Abstract: | Objectives: Cutaneous leishmaniasis (CL) is considered an overlooked public health threat in KSA. CL is endemic to several Saudi regions, including Al Ahsa City, Eastern KSA. To our knowledge, no prior molecular identification of Leishmania parasites in vectors in Al Ahsa has been published. The aim of this study was to perform molecular identification of Leishmania species in sand flies collected from Al Ahsa. Methods: This cross-sectional study was conducted in Al Ahsa from July 2020 to May 2021. Sand flies were collected from the three areas with the highest rates of CL cases and sand flies, according to data from the Vector Borne Diseases Prevention Center in Al Ahsa. CDC miniature light traps and sticky traps were used to collect sand flies. Pools of 3e10 female sand flies were subjected to genomic DNA extraction. The extracted DNA was then amplified with a protocol targeting the Leishmania genus and using species-specific primers. For Leishmania species identification, a PCR-restriction fragment length polymorphism (PCR-RFLP) method was used. Results: Ten of 113 pools of samples tested positive for the Leishmania genus, according to our experimental protocol. Characterization of Leishmania species by PCR-RFLP established Leishmania major as the only species found in the collected sand flies. Conclusion: This is the first documentation of molecular identification of Leishmania species in phlebotomine sand flies in the Al Ahsa region. L. major was the only species identified in our study. Further comprehensive research investigating the vectors and reservoirs will be crucial to establish the dynamics of transmission of Leishmania in Al Ahsa. |
