“…López et al 2021;Roberts et al 2019). This is a consequence of the increase of international trips, rapid urbanization with no proper planning, deforestation, climate change and insu cient or ine cient sanitary measures (Cabrera et al 2022;Da Silva et al 2023;Díaz et al 2013;Hubert et al 2018). For instance, a population burst of Aedes albifasciatus (Macquart, 1838) because of El Niñoinduced climate change, led to an invasion of several urban cities from Argentina (Buenos Aires province).…”

The increasing spread of mosquito vectors has made mosquito-borne arboviral diseases a global threat to public health, leading to the urgent need for effective control of such populations. Methods based in the intracellular bacterium Wolbachia Hertig, 1936 are considered environmentally friendly, human-safe, and potentially cost-effective biocontrol strategies to control arboviral diseases. In order to minimize undesirable side effects, it is relevant to understand if Wolbachia ranges in the area and the diversity associated to native infections before implementation. With this purpose, we investigated Wolbachia infection status, diversity and prevalence in populations of Aedes albifasciatus (Macquart, 1838), Aedes fluviatilis (Lutz, 1904), and hybrids of the Culex pipiens (Linnaeus, 1758) complex from Argentina. Additionally, we preliminarily explored the influence of environmental temperature on the Wolbachia prevalence in Ae. fluviatilis. Aedes albifasciatus and Cx. pipiens complex samples were collected in the province of Buenos Aires, and Ae. fluviatilis in the province of Misiones. Aedes albifasciatus was uninfected and infections with strains wFlu and wPip were revealed in Ae. fluviatilis and hybrids of the Cx. pipiens complex, respectively. All strains were fixed or close to fixation and clustered within supergroup B. No effects of environmental temperature on Wolbachia prevalence of Ae. fluviatilis larvae were revealed, at least with the current design. These results provide valuable information on Wolbachia strains found in natural populations of mosquitoes from Argentina that might be used in heterologous infections in the future or must have taken into account when designing control strategies based on Wolbachia infection.

Purpose of Review Mayaro virus is an arbovirus that circulates in a wild cycle transmitted by Haemagogus janthinomys; however, case reports in urban areas suggest that other arthropods could be acting as vectors. It shares several similarities with Chikungunya virus, being highly probable that many cases are being misdiagnosed. The disease caused by this pathogen is known as Mayaro fever, which is restricted to regions of Central and South America, mainly the Amazon rainforest. Cases of Mayaro fever have continuously been increasing, suggesting that Mayaro virus would become another major epidemic arbovirus in America. Recent Findings Four electronic databases were searched for articles in English and Spanish using the keywords “Mayaro” and “case.” A total of 234 cases were retrieved in the 23 selected manuscripts. Of all cases, most of them were male young adults, reported as autochthonous cases occurring mainly in Peru and Brazil, who were performing activities in wild rural areas. Fever, arthralgia, headache, myalgia, and retro-orbital pain were the main clinical manifestations. Most of the patients had laboratory parameters within the normal range, joint complications were evidenced in few cases, and all of them recovered without specific treatment. Summary Mayaro fever appears to be a mild self-limited disease that affects mainly males at productive age that are in contact with wild environments. However, further studies are required to establish its true pathogenic potential of Mayaro virus.
