Please make the following correction to the key that was sent out with the 1998-1999 compiled virology examination.

99-70 is listed as B, after further consideration, I think that C might also be a valid choice (but I still do not think either B or C are “correct”). I think the best answer for an unknown, unsegmented (single piece), negative-sense RNA virus associated with respiratory disease would be the family Paramyxoviridae, but this is not a choice. Both Bunyaviridae (B) and Othomyxoviridae (C) are SEGMENTED, negative-sense RNA viruses. Both families include viruses associated with respiratory pathology (influenza virus for Othomyxoviridae and sin nombre virus for Bunyaviridae. Therefore, I can come up with equal justification for either B or C. B was the answer marked on the original 1999 exam that I have.

98-72 is listed as B, it should be A.
Nothing complicated -- just a typo -- sorry.

98-73 is listed as A, I think it should be B.
A was the answer marked on the original examination that I have. I disagree. Smallpox disease has been eradicated. Other diseases caused by poxviruses have not been eradicated.

Hope your studying is going well.

Can I get some opinions about one of the bacteriology questions?

In the CLOSTRIDIUM (C.Perfringes) section, #7 doesn't make sense to me...I don't really understand what it asked, but I don't think C. Perfringes type A or C makes any sort of neurotoxin. But C. tetani and C. botulinum do. Any ideas, comments?

Well, if anyone is still interested, I found the answer to the above question. C. botulinum has 8 neurotoxins and C. tetani has just one. C. perfringes has none.

So, the correct answer is actually E (C. tetani) for number 7-98 in the Clostridium section.
