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.
10 to 80% risk of death; [4] [6] These mortality rates (they are for a range of conditions along a spectrum: sepsis, severe sepsis, and septic shock) may be lower if treated aggressively and early, depending on the organism and disease, the patient's previous health, and the abilities of the treatment location and its staff: Frequency
Gram positive bacteria are an increasingly important cause of bacteremia. [13] Staphylococcus, streptococcus, and enterococcus species are the most important and most common species of gram-positive bacteria that can enter the bloodstream. These bacteria are normally found on the skin or in the gastrointestinal tract. [citation needed]
A Gram stain is performed to show Gram-positive cocci in chains. Then, the organism is cultured on blood agar. The rapid pyrrolidonyl arylamidase (PYR) test is commonly used, wherein a positive reaction confers a presumptive identification of group A beta-hemolytic streptococci if the appearance and clinical context is consistent.
Melioidosis is an infectious disease caused by a gram-negative bacterium called Burkholderia pseudomallei. [1] Most people exposed to B. pseudomallei experience no symptoms; however, those who do experience symptoms have signs and symptoms that range from mild, such as fever and skin changes, to severe with pneumonia, abscesses, and septic shock that could cause death. [1]
The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall structures and do not take up Gram stain in the same manner as gram-negative and gram-positive ...

Gas gangrene can cause myonecrosis (muscle tissue death), gas production, and sepsis. Progression to toxemia and shock is often very rapid.
If the infection is not eradicated and managed, it can lead to septic shock and acute respiratory distress syndrome (ARDS). [28] In severe cases, women with high fever, pelvis peritonitis , and tachycardia should be hospitalized for a course of antibiotic and evacuation of the remaining pregnancy tissue.
