Genetic Testing for Leishmania spp. in Sandflies
Leishmaniasis is a parasitic disease caused by protozoa of the genus Leishmania. The vector responsible for transmitting these parasites to humans and animals is primarily sandflies, which belong to the family Psychodidae. Genetic testing has become an essential tool in diagnosing Leishmania infections, particularly when dealing with sandflies. This service provides accurate genetic identification of Leishmania spp. within sandfly populations, aiding in the epidemiological surveillance and control strategies for leishmaniasis.
The process involves the extraction of DNA from sandflies captured in endemic areas. Following extraction, PCR-based techniques such as real-time quantitative PCR (qPCR) are employed to detect specific sequences indicative of Leishmania spp. This method ensures high sensitivity and specificity, making it a reliable tool for identifying even low-level infections within sandfly populations.
Our laboratory uses advanced next-generation sequencing technologies to provide comprehensive genetic profiling. This includes the identification of species-specific markers and differentiation between different strains of Leishmania. The ability to differentiate among various strains is crucial as it helps in understanding the geographical distribution, transmission dynamics, and potential for drug resistance within sandfly populations.
For quality assurance, we follow strict protocols outlined by international standards such as ISO 15189 and EN ISO/IEC 17025. These standards ensure that our laboratory maintains high levels of proficiency in both methodology and instrumentation. Our methodologies are validated using reference materials provided by reputable organizations like the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC).
The importance of genetic testing extends beyond mere diagnosis; it also plays a critical role in public health policy formulation. By providing accurate data on sandfly populations, our service supports evidence-based interventions aimed at reducing the incidence of leishmaniasis. This includes targeted vector control measures and improved surveillance systems that can predict outbreaks more accurately.
