Health awareness and the transition towards clean cooking fuels: Evidence from Rajasthan.

Ensuring affordable, reliable, sustainable and modern energy for all by 2030 is part of the internationally agreed Sustainable Development Goals (SDG7). With roughly 3 billion people still lacking access to clean cooking solutions in 2017, this remains an ambitious task. The use of solid biomass such as wood and cow dung for cooking causes household air pollution resulting in severe health hazards.

Diagnostic response to a cross-border challenge for the Swiss caprine arthritis encephalitis virus eradication program.

Animal trading between countries with different small ruminant lentivirus infectious status is a potential danger for the reintroduction of eradicated genotypes. This was the case in 2017 with the importation of a large flock of seropositive goats into Switzerland. The handling of this case permitted us to test the preventive measures in place.

An Immunodominant Region of the Envelope Glycoprotein of Small Ruminant Lentiviruses May Function as Decoy Antigen.

(1) Background: Small ruminant lentiviruses (SRLV) persist in infected goats that mount a strong humoral immune response characterized by low neutralizing titers. In this study, we characterized the antibody response to SU5, a variable, immunodominant epitope of the envelope glycoprotein of SRLV. We tested the working hypothesis that the variability of SU5 reflects escape from neutralizing antibody.

Detailed analysis of the promoter activity of an attenuated lentivirus.

In spite of an eradication campaign that eliminated clinical cases of caprine arthritis encephalitis virus-induced arthritis in the Swiss goat population, seroconversions are still observed. In the affected flocks, viruses belonging mainly to the small ruminant lentivirus A4 subtype are regularly isolated. These viruses are considered attenuated, except in the mammary gland, where high viral loads and histopathological lesions have been observed.

Generation of a molecular clone of an attenuated lentivirus, a first step in understanding cytopathogenicity and virulence.

Small ruminant lentiviruses infect goats and sheep, inducing clinical disease in a minority of infected animals. Following an eradication campaign, clinical cases may disappear in a population. The complete elimination of these lentiviruses is however difficult to achieve and the spreading of less virulent strains often parallels the elimination of their virulent counterparts.
