Cefixime is a broad spectrum cephalosporin antibiotic and is commonly used to treat bacterial infections of the ear, urinary tract, and upper respiratory tract. The following represents MIC susceptibility data for a few medically significant microorganisms: [15] Escherichia coli: 0.015 μg/mL – 4 μg/mL
The elimination half-life of moxifloxacin is 11.5 to 15.6 hours (single-dose, oral). [45] About 45% of an oral or intravenous dose of moxifloxacin is excreted as unchanged drug (about 20% in urine and 25% in feces). A total of 96 ± 4% of an oral dose is excreted as either unchanged drug or known metabolites.
However, E. coli are extremely sensitive to such antibiotics as streptomycin or gentamicin. Recent research suggests treatment of enteropathogenic E. coli with antibiotics may significantly increase the chance of developing haemolytic-uremic syndrome. [12]
After gaining entry to the bladder, E. Coli are able to attach to the bladder wall and form a biofilm that resists the body's immune response. [7] Escherichia coli is the single most common microorganism, followed by Klebsiella and Proteus spp., to cause urinary tract infection. Klebsiella and Proteus spp., are frequently associated with stone ...
Nitrofurantoin and the quinolone antibiotics are mutually antagonistic in vitro. It is not known whether this is of clinical significance. [9] Resistance to nitrofurantoin may be chromosomal or plasmid-mediated and involves inhibition of nitrofuran reductase. [55] Acquired resistance in E. coli continues to be rare.
In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant.

Ciprofloxacin is a fluoroquinolone antibiotic used to treat a number of bacterial infections. [5] This includes bone and joint infections, intra-abdominal infections, certain types of infectious diarrhea, respiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others. [5]
Carbenicillin is a bactericidal antibiotic belonging to the carboxypenicillin subgroup of the penicillins. [2] It was discovered by scientists at Beecham and marketed as Pyopen. It has Gram-negative coverage which includes Pseudomonas aeruginosa but limited Gram-positive coverage.
