We have all heard of, and possibly have had at least once on our lives strep throat. Strep throat is a bacterial infection in the throat and the tonsils. The throat gets irritated and inflamed, causing a sudden, severe sore throat. Strep throat is caused by streptococcal (strep) bacteria. There are many different types of strep bacteria. Some cause more serious illness than others.

...whatsoever. Although healthy people can get invasive GAS disease, people with chronic illnesses like cancer, diabetes and kidney dialysis, and those who use medications such as steroids, are at higher risk.
Group A streptococcus bacteria can be treated with common, inexpensive antibiotics. Penicillin is the drug of choice for both mild and severe disease. In addition to antibiotics, supportive care in an intensive care unit and sometimes surgery are necessary with these diseases. Early treatment may reduce the risk of death although, unfortunately, even appropriate therapy does not prevent death in every case. The spread of all types of group A streptococcal infections may be reduced by good hand washing, especially after coughing and sneezing, before and after preparing foods and before eating.
As for my brother, he was very lucky and doing just fine now.
Sepsis is a problem of bacterial, parasitic and fungal infections. Due to this, the body develops a systemic immune response to get rid of the infection or tissue damage. This causes inflammation throughout the body, mainly found in small blood vessels or it leads to septicaemia which is where microbes or infections are found in the blood; this can also be called blood poisoning. Septic shock is a life-threatening condition where hypotension occurs as blood pressure drops to a dangerously low level after an infection. In septic shock the patient may experience tachyeordia, this is where there is a greater heart beat than normal (90 heart beats a minute) and tachypnae where the patient is breathing faster than the normal rate (12-20 breathes per minute).
Hypovolemic shock specifically disrupts the cardiovascular system from a significant loss of blood volume that causes blood pressure to deplete and oxygen delivery to cells to slow. A victim entering into hypovolemic shock will experience three sequential stages as the body attempts to maintain homeostasis. These stages are named compensated, decompensated, and irreversible (Wang
"Streptococcal pharyngitis," more commonly known as strep throat, usually appears suddenly with severe sore throat pain and is highly contagious. Immediate treatment is required and will cost $111 at an urgent care clinic and $531 at an ER.
It is not unusual for some healthy women to harbor Group B streptococcus bacteria in their rectum and vagina. These microorganisms do not usually cause disease when few in number, but when they grow in number and colonize these areas, bacterial infection can become severe.
Pertussis: Pertussis also known as whopping cough is a highly contagious bacterial disease that causes an uncontrollable, severe coughing. It is a serious disease that can affect individual of all ages with severe complication resulting in permanent disability in infants and lastly death. The fact that this 7-months old baby stay up night, inability to sleep can make it hard to breathe. Burns, Cotter, Harvill, Hewlett, Merkel, Stibitz & Quinn explained that pertussis is an upper respiratory infection caused by the Bordetella pertussis bacteria in addition to the systemic manifestations such as “lympocytosis, dysregulated secr...
My disease is Streptococcal pneumonia or pneumonia is caused by the pathogen Streptococcus pneumoniae. Streptococcus pneumoniae is present in human’s normal flora, which normally doesn’t cause any problems or diseases. Sometimes though when the numbers get too low it can cause diseases or upper respiratory tract problems or infections (Todar, 2008-2012). Pneumonia caused by this pathogen has four stages. The first one is where the lungs fill with fluid. The second stage causes neutrophils and red blood cells to come to the area which are attracted by the pathogen. The third stage has the neutrophils stuffed into the alveoli in the lungs causing little bacteria to be left over. The fourth stage of this disease the remaining residue in the lungs are take out by the macrophages. Aside from these steps pneumonia follows, if the disease should persist further, it can get into the blood causing a systemic reaction resulting in the whole body being affected (Ballough). Some signs and symptoms of this disease are, “fever, malaise, cough, pleuritic chest pain, purulent or blood-tinged sputum” (Henry, 2013). Streptococcal pneumonia is spread through person-to-person contact through aerosol droplets affecting the respiratory tract causing it to get into the human body (Henry, 2013).

(Nemours, 1995-2011) The two main bacteria precipitating Impetigo are staphylococcus aureus, the most common cause, and streptococcus pyogenes. If left untreated, streptococcus pyogenes can also cause post-streptococcal glumerulonephritis, or a disease that causes inflammation of the kidney to occur following a strep throat infection. Although this is rare, standard precautions must still be taken to prevent these repercussions. Staphylococcus aureus and streptococcus pyogenes are the main causes of impetigo, but they are not the only.
An outcome of World War I was a new medical disorder classified as Shell Shock. Shell Shock is a medical disorder developed to describe the symptoms that soldiers developed without a probable or obvious lesion as the cause after serving time on the war front. Shell Shock is one of the most prominent injuries of World War I; the symptoms varied among each soldier, treatments were still being developed, and doctors were still trying to understand the severity of the disorder. The symptoms soldiers described are due to the stress they encountered while they served on the front line. Shell Shock is a condition that soldiers have begun to develop after serving in the war.
