Composition of sand fly fauna (Diptera: Psychodidae) and detection of Leishmania DNA (Kinetoplastida: Trypanosomatidae) in different ecotopes from a rural settlement in the central Amazon, Brazil

BACKGROUND: Phlebotomine sand flies (Diptera: Psychodidae) are vectors of Leishmania species, the etiological agents of leishmaniasis, which is one of the most important emerging infectious diseases in the Americas. In the state of Amazonas in Brazil, anthropogenic activities encourage the presence of these insects around rural homes. The present study aimed to describe the composition […]

Is there still room to explore cyclodextrin glycosyltransferase-producers in Brazilian biodiversity?

In the present work, different Brazilian biomes aiming to identify and select cyclodextringlycosyltransferase-producer bacteria are explored. This enzyme is responsible for converting starch to cyclodextrin, which are interesting molecules to carry other substances of economic interest applied by textile, pharmaceutical, food, and other industries. Based on the enzymatic index, 12 bacteria were selected and evaluated, […]

Contribution of efflux to colistin heteroresistance in a multidrug resistant acinetobacter baumannii clinical isolate

PURPOSE: The mechanisms underlying colistin heteroresistance in Acinetobacter baumannii are not fully understood. Here, we investigated the role of efflux in colistin-heteroresistant populations of a multidrug-resistant (MDR) A. baumannii clinical isolate. METHODOLOGY: Three colistin-resistant A. baumannii strain variants isolated from the same clinical sample were studied for the presence of heteroresistance to colistin by drug […]
