In Vitro Bactericidal Activity of Trimethoprim-Sulfamethoxazole/Colistin Combination Against Carbapenem-Resistant Klebsiella pneumoniae Clinical Isolates.

Summary of "In Vitro Bactericidal Activity of Trimethoprim-Sulfamethoxazole/Colistin Combination Against Carbapenem-Resistant Klebsiella pneumoniae Clinical Isolates."

Carbapenem-resistant Klebsiella pneumoniae (CRKP) has emerged as a formidable health challenge in recent years owing to the shortage of effective antibiotics. Colistin is the last and sometimes the only therapeutic option for CRKP infections. Unfortunately, resistance to colistin monotherapy is likely to develop. CRKP in China reportedly exhibit low rates of resistance to trimethoprim-sulfamethoxazole. The aim of this study was to evaluate the in vitro efficacy of trimethoprim-sulfamethoxazole in combination with colistin against four CRKP clinical isolates. The trimethoprim-sulfamethoxazole/colistin combination rapidly killed all four of the tested isolates after 2 h up to 24 h. Trimethoprim-sulfamethoxazole is one of the few remaining antimicrobials with some activity against CRKP. In particular, combined with colistin, trimethoprim-sulfamethoxazole might be promising for the treatment of CRKP infections.

Synergistic Activity of Niclosamide in Combination With Colistin Against Colistin-Susceptible and Colistin-Resistant and .

Colistin is among the few antibiotics effective against multidrug-resistant and clinical isolates. However, in the last few years, colistin-resistant and strains have emerged. Therefore, combinati...

Triple combination of meropenem, colistin and tigecycline was bactericidal in a dynamic model despite mere additive interactions in chequerboard assays against carbapenemase-producing Klebsiella pneumoniae isolates.

Combination schemes are commonly used for the treatment of infections due to carbapenemase-producing Klebsiella pneumoniae (CP-Kp). We therefore investigated the in vitro effectiveness of double and t...

Medical and Biotech [MESH] Definitions

A pyrimidine inhibitor of dihydrofolate reductase, it is an antibacterial related to PYRIMETHAMINE. The interference with folic acid metabolism may cause a depression of hematopoiesis. It is potentiated by SULFONAMIDES and the TRIMETHOPRIM-SULFAMETHOXAZOLE COMBINATION is the form most often used. It is sometimes used alone as an antimalarial. TRIMETHOPRIM RESISTANCE has been reported.

A drug combination with broad-spectrum antibacterial activity against both gram-positive and gram-negative organisms. It is effective in the treatment of many infections, including PNEUMOCYSTIS PNEUMONIA in AIDS.

This drug combination has proved to be an effective therapeutic agent with broad-spectrum antibacterial activity against both gram-positive and gram-negative organisms. It is effective in the treatment of many infections, including PNEUMOCYSTIS PNEUMONIA in AIDS.

The natural bactericidal property of BLOOD due to normally occurring antibacterial substances such as beta lysin, leukin, etc. This activity needs to be distinguished from the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy, which is measured by a SERUM BACTERICIDAL TEST.

Cyclic polypeptide antibiotic from Bacillus colistinus. It is composed of Polymyxins E1 and E2 (or Colistins A, B, and C) which act as detergents on cell membranes. Colistin is less toxic than Polymyxin B, but otherwise similar; the methanesulfonate is used orally.
