Cadaveric dissection is the best method to teach and learn the gross anatomy for that purpose the human cadavers or remains which are stored in tank room or containers in formalin solution, pose a constant hazard of infection to the handlers. Many organisms have been isolated and handlers will be unaware of contamination status of cadaver. Further our I MBBS students who are exposed to such an environment, may be for the first time have chances of acquiring infection. Hence considering the potential health hazard by the cadavers and cadaveric pool in dissection room, we have undertaken a study to know the different types of organisms and their pathogenicity.
