Merkel like-wise elaborates on the biological background of tuberculosis. The concept has also been discussed in class. This disease is caused by a mycobacterium. Mycobacterium was the primary causative agent of tuberculosis back then. Another bacteria called Vibrio cholera is the primary causative agent of cholera. Back then there were no advance medical facilities to deal with these diseases, hence the results of the outbreak used to be even more drastic and worse?...
