Quantification of Leishmania sp for real time PCR:

The department of Veterinary and  I + D of the Laboratory Echevarne has developed a new technology by means of real time PCR for the detection and quantification of Leishmania sp.

This technology quantifies the number of parasites of Leishmania sp. on the basis of the total quantity of nucleate present cells in the sample (parasites / cells). The most recent publications in specialized magazines of the sector demonstrate the great usefulness of this technology for the monitoring of the treatment in dogs affected for leishmaniosis.

The Leishmania is located preferably in the phagocytal system for what the biological counterfoils most adapted for his detection continue being bony marrow, punctures of lymphatic ganglions infartados, compatible leather injuries with the disease, biopsies and even peripheral blood in EDTA.

The limit of detection of the technology has been established in 0.3 parásitos/ml and that of quantification in 6.5x10-5 parasites / parasitic. The average relation between the concentration awaited and obtained in the validation of the technology is lower than 0.3 log.
