Why does bacteremia (blood stream infections) cause fever and shock?
469109
In short, bacteremic septic shock can be caused by a variety of bacterial cell components.  For gram negative bacteria, endotoxins, formyl peptides, and exotoxins are among components of the cell that can elicit such a response.  In gram positives, enterotoxins, peptidoglycans, and most especially superantigens (SPEs) will act in the same manner.  These cell components super-activate our cell-mediated immune system cascade, causing mass release of cytokines.  Cytokines are inflammatory mediators, and are ultimately responsible for the fever and septic shock effects seen.

Red blood cell: The blood cell that carries oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cell its red color (and name). \nThe mature red blood cell (RBC) is a non-nucleated biconcave disk. Thanks to this unusual shape and its hemoglobin content, the RBC is superbly suited to the transport of oxygen. \nA red blood cell is sometimes simply referred to as a red cell. It is also called an erythrocyte or, rarely today, a red blood corpuscle.\n\nWhite blood cell: One of the cells the body makes to help fight infections. There are several types of white blood cells (leukocytes). The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, PMNs, or "polys"). \n\nLymphocytes are made in lymphoid tissue in the spleen, lymph nodes, and thymus gland. There are different kinds of lymphocytes. Lymphocytes identify foreign substances from germs (bacteria or viruses) in the body and produce antibodies and cells that specifically target them. It takes from several days to weeks for lymphocytes to recognize and attack a new foreign substance. \n\nNeutrophils are also major players in the body's defense against bacterial infections. Neutrophils are made in the bone marrow and circulate in the bloodstream. Neutrophils move out of the blood vessels into the infected tissue to attack the bacteria. The pus in a boil (an abscess) is made up largely of neutrophils. Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher than normal white blood cell count (WBC). When the WBC is low, there may not be enough neutrophils to defend against bacterial infections. \n\nThe white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis. \n\nA normal absolute neutrophil count (ANC) is in the range of 1,500 to 8,000 cells per microliter. If the ANC is below 500 for an extended period of time, the risk of serious bacterial infection may increase significantly. A low neutrophil count is called neutropenia.

you will see an increased number of proteins in the instances of viral infections (meningitis) and certain disease states (multiple sclerosis). RBC's are increased if trauma occurs, such as a subarachnoid hemorrhage or other spinal cord damage. another instance would be if the physician performing the lumbar puncture wasn't very experienced...they will get a blood-contaminated specimen.

Fever (also known as pyrexia, or a febrile response, and archaically known as ague) is a medical symptom that describes an increase in internal body temperature to levels that are above normal (37°C, 98.6°F). A fever is most accurately characterized as a temporary elevation in the body’s thermoregulatory set-point, which is usually by about 1-2°C. This elevation in thermoregulatory set-point means that the previous "normal body temperature" would be considered hypothermic. Effector mechanisms, such as increased blood pressure, increased heart rate, activation of brown adipose tissue, and muscular shivering attempt to counteract the perceived hypothermia, thereby reaching the new thermoregulatory set-point. It is the most common symptom of many diseases.\n\n\nSo now in simple word as the temperature of our body goes high our body start to react and water form the eyes is one of the effects.

IT could be an infection of some type. There are also diseases that cause fevers, such as lupus. Also it could be the heat. I know in the summer time I run a low grade fever, it's pretty normal for me. I did talk to a doctor about it. \n\nSeeing a doctor is advisable. ;0)

There are several reasons body temperature can change quickly.  Hormonal upsets like hot flashes, lupus, illness/virus/infection/fever, thyroid malfunction all are causes.  Weather and exercise can also change temperature in the body.  Heatstroke and shock and make temperatures drop too.\n\nI would say, and I'm not a doctor, that you need to have a physical with a complete blood workup to test for thyroid, white blood count, lupus, and then go from there to see what the doctor thinks.

It sounds like a pseudomonas infection caused by the pseudomonas aeruginosa bacterium.\n\nOrdinarily this isn't a cause for concern as the body's natural defense mechanism will combat it but in people with a weakened immune system it can cause infection and varying symptoms.\n\nThere's an article written by a doctor here... http://www.healthline.com/gale/Medicine/Pseudomonas-Infections/gem_04_01295.html which gives more info of the cuases, symptoms etc

An infection starts in another area and if it goes untreated or treated with the wrong antibioitic or depending where the infection is it can seep into the blood stream.  Say you have deep cut that you thought was nothing and ignored it.  Bacteria could enter the cut and cause an infection.  The infection can get so deep into the skin that it could go into the blood stream or the bone (called osteomylitis).  I have seen kids get a positive blood culute from an ear infection, urinary tract infection, and even a sore on the bottom of the foot.  Bottom line, keep cuts clean, take all your antibiotics if a doctor prescribes it and call the doctor for fevers, redness, swelling or increased pain.  All signs an infection can be present.  Hope your friend it is better.

