Antibody Response to Bacterial Antigens: Characteristics of Antibody Response to Somatic Antigens of Salmonella typhimurium.
The character of the antibody response in the rabbit to Salmonella typhimurium somatic (O) antigen was similar to the response to each of several serotypes of Shigella flexneri O antigens, namely a predominance of production of immunoglobulin M (IgM) antibody. Lipopolysaccharide protein (LPSP) and lipopolysaccharide (LPS) fractions of Salmonella O antigen differed significantly in both quantita...
متن کاملAntibody response to glycan antigens of hydatid cyst fluid, laminated layer and protoscolex of Echinococcus granulosus
Background: Hydatid disease is characterized by long-term growth of hydatid cysts in the human. The glycan antigens have an important role in the immunology of hydatid cyst. In this study immunological reaction of host sera to different glycan antigens of the cyst, has been investigated. Methods: The antibody responses were tested to glycoprotein and glycolipid of the laminated layer (LL), c...
متن کاملLeaky RAG Deficiency in Adult Patients with Impaired Antibody Production against Bacterial Polysaccharide Antigens
Loss of function mutations in the recombination activating genes RAG1 and RAG2 have been reported to cause a T-B-NK+ type of severe combined immunodeficiency. In addition identification of hypomorphic mutations in RAG1 and RAG2 has led to an expansion of the spectrum of disease to include Omenn syndrome, early onset autoimmunity, granuloma, chronic cytomegalovirus- or EBV-infection with expansi...
متن کاملAntibody response specific to the capsular polysaccharide is impaired in Streptococcus suis serotype 2-infected animals.
Streptococcus suis serotype 2 is an extracellular encapsulated bacterium that causes severe septicemia and meningitis in swine and humans. Albeit crucial in the fight against encapsulated bacteria, the nature of the capsular polysaccharide (CPS)-specific antibody (Ab) response during S. suis type 2 infection is unknown. We compared for the first time the features of CPS-specific versus protein-...
متن کاملAntibody response against hydatid fluid, protoscolex and whole body of Echinococcus granulosus antigens in lambs
In this study, the immunogenicity of three types of antigens (hydatid fluid, protoscolices and whole body of E. granulosus) was investigated in lambs by ELISA. Sixteen 4–6-month-old lambs of mixed sexes were divided into 4 groups of 4 lambs (three immunized and one control group). Twelve lambs as immunized groups received 2 mg of hydatid fluid, protoscolices and whole body of E. granulosus ant...
