Listeria is a bacterium with many subspecies Biology essay
Listeria monocytogenes. Listeria monocytogenes was first described by H lphers from the necrotic liver of a rabbit in Sweden and was named Bacillus hepatis Carvalho, Sousa amp. In research, H Murray isolated a similar bacterium as the cause of an epizootic in rabbits and guinea pigs. Listeria monocytogenes was discovered during an epidemic that affected rabbits and guinea pigs. It was later shown to infect wild animals and humans and was recognized as a food pathogen. This bacterial pathogen is responsible for gastroenteritis in healthy individuals, meningitis in immunocompromised individuals, and a biology essay is a technical piece of assignment that requires careful topic selection, structure, and writing. So if your teacher hasn't given you a title for the essay, you should proceed carefully when choosing topics. In this post, we share a list of biology-related ideas that you may find useful and equally interesting. The harmful and potentially deadly bacterium Listeria is extremely good at adapting to change. Research now shows exactly how cunning Listeria is and why it is so difficult to combat. The discovery. Listeria is likely to sicken pregnant people and newborns, adults or the elderly, and people with weakened immune systems. Other people can be infected with Listeria, but that rarely happens. Listeria monocytogenes is a foodborne pathogen that causes listeriosis, a group of human diseases that is more common in countries with better developed food supply systems. This review discusses the efficacy of actual biocontrol methods in combination with the major food types implicated in disease. Comments on, Chills. Muscle strain. Nausea. Diarrhea. Symptoms may begin a few days after you eat contaminated food, but it may also take days or longer for the first signs and symptoms of infection to begin. If the listeria infection spreads to your nervous system, signs and symptoms may include: Headache. Stiff neck. Loss of balance or difficulty walking. convulsions or fits. fever. muscle strain. People with invasive listeriosis often do not experience the first symptoms until weeks after exposure. 2. Epidemiology. L. monocytogenes is considered a widespread bacterium in nature, as it is part of the fecal flora of many mammals and is a common food source. It is believed that the main route of bacterial transmission occurs through the consumption of contaminated food, such as meat sausages, pate, ham, salami and abstract and figures. Listeria monocytogenes is a ubiquitous gram ve, rod-shaped, facultative and motile bacterium. It has become an opportunistic intracellular pathogenic microorganism. To be on the safe side, always wash all vegetables thoroughly, according to the CDC. Use these steps: • Wash your tray with soapy water for a few seconds, both before and after handling leafy greens. • Do not let the greenery soak in it. Listeria monocytogenes is a gram-positive, facultative intracellular rod bacterium that is catalase positive and beta-hemolytic when grown on blood agar. There have been several foodborne illnesses in the past involving L. monocytogenes. It was revealed that L. monocytogenes is a foodborne illness associated with a variety of foods. In, 1. Introduction. Listeria monocytogenes, a member of the genus Listeria, occurs naturally in agricultural environments such as soil, manure and water. The ability of this microorganism is often mentioned in scientific literature,,
