Complement in human diseases: Lessons from complement deficiencies.

Evaluation of Pasteurella multocida serotype B:2 resistance to immune serum and complement system

Members of gram-negative bacteria family Pasteurellaceae, include a large number of important economically human and veterinary pathogens. Organisms belonging to the family can colonize in mucosal surfaces of the respiratory, alimentary, genital tracts and cause diseases in various mammals, birds, and reptiles. Hemorrhagic septicemia is an acute disease of cattle and buffaloes in tropi...

Inherited Classical and Alternative Pathway Complement Deficiencies in Children: A Single Center Experience

Complement factors in Acute Myocardial Infarction and Unstable Angina

Background: Coronary artery disease (CAD) is one of the most important and lethal diseases in the world. CAD represents a board spectrum of disease from silent ischemia at one end to sudden cardiac death at the other end. The middle of this spectrum consists of acute myocardial infarction (AMI) and unstable angina pectoris (UA). Recent data show that the inflammatory process plays a major r...

Human genetic deficiencies reveal the roles of complement in the inflammatory network: lessons from nature.

Complement component C5 is crucial for experimental animal inflammatory tissue damage; however, its involvement in human inflammation is incompletely understood. The responses to gram-negative bacteria were here studied taking advantage of human genetic complement-deficiencies--nature's own knockouts--including a previously undescribed C5 defect. Such deficiencies provide a unique tool for inve...

Characterization of complement activity in serum of the four sturgeon species, Acipenser stellatus, A. baeri, A. nudiventris and Huso huso (Chondrostei: Acipenseridae)

Serum complement is valuable tool in determining the health status of fish. This study was conducted to examine in vitro activity of serum complement as an indicator of innate immunity in four sturgeon species, Acipenser stellatus, A. baeri, A. nudiventris and Huso huso (Chondrostei: Acipenseridae). The Effects of different temperatures, concentrations and volumes of serum on alternative comple...
