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.
Fungal sepsis accounts for approximately 5% of severe sepsis and septic shock cases; the most common cause of fungal sepsis is an infection by Candida species of yeast, [29] a frequent hospital-acquired infection. The most common causes for parasitic sepsis are Plasmodium (which leads to malaria), Schistosoma and Echinococcus. The most common ...
There are four types of distributive shock. The most common, septic shock, is caused by an infection, most frequently by bacteria, but viruses, fungi and parasites have been implicated. [3] Infection sites most likely to lead to septic shock are chest, abdomen and genitourinary tract. [3]
By definition, septic abortion is caused by a variety of bacterial infections. Bacteria can come from vaginal and endocervical flora or can be transmitted sexually. [4] 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 ...
An overwhelming post-splenectomy infection (OPSI) is a rare but rapidly fatal infection occurring in individuals following removal (or permanent dysfunction) of the spleen. The infections are typically characterized by either meningitis or sepsis, and are caused by encapsulated organisms including Streptococcus pneumoniae. [3]

E.coli is the most common cause of community-acquired bacteremia accounting for approximately 75% of cases. [24] E.coli bacteremia is usually the result of a urinary tract infection. Other organisms that can cause community-acquired bacteremia include Pseudomonas aeruginosa, Klebsiella pneumoniae, and Proteus mirabilis.
One of the common microbes that can lead to widespread dissemination of septic emboli is Fusobacterium necrophorum, a Gram negative anaerobic bacillus. Fusobacteriota are commensal organisms in the oral cavity. F. necrophorum and F. nucleatum are the most important among the non-spore forming anaerobic bacilli in causing human infections.
