To seek a new delivery system of vaccine for infectious bronchitis virus (IBV), transgenic potato expressing full-length spike (S) protein of IBV was produced and its immunogenicity in chickens was investigated. One to three copies of S gene of IBV were randomly and stably inserted into potato
To check the feasibility of expression of the immunogenic gene of avian coronavirus infectious bronchitis virus (IBV) in plants, the transformation of S1 gene of IBV into potato and the immunogenicity of its expression product was studied. The S1 gene of IBV-ZJ971 strain was inserted into plasmid
Exposure to diatomaceous earth with low crystalline silica content (< 1%) is rarely reported to cause pneumoconiotic disease, whereas airway obstruction and bronchitis are more frequently reported. We investigated the occurrence of pneumoconiosis and airflow limitation in 172 male workers from 5
The expression of infectious bronchitis virus (IBV) S1 glycoprotein in potatoes and its immunogenicity in mice and chickens were investigated. Potato plants were genetically transformed with a cDNA construct encoding the IBV S1 glycoprotein with the Agrobacterium system. Genomic DNA and mRNA
OBJECTIVE
Livestock farming has been recognized as a risk factor for chronic bronchitis (CB). The role of crop farming, however, has been less studied. We sought to assess the role of a large range of farming activities on the risk of CB in the French agricultural cohort AGRICAN (AGRIculture and
OBJECTIVE
To identify the terms used by mothers to refer to diseases, signs and symptoms related to acute respiratory illnesses (ARI), alarming signs which should motivate them to seek medical attention, and to describe common home practices of disease care and treatment.
METHODS
An ethnographic
BACKGROUND
Hypoxis species are used extensively in traditional medicine in southern Africa for several ailments including tuberculosis, chest infections, and nervous and urinary disorders. Several other claims have been made for extracts emanating from Hypoxis species and have led to the production
Solanum melongena L. commonly known as the eggplant or brinjal comes from the family of Solanaceae, sharing the same ancestor with the tomato and potato. It is an economically important crop worldwide, being well studied for its medicinal properties, nutritional values and its role as an alternative
