Evaluation of direct fluorescent antibody test for the diagnosis of bovine genital campylobacteriosis.
The direct fluorescent antibody test (DFAT) for the diagnosis of Bovine Genital Campylobacteriosis was assessed for its detection limit, observer effect, sensitivity and specificity. In addition, the specificity of the fluorescent conjugate was tested against Campylobacter sp, Arcobacter sp, Helicobacter sp, E. coli and other bacteria from the preputial flora. Ten - fold dilutions of C. fetus s...
متن کاملDiagnosis of Intestinal Amoebiasis with Indirect Fluorescent Antibody Test
SUMMARY The results of direct stool examination in 102 watery and bloody diarrhea patients were compared with the presence of antibodies against Entamoeba histolytica with Indirect Fluorescent Antibody Test. Besides 22 healthy individuals included in this study as control group. It was found that 22 patients (21.5%) with a sera titre higher than 1/320 bad only 9 (8.8%) positive E. Histolytica ...
متن کاملComparison of diagnostic tests for the detection of bovine brucellosis in the natural cases of abortion
Rapid and precise diagnosis in natural field cases of bovine abortion caused by Brucella abortus warrants the use of the most sensitive and reliable diagnostic methods. In the present study, bacterial isolation, serology, gross, histopathology, immunohistochemistry and polymerase chain reaction technique(s) were applied. Sero-prevalence studies showed the rate of 28.86% positive cases using the...
متن کاملDetection of Streptococcus mutans in plaque samples by the direct fluorescent antibody test.
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. The fluorescent antibody test (FAT) has been suggested as a potentially simpler method of dete...
متن کاملPassive hemagglutination test for bovine chlamydial abortion.
Purified chlamydial elementary bodies were subjected to sonic lysis to produce soluble antigen for passive hemagglutination (PHA). PHA was more sensitive than complement fixation (CF) in detecting antibody in hyperimmunized rabbits, lambs, and calves. Both CF and PHA tests were used to monitor antibody responses in experimentally infected pregnant cows. All animals responded with rises in titer...
