A- is lyme disease, dear and tick and something with x in the name
B and C look alike so must be one of those what about B, altough pseudomonas is with wet places

The correct answer is E.
The child has "rat-bite fever." This occurs in two forms with somewhat similar clinical manifestations. The form this child has is the Haverhill fever form, caused by Streptobacillus moniliformis and characterized by a short (often 1-3 days) incubation period. The Haverhill form is more common in the United States than the Sodoku form, which is caused by Spirillium minus, has a 1-4 week incubation period, and is most prevalent in Japan. One of the problems with diagnosing these diseases is that the victims are usually young children, and the bite site may be inapparent by the time the disease becomes severe enough for the child to be taken to a doctor.
Borrelia burgdorferi (choice A) causes Lyme disease, which is characterized by an expanding erythematous rash, arthralgias, and eventual nervous system involvement.
Pseudomonas mallei (choice B) causes glanders, which generally affects horses or humans in close contact with equines.
Pseudomonas pseudomallei (choice C) causes melioidosis, a rare pulmonary disease found mostly in Southeast Asia.
Spirillium minus (choice D) causes the Sodoku form of rat-bite fever.

What I know with Spirillus Minus the rash is less prominent, and it's develops sometimes, compare to Streptobacillus Mon. where rash is very prominent. And yes, it's more in the USA.
