Extremely high titers of serum antibodies against the streptococcal exoenzyme deoxyribonuclease B.

In sera from 4 of 25,000 individuals tested for antibodies against streptococci, extremely high antideoxyribonuclease B titers ( > 10(6) U/ml) were found. Two of the cases were diagnosed as monoclonal gammopathies. The M-components were shown to possess the anti-deoxyribonuclease B activity. The other two cases were diagnosed as relapsing erysipelas. The high serum titers of deoxyribonuclease B...

High Titers of Hemagglutination Inhibition Antibodies against 2009 H1N1 Influenza Virus in Southern Iran

Background: Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths. Objective: In this study we aim to measure,...

Micro test for streptococcal anti-deoxyribonuclease B.

A methyl green decolorization micro test for the determination of streptococcal anti-deoxyribonuclease B titers in serum is described. The micro test was compared with an alcohol precipitation macro test on 112 human sera. The anti-deoxyribonuclease B titers agreed within one dilution step for 85.7% of the 112 sera examined by both techniques. Both tests were about equal in the detection of tit...

Serum titers of IgG antibodies against tetanus and diphtheria toxoids and risk of multiple sclerosis.

We conducted a prospective nested case-control study among military service members to investigate whether antibodies against tetanus or diphtheria predict multiple sclerosis (MS) risk. Paired T-tests were used to compare means of anti-tetanus and diphtheria toxoids among 56 MS cases and 112 matched controls. Conditional logistic regression was used to estimate odds ratios (OR). There were no d...
