routs of transmission. It is one of the most common and serious liver diseases in the world and a leading cause of death worldwide. If the infection becomes chronic the infection can lead to liver failure, cirrhosis and hepatocellular carcinoma. The HBV virus is transmitted through contact with contaminated blood or other body fluids such as serum, semen and salvia. The condition following the
Introduction Hepatitis A is a virus or an infection that causes liver disease and inflammation of the liver. According to Centers for Disease and Prevention, hepatitis A is a self- limited disease that does not cause a chronic infection and it is rarely fatal. The virus is an infectious disease of the liver which cannot be transmitted by sneezing and coughing. It is usually transmitted from person to person through the feces or the mouth, from consuming contaminated food or water. Many people
Hepatitis Hepatitis In modern society when a person gets sick with the flu or a cold they will usually go about their normal routine with the exception of a sneeze or a cough throughout the day. Sometimes things can be more than what they appear to be. The symptoms start out like the flu with coughing, fever, aches, and vomiting. However, the disease gradually worsens with symptoms of extreme weakness and excruciating abdominal pain. By then it is usually too late when the person finds out that
Opening: Hepatitis B is a viral liver disease that can cause mild to severe illness. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. Body: Hepatitis B is a contagious liver infection caused by the hepatitis B virus. Hepatitis B can be acute or chronic. Every type of hepatitis can increase your risk of liver scarring and liver failure. Hepatitis B infection may be either acute (short-lived) or chronic (long lasting): • Acute
3.3.2.2. Hepatitis This is the inflammation of the liver. The hepatitis virus is a major cause of hepatitis in humans. However, the condition can be induced by various infections and medical conditions, such as excess intake of alcohol, medications, toxins, and autoimmune disease. There are five types of hepatitis virus which include: hepatitis A, hepatitis B, hepatitis C, hepatitis D, hepatitis E.
