Avian Diseases, 1972
Attempts (1,2,4,5) have been made to develop more rapid and accurate methods of detecting avian encephalomyelitis (AE) antibody in chickens in place of the virus-neutralization test (VNT) and embryo-susceptibility test. A fluorescent antibody blocking test (FABT) was recently reported by Davis and Lukert (1).

Detection of Bovine Enteropathogenic Escherichia coli by Indirect Fluorescent Antibody Technique
American Journal of Veterinary Research, 1978SUMMARY Experiments were conducted to evaluate the effectiveness of an indirect fluorescent antibody test (ifat) in detecting bovine enteropathogenic types of Escherichia coli in the feces of young calves with diarrhea. Results in preliminary studies demonstrated that, in tests against stored cultures of bovine E coli, a pooled OK antiserum was ...

Dracunculus medinensis: Diagnosis by indirect fluorescent antibody technique
Experimental Parasitology, 1970Abstract First-stage larvae of Dracunculus medinensis, stored at −78 °C, proved suitable as antigen in the fluorescent antibody technique. Fifty-two samples of serum were obtained from dracunculiasis patients at various intervals after patency; 33 out of the 34 taken up to 6 months after patency gave a positive reaction.

Tropical Animal Health and Production, 1994
An indirect fluorescent antibody (IFA) technique has been developed for detection of anti-Dermatophilus antibodies in sheep. Sera from 25 bacteriologically confirmed clinically affected sheep and from 10 negative non affected lambs were used. Whole cell antigen from brain heart infusion cultures of D.

Indirect fluorescent antibody technique with micro-fragments of Wuchereria bancrofti
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1973Abstract The indirect fluorescent antibody technique, using the actual causal agent as antigen, was evaluated as an immuno-diagnostic test for detecting patients who are sensitive to bancroftian filarial antigen. To achieve the economy in the use of the antigenic material micro-fragments, cut by means of a cryostat, of microfilariae and infective ...

Rubella Antibodies in Human Serum: Detection by the Indirect Fluorescent-Antibody Technique
Science, 1964Antibodies for rubella virus were detected in human serum and titrated by the indirect method of immunofluorescence; a chronically infected, continuous line of monkey kidney cells was used as antigen. Positive reactions were obtained with serums from convalescent patients or persons who had been exposed to the virus while serums from patients in the ...

Evaluation of Indirect Fluorescent Antibody Technique for Detection of Rabies Antibody in Human Sera
The Journal of Immunology, 1963Summary Five hundred and eighty-eight sera were tested by the serum neutralization (SN) and indirect fluorescent rabies antibody (IFRA) procedures. Of 285 positive sera by the SN test, 280 (98.3%) were also positive by the IFRA method, indicating acceptability of the IFRA test as a screening procedure for the detection of rabies antibody.

An Indirect Fluorescent-Antibody Technique for Study of Uncomplicated Gonorrhea. I. Methodology
Journal of Infectious Diseases, 1973An indirect fluorescent-antibody technique was developed for detection of antibodies to Neisseria gonorrhoeae in sera from patients with uncomplicated gonorrhea. The test antigen is a strain of N. gonorrhoeae selected for its stability in the laboratory and for its reactivity with sera from culturally positive females.

Seroprevalence of Ovine Sarcocystosis by Indirect Fluorescent Antibody Technique
UTTAR PRADESH JOURNAL OF ZOOLOGYSarcocystis spp. is a prevalent parasite found in livestock raising significant concerns for public health due to the potential risks associated with the consumption of undercooked or raw meat. Sarcocystis species have been identified in various animals worldwide yet our study marks the first investigation of Sarcocystis infection in slaughtered sheep ...

An indirect fluorescent antibody technique for Haemophilus ducreyi.
Health laboratory science, 1978An indirect fluorescent antibody technique which allows the detection of antibody against or the recognition of Haemophilus ducreyi has been developed. Heat inactivated antiserum was reacted uith prepared smears of Haimophilus species and selected organisms commonly associated with penile ulcerations.
