Yellow fever virus investigation in tissues of vampire bats Desmodus rotundus during a wild yellow fever outbreak in Brazilian Atlantic Forest.

In the last decade a large outbreak of Yellow Fever (YF) has been observed in Brazilian Atlantic Forest region, traditionally a non-endemic area. In this scenario, the role of wild mammal species as YF reservoirs can be questioned, especially the hematophagous bat, Desmodus rotundus. So, the objective of this study was to analyze molecularly the presence of the YF virus (YFV) in hematophagous bats during a YF outbreak in Brazil.

Zika Virus Envelope Protein Domain III Produced in Has the Potential for Diagnostic Applications.

Zika virus (ZIKV) represents a global human health threat and it is related to severe diseases such as congenital Zika syndrome (CZS) and Guillain-Barré syndrome (GBS). There is no vaccine available nor specific antiviral treatment, so developing sensitive, specific, and low-cost diagnostic tests is necessary. Thus, the objective of this work was to produce the Zika virus envelope protein domain III (ZIKV-EDIII) in KM71H and evaluate its potential for diagnostic applications.

Adsorption of neutral red dye by chitosan and activated carbon composite films.

Research indicates the use of adsorbent materials to remove pollutants from wastewater and effluents, which can be obtained from renewable materials such as biomass, biopolymers (chitosan) or composites. Thus, the objective of this work was to produce and evaluate activated carbon (AC) and chitosan composite films as adsorbents of neutral red dye. AC films were produced using CO and water vapor.

Efficient Plant Production of Recombinant NS1 Protein for Diagnosis of Dengue.

Dengue fever is endemic in more than 120 countries, which account for 3.9 billion people at risk of infection worldwide. The absence of a vaccine with effective protection against the four serotypes of this virus makes differential molecular diagnosis the key step for the correct treatment of the disease.

NS1 Recombinant Proteins Are Efficiently Produced in and Have Great Potential for Use in Diagnostic Kits for Dengue Virus Infections.

Dengue is one of the major diseases causing global public health concerns. Despite technological advances in vaccine production against all its serotypes, it is estimated that the dengue virus is responsible for approximately 390 million infections per year. Laboratory diagnosis has been the key point for the correct treatment and prevention of this disease.
