- Basic science
What is the background of the project?
Brucellosis, caused by Brucella spp., a Gram-negative coccobacillus, is a zoonosis of worldwide occurrence. This disease is associated with high morbidity in animals and humans leading to important economic losses and public health problems in many countries. To prevent bovine brucellosis, immunization with the vaccinal B. abortus RB51 and B. abortus S19 strains has been implemented. Although both vaccines have been effective they cannot eradicate the pathogen and they are pathogenic for humans. It is therefore necessary to develop an effective and safe vaccine able to trigger host immunity against B. abortus. A DNA vaccine that safely expresses immunogens protecting against Brucella infection could be more effective for controlling brucellosis. Perform some immunological techniques necessary to evaluate some immunological parameters. Enzyme-liked immunosorbent assay (ELISA) for antibody and cytokine, Lymphocyte proliferation.
What is the aim of the project?
Perform some immunological techniques necessary to evaluate some immunological parameters.
What techniques and methods are used?
Enzyme-liked immunosorbent assay (ELISA) for antibody and cytokine, Lymphocyte proliferation.
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- If the project includes “lab work”
- the student will take active part in the practical aspect of the project
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
Collaborate with students who are in thesis. How to evaluate immunological parameters in a research where vaccines are developed
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
depends on the student
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- No specific outcome is expected
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
have basic computer skills in a laboratory, basic concepts in immunology; have a basic course in immunology or some related course and basic concepts in Microbiology.
Are there any legal limitations in the student’s involvement
