Accessory plasma factors involved in the bactericidal test for type-specific antibody to group A streptococci. I. A typical behavior of some human and rabbit bloods

Abstract

The bloods of two apparently healthy human beings, of 25 studied, failed to produce a strong bactericidal test for type-specific antibody to the M protein of group A streptococci under in vitro conditions wherein most human blood leukocytes rapidly phagocytize and destroy virulent organisms in the presence of anti-M antibody and accessory plasma factors. The defect in bactericidal activity of these two individuals is associated with the plasma rather than with the blood leukocytes. Leukocytes suspended in these atypical plasmas showed a characteristic delay in the rate of activation of phagocytosis. Although previously the bloods of laboratory animals (except monkeys) had been reported to be much less active than human blood in this system, occasional exceptions were encountered in rabbits in this study. Two rabbits were found whose bloods were as strongly bactericidal against streptococci, in the presence of type-specific antibody, as the blood of the average "normal" human being. The atypical behavior of some human and rabbit bloods in the bactericidal test may be explained by variations in accessory plasma factors that are as yet unidentified and that influence the rate of phagocytosis of virulent streptococci in vitro in th...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
