A clinical study is performed to document complications following upper respiratory tract infections with group A beta hemolytic streptococci, compared to a control group of patients with paramyxovirus infection. It is observed that 2 to 5 weeks following initial infection, some persons with the prior streptococcal infection developed fever, with laboratory studies showing an elevated antistreptolysin O and anti-DNAse B titer. Which of the following abnormalities is most likely to appear in the control group?
A Carditis
B Glomerulonephritis
C Erythema marginatum
D Migratory polyarthritis
E Sydenham's chorea
Answer and explaination please?

well i will go with B) glomerulonephritis (GN) cuz rest are jones' criteria of rheumatic fever cause by strep. Although strep also causes GN. but question is about complication of control group (paramyxovirus which includes parainfluenza and RSV). i may be wrong, i am just picking GN just cuz its not part of jones criteria. u can give the real explanation :|

I thought the same way u did.
The explaination given was:
(B) CORRECT. Strains of streptococci which cause acute rheumatic fever are not the same as the strains which can produce a post-streptococcal glomerulonephritis
