Listeria Essays

The complete taxonomic hierarchy of Listeria monocytogenes is: Bacteria (Domain), Eubacteria (Kingdom), Firmicutes (Phylum), Bacilli (Class), Bacillales (Order), Listeriaceae (Family), Listeria (Genus), and Listeria monocytogenes (Species). L. monocytogenes is a gram-positive, rod-shaped bacteria. The rods of L. monocytogenes are often arranged into short chains, and in direct smears can appear coccoid and be mistaken for steptococci. Longer cells of L. monocytogenes can ressemble corynebacteria

Listeria Bacteria found in the Listeria genus are Gram-positive, flagellated, rod shaped bacteria found in several places. For instance, water, soil, and animals like cattle. The Listeria genus has the special and uncommon ability to survive and grow in severe environments, including freezing temperatures. The optimum temperature for Listeria to grow is 30 degrees to 37 degrees Celsius. (Holt, Krieg, Sneath, Staley, & Williams, 1994) These non-spore forming bacteria are also facultative anaerobes

disease which can be treated if it is diagnosed early. This infection is deadly for the elderly, the immune compromised and for pregnant women as it can cause the loss of their child or it can cause their child to suffer different disabilities. The listeria bacterium can be killed by cooking or pasteurization but not by refrigerating it. The incubation period of listeriosis is 3 to 70 days and the illness can last from days to weeks. Causes: It can be caused by the consumption of vegetables which have

Listeria monocytogenes is an important food-borne pathogen and is widely tested for in food, environmental and clinical samples. Given the close morphological and biochemical resemblances of L. monocytogenes to other Listeria species, and the non-specific clinical manifestations of listeriosis, the availability of rapid, specific and sensitive diagnostic tests capable of distinguishing L. monocytogenes from other (Liu, 2006). In the food industry, standard culture procedures are used as reference

The recent outbreak of food poisoning in South Africa that led to several deaths is Listeria(listeriosis). Listeriosis is an infection that is caused by consuming food contaminated by the bacteria Listeria. The infection can cause serious illness in pregnant women, neonates, adults with weakened or compromised immune systems and the elderly, and is capable of causing gastroenteritis in others who have been severely infected. Most people infected show no symptoms, but the elderly and very young are

2.6.1 Global epidemiology of Listeria monocytogens The illness Listeriosis is an advancing infection of major public health significance worldwide due to the occurrence of its foodborne outbreaks and significant risk of mortality and morbidity. According to Weinstein and Bronze (2015), the overall mortality rate of L monocytogenes infection is 20-30%. Human listeriosis is mainly acquired through ingestion of contaminated food; Other modes of transmission include the transmission of the infection

Blue Bell Creameries over listeria contamination issues. According to Entrepreneur.com and Wall Street Journal, three deaths were associated with the outbreak. Government authorities are trying to investigate the causes of such outbreak. In April, Blue Bell voluntarily subjected itself for investigation. On the same month, death cases in association with ice cream 's listeria were reported. Blue Bell Creameries closed down operations in April in Brenham, Texas over listeria contamination issues. The

Abstract Meat borne diseases associated with consumption of ready-to-eat meat contaminated with Listeria monocytogenes represents a considerable public health concern. The ability to persist in food-processing environments and multiply under refrigeration temperatures makes L. monocytogenes a serious threat to public health. L. monocytogenes contamination is one of the leading microbiological causes of food recalls. Ready-to-eat (RTE) cooked meat and meat products are frequently contaminated with

Detection of listeria spp Contamination of food and dairy products with Listeria is the major cause of foodborne disease in human. Since researchers have found out that listeria is a foodborne pathogen, there is a continuous challenge on isolation of bacteria from food and other samples [115]. The primary studies indicated that Listeria is able to grow at low temperature so researchers used this phenomenon for isolation of bacteria from clinical samples by culturing for a long time in 4oC but this

listeriosis? Listeriosis is a foodborne infection caused by a motile, rod-shaped, gram-positive, and food-borne bacteria called listeria commonly found in contaminated food (D, 2004). It is most likely to infect people who have a compromised immune system, pregnant women, older people, newborn, birds, and animals and it can give rise to meningitis and encephalitis. Listeria monocytogene discussion It is a foodborne pathogen which can infect both humans and animals. Structurally it is rod-shaped and

Meningitis Meningitis is a deadly disease. Meningitis is the disease where the protective membrane surrounding the brain and spinal cord has an inflammation. Meningitis is caused by a viral or bacterial infection. Meningitis can be quite painful to suffer through, although the treatment is not that complex, the affected human suffers a variety of the following symptoms: headache, nausea, vomiting, seizures, sleepiness or diffuclty waking up, no appetite or thirst, rash of purple discolouration fever

Bacillus circulans, Bacillus coagulans, Bacillus megaterium, Bacillus subtilis, Bacillus thuringiensis, Brevibacillus brevis, Geobacillus stereothermophilus, Lysinibacillus sphaericus, Clostridium perfringens, Corynebacterium pseudodiphtheriticum, Listeria monocytogenes, Lactobacillus casei, Enterococcus faecalis (Streptococcus), Streptococcus lactis (Lactococcus), Streptococcus mutans, Streptococcus pneumonia, Micrococcus (Kocuria) roseus, Sarcina lutea (Micrococcus luteus), Sporosarcina ureae, Staphylococcus

As a pet owner you have to supply your pet with a nutritionally balanced diet. Trying to figure out which dietary meal plan is best for your pet can be hard with so many commercial options on the market as well as many raw food diet regimens. Things to take into account when choosing an appropriate diet for your canine include: metabolic needs, growth stage, and activity level. During this essay I am going to analyze dry commercial dog food diets versus raw homemade and commercial diets. Using observation

foodborne illness, resulting in 128,000 hospitalization and 3000 deaths. Eight known pathogens account for the vast majority of those estimates. Those pathogens are Norovirus, Salmonella, Campylobacter, Clostridium perfringens, Escherichia coli, Listeria monocytogens, Staphylococcus aureus, Toxoplasma gondi. Norovirus is every contagious virus. You ca get the virus through an infected person, contaminated food or water. The virus causes your stomach and intestine to get inflamed. This leads to stomach

Principle is a set of rules people follow in order to have a disciplined and just society. A principle can be rules related to business such as GAAP (Generally Accepted Accounting Principles), where public traded companies are required to follow a strict set of standards to report annual financial reportings to investors. A repercussion in which we all recalled was the 1929 Great Depression when companies' financial figures were unregulated, and businesses could report fake numbers to attract investors
