عنوان انگلیسی Blood Meal Identification in Field-Captured Sand flies: Comparison of PCR-RFLP and ELISA Assays
چکیده انگلیسی مقاله Background: We aimed to develop a PCR-RFLP assay based on available sequences of putative vertebrate hosts to iden­tify blood meals ingested by field female sand fly in the northwest of Iran. In addition, the utility of PCR-RFLP was compared with ELISA as a standard method. Methods: This experimental study was performed in the Insect Molecular Biology Laboratory of School of Public Health, Tehran University of Medical Sciences, Iran in 2006-2007. For PCR-RFLP a set of conserved vertebrate prim­ers were used to amplify a part of the host mitochondrial cytochrome b (cyt b) gene followed by digestion of the PCR products by Hae III enzyme. Results: The PCR-RFLP and ELISA assays revealed that 34% and 27% of field-collected sand flies had fed on hu­mans, respectively. Additionally, PCR-RFLP assays could reveal specific host DNA as well as the components of mixed blood meals. Results of PCR-RFLP assay showed that the sand flies had fed on cow (54%), human (10%), dog (4%), human and cow (21%), dog and cow (14%), and human and dog (3%). Conclusion: The results can provide a novel method for rapid diagnosis of blood meal taken by sandflies. The advan­tages and limitations of PCR and ELISA assays are discussed.
