Investigational drug(s) / intervention(s)

Isolation of anti-Pseudomonas antibodies from type B lymphocytes

Isolation of anti-Pseudomonas antibodies from type B lymphocytes: Blood sampling. Isolation of mononuclear cells from human peripheral blood by density gradient centrifugation. Identification of functional anti-Pseudomonas antibodies by ELISA and cellular infection assays.

Study summary

Pseudomonas aeruginosa is a pathogenic bacteria for human, especially in hospital settings. It can sometimes be multi-resistant to many or even to all antibiotics usually used for its treatment.

The aim of the study is to isolate and produce therapeutic antibodies against the bacteria Pseudomonas aeruginosa in order to provide an alternative treatment to antibiotics in case of infection with an antibiotic-resistant strain of Pseudomonas aeruginosa.
