INFECTIOUS DISEASES I
Learning outcomes of the course unit
With regard to the most important infections affecting domestic animals caused by bacteria, mycoplasmas, rickettsias and chlamydias, the course aims to teach the necessary concepts and methods to enable students to achieve the following objectives:
1. make, in practice, the clinical diagnosis and appropriate organ sampling for an experimental diagnosis with a view to confirming or excluding a suspected disease;
2. learn the criteria required to interpret and evaluate the reliability of the various diagnostic tests most widely used in medical practice;
3. acquire knowledge of the batch methods adopted for disease control and their relative economic aspects;
4. acquire knowledge of the preparations available for animal vaccinations, their use, evaluation of the results obtained, and the legislation governing their use;
5. acquire knowledge of the legislative measures adopted for diseases subject to health measures and be able to adopt urgent measures in the presence of an outbreak of contagious disease;
6. be aware of the reasons for the choice of the batch measures adopted for the various diseases on the basis of the health situation of the Country in question and that of the EU;
7. be able to justify and apply suitable measures in the event of a suspected or confirmed outbreak of an infectious disease;
8. have knowledge of the forms and paperwork provided for by the current legislation on veterinary monitoring;
9. be able to conduct an epidemiological survey aiming at identifying the origin and spread of diseases caused by infections.
10. Acquire knowledge ofthe organisation of the health service

Assessment methods and criteria
The verification of the achievement of the objectives foreseen by the teaching, is made with a single exam and including the Veterinary Police.
The exam includes an oral exam, where the student must answer 4 questions, addressing the aspects:
1 question regarding: Inborn and acquired immunity
1 question regarding: Pathogen host interaction
1 question concerning: pathogenesis of the infectious disease taken in question
1 related question: profiling and therapy related to the infectious disease taken in question.
The final purpose is to ascertain if the student has reached the goal of knowledge, to know how to communicate and to know how to use it in an autonomous way.
The result was assigned to the overall assessment of the answers from the student. The final mark is expressed in thirtieths.
Students with a sense of discipline (DSA), certified according to the law n. 170/2010 will be granted the benefits provided by law.
