Vector-Borne Animal Diseases

The Arboviral diseases are caused by arthropod-borne viruses, such as Mayaro virus (MAYV), the etiological agent of Mayaro fever. This disease has been drawing the attention of the public health authorities for the increased number of cases likely due to virus adaptation for survival to urban areas as well as infection and multiplication in other vectors insects. Therefore, this work aimed to identify the MAYV infecting Aedes aegypti mosquitoes in Goiânia, the capital of state of Goiás, Brazil. For the development of study, the larvae of A. aegypti were collected in Basic Health Units from different regions of Goiânia then the larvae were grown to adult mosquitoes in controlled laboratory conditions. The female mosquitoes were submitted to the procedure of head and body separation. The RNAs obtained from these samples were analyzed by real-time PCR for identification of arboviruses. We only detect the presence of MAVY in the mosquitoes, in this sense our findings suggest that A. aegypti harbor MAYV in different anatomical sites, and potentially the process of vertical transmission of MAYV can occur in this vector.
