Detection of Corynebacterium salmoninus by Direct Fluorescent Antibody Test

Canadian Journal of Fisheries and Aquatic Sciences, 1980
A direct fluorescent antibody test (FAT) was developed for detecting Corynebacterium salmoninus, causative agent of bacterial kidney disease. The direct procedure was found to be as specific as the previously described indirect test, and requires only 7 min—about [Formula: see text] as much time—to perform. A comparison of the direct FAT with the Gram

Specific direct fluorescent antibody identification of Mycobacterium leprae.

International journal of leprosy and other mycobacterial diseases : official organ of the International Leprosy Association, 1976
In vitro cultivation of M. leprae requires a rapid, specific identification procedure for monitoring the cultures. A method utilizing direct FITC-coupled lepromatous, specific serum globulin is described in detail with suggestions for improvement.

Direct and indirect fluorescent-antibody staining techniques using commercial monoclonal antibodies for detection of respiratory syncytial virus

European Journal of Clinical Microbiology & Infectious Diseases, 1989
A comparison was made between direct and indirect fluorescent-antibody staining techniques using commercial monoclonal antibodies for detection of respiratory syncytial virus in respiratory secretions. Overall agreement between the two tests was 94%. Using virus isolation as the reference method, the indirect test had a higher sensitivity but a similar

Specific direct fluorescent antibody detection of Treponema pallidum.

Health laboratory science, 1977
In a study to determine the reliability of specific direct fluorescent antibody staining of Treponema pallidum (DFATP) in lesion exudate, and to evaluate it as a potential diagnostic test to be used in lieu of or as an adjunct to the darkfield and other laboratory tests as an aid in the diagnosis of early syphilis, two types of comparisons were made ...

The use of immunochemically purified anti-brucella antibody in a direct fluorescent antibody test for Brucella abortus

Veterinary Immunology and Immunopathology, 1980
Antibodies specific for Brucella abortus were purified from the serum of hyperimmunized sheep using immunochemical procedures. They were conjugated to fluorescein isothiocyanate and used in a fluorescent antibody (FA) test for B. abortus. The conjugate did not stain any heterologous bacterial or fungal species tested and background fluorescence ...

Examination of Poultry Litter for Salmonellae by Direct Culture and Fluorescent Antibody Technique

Avian Diseases, 1976
Direct culture and fluorescent antibody (FA) procedures were used for examining approximately 6200 samples of poultry floor or nest litter for salmonellae. Each sample was cultured directly in tetrathionate brilliant-green (TBG) broth, incubated at 42 C for 48 hours, and plated on brilliant green (BG) agar.

The direct fluorescent antibody test for the detection of Treponema hyodysenteriae in pigs

Research in Veterinary Science, 1975
A direct fluorescent antibody technique for the detection of Treponema hyodysenteriae in faeces and bowel smears from pigs produced a better preparation than the indirect method and also had the advantages that it took less time, produced less non-specific fluorescnece and gave direct control over the availability of the reagents used.

Usefulness of the Direct Fluorescent Antibody Technique for Diagnosis of Influenza in Swine

Journal of Veterinary Medicine, Series B, 1986
SummaryThe usefulness of the direct fluorescent antibody technique (FAT) for diagnosis of influenza in swine was determined. A total of 171 lung samples from 57 swine (3 samples per animal) were tested with both the direct FAT and virus isolation (VI) in embryonated eggs. A diagnosis of influenza was made in 16 swine.

Kinetics of haloperidol binding to monoclonal antibodies as measured by direct fluorescence quenching

Biochemical Pharmacology, 1992
Monoclonal antibodies which bind small neurogenic ligands may mimic certain aspects of the stereospecific binding present in the natural biological receptor, and may prove useful in designing engineered protein receptors, provided their interactions are correctly understood.

Retrospective examination of lung tissue specimens for the presence of Legionella organisms: comparison of an indirect fluorescent-antibody system with direct fluorescent-antibody testing

Journal of Clinical Microbiology, 1984
Although direct fluorescent-antibody (DFA) testing has been used successfully for a number of years to detect legionellae in clinical specimens, the number of known species and serogroups of Legionella has now increased to such an extent that the performance of DFA testing for all serological variants is impractical.
