The 2025 UNAIDS targets prioritize reaching all subpopulations living with HIV and those at risk for HIV as the only pathway to achieving control of the HIV epidemic. This has brought to the fore the importance of addressing the needs of key marginalized groups and placing such communities at the center of HIV response strategies. However, the COVID-19 pandemic has resulted in a setback in terms of confronting HIV. With this in mind, it is important not only to protect services within HIV responses among key populations, but also to expand such services to meet the UNAIDS 2025 targets. Without this, gains in controlling COVID-19 may be achieved at the expense of losses in controlling the spread of HIV, which had been achieved after sustained and resource-intensive actions., Competing Interests: The authors declare no competing interests., (© 2022 The Author(s).)

Bacillus thuringiensis (Bt) is a Gram-positive soil bacterium that has been recognized as an effective bioinsecticide active against plant, animal and human pathogenic and disease vector insects. During its sporulation phase, Bt produces crystals consisting of δ-endotoxins, which upon ingestion kill specifically insect larvae. Bt subsp. israelensis ( Bti ) is very active against dipteran insects. Bti based bioinsecticides are considered as a sustainable solution to control the Dipteran insects responsible of plant, animal and human diseases. In this study, Bti strains isolated from Qatar soil were analyzed for their insecticidal activities against the dipteran insect Aedes aegypti Bora Bora ( Culicidae, Diptera ) and for their δ-endotoxins yields per cell. Among the local Bti strains, four exceptional strains producing spherical crystals, were found to be more insecticidal than the reference strain Bti H14. When tested for their δ-endotoxin yield, the Bti QBT217 strain, producing typical spherical crystals and having the best insecticidal activity, was recognized as the best candidate strain for potential bioinsecticide production and biological control of dipteran insects, particularly the disease vector insect A. aegypti ., (© 2020 Published by Elsevier Ltd.)
