Download file to see previous pages In contrast, prokaryotic cells are considered more primitive, and most bacteria are prokaryotic. These cells contain no organelles, and their DNA is loose in the cell rather than enclosed in a nucleus, and there is generally less than in eukaryotic cells (Levinson, 2006).
These distinctions are important in terms of controlling and understanding the behavior of microbes, especially in terms of containment of disease, vaccines and treatments. Bacteria tend to be prokaryotic cells. They have a range of different shapes, with some being shaped as rods, some as spirals and others circular. In addition, the cell walls of bacteria differ between gram-positive and gram-negative. The terms refer to how the cell walls are structured, in particular the size of the peptidoglycan layer, but also to a form of staining known as gram-staining which is used to differentiate between the two types of wall structure. The shape of bacteria as well as the type of cell wall allows different bacteria to be identified by looking at them microscopically. Bacteria are generally treated using antibiotics; these attack the cell walls of bacteria. As these are very different than our own cell walls, it is easy to make drugs that differentiate between the cells of the bacteria and the host cells (Levinson, 2006).
In contrast, viruses are often considered to be non-living. They share many of the characteristics of living cells, such as reproduction, nutrition and movement; however they lack respiration, making them difficult to define as either living or non-living. Unlike bacteria or other cell, viruses contain only DNA or RNA, they do not contain both. Viruses have an unusual form of pathology. Once present in the host’s system, they invade the cells of the host, using the machinery of the cell to replicate themselves. When they have replicated sufficiently, the new viruses burst out of the host cell and move to infect other cells. Because of this ...Download file to see next pagesRead More

Medical Microbiology American Blastomycosis

...., 2012). However, this method may take some time since growth of the organism is slow. In fact, growth may be observed as early as 5 days to as late as 30 days in some cases (Varkey and Raugi, 2011). Treatment The treatment for blastomycosis, regardless of its type, is entirely medical (Longo et al., 2012). For blastomycosis, anti-fungal agents are given to patients but the choice of which anti- fungal to use is based on the clinical form of the disease, immune status of the patient, and severity of the infection (Longo et al., 2012). In general, agents such as Ketoconazole, Itraconazole, Amphotericin B, and Fluconazole can be used for the treatment of Blastomycosis. However, Itraconazole, given for 6 months, is the drug of choice...

Zoonoses (Medical Microbiology)

... and Simpson (1998), this zoonotic disease is also more dangerous to pregnant woman because when a pregnant woman is affected, the child can also be infected thus leading to various health complications to the child. Other zoonotic infections such as trichinosis get to a person if they consume animal products especially from pigs such as hum, sausages etc which are infected with the eggs of trichinella. Trichinosis, according to Acha and Szyfres (2001), is however treatable using medications but has to be treated as early as possible to avoid irrevocable damage. Some zoonotic diseases such as Acquired Immunodeficiency Syndrome (AIDS), although it was first transferred from non human primates are now mainly transferred from one human...

Medical microbiology

(ii) The most commonly used stain for the gastric biopsy for the detection of H. pylori is the modified giemsa stain. Sections of the biopsy in a patient with gastritis would show epithelial damage and a generalized decrease in the thickness of the mucus layer. Eroded areas of the stomach lining would also show the presence of white blood cells such as lymphocytes and neutrophils. A haematoxylin and eosin stain of a person with chronic gastritis would show polymorphonuclear leucocytes intruding into the lining of the mucus gland. Helicobacter pylori resides deep into the lining of the stomach wall, and as the polymorphonuclear cell cannot easily reach the site of infection, they release superoxide radicals which damages the stomac...

Medical Microbiology and Immunology

...Topic: Medical Microbiology and Immunology Affiliation: Infection diseases are myriad, diverse, and dynamic from time to time. These results from their respective causal agents that vary across the numerous infection diseases that exist or those that emerge over time. In this respect, Zoonoses are common and reported cases keep emerging across both existing and emerging infections. In the U.K, campylobacteriosis has emerged and become a significant health issue that the relevant agencies must address. Topic 1 Campylobacteriosis is caused by Campylobacter jejuni bacteria (DuPont, 2011, p.291). The figures below show these bacteria: The bacteria are found in contaminated animal food products or in infected persons...

Medical Microbiology case study

...Medical Microbiology Case Study All about the case study The case study is an example of a health care associated infection which is an infection acquired in hospital. The type of infection in the case study is a urinary tract infection (UTI) which is the occurrence of pathogens at any point in the urinary tract (Tadesse & Alem, 2006). The defence mechanisms of the urinary tract include surface bladder muscosa, secretary IgA, menstrual flow in females, normal microbial flora and surface bladder mucosa (Tadesse & Alem, 2006). The causative agents of UTI are gram- negative rods like proteus spp, klesbsiella pneumonia, Escherichia coli, pseudomonas aeruginosa and enterobacter arogens (Tadesse & Alem, 2006). The infection routes of pathogens...
