Gram-negative bacteria infections caused

Endotoxins are the lipopolysaccharides (LPS) of the outer membrane of Gram-negative bacteria. They trigger inflammatory reactions in the infected organism, activate complement and cause fever or even a septic shock. They act on toll-like receptors.

The answer is e. (Hardman, pp 1092-10945 Cefoxitin and cefmeta-zole are suitable for treating intraabdominal infections. Such infections are caused by mixtures of aerobic and anaerobic Gram-negative bacteria like B. fragilis. Cefoxitin alone has been shown to be as effective as the traditional therapy of clindamycin plus gentamicin. 

Septic shock 1) shock associated with sepsis, usually associated with abdominal and pelvic infection complicating trauma or operations 2) shock associated with septicemia caused by Gram-negative bacteria. 

May be effective in the treatment of acute urinary tract infections caused by susceptible strains of gram-positive and gram-negative bacteria, especially Enterobacter sp. and Escherichia coii. It usually is less effective than other antimicrobial agents in the treatment of urinary tract infections caused by bacteria other than mycobacteria. Consider using only when the more conventional therapy has failed and when the organism has demonstrated sensitivity. 

Most infections are caused by gram-negative bacteria, mostly Escherichia coli. In recurrent UTI, after repeated courses of antimicrobial therapy, other organisms and antibiotic resistance can be expected. 

In the treatment of uncomplicated urinary tract infection caused by gram-negative bacteria, the therapy of choice would be...
