There are two kinds of stitches, those which are absorbable (or dissolvable) and will break down harmlessly in the body over time, and those that are non-absorbable (or non-dissolvable) and must be manually removed by the surgeon. There are also different kinds of absorbable sutures, made with different materials. Therefore, after you have had your wisdom teeth removed, or after any kind of oral surgery, absorbable sutures might take from a few days to a few weeks to dissolve completely.
The laboratory diagnosis of pulmonary tuberculosis (TB) and tuberculous meningitis (TBM) is particularly challenging. The aim of the present work is to develop an immunoassay for the diagnosis of TB infection, using synthetic peptides of antigen (Ag) 85 complex of M. tuberculosis (Mtb) H37Rv. Four peptides (7â10 amino acids long) corresponding to group-specific epitopes of Ag 85 complex of Mtb were synthesized.
The invading microbe or pathogen is called an antigen. It is regarded as a threat by the immune system and is capable of stimulating an immune response. Antigens are proteins that are found on the surface of the pathogen.Antigens are unique to that pathogen.The whooping cough bacterium, for example, will have different antigens on its surface from the TB bacterium. When an antigen enters the body, the immune system produces antibodies against it. type of white blood cell called a lymphocyte recognizes the antigen as being foreign and produces antibodies that are specific to that antigen. Each antibody has a unique binding site shape which locks onto the specific shape of the antigen.
