The objective of the Avian Pathology teaching is represented by in-depth study of the major infectious diseases occurring in poultry. The student must be able to relate the diseases to the rearing systems , evaluating from the gross features the more suitable diagnosis methods and thus the application of biosecurity, therapy or vaccination protocols.
  In the case of Public Health it should be provided for the student the knowledge regarding:
1) Organization of the National and International Health System;
2) Practical application of some national prophylactic plans (Salmonellosis and Avian Flu)
3) Urban Veterinary Hygiene (Control of Urban Pigeon Population )

The teaching resources related to theoretical lessons are also available on the Unistudium platform
Educational objectives
In relation to Avian Pathology, the student must have acquired, in addition to theoretical knowledge, the ability to move in avian field as a free professional or publicl veterinarian by the visit on farms (control of biosecurity and health status of animal), the acquisition of capabilities in diagnostic and in application of vaccine prophylaxis and/or therapeutic protocols. With respect to Public Health issue the main objective is to provide tools making the student able to the practical application of National Surveillance Plans for Salmonella and Avian Flu.
Prerequisites
Prerequisites provided by the LM 42 Regulation
Since the objective of the course is to provide a comprehensive knowledge of the poultry sector and related Public Health issues , the student must have a scientific background regarding:
1) Nutrition and avian technology (rearing systems) as several diseases are caused by inadequate management ;

2) Anatomy and physiology of birds since several pathologies are favored by their anatomical and physiological characteristics
3) Microbiology and Pathology: the diagnosis on the birds is firstly clinical and anatomic pathological so that the student must be able to identify signs and changes to the various organs and possibly connect them to infectious and not (infectious) causes
Teaching methods
The teaching program is structured in:
33 hours of theoretical lessons,
12 hours of common practical lessons (3 rounds of 4 hours for 4 groups)
4 hours of clinical rotation (1 rounds of 4 hours for 4 groups)
The practice lessons provide :
execution of poultry necropsy for application of diagnostic iterative method (from autopsy to diagnosis) also with the help of slides suggestive for gross pathological changes
Visiting Poultry Facilities (hen and chicken meat farms) and application of Biosecurity precautions and evaluation of health status of animals
Other information
Attendance to seminars on veterinary public health related to the poultry field
Learning verification modality
Oral examination (lasting from 30 to 40 min ) consists of questions on:
1) infectious and parasitic diseases (etiology, clinical, prevention and/or therapy)
2) non-infectious diseases (nutritional, metabolic diseases )
3) Public Health related to poultry (National Surveillance Plan for Salmonellosis and Avian Flu) and the organisation of the National Health Service.
The way, in which the examination is performed, is explained to the students in the first day of lesson.
The goals of the evaluation are to verify :
a) the ability to recognize and describe the lesions through the use of slides;
b) the ability to link the causative agent to the lesion;
c) the ability to make a differential diagnosis;
d) knowledge of the therapy and vaccine plans.
The examination committee, consisting of two professors at least, evaluates the following criteria: the degree of knowledge of the student , and his skill in presentation and ability to create links to other contents of the course program
