Module overview

This module introduces the student to the general principles of infectious disease and its pathology as well as the host response to infection and infectious disease agents. The cellular and tissue changes induced by infection and or invasion by viruses, bacteria, parasites, fungi and prions will be introduced. These topics will be presented in the context of One Health and underpinned with clinical case examples introducing clinical pathology results from the various veterinary species.

Module aims

Introduce the terminology of infectious disease, the broad categories of infectious agents, systemic pathology based on aetiopathogenesis, and gross and microscopic appearance of lesions induced by pathogens and the host response.

Increase the students' ability to describe pathological findings and write meaningful reports using the appropriate methods and terminology

Module content





Infectious Pathogens: General introduction. The epidemiological triad of infection. Invasion and infection.  




Pathogenesis of infectious agents. General aspects




Bacteria. Major bacterial groups and phenotypical differences




Bacteria and the alimentary system – commensals versus pathogens




Bacterial genetics and virulence factors




Bacterial pathogenesis: colonisation and tissue invasion




Anti-microbial resistance




 Viruses- Taxonomy and genetics.




Unique structures of infectious pathogens – Bacterial LPS, Peptidoglycans, bacterial DNA, Viral Nucleic Acid etc




Parasites. Taxonomy, life cycles and management of the environment of Nematodes, Cestodes, Trematodes, Protozoa, Ectoparasites




Invasion to where and by what route? Extracellular and Intracellular pathogens




Host barriers to infection: Skin and Mucosa




Cells and tissues of the immune and haematopoetic system




1st line of defence: Innate Immunity- recognising Invaders (PAMPs/ DAMPs/ Toll-like receptors)




1st line of defence: Innate Immunity – key cells and phagocytosis




1st line of defence: Innate immunity – the complement system




Immunological cell signals: Cytokines and their receptors




Antigens and MHC complex




Adaptive immune response: T-cells and antigen recognition (TCR)




Antigen presenting cells – bridging the innate and adaptive immune response




T-cell subsets and function and the difference in animal species




Antibody structure and function




B-cells – antigen recognition and antibody production




The orchestra of T-cell and B-cell activation




Regulation of adaptive Immune responses




Immune responses to bacteria, fungi, helminths and viruses




Vaccination principals




Practicals




Collecting appropriate samples to detect infectious pathogens – 1 hour




 




Bacterial culture and identification – gram stains, various light microscopy techniques, dark field – 1 hour




Virus culture and identification - 2 hours




Identifying ectoparasites – gross specimen demonstration and life cycle charts – 1.5 hours




Identifying endoparasites – gross specimen demonstration and life cycle charts – 1.5 hours




Identification and quantification of parasites through faecal examination – 1.5 hours

 




Anti-microbial resistance and LAMP – 2 hour




Immunoassays and ELISAs – 2 hours




PBL cases (6 hours)





 

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

·         Provide infectious disease pathology in the context of One health, One medicine

·         Allow students to develop skills in performing a post mortem examination and identify lesions induced by infectious agents

·         Provide students with the skills to write a meaningful post mortem report and record their findings with appropriate terminology and supporting images

The learning and teaching methods include:

·         Lectures, flipped classroom, small group sessions, PBL cases, practical classes using microscopy and anatomic pathology specimens

 

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

·         Practical skills in performing a post mortem examination

·         Record writing ability and understanding and use of terminology

·         Encourage teamwork and participation in-group learning both in the practical sessions and in the PBL cases.

·         Content knowledge of general pathology and disease mechanisms

Thus, the summative assessment for this module consists of:

·         Formative assessments: Instructor and peer assessments 0%

·         PBL assessment – 10%

·         Practical reports – 10%

·         Steeplechase - 30%

·         Written examination – 50%

Formative assessment and feedback

Formative assessments: Instructor and peer assessments 0%
