Analysis of Serology and Phylogeny in Spiroplasma Classification
… they were classified into groups based on serology; however, the recent loss of antisera repositories led to the suspension of the requirement to complete serological analysis. Therefore, Spiroplasma taxonomy needs to transition from serology to DNA characters for species circumscription. …

Laboratory investigation of low positive and discrepant HIV serology results
In our diagnostic virology laboratory, we test on average 1500 samples for HIV antibody/antigen each month, of which 0.6% produces problematic results. These problematic samples produce either weakly reactive screening and confirmatory results or, discrepant screening and confirmatory results. Both …

Rabies serology: relationship between assay type, interpretation, and application of results
… management. The reasons for performing rabies serology can range from diagnosis of infection to investigation of epitope specificity of an anti-rabies virus glycoprotein monoclonal antibody. Characterization of an antibody’s affinity, specificity, quantity, and neutralizing function, and …

Insights on Serology, CRISPR Diagnostics, and Machine Learning Architectures for Biological Sequences
Fueled by technological breakthroughs, advancements in our understanding of infectious agents offer unprecedented potential for their early detection, intervention, and ultimately, eradication. This dissertation focuses on combining cutting-edge immunological, diagnostic, and computational …

Development of confirmatory testing strategies for suspect false PRRS-positive reactors in diagnostic serology
<p>The commercial ELISA kit (IDEXX HerdChecky PRRS) has been the main serodiagnostic tool for PRRS virus (PRRSV) in North America and many pig producing regions throughout the world. Although the kit has been mostly a reliable test for detecting PRRSV exposure at the herd level, the specificity of …

Purification, serology and pathogenic role of the 110 kilodalton rtx hemolysins of Actinobacillus pleuropneumoniae
<i>Actinobacillus pleuropneumoniae</i> is the etiological agent of contagious swine pleuropneumonia, an economically important disease of the swine industry worldwide. Improved control of this disease requires enhanced understanding of the factors contributing to pathogenesis. The objectives of …

Maize Dwarf Mosaic Virus in Zea Mays L.: Inheritance of Resistance, Yield Loss, Serology, and Seed Transmission
The effect on sweet corn yield of inoculation with maize dwarf mosaic virus (MDMV) at the three-leaf, eight-leaf, or just prior to silking was examined. Early infection delayed maturity, reduced yield and plant height. Little difference was found between the late inoculation and the inoculated …

Comparative Serological and Molecular Analysis of Group VIII <em>Spiroplasma</em> from Australia and North America
… <em>Spiroplasma</em> have been classified by serology. Recent work has generated 16S rDNA sequences that generally correlate with the serological findings. Although the serology and the 16S rDNA sequence analysis clearly classifies strains to the group level, they do not distinguish between …

Diagnosis of Bovine Anaplasmosis Using Anaplasma Antigenic Markers Identified by Western Blotting
Diagnosis of bovine anaplasmosis relies on serology using crude parasite extracts, detection of parasitemia, or subinoculation of blood from suspected animals into susceptible animals. Anaplasma can not be cultured in vitro. The feasibility of using antigenic markers detected by Western blotting …

The clinical utility of tissue polymerase chain reaction, tissue culture, and tissue histology in blood-culture negative infective endocarditis - a South African single hospital experience
… there was no set protocol for performing serum serology, and the treating clinicians determined empiric antibiotic regimens. Results. During the study period, we identified 165 IE cases, 57 (34.5%) of which were blood-culture negative. BCNIE patients had a mean age (±standard deviation) of 40.2 …

Development and clinical performance of nucleic acid amplification techniques for the diagnosis of Strongyloides stercoralis
… intermittent larval excretion of the parasite. Serology (enzyme-linked immunosorbent assay) suffers from a lack of specificity because Strongyloides antibodies are known to cross- react with schistosomal, filarial and other helminthic antibodies in serological tests. Moreover, antibody levels …

Studies of the Falls Creek (Texas) strain of relapsing fever spirochetes: Part I. Epidemiological and ecological studies. Part II. Serological studies of the "ticktorium" strain of Borrelia recurrentis var turicatae
A semi-micro method, for studying the serology of relapsing fever spirochete infections in small animals, has been described. Spirochete immobilization (spirochaeticidal activity) has been established as the best of the various antibody phenomena to utilize in studying the serology of Borrelia …
