VPB 211 PATHOLOGY I (GENERAL/ SYSTEMS) Sem. 03/65 h (45:0:20)

An introduction to veterinary pathology will be followed by instructions on general responses of the body systems to tissue injury which will be discussed under cytopathology, disturbances of circulation, inflammation, tissue repair and immunopathology. The course will also include instructions on disorders of cell growth, neoplasia and the nature and cause of disease. The systemic pathology component included in the course will concentrate on instructions that will deal with the aetiology, pathogenesis, morphological changes and the pathophysiology associated with diseases of the respiratory and cardiovascular systems. The laboratory classes will illustrate the gross and histological changes in topics discussed under general responses and those of the systems, and also focus on post-mortem examination of poultry and domestic animals.

VPB 212 IMMUNOLOGY Sem. 03/48h (30:0:18)

In this course following topics will be discussed. General features of the immune system; innate immunity; phagocytes; complement; antigens; antigenicity; passive and active immunity; T and B lymphocytes; MHC class I and class II antigens; antigen recognition by B and T lymphocytes; structure of antibody and T-cell receptor, natural killer (NK) cells; cytokines; humoral and cellular immunity against pathogens and neoplastic cells; immune evasion by pathogens; immunodiagnosis; molecular diagnostic tools; vaccines and their uses in veterinary medicine; type of vaccines; adjuvants and vaccine failure.

Nematodes: ascarids, strongyloids, stongyles, trichostrongyles, metastrongyles, enoplids, spiruroids, and filarids, Cestodes: anoplocephalids, davaineids, dilepididis, hymenolepidids, teniids, and diphyllids; Trematodes: dicrocoeliids, facioloids, paragonimids, paramphistomes and Schistosomes.

VPB 221 PATHOLOGY II (SYSTEMS) Sem. 04/50 h (30:0:20)

This course encompasses instructions on systemic pathology with emphasis on the aetiology, pathogenesis, morphological changes, and the pathophysiology associated with diseases of the alimentary, lymphoreticular, reproductive, locomotor and urinary systems. The course will also include instruction on dermatopathology, neuropathology and diseases affecting the eye and ear. Laboratory classes will illustrate the gross and histological changes associated with diseases included under the different body systems and also focus on postmortem examinations.

VPB 223 MICROBIOLOGY II Sem. 04/90 h (45:0:45).

Continuation of VPB 213 MICROBIOLOGY I and this covers the following topics. Study of antinobacillus, moraxella, bordetella, mycobacteria, clostridia, anaerobic non-spore forming bacteriods, euobacterium, norcardia, dermatophytes, spirochets, mollicutes, rickettsia and coxiella.
