Evaluation of target specificity of antibacterial agents using Staphylococcus aureus ddlA mutants and D-cycloserine in a silkworm infection model.
The availability of a silkworm larva infection model to evaluate the therapeutic effectiveness of antibiotics was examined. The 50% effective doses (ED50) of D-cycloserine against the Staphylococcus aureus ddlA mutant-mediated killing of larvae were remarkably lower than those against the parental strain-mediated killing of larvae. Changes in MICs and ED50 of other antibiotics were negligible, ...
متن کاملEvaluation of therapeutic effects and pharmacokinetics of antibacterial chromogenic agents in a silkworm model of Staphylococcus aureus infection.
The therapeutic effect of dye compounds with antibacterial activity was evaluated in a silkworm model of Staphylococcus aureus infection. Among 13 chromogenic agents that show antibacterial activity against S. aureus (MIC = 0.02 to 19 μg/mL), rifampicin had a therapeutic effect. The ED(50) value in the silkworm model was consistent with that in a murine model. Other 12 dyes did not increase sur...

Background and Objective: Staphylococcus aureus is an important pathogen causing a wide range of infections in hospitals and is known due to its resistance to antibiotics. Novel methods of nanotechnology and the effective combination of different antimicrobial mechanisms can be compelling approaches to treat infectious diseases. The aim of this study was to investigate the antimicrobial effect ...
متن کاملA silkworm model of pathogenic bacterial infection.
Silkworms are invertebrate animals that are killed by bacteria pathogenic against humans, such as Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa, and Vibrio cholerae. Injection into the hemolymph of antibiotics that are clinically used for human patients abolishes the killing effects. There are several advantages to using silkworms as an infection model, such as low cost,...
متن کاملBacteriophage ΦSA012 Has a Broad Host Range against Staphylococcus aureus and Effective Lytic Capacity in a Mouse Mastitis Model
Bovine mastitis is an inflammation of the mammary gland caused by bacterial infection in dairy cattle. It is the most costly disease in the dairy industry because of the high use of antibiotics. Staphylococcus aureus is one of the major causative agents of bovine mastitis and antimicrobial resistance. Therefore, new strategies to control bacterial infection are required in the dairy industry. O...
