Evaluation of the comparative accuracy of the complementfixationtest, Western blot and five enzyme-linked immunosorbent assays for serodiagnosis of glanders. Glanders is a zoonotic contagious disease of equids caused by Burkholderia (B.) mallei. Serodiagnosis of the disease is challenging because of false-positive and false-negative test results. The accuracy of the complementfixationtest
Bayesian Validation of the Indirect Immunofluorescence Assay and Its Superiority to the Enzyme-Linked Immunosorbent Assay and the ComplementFixationTest for Detecting Antibodies against Coxiella burnetii in Goat Serum Although many studies have reported the indirect immunofluorescence assay (IFA) to be more sensitive in detection of antibodies to Coxiella burnetii than the complementfixationtest (CFT), the diagnostic sensitivity (DSe) and diagnostic specificity (DSp) of the assay have not been previously established for use in ruminants. This study aimed to validate the IFA by describing the optimization, selection of cutoff titers, repeatability, and reliability as well as the DSe and DSp of the assay. Bayesian latent class analysis was used to estimate diagnostic specifications
Development of a Sterne-Based ComplementFixationTest to Monitor the Humoral Response Induced by Anthrax Vaccines Anthrax is a zoonotic disease caused by Bacillus anthracis spore-forming bacterium. Since it is primarily a disease of animals, the control in animals, and humans depend on the prevention in livestock, principally cattle, sheep, and goats. Most veterinary vaccines utilize for an effective anthrax surveillance. In this study, we developed a Sterne-based ComplementFixationTest (CFT) to detect specific antibodies induced in animals vaccinated with Sterne 34F2. We assessed its efficacy in laboratory animals and under field conditions by monitoring the humoral response induced by vaccination in cattle. The results indicated that the Sterne-based CFT is able to correctly identify
ComplementFixationTest: An Update of an Old Method for Diagnosis of Bullous Pemphigoid. The complementfixationtest (CFT) is a method traditionally used for diagnosis of gestational pemphigoid. Its performance in diagnosis of bullous pemphigoid (BP) has not been investigated in a large patient cohort. The aim of this single-centre, retrospective, serological case-control study of 300 patients

in sera from cattle. The developed ciELISA was validated using 2833 serum samples from dairy and beef cattle. From these, 1515 sera were from uninfected cows that belonged to free of brucellosis herds and 1318 were from infected cows that belonged positive to brucellosis herds. Sera were analyzed with the developed ciELISA, the buffer plate antigen (BPA) test, and the complementfixationtest (CFT
animal products (90.0%). Accordingly, 149 blood samples from animal owners and 17 farmworkers were collected for serological testing. The serum samples collected were initially screened using the Rose Bengal Plate test, and the ComplementFixationtest was used as a confirmatory test. The overall seroprevalence of zoonotic brucellosis was 1.2% (95%CI: 0.32-4.27). There was a statistically significant

He was a farmer with diabetes mellitus, and had a history of close contact with sheep, which might result in C. pecorum infection. Our report could provide a direction for the diagnosis and treatment
Blood tests There may be raised WCC or (rarely) evidence of haemolytic anaemia. ESR may be elevated. Serology titres and complementfixationtests/ELISA can help to confirm the diagnosis. FBC may show left shift. Severe cases may have DIC evident on FBC/INR. Hyponatraemia may occur due to syndrome

By whole cell antigen complementfixationtests (CFT) and ELISA, chlamydial seropositivity was significantly higher in all groups, suggesting cross-reactivity between these two chlamydial species and non-specificity of the tests.

We demonstrate how, despite the high vaccination coverage of the small ruminant population in Israel, our results proved to be effective in discriminating between vaccinated and infected animals.

Using multistage sampling, serum samples of 2409 sheep from 274 flocks were collected and tested using the Rose Bengal Plate Agglutination Test (RBPT) and positive sera were confirmed using a ComplementFixationTest (CFT). Of all animals tested, 4.98% were RBPT positive, and after confirmation with CFT, the overall animal-level prevalence was found to be 4.89% (CI: 3.24-6.9%). Of the flocks

Thin and thick blood smears were used to diagnosis malaria. Out of 630 sera screened by DCAT, 83 (13.2%) were reactive to H and/or O antigens for S. Typhi infection. Among these, 46 (55.4%) were reactive
