Serologic Differentiation of Trachoma Strains and Other Agents of the Psittacosis - Lymphogranuloma Venereum-Trachoma Group with the Aid of the Direct Fluorescent Antibody Method [PDF]
Journal of Immunology, 1965 The serologic relationship of various strains of the psittacosis-lymphogranuloma venereum-trachoma group of agents was examined with the aid of rabbit immune sera and antigens partially purified with fluorocarbon or diethylaminoethyl cellulose.

Detection of Streptococcus mutans in Plaque Samples by the Direct Fluorescent Antibody Test [PDF]
Journal of Dental Research, 1976 Culture methods traditionally have been used to isolate and identify bacterial species in clinical specimens. Culture methods are difficult when the specimen is as bacteriologically complex as dental plaque1 and when the organism in question, such as Streptococcus mutans, is present in modest numbers.

Development and Evaluation of a Direct Fluorescent Antibody Method for the Diagnosis of Pneumocystis carinii Infections in Experimental Animals [PDF]
Applied microbiology, 1973 Because no fully satisfactory diagnostic method has been available for use in pneumocystis infection, an attempt was made to apply the fluorescent antibody technique in the identification of Pneumocystis carinii. Hyperimmune sera were prepared in rabbits

Comparison of PCR, Culture, and Direct Fluorescent-Antibody Testing for Detection of Bordetella pertussis [PDF]
Journal of Clinical Microbiology, 1999 ABSTRACT We prospectively compared the performance of culture, direct fluorescent-antibody testing (DFA), and an in-house-developed PCR test targeting the repeated insertion sequence IS 481 for the detection of Bordetella pertussis in nasopharyngeal swab specimens.
