Abstract Rabies neutralizing antibody levels were determined in 143 human serum samples by applying a direct fluorescent-antibody test to BHK-21/S13 cells treated previously with dilutions of the test samples mixed with constant amounts of challenge virus.

Examination of Poultry Litter for Salmonellae by Direct Culture and Fluorescent Antibody Technique
Avian Diseases, 1976Direct 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.

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

Journal of Milk and Food Technology, 1975
A comparison of various cultural methods for use with microcolony and direct fluorescent-antibody (FA) techniques to detect salmonella was conducted using 102 naturally contaminated samples. The methods were: (a) a 27-h microcolony technique, (b) a 51-h selenite-F FA microcolony technique, (c) a 51-h tetrathionate brilliant green FA microcolony ...

Abstract Experiments were conducted to evaluate the sensitivity and specificity of a direct fluorescent antibody technique (DFAT) in detecting bovine enterotoxigenic Escherichia coli possessing the K99 adherence antigen. A monospecific K99 antiserum was tested by DFAT against K99-positive and negative control strains and against faecal smears from ...

Journal of Aquatic Animal Health, 1994
Abstract Staining trials were conducted over a 5-year period to explore ways of improving the direct fluorescent antibody technique for Renibacterium salmoninarum (Rs). In most salmonid kidney tissue smears that were pretreated with the organic solvent xylene, acetone, or methanol for 2 min, Rs had substantially higher fluorescence intensity and better
