Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
The development of sepsis is primarily due to two scenarios. When there is an incomplete abortion caused by the pathogens that result in products of conception remaining in the body. The second scenario occurs intentional septic procedures leads to the spread of the infection from the placenta or fetus to the uterus; this can subsequently cause ...
Bacteremia can have several important health consequences. Immune responses to the bacteria can cause sepsis and septic shock, which, particularly if severe sepsis and then septic shock occurs, have high mortality rates, especially if not treated quickly (though, if treated early, currently mild sepsis can usually be dealt with successfully).

The sepsis type of infection is much more deadly, and results in a severe blood poisoning called meningococcal sepsis that affects the entire body. In this case, bacterial toxins rupture blood vessels and can rapidly shut down vital organs.
Human bite infections often contain Eikenella spp. and animal bites harbor Pasteurella multocida in addition to oral flora. Anaerobes infections are often polymicrobial in nature, and sometimes (i.e. decubitus ulcers, diabetic foot ulcer) they are complicated by bacteremia and/or osteomyelitis. [ 41 ]
The body has defence mechanisms that enable it to resist microbial invasion of its tissues and give it a natural immunity or innate resistance against many microorganisms. Pathogenic bacteria are specially adapted and endowed with mechanisms for overcoming the normal body defences, and can invade parts of the body, such as the blood, where ...
Overwhelming post-splenectomy sepsis (OPSS) [1] Specialty: Infectious disease: Usual onset: 24–48 hours following presentation with mild viral symptoms [2] Causes: Exposure to pathogens following splenectomy or asplenia: Risk factors: Splenectomy in the past 2–3 years, removal of spleen for hematological reasons, being under the age of 2 [2 ...
Humans can be infected with many types of pathogens, including prions, viruses, bacteria, and fungi, causing symptoms like sneezing, coughing, fever, vomiting, and potentially lethal organ failure. While some symptoms are caused by the pathogenic infection, others are caused by the immune system's efforts to kill the pathogen, such as ...
