Revisiting the Phlebotominae subfamily records in Bahia, Brazil.

Brazil is one of the countries that concentrates 90% of all tegumentary and visceral leishmaniases cases and Bahia is one of the highly affected states. In the present report, we consolidated secondary data from several complementary databases that allowed us to record the sand fly species identified including areas of Leishmania spp. transmission in the state of Bahia.

Clinical, epidemiological and transmission cycle aspects of leishmaniasis urbanization in Barreiras, Bahia, Brazil.

Leishmaniasis remains one of the world's leading infectious diseases and a public health problem for Bahia and Brazil. We made a retrospective cohort study of leishmaniasis cases reported between 2007 and 2016 in the Barreiras city, an important agribusiness city whose urbanization process was recent. Leishmaniasis presented epidemiological data with similar characteristics of the disease in other regions of the Brazil, that is, with the highest prevalence of visceral leishmaniasis found in children, while cutaneous leishmaniais was found in adults.

Increased capture of Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae) by removing one ADULTRAP component.

Introduction: Aedes aegypti is the main vector responsible for the transmission of numerous arboviruses. Adultrap® has been developed to catch these insects.

Methods: We tested the effectiveness of capturing adults with and without one of the components of Adultrap®.

Experimental study on the action of larvicides in Aedes aegypti populations collected in the Brazilian municipality of Itabuna, Bahia, under simulated field conditions.

Objective: to evaluate, under simulated field conditions, the efficacy of pyriproxyfen (juvenile hormone), novaluron (chitin inhibitor) and spinosad (biolarvicide) in controlling Aedes aegypti.

Methods: periodic exposition of Ae. aegypti larvae collected in Itabuna, BA, Brazil, to recipients treated with larvicides and comparison of residual effect of treatment with the Rockefeller strain.

Leishmania amastigotes as targets for drug screening.

Direct drug screening against the mammalian stage of Leishmania has been hampered by cost and the time consuming effort required to accomplish it. The ability to derive transgenic Leishmania expressing reporter genes opened up new possibilities for the development of drug screening tests. Further developments to standardize and gather multiple informations could now be envisionned.
