52. A child comes in with crusty lesions all around his mouth.  There are some pustules, but most have oozed and crusted over.  A gram stain is done. What do you expect to see under the microscope? What is the likely disease that this child is suffering from? How did he get it? (Use proper terminology regarding transmission means, morphology, arrangement and possible genus & species.)   A patient comes in for a dental cleaning. The enamel of her teeth is eroded.  The roots are exposed and there is a visible biofilm in the crevices.  She seems to have some difficulty breathing.  Her history states that she has a heart murmur. What disease is occurring in her oral cavity? Is it treatable? If so, how? If not, why not? What other items should you take into consideration when treating this patient? Why?
