Seasonal population dynamics of the primary yellow fever vector Haemagogus leucocelaenus (Dyar & Shannon) (Diptera: Culicidae) is mainly influenced by temperature in the Atlantic Forest, southeast Brazil

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Southeast Brazil has recently experienced a Yellow Fever virus (YFV) outbreak where the mosquito Haemagogus leucocelaenus was a primary vector. Climatic factors influence the abundance of mosquito vectors and arbovirus transmission. OBJECTIVES We aimed at describing the population dynamics ...

Development and characterization of a packaging cell line for pseudo-infectious yellow fever virus particle generation

Abstract INTRODUCTION: Pseudo-infectious yellow fever viral particles (YFV-PIVs) have been used to study vaccines and viral packaging. Here, we report the development of a packaging cell line, which expresses the YFV prM/E proteins. METHODS: HEK293 cells were transfected with YFV prM/E and C (84 nt) ...

Metagenomic analysis reveals Hepatitis A virus in suspected yellow fever cases in Brazil

Mem. Inst. Oswaldo Cruz; 113 (1), 2018
Using a metagenomic approach, we identified hepatitis A virus among cases of acute febrile illnesses that occurred in 2008-2012 in Brazil suspected as yellow fever. These findings reinforce the challenge facing routine clinical diagnosis in complex epidemiological scenarios....

Genome analysis of yellow fever virus of the ongoing outbreak in Brazil reveals polymorphisms

Mem. Inst. Oswaldo Cruz; 112 (6), 2017
The current yellow fever outbreak in Brazil is the most severe one in the country in recent times. It has rapidly spread to areas where YF virus (YFV) activity has not been observed for more than 70 years and vaccine coverage is almost null. Here, we sequenced the whole YFV genome of two naturally infect...

Construction and characterization of a recombinant yellow fever virus stably expressing Gaussia luciferase

An. acad. bras. ciênc; 89 (3,supl), 2017
ABSTRACT Yellow fever is an arthropod-borne viral disease that still poses high public health concerns, despite the availability of an effective vaccine. The development of recombinant viruses is of utmost importance for several types of studies, such as those aimed to dissect virus-host interactions and...
