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 ...

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 ...

Antibodies to specific parasites may be readily detected in eluates of dried bloodstains. The method is based upon the reaction of a serum antibody with an antigen on a microscope slide. The presence of a positive reaction is visualized by fluorescence microscopy after reacting the antigen-antibody complex withfluorescein-labelled anti-human ...

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.

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.

The antibody response of six calves infected with 500 metacercariae of Fasciola gigantica each was monitored throughout 30 weeks of infection using an indirect fluorescent antibody technique (IFA). In vitro excysted F gigantica were employed as the test antigen. All animals showed high antibody titres from two to six weeks post-infection.

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 ...

A procedure is described for the detection of specific antimicrobial antibodies in bloodstains. The technique is described and the relationship between antibody concentration and the age of the doner is reported. It is shown that, provided foetal blood can be excluded, an unknown bloodstain may be identified as that of a person over 15 years with a ...

A technique for detecting antibodies in fish is described that may be of value in screening fish populations for various disease agents. The technique is based on the reaction between fluorescein-labelled antifish globulin and a fish antibody–antigen complex. The immune responses of Pimephales promelas, Notemigonus crysoleucas, and Fundulus grandis to

The use of the indirect fluorescent antibody technique in avian spirochaetosis.
Avian pathology : journal of the W.V.P.A, 2008The indirect fluorescent antibody technique was used for the detection of antibodies to Borrelia anserina in chicken serum. Sera from immunised and convalescent chickens, following experimental infection, gave specific fluorescence, whereas no such reaction could be observed with sera of healthy chickens with no history of the disease.
