he Department of Medicine was founded in 1984 by splitting the Department of Medicine and Surgery, which was established in 1961. A total of 24 qualified teaching staff served the department since its inception and 10 are currently involved in teaching veterinary students, providing preventive, clinical, and advisory services. Teaching discipline includes both clinical and population medicine, epidemiology of animal diseases especially zoonoses. The Department offers a total of 15 courses (27 credits) in the under-graduate DVM degree program, two courses in BSc AH degree, and one course in BSc Food Security degree. It also offers Masters and PhD degree programs. Since the establishment of this Department, 78, 112, and 13 students obtained MSc, MS, and Ph.D. degrees, respectively. Currently, seven Ph.D. and 32 MS students are enrolled in the Department.

Research facilities already built in the department include serological/cultural and molecular diagnosis of infectious diseases like mastitis, brucellosis, tuberculosis, cryptosporidiosis, giardiasis, rotaviral infection, infectious bursal disease, Newcastle disease, salmonellosis, etc. A total of 32 professional books were published by the teachers of this department. The teaching staff is involved in estimating hierarchical true prevalence and risk factors of animal diseases, evaluating diagnostic tests using Bayesian latent class analysis, conducting training programs for veterinary surgeons involved in animal health research and disease management, health data collection and analysis, application of GIS in veterinary medicine (e.g., risk/disease mapping) etc. The teaching staff of the department has published research articles in several peer-reviewed high impact journals such as Microbial Drug Resistance, Foodborne Pathogens and Disease, Preventive Veterinary Medicine, Veterinary Record, Small Ruminants Research, Frontiers in Immunology, PLoS ONE, PLoS Neglected Tropical Diseases, Parasites & Vectors, Frontiers in Veterinary Science, Transboundary and Emerging Diseases, BMC Veterinary Research, Epidemiology and Infection, Zoonoses and Public Health, BMC Genomics, Veterinary Immunology and Immunopathology, Cytokines, Gene, Veterinary Microbiology, Frontiers in Microbiology, Microorganisms, Beneficial Microbes, Probiotics and Antimicrobial Proteins, Pathogens, Vaccine, Cells, Antimicrobial agents and chemotherapy, Journal of American Veterinary Medical Association, etc. With the collaboration of the Bangladesh Agricultural University Extension Centre (BAUEC) and BAU Veterinary Teaching Hospital (VTH) the department offers herd health services like strategic deworming and vaccination programs.

Ongoing research activities of the department are centered on the epidemiology, diagnosis, and treatment of animal infectious diseases like mastitis, brucellosis, tuberculosis, FMD, PPR, LSD etc., antimicrobial resistance, immunobiotics and alternative medicine, photodynamic therapy, and animal welfare. Ongoing research projects include- the exploration of antimicrobial resistance genes in bacterial isolates from red meat of cattle; exploring effective treatment strategies for brucella-infected cows; optimization of cut off values for somatic cell count for the diagnosis of bovine subclinical mastitis; estimation of risk factors and animal welfare issues associated with mastitis and lameness; production and evaluation of anti-PPR sera against Peste des Petits Ruminants in goats; Innate immune responses in the PBMCs after FMD vaccination in cattle; and epidemiological investigations on lumpy skin disease outbreaks in cattle. The department has active collaboration with Sapporo Medical University, Japan; Ghent University, Belgium; Center for Animal Welfare, University of Queensland, Australia; University of California Davis, USA; The University of Sydney, Australia; University of Thessaly, Greece; Chonbuk National University, South Korea; Bogor Agriculture University, Indonesia; Reference Centre for Lactobacilli (CERELLA), Tucuman, Argentina; and Tohoku University, Japan.
