Measles Pictured above is the Rubeola virus, which causes measles. From this Gram-stain, we can conclude that the virus is Gram-negative by it’s pink color, and rod shaped. (16)

measles 2Here we see one of the physical effects of the Rubeola virus. A patient develops these welts after approximately 8-12 days of infection. (16)

smallpox 2 This is the smallpox-causing Variola major or minor virus. (3)

smallpoxPictured above is a smallpox patient whom has developed pussy lesions severely on his face, hands, and chest. From this picture, we can tell that the patient has been infected with the Variola major or minor viru for at least 12-17 days. (1)

tbA Gram-stain of the Mycobacterium tuberculosis microbacterium is shown, which causes tuberculosis. From this image, we can identify this microbacterium as Gram-negative and rod-shaped in nature. (9)

syph2Pictured above is the secondary stage of Treponema pallidum. In this stage, the patient has overcome the rash on the genitalia, and is experiencing lesions elsewhere on the body. (13)

typhoidHere, we see a Gram-stain of the Salmonella typhi virus, which causes typhoid fever. We cannot determine the shape of the virus, but it is clearly pink-red, meaning it is Gram-negative. (15)

diarrhea Shown in the image above is a microscopic view of a bacterium that causes dysentery, which is rod-shaped. (5)

pneuThis is a negative microscopic image of the pneumonia-causing Streptococcus pneumonia bacteria. This bacterium is rod-shaped and has a cluster characteristic. (17)

pneu2Pictured here is an animated image of lungs after being infected with Streptococcus pneumonia. The lungs are weak and shriveled, and do not work to their full capacity. (14)
