Brazilian startup creates therapeutic vaccine to block the transmission of canine visceral leishmaniasis

Fundação de Amparo à Pesquisa do Estado de São Paulo

The vaccine prevents infection spread by inducing an immune response in dogs with visceral leishmaniasis. This response prevents the parasite from being transmitted to the insect vector. This means that if a sand fly bites a vaccinated dog, the parasite cannot be transmitted. Current preventive measures include the use of repellent collars and insecticides, but these options are only moderately effective.

Biotechnology from the tropics: Ecuador fights back against the fungus that withers bananas

Escuela Superior Politecnica del Litoral

Ecuadorian scientists have, for the first time, edited the gene of a fungus that destroys banana plantations. Using an optimized, low-cost CRISPR-Cas9 protocol, they successfully modified the SIX9 gene in Fusarium oxysporum (Foc1), which is linked to banana wilt. This breakthrough opens new avenues for protecting tropical crops and strengthening food security.