Toxic shock syndrome (TSS) is an uncommon but potentially serious illness that occurs when poisonous substances (toxins) produced by certain bacteria enter the bloodstream. The toxins cause a type of blood poisoning caused by staphylococcal, or less commonly streptococcal, infections in the lungs, throat, skin or bone, or from injuries. Women using super-absorbent tampons during menstruation were found to be most likely to get toxic shock syndrome.

The plage fever starts due to the Yersinia pestis bacteria and this bacteria was responsible for the wide spread bubonic and septicemic plague which took away lives of thousands of people. \n\nThe plague fever started with a headache. Then chills and fever, which left him exhausted and prostrate. Maybe he experienced nausea, vomiting, back pain, soreness in his arms and legs. Perhaps bright light was too bright to stand.\n\nWithin a day or two, the swellings appeared. They were hard, painful, burning lumps on his neck, under his arms, on his inner thighs. Soon they turned black, split open, and began to ooze pus and blood. They may have grown to the size of an orange.\n\nMaybe he recovered. It was possible to recover. But more than likely, death would come quickly. Yet... perhaps not quickly enough. Because after the lumps appeared he would start to bleed internally. There would be blood in his urine, blood in his stool, and blood puddling under his skin, resulting in black boils and spots all over his body. \n\nEverything that came out of his body smelled utterly revolting. He would suffer great pain before he breathed his last. And he would die barely a week after he first contracted the disease.\n\nThe swellings, called buboes, were the victim's lymph nodes, and they gave the Bubonic Plague its name. But the bubonic form of the disease was only one manifestation of the horrible pandemic that swept Europe in the 1340s. Another form was Pneumonic Plague. The victims of Pneumonic Plague had no buboes, but they suffered severe chest pains, sweated heavily, and coughed up blood. Virtually no one survived the pneumonic form.\n\nThe third manifestation was Septicemic Plague. This sickness would befall when the contagion poisoned the victim's bloodstream. Victims of Septicemic Plague died the most swiftly, often before any notable symptoms had a chance to develop. Another form, Enteric Plague, attacked the victim's digestive system, but it too killed the patient too swiftly for diagnosis of any kind.\n\nMedieval Europeans had no way of knowing any of this. The causes of plague were not discovered until the late nineteenth century.\n\nPlague is carried by rodents like rats and squirrels, but it is transmitted to humans by the fleas who live on them. A flea, having ingested plague-infected blood from its host, can live for as much as a month away from that host before he needs to find another warm body to live on. When a blood-engorged flea attempts to draw blood from another victim, it invariably injects into that victim some of the blood already within it. If the injected blood contains the bacterium yersinia pestis, the result is Bubonic Plague. Fleas were, alas, such a part of everyday life that no one noticed them much. In this invisible manner the plague spread from rat to human and to cat and dog, as well.\n\nPneumonic plague is airborne. It is contracted by breathing the infected water droplets breathed (or coughed) out by a victim of the disease. The pneumonic form was much more virulent and spread much more quickly and just as invisibly.\n\nPlague is occasionally transmitted by direct contact with a carrier through open sores or cuts, directly into the bloodstream. This could result in any form of the plague except pneumonic, although it is likely that such incidents most often resulted in the septicemic variety. The septicemic and enteric forms of the plague killed most quickly of all, and probably accounted for the stories of individuals going to bed apparently healthy and never waking up.\n\nPeople died so swiftly and in such high numbers that burial pits were dug, filled to overflowing and abandoned; bodies (sometimes still living) were shut up in houses which were then burned to the ground; and corpses were left where they died in the streets.

Cotton fever is probably not caused by cotton fibers. It's more likely caused by bacteria that live in the cotton. Cotton can grow a lot of bacteria, especially after it gets wet. Re-using cottons can put bacteria directly into your blood stream. Cotton fever is uncomfortable, but it's usually not serious.\n\nSymptoms may include:\n Chills\n Headaches\n Fever\n Nausea \n Hot flashes\n Vomiting \n Shaking that you can't control  \n Shortness of breath
