The fertility specialist recommended the rubella vaccine because if the rubella virus is contracted early in pregnancy there is an increased risk of miscarriage or birth defects such as deafness, cataracts, mental retardation, heart defects, liver and spleen damage. There are contraindications related to conceiving within four weeks of receiving the rubella vaccination because it is a “live” vaccine and could still cause complications. 2.

Bacterial conjunctivitis is highly communicable and is easily passed from person to person. 4. Natural defenses that help prevent eye infections include: the blinking reflex, tears, barriers such as the eyelid and orbital septum, presence of leukocytes and Langerhans’ cells also help as defense mechanisms. 5. There are preventative measures that could be taken to prevent the spread of this infection. Such measures are washing hands frequently, disinfecting common areas within the class room and simply educating the students on how the infection is spread. Case 1.5 1. This patient had necrotizing fasciitis caused by Streptococcus pyogenes. The presence of the gram-positive cocci growing in chains is the evidence of Streptococcus pyogenes. To consider the condition to be caused by Clostridium perfringens or gangrene there would need to be gram-positive rod-shaped bacteria obtained from the wound. 2. The below the knee amputation was the best solution for this type of infection because necrotizing fasciitis progresses and spreads rapidly, delaying surgical intervention increases the risk of mortality. 3. This bacterium is generally transmitted through person-to-person contact and sometimes can be found in unpasteurized milk. In this case the transmission was most likely related to the
