Detection of oral anaerobic spirochetes in dental plaque by the indirect fluorescent-antibody technique [PDF]

open access: yesJournal of Clinical Microbiology, 1979
The indirect fluorescent-antibody technique was found to be a rapid and sensitive tool for the detection of oral anaerobic spirochetes in dental plaque.

Indirect fluorescent-antibody technique for serological diagnosis of La Crosse (California) virus infections [PDF]

open access: yesJournal of Clinical Microbiology, 1982
A clinically relevant indirect fluorescent-antibody technique (IFA) was developed for the serological diagnosis of La Crosse virus infections. The IFA (67%) was as sensitive as the hemagglutination inhibition (58%) and neutralization (58%) tests in the detection of antibodies in acute-phase specimens.

Evaluation of Two Types of Infectious Mononucleosis Antigen Slides by the Indirect Fluorescent-Antibody Technique [PDF]

open access: yesApplied Microbiology, 1973
The efficiency of two types of antigen slides was compared by using the indirect fluorescent-antibody technique. Fifty sera from infectious mononucleosis patients were tested concurrently on the two sets of slides for antibody to Epstein-Barr virus. The indirect fluorescent-antibody serum titer readings from the epoxy slides were either equal to or ...

An indirect fluorescent antibody technique for the diagnosis of Hematodinium sp. infection of the Norway lobster Nephrops norvegicus [PDF]

open access: yesDiseases of Aquatic Organisms, 1996
An indirect fluorescent antibody technique (IFAT) has been developed to detect Hemato­ dinium sp. in the haemolymph and tissues of the Norway lobster Nepiiiops norvegicus. The IFAT, being more sensitive and reliable than previously used field and laboratory diagnostic techniques, detects both lower-level haemolymph infections as well as previously ...

An Indirect Fluorescent Antibody Technique Using Soluble Antigens for Serodiagnosis of Trypanosoma cruzi Infection

open access: yesExperimental Biology and Medicine, 1965
SummaryA soluble antigen fluorescent antibody (SAFA) technic for the serorecognition of American trypanosomiasis is described. The technic has the following advantages over the conventional whole organism indirect fluorescent antibody tests: 1) permits the investigator to objectively select the antigen; 2) provides for mechanical reading of test ...

Comparison between enzyme-linked immunosorbent assay and indirect immunofluorescence for detection of antineutrophil cytoplasmic antibodies

open access: yesEinstein (São Paulo), 2020
Objective To evaluate the performance of enzyme-linked immunosorbent assay and indirect immunofluorescence methods for the detection of antineutrophil cytoplasmic antibodies in a routine clinical laboratory setting. Methods A total of 227 samples were

Indirect Fluorescent Antibody Techniques for Demonstration of Trout Viruses and Corresponding Antibody [PDF]

open access: yesActa Veterinaria Scandinavica, 1974
Two variations of the indirect fluorescent antibody technique (FAT) have been utilized in the work concerning two important virus diseases of trout, viral haemorrhagic septicaemia (VHS) and infectious pancreatic necrosis (IPN). A “two layer” indirect FAT allowed demonstration of the respective viruses in cell cultures and a “three layer” indirect FAT ...

Vigilancia de la infección por Rickettsia sp. en capibaras (Hydrochoerus hydrochaeris) un modelo potencial de alerta epidemiológica en zonas endémicas

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2011
Introducción. Los capibaras o chigüiros (Hydrochoerus hydrochaeris) son huéspedes amplificadores de Rickettsia sp. Usualmente se encuentran parasitados por la garrapata Amblyomma cajennense, principal vector de rickettsiosis en Suramérica.

Comparison of rabies humoral antibody titers in rabbits and humans by indirect radioimmunoassay, rapid-fluorescent-focus-inhibition technique, and indirect fluorescent-antibody assay [PDF]

open access: yesJournal of Clinical Microbiology, 1977
Rabies humoral antibodies were induced in eight New Zealand rabbits by a single intramuscular injection of inactivated suckling mouse brain rabies vaccine. The primary response to immunization was measured in blood samples taken at selected intervals for 6 months.
