Inflammation is the main type of innate immunity our body uses against A. schmiddy. Inflammation begins by activating acute-phase proteins, and soon after vasodilation occurs, followed by redness, swelling, pain, and heat. Once vasodilation occurs, histamine and kinins are released and blood vessels permeability is increased, causing white blood cells to report to the infected area. One problem associated with inflammation is that the capsule of A. schmiddy is an important virulence factor, which helps the bacteria to resists phagocytosis. Because the phagocytes cannot destroy the bacteria cells, infection further continues and necrotic tissue forms.
can hydrolyze urea into ammonia and carbon dioxide, and therefore raise urinary pH. Alkalinization of urine promotes precipitation of magnesium-ammonium phosphate salts leading to the formation of struvite stones, which may serve as a nidus for the persistence of infection or may directly obstruct the urinary tract, there by promoting infection. Proteus is often the cause of bacterial invasion of the bloodstream often associated with diabetes, heart and lung disease, or cancer. Proteus is regarded to be an undesired element of intestinal microflora, as the bacteria may also become a causative agent of diarrhea. Approximately 95% of UTIs occur when bacteria ascend through the urethra and the bladder.
Discussion Post Week ten NURS 6501, N-21 Urinary tract infections (UTIs) are usually caused by bacteria and are common. Symptoms of both upper and lower infections are similar; therefore, it is important for advanced practice nurses (APNs) to be able to determine the pathophysiology of upper and lower UTIs. The purpose of this discussion is to evaluate the similarities and differences between upper and lower UTIs, clinical manifestations, treatments, and factors affecting all of these things. UTIs are infections that may occur anywhere in the urinary tract such as the urethra, bladder, ureters, and kidneys. Typically UTIs are caused by bacteria from the gut flora and are inflammation of the urinary epithelium.
Broad spectrum antibiotics tend to kill the bodies normal flora, which then allows bacterium’s like C. difficile to spread and grow rapidly in its vegetative state. Toxin A (enterotoxin) is then produced causing diarrhea, followed by toxin B (cytotoxin) which causes damage to the mucosal cells. Toxin A and B also induce the secretion of cytokines into host cells, which often cause an acute neutrophilic inflammatory infiltrate. Together, these toxins enable the interruption of tight junctions in the intestine and cause inflammation of the colon leading to an extensive amount of fluid secretion (diarrhea). A third toxin has recently been discovered in newer strains of this bacterium called the binary toxin.
This includes increased concentrations of heavy metals such as Mercury (Hg) and Lead (Pb) found in the liver tissue and/or chemical toxins such as man-made Polychlorinated biphenyls (PCBs) and dichlorodiphenyltrichloroethane (e.g. DDTs) and these are found in the blubber tissue of cetaceans. (Pierce et al. 2008; Jepson et al. 1999): To investigate the high proportion of Harbour porpoises dying from infectious disease, chemical sampling was undertaken in the liver/blubber tissue of the strandings to research the effects of PCBs earlier mentioned as well as heavy metals like Mercury (Hb).
Gram-negative bacteria contain a layer of lipopolysaccharide (LPS) When the bacteria enters the body, the LPS triggers the body’s immune response. The body recognises a cytokine reaction from the bacteria which is toxic to the body and responds by inflaming the tissues and blood vessels. The certain cells used against the bacteria Bordetella Pertussis include innate and specific defenses, but the defensive antigens have not been exclusively identified. Explain how the disease can be treated. Pertussis is generally treated with antibiotics and it is vital to use the antibiotics early on in the infection or it will have little to no effect.
However, it could have serious consequences occur if spread inflammation of the urinary tract and kidneys. In my report I will talk about: • Definition • Symptoms • Causes • Risk factors • Prevention Definition: According to Mayo Clinic, a urinary tract infection generally develops when bacteria enter the urinary tract and begin multiplying. The most common urinary tract infections
This organ plays a vital role in homeostasis. Compromising the skin can lead to infection due to the body having no barrier against pathogens. Bacteria can enter the blood stream directly through the network of capillaries no longer protected by the skin. The body also has issues with monitoring temperature if a large area of skin is burned. Another major concern is the body not being able to regulate blood pressure due to the permeability of the
leprae, will not develop full-blown leprosy, as our immune systems are strong enough to fight off the bacteria. People who are infected and develop the disease are likely to have genes which make them susceptible to the infection. After infection however, it is important to receive treatment as soon as possible in order to kill the bacteria disease and avoid other complications which may occur if left untreated – such as blindness, disfiguration of the face, erectile dysfunction, kidney failure, permanent damage to the inside of the nose and nerves outside the brain and spinal
4. The discovery of what causes a disease was made by Louis Pasteur. Pasteur developed the Germ Theory, this states that a microorganism called the “Germ” can cause dangerous diseases. He discovered the germ in a food conversion, the germ was infecting the food and beverages causing people to get
