ABSTRACTThe mosquitoes Aedes aegypti (L.) and Ae. albopictus Skuse are the major vectors of dengue, Zika, yellow fever and chikungunya viruses worldwide. Wolbachia, an endosymbiotic bacterium present in many insects, is being utilized in novel vector control strategies to manipulate mosquito life history and vector competence to curb virus transmission. Earlier studies have found that Wolbachia is commonly detected in Ae. albopictus but rarely detected in Ae. aegypti. In this study, we used a two-step PCR assay to detect Wolbachia in wild-collected samples of Ae. aegypti. The PCR products were sequenced to validate amplicons and identify Wolbachia strains. A loop-mediated isothermal amplification (LAMP) assay was developed and used for detecting Wolbachia in selected mosquito specimens as well. We found Wolbachia in 85/148 (57.4%) wild Ae. aegypti specimens from various cities in New Mexico and in 2/46 (4.3%) from St. Augustine, Florida. We did not detect Wolbachia in 94 samples of Ae. aegypti from Deer Park, Harris County, Texas. Wolbachia detected in Ae. aegypti from both New Mexico and Florida was the wAlbB strain of Wolbachia pipientis. A Wolbachia positive colony of Ae. aegypti was established from pupae collected in Las Cruces, New Mexico in 2018. The infected females of this strain transmitted Wolbachia to their progeny when crossed with males of Rockefeller strain of Ae. aegypti, which does not carry Wolbachia. In contrast, none of the progeny of progeny of Las Cruces males mated to Rockefeller females were infected with Wolbachia.

Objetivo: sintetizar as ações desenvolvidas para o enfrentamento ao Aedes aegypti no contexto brasileiro. Método: trata-se de um estudo bibliográfico, descritivo, tipo revisão integrativa. Realizou-se a busca na MEDLINE, LILACS e BDENF. Utilizaram-se os filtros: texto completo disponível; idioma (português, inglês e espanhol), tipo de documento (artigo) e ano de publicação (2013-2018). Organizou-se o processo de definição e seleção dos estudos por meio do fluxograma PRISMA. Utilizou-se o software IRAMUTEQ para o processamento e a análise dos dados. Analisaram-se os dados a partir da Classificação Hierárquica Descendente e da nuvem de palavras. Resultados: selecionaram-se 31 estudos. Originaram-se seis classes com as seguintes estratégias: fungos entomopatogênicos; peixes larvívoros; Wolbachia pipientis; técnicas RILD e SIT; inseticidas botânicos; larvicidas Diflubenzuron e Deltramina; Piriproxifeno; monitoramento tecnológico; visitas regulares pelo ACS e ACE; abordagem ecossaúde; MIV e campanhas. Conclusão: conclui-se que há uma variedade de estratégias de enfrentamento às arboviroses e o quão são necessários o aperfeiçoamento e o desenvolvimento de técnicas inovadoras para o controle deste agravo.

Method: this is a bibliographic, descriptive, integrative review study. The search was performed at MEDLINE, LILACS and BDENF. The filters were used: full text available; language (Portuguese, English and Spanish), type of document (article) and year of publication (2013-2018). The process of definition and selection of studies was organized through the PRISMA flowchart. IRAMUTEQ software was used for data processing and analysis. Data was analyzed from Descending Hierarchical Classification and word cloud. Results: 31 studies were selected. Six classes originated with the following strategies: entomo-pathogenic fungi; larval fish; Wolbachia pipientis; RILD and SIT techniques; botanical insecticides; larvicides Diflubenzuron and Deltramine; Pyriproxyfen; technological monitoring; regular visits by ACS and ACE; eco-health approach; MIV and campaigns. Conclusion: it is concluded that there are a variety of strategies for coping with arboviruses and how much the improvement and development of innovative techniques for the control of this disease are necessary.

ABSTRACTZika virus is a global public health emergency due to its association with microcephaly, Guillain-Barré syndrome, neuropathy, and myelitis in children and adults. A total of 87 countries have had evidence of autochthonous mosquito-borne transmission of Zika virus, distributed across four continents, and no antivirus therapy or vaccines are available. Therefore, several strategies have been developed to target the main mosquito vector, Aedes aegypti, to reduce the burden of different arboviruses. Among such strategies, the use of the maternally-inherited endosymbiont Wolbachia pipientis has been applied successfully to reduce virus susceptibility and decrease transmission. However, the mechanisms by which Wolbachia orchestrate resistance to ZIKV infection remain to be elucidated. In this study, we apply isobaric labeling quantitative mass spectrometry-based proteomics to quantify proteins and identify pathways altered during ZIKV infection; Wolbachia infection; co-infection with Wolbachia/ZIKV in the Ae. aegypti heads and salivary glands. We show that Wolbachia regulates proteins involved in ROS production, regulates humoral immune response, and antioxidant production. The reduction of ZIKV polyprotein in the presence of Wolbachia in mosquitoes was determined by mass spectrometry and corroborates the idea that Wolbachia helps to block ZIKV infections in Ae. aegypti. The present study offers a rich resource of data that may help to elucidate mechanisms by which Wolbachia orchestrate resistance to ZIKV infection in Ae. aegypti, and represents a step further on the development of new targeted methods to detect and quantify ZIKV and Wolbachia directly in complex tissues.HighlightsThe abundance of ZIKV polyprotein is reduced in the presence of WolbachiaShotgun proteomics quantifies ZIKV and Wolbachia proteins directly in tissuesWolbachia regulates proteins involved in ROS productionWolbachia regulates humoral immune response and antioxidant productionMetabolism and detoxification processes were associated with mono infections

Zika virus (ZIKV) is a global public health emergency due to its association with microcephaly, Guillain-Barré syndrome, neuropathy, and myelitis in children and adults. A total of 87 countries have had evidence of autochthonous mosquito-borne transmission of ZIKV, distributed across four continents, and no antivirus therapy or vaccines are available. Therefore, several strategies have been developed to target the main mosquito vector, Aedes aegypti, to reduce the burden of different arboviruses. Among such strategies, the use of the maternally-inherited endosymbiont Wolbachia pipientis has been applied successfully to reduce virus susceptibility and decrease transmission. However, the mechanisms by which Wolbachia orchestrate resistance to ZIKV infection remain to be elucidated. In this study, we apply isobaric labeling quantitative mass spectrometry (MS)-based proteomics to quantify proteins and identify pathways altered during ZIKV infection; Wolbachia infection; co-infection with Wolbachia/ZIKV in the A. aegypti heads and salivary glands. We show that Wolbachia regulates proteins involved in reactive oxygen species production, regulates humoral immune response, and antioxidant production. The reduction of ZIKV polyprotein in the presence of Wolbachia in mosquitoes was determined by MS and corroborates the idea that Wolbachia helps to block ZIKV infections in A. aegypti. The present study offers a rich resource of data that may help to elucidate mechanisms by which Wolbachia orchestrate resistance to ZIKV infection in A. aegypti, and represents a step further on the development of new targeted methods to detect and quantify ZIKV and Wolbachia directly in complex tissues.
