Complement-fixing antibody response to rotavirus infection.
A human rotavirus complement-fixing (CF) antigen, prepared by purification of large volumes of fluid feces collected from children with winter diarrhea, was used to study the development and persistence of antibody in children with diarrhea and the prevalence of rotavirus antibody in Melbourne. In children with diarrhea, antibody rises were detectable within 4 to 6 weeks of the onset of illness...
متن کاملComplement levels in pneumococcal pneumonia.
Levels of complement proteins and functional activity of the alternate complement pathway were assessed in 39 patients with pneumococcal pneumonia. Mean levels of C3 and properdin and the functional activity of the alternate pathway in acute sera were significantly (P less than 0.05) below normal, whereas levels of components of the early classical pathway were normal. Although levels of factor...
متن کاملFixing a Hole: Preventing Pneumococcal Pneumonia by Vaccination
The immune system of the human newborn is capable of responding to every microorganism or one of its components it encounters. In fact that is not true, there is one exception. The immune system of newborns is unable to respond to the capsular polysaccharides of bacteria such as Streptococcus pneumoniae. Because the immune system does not respond, S. pneumoniae can cause diseases such as pneumo...
متن کاملComplement-fixing immunoglobulin M antibody response in patients with infantile gastroenteritis.
Complement-fixing immunoglobulin M antibody to infantile gastroenteritis virus (a rotavirus) was detected with highest sensitivity when the antibody-antigen-complement mixture was incubated at 37 degrees C for 1 h prior to the addition of sensitized sheep erythrocytes. Sucrose gradient centrifugation of sera collected sequentially from four patients after infection detected 19S complement-fixin...
متن کاملWestern blot analysis of antibody response to pneumococcal protein antigens in a murine model of pneumonia.
To detect new antigen candidates for serological tests, we studied the antibody response to pneumococcal protein antigens in mice infected intratracheally with various Streptococcus pneumoniae strains. Sera were tested by Western blotting against whole-cell protein extracts. Mice developed a detectable immunoglobulin G-type response against a small number of polypeptides. The antibody response ...
