Learning unit contents

The purpose of the course of Veterinary Bacteriology will consist in the acquisition of skills related to the understanding of bacteria as a microorganism and will prepare students for the understanding of bacterial diseases for the master.
The course will begin with an introduction to veterinary bacteriology in a "One Health" context and will present the diversity of the bacterial world. The course will present the different aspects of bacterial biology (morphologies, metabolisms, multiplication, genetics), bacterial virulence, bacterial defenses, diagnostic methods, treatments, prophylactic measures, resistance to antimicrobial agents and credible alternatives.
Practical lessons in bacteriology will be closely related to the ex-cathedra course. They will illustrate the biology of the bacteria via the different stages of classical bacteriological diagnosis (sampling, inoculation, staining, identification, antibiogram, interpretation of results) allowing, among others, the study of the metabolism, growth and biochemical profiles.

Learning outcomes of the learning unit

Description of the infectious agents that the bacteria are, in general, in animal health and in public health, and of the physico-chemical and biological tools important in the fight against bacterial pathogens. Introduction of the students to the routine diagnosis in laboratories, so that he/she can understand during the final three years of study and during his/her professional life the work performed in these routine diagnostic laboratories.

Prerequisite knowledge and skills

Basic knowledge of eucaryote cytology and biochemistry.

Planned learning activities and teaching methods

The lectures comprise 24h ex-cathedra with a PwPt presentation with an on-line acess on eCampus (with the exception of some ilustrations). When possible, examples from the veterinary field are presented to complete the information.
The laboratory sessions comprise 10 h of practicals (TP) and 2 hours of seminars (TD) during te practicals. These laboratory sessions introduce the procedure of a diagnostic laboratory. 
During the practicals (4h on Monday, 4h on Tuesday, 2h on  Thursday, and 2h on Friday aternoons), the students are demonstrated and perform themselves the different steps in a bacterial diagnosis: sampling, inoculation onto agar plates, staining, identification, antibiotic sensitivity, interpretation and answer to the practitioner. The precise content of each afternoon is adapted each year in function of the number of students present. Prerequisites are on the practical booknote (present on eCampus). General information will be communicated to the students durig one of the lectures. The precise timing is communicated to the students at the beginning of the academic year. 

The students are continuously assessed during the week (general and specific behavior). Moreover, at the beginning their first lab session (Monday afternoon), the students must answer QROC questions on the pre-requisites. During the whole week, the students are invited (i) to fill in on-line (eCampus) a report to present the realization and the understanding of the manipulations and (ii) to ask any question about the lectures and the practicals to the assistant professors, to prepare the practical interrogation of the Friday.
NB: In case of necessity (another day off during the week for instance), one session of practicals will be organized during the Wednesday afternoon of the same week, in order to maintain an acceptable timetable for everybody.

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face course

Additional information:

The 24h of ex-cathedra lectures take place face-to-face in presence of the students in one lecture room. The laboratory sessions (TP and TD) are organized in smaller groups of students in one room dedicated to bacteriological practicals. This room is classified biosafety level 2: it is therefore strictly FORBIDDEN to eat or to drink and students MUST wear a lab coat.
ATTENTION: presence during the TP/TD is COMPULSORY. Any non-justified absence (with an official document) automatically means failure in January. If the student does not contact the person in charge of the organization of the TP/TD, this unjustified absence may even mean failure in September and for the year for the Bacteriology course.
All lectures, TP and TD will be finished during the first quadrimestre, so that the exam can be planned in January.
NB: according to the evolution of the COVID19 pandemia, of the governemental and university recommendations, the mode of delivery of the lectures and of the practicals will be adpated, if necessary.

Recommended or required readings

The students' notes (lectures + practicals) are available on eCampus as are the Power Point presentations (without the figures). The students' notes are adapted each year.

Exam(s) in session

Any session

- In-person

written exam ( multiple-choice questionnaire, open-ended questions )

Out-of-session test(s)

Additional information:

FOREWORD: it is today possible for a student to send an email to the professor (damien.thiry@uliege.be) telling his/her decision to not take the exam. This message has the value of a signature, under two conditions: (i) it must be sent par the student him/herself; (ii) it must be received within 30 minutes after the beginning of the exam (at the latest). Any message received after this delay will not be valid !

The students will be evaluated as follows, once again Covid19 pandema permitting:

- Theory (75% of the final mark) during either session. The format of the theoritical exam of the second session will be identical to the format of the first session.

(a) a multiple choice questionnary (QCM: 25% of the final mark): 20 questions with correct answer +1, wrong answer -0,2, no answer 0; on the contents of the lectures and of the practicals.

(b) a short open-answer-questionnary (QROC: 25% of the final mark): 20 questions with correct answer +1, wrong answer -0,2, no answer 0; on the contents of the lectures and of the practicals;

(c) one long open-answer-questions (QROL: 25% of the final mark).

- Practicals (25% of the final mark). The practcal exam is slightly different between the two sessions.

(a) during the first session, on the Monday afternoon there will be one theoritical interrogation (QROC) on the prerequisites, and on the Friday afternoon there will be theoritical and practical interrogations (QROC, biotyping, antibiogram).

(b) if the practical mark is 10 or higher, it also counts for the 2nd session (if necessary), but not if the student must repeat his/her year. If the practical mark is under 10, the student must take again all the written interrogations the day of the exam during the second session (QROC, biotyping, antibiogram).

Reminder: any non-justified absence at the TP/TD during the year means refusal to present the theoritical exam.
