Description: A competitive ELISA for quantitative measurement of Human Platelet antibodies IgG in samples from blood, plasma, serum, cell culture supernatant and other biological fluids. (chipgrade.com)

B pertussis , a gram-negative pleomorphic bacillus, is the main causative organism for pertussis. (medscape.com)

These efforts will enhance the diagnosis and surveillance of agents causing pertussis or diphtheria. (cdc.gov)
The diagnosis of pertussis is made by isolation of B pertussis in culture. (medscape.com)
Pertussis should be included in the differential diagnosis of protracted cough with cyanosis or vomiting, persistent rhinorrhea, and marked lymphocytosis. (medscape.com)

Mice showed similar Hib antibody responses for the combination and HibT alone whereas guinea pigs consistently showed lower anamnestic responses to Hib for combination formulations than for HibT alone. (rostlab.org)

The animals were bled at 4, 6 and 8 weeks and serum samples were tested for antibodies to various components by ELISA, RIA and/or neutralization tests. (rostlab.org)

The lab has also identified antibodies that protect epithelial cells from the deleterious effects of the toxin. (wadsworth.org)
The attraction was predominantly due to I-A-expressing thymic epithelial cells and was mediated by pertussis toxin-sensitive G-protein signals. (ox.ac.uk)

Along with their role as a prophylactic, the antibodies could potentially treat newborns already hospitalized with pertussis, according to Kaleko. (thedailytexan.com)

Bacterial toxins can be single proteins or oligomeric protein complexes that are organized with distinct AB structure-function properties. (springer.com)
G proteins were identified by sodium dodecyl sulfate-polyacrylamlde gel electrophoresis after adenosine diphosphate ribosylation in the presence of pertussis or cholera toxins. (elsevierpure.com)

Laminin-332 polypeptides are targeted by auto-antibodies in human patients with mucous membrane (cicatricial) pemphigoid or, more rarely, subepidermal vesicular diseases that resemble epidermolysis bullosa acquisita (EBA) or bullous pemphigoid (BP). (morulaivf.com)

Bacterial toxins also catalyze the non-covalent modification of host protein function or can modify host cell properties through direct protein-protein interactions. (springer.com)
Bacterial toxins are often characterized based upon the secretion mechanism that delivers the toxin out of the bacterium, termed types I-VII. (springer.com)
This review summarizes the major families of bacterial toxins and also describes the specific structure-function properties of the botulinum neurotoxins. (springer.com)

Western blotting was performed with the use of highly specific antibodies against the following subunits: αG s , αG 1(1 or 2) , αG 1(3) , αG o , αG z and β subunits. (elsevierpure.com)

Description: Quantitativesandwich ELISA kit for measuring Human candida albicans (C.albicans) antibody (IgM) in samples from serum, plasma, cell culture supernates, tissue homogenates. (putyourcolours.pl)

Seroconversion rates for the pertussis toxin were 96.6% after TdaPTgen and 96.0% after PTgen, but only 55.0% after Tdap. (medscape.com)
Tdap contains lower doses of diphtheria and pertussis components (indicated by the lower case d and p ). (msdmanuals.com)

Pertussis can be challenging to diagnose at times because the symptoms that present during the catarrhal stage are frequently indistinguishable from those of a common cold or of another respiratory illness such as bronchitis, influenza, and, in children, Respiratory Syncytial Virus (RSV). (labtestsonline.org.br)
A pertussis culture and/or PCR test will usually be ordered on these patients but should not be performed on close contacts that do not have symptoms. (labtestsonline.org.br)

CDC's pertussis and diphtheria laboratorians and epidemiologists can assist health departments during pertussis outbreaks or when a doctor suspects a case of diphtheria. (cdc.gov)

With rare exceptions B. pertussis infections are restricted to the airways and do not usually disseminate beyond the respiratory epithelium. (frontiersin.org)
Pertussis infections used to be very common in the United States, affecting about two hundred thousand people in epidemics that would occur every few years. (labtestsonline.org.br)
Pertussis testing is used to diagnose these infections and to help minimize their spread to others. (labtestsonline.org.br)

Immunoblot assays using human epidermal extracts and BP180 NC16a domain recombinant protein confirmed the presence of IgG antibodies against BP180 and recombinant BP180 NC16a domain protein. (morulaivf.com)
Moreover, anti-HPV antibodies from the sera of Gardasil and Gardasil+Pt-injected mice showed cross-reactivity with the mouse brain protein extract. (sanevax.org)
