RESUMEN
Mosquitoes are the main vectors of many infectious diseases, including malaria and yellow fever, which seriously threaten human health across the world. In addition to the use of chemical insecticides, genetic control is a new attempt to currently available interventions used for mosquito vector control. In terms of ecological safety, however, symbiotic control as a novel approach has been proposed for mosquito control. Since there are multiple symbiotic microflora inhabiting in a variety of tissues of mosquitoes, including the digestive tract, they may affect the transmission of mosquito-borne infectious diseases through affecting the lifespan, reproductive competence, and vector competence of the host. In this review, the interactions between symbionts in mosquitoes were summarized, and the research progress of mosquito-associated symbionts in the management of mosquitoborne infectious diseases was reviewed.
RESUMEN
OBJECTIVE@#To study the extraction and analysis of DNA from trace bloodstains on the adsorbent object.@*METHODS@#DNA was extracted by Chelex-100, QIAamp Mini Kit, and modified QIAamp Mini Kit, respectively. The extracted DNA was amplified and short tandem repeat (STR) loci were genotyped by multiplex PCR procedures, and then analyzed by ABI 3100 Genetic Analyzer.@*RESULTS@#The STR loci could be better genotyped with modified QIAamp Mini Kit, compared to poorer genotyping results obtained with Chelex-100 extraction method and QIAamp Mini Kit.@*CONCLUSION@#Our data indicate that DNA extracted from trace bloodstains on adsorbent object with modified QIAamp Mini Kit serves a better DNA template. for amplification and genotyping.
