Complement Fixation in Influenza with B. Influenzae Antigens

Studies on the Complement Fixation Antigens of Influenza Viruses Types a and B* by Maria

Allantoic fluids collected from chick embryos infected with the viruses of influenza have been shown to contain at least two types of specific particles which can be separated by differential centrifugation. The larger of these particles possesses a sedimentation constant of between 600 and 800 S (1--4) and is referred to as "600 S component" in the present report. From the sedimentation consta...

Studies on the Complement Fixation Antigens of Influenza Viruses Types a and B

Two types of specific particles can be obtained from allantoic fluid preparations of influenza A and B virus. The larger particle which possesses all the attributes of the virus and which shows a sedimentation constant of about 600 S was compared with the smaller component (30 S) by complement fixation technic. The 30 S component can be differentiated from the 600 S particle by the patterns of ...

A serological comparison of complement fixation reactions using Brucella abortus and B. melitensis antigens in B. abortus infected cattle.

Brucella abortus and B. melitensis antigens were used in parallel on the National Standard Brucella abortus antiserum and on field sera coming from cattle where practically exclusively B. abortus biotypes 1 and 2 have been isolated over the last 11 years. With the National Standard serum the titres to B. melitensis were consistently lower than those to B. abortus antigen. Most were 1 dilution (...

Indirect Complement Fixation in Foot-and-Mouth Disease

Haemophilus Influenzae B

  یکی از شایع ترین مننژیت باکتریایی در شیرخواران، هموفیلوس آنفلوانزا از نوع B (HIB) می باشد. به منظور تهیه و عرضه واکسنی جهت حفظ کودکان در مقابل این بیماری به بازار جهانی، تحقیقاتی انجام و نوعی واکسن در بخش تحقیقاتی آکسفورد مورد آزمایش و ارزیابی قرار گرفت تا در صورت تمایل والدین و کارکنان بهداشتی، تجویز همزمان آن با واکسن سه گانه و فلج اطفال عملی گردد.
