The gene cyt1Aa is one of the genes in the complex determining the mosquito larvicidity of Bacillus thuringiensis subsp. israelensis. Previous cloning in Escherichia coli resulted in a 48-bp addition upstream, encoding a chimera. Here, cyt1Aa was recloned without the artifact, and its toxicity against Aedes aegypti larvae and host E. coli cells was retested.
