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.
These antimicrobials should be directed at the eradication of Gram-negative aerobic organisms (i.e. Enterobacteriaceae, Pseudomonas ) that account for more than three-fourths of the isolates causing sepsis. Because aerobic and facultative Gram-positive bacteria (mostly alpha-hemolytic streptococci) cause sepsis in about a quarter of the victims ...
Sepsis caused by gram-negative bacteria is thought to be largely due to a response by the host to the lipid A component of lipopolysaccharide, also called endotoxin. [33] [34] Sepsis caused by gram-positive bacteria may result from an immunological response to cell wall lipoteichoic acid. [35]
Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature (e.g. fresh water, salt water, or soil). It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients.
[21] [22] In general, gram negative bacteria enter the bloodstream from infections in the respiratory tract, genitourinary tract, gastrointestinal tract, or hepatobiliary system. Gram-negative bacteremia occurs more frequently in elderly populations (65 years or older) and is associated with higher morbidity and mortality in this population. [23]
As with any gram-negative bacterium, N. meningitidis can infect a variety of sites. [citation needed] Meningococcal pneumonia can appear during influenza pandemics and in military camps. This is a multilobar, rapidly evolving pneumonia, sometimes associated with septic shock. With prompt treatment, the prognosis is excellent. [9]
Sepsivac is a drug developed by Cadila Pharmaceuticals to treat gram-negative sepsis. The active ingredient is heat-killed Mycobacterium w, a non-pathogenic strain of Mycobacterium . As an immunomodulatory , it modulates the immune system of the body and hence significantly reduces mortality rate in patients with gram negative sepsis.
GBS urinary tract infections, more than 100.000 CFU (colony forming units) /mL, may induce labour in pregnant women and cause premature delivery (preterm birth) and miscarriage and requires antibiotic treatment. The presence of GBS in the urine in any colony count is a marker of heavy GBS colonization and an indication for Intrapartum ...
