Molecular evidence of pathogens and endosymbionts in the black horse fly Osca lata (Diptera: Tabanidae) in Southern Chile.

Little is known about the role of horse flies in potential pathogen transmission in Chile. This study provides evidence of the molecular detection of microorganisms in southern Chile. In the present study, adult Osca lata horse flies were trapped from Punucapa (39°45'06"S/73°16'08"W, Región de Los Ríos) and Puyehue (40°39'10"S/72°10'57"W, Región de Los Lagos), Chile.

Encapsulation of D-Limonene into O/W Nanoemulsions for Enhanced Stability.

The present study aimed to investigate the physical stability in terms of (droplet size, pH, and ionic strength) and chemical stability in terms of (retention) of D-limonene (LM) in the nanoemulsions after emulsification as well as after storing them for 30 days under different temperatures (5 °C, 25 °C, and 50 °C). LM is a cyclic monoterpene and a major component extracted from citrus fruits. The modification of disperse phase with soybean oil (SB) and a nonionic emulsifier (Tween 80) was adequate to prepare stable LM-loaded nanoemulsions.

Chagas disease in northern Chile: Detection of Trypanosoma cruzi in children, dogs and triatomine bugs.

Chagas disease is an anthropozoonotic disease caused by the protozoan Trypanosoma cruzi, transmitted by triatomine vectors. In Chile, there are four species of triatomine bugs that are potential vectors of T. cruzi, being Triatoma infestans the main vector in endemic areas of the country.

Modeling the Potential Distribution of the Malaria Vector Theobald (Diptera: Culicidae) in Arid Regions of Northern Chile.

The extreme north of Chile presents a subtropical climate permissive of the establishment of potential disease vectors. (.) is distributed from the south of the United States to the north of Argentina and Chile, and is one of the main vectors of malaria in Latin America.
