The use of the immunoperoxidase monolayer assay (IPMA) has been limited to challenge model investigations10–11 and a few field studies. Guedes et al12 reported 100% specificity and 89% sensitivity at a serum dilution of 1:30 for the IPMA serological test. Guedes et al13 also determined that there was 98.6% agreement between the IFAT and the IPMA tests in experimentally infected pigs, concluding...
Visceral leishmaniasis (VL) is a zoonotic disease caused by leishmania species. Dogs are considered to be the main reservoir of VL. A number of methods and antigen-based assays are used for the diagnosis of leishmaniasis. However, currently available methods are mainly based on direct examination of tissues for the presence of parasites, which is highly invasive. A variety of serological tests ...
Serological tests were performed on 380 cats with necropsy-confirmed heartworm disease to compare the performance of currently available commercial laboratory and point-of-care heart-worm serological tests in a heartworm-endemic area. Overall, antigen tests detected 79.3% to 86.2% of heartworm infections and were highly specific. Most cats with false-negative antigen tests had a single male wor...
BACKGROUND Celiac disease is an immune-mediated inflammation of the small intestine caused by sensitivity to dietary gluten in genetically sensitive individuals. OBJECTIVES In this study, we aimed to evaluate the predictive value of tissue transglutaminase (tTG) antibodies for the diagnosis of celiac disease in a pediatric population in order to determine if duodenal biopsy can be avoided. ...
Leptospirosis is a zoonosis caused by pathogenic bacteria of the genus Leptospira. This disease affects several animals and humans. Symptoms leptospirosis can range from mild to severe, may in some cases lead death. For diagnosis leptospirosis, microscopic agglutination test considered “gold standard”; however, it has limitations studies are being conducted develop alternative methods screening...

The diagnosis of visceral leishmaniasis (VL) remains challenging, due to the limited sensitivity of microscopy, the poor performance of serological methods in immunocompromised patients and the lack of standardization of molecular tests. The aim of this study was to implement a combined diagnostic workflow by integrating serological and molecular tests with standardized clinical criteria. Betwe...
in a comparative study, 460 serum samples were tested for the serological determination of human immunodeficiency vrius (hiv) using an elisa kit and a rapid test kit. results indicated that the rapid test is reliable for screening unkonwn samples when there is no special equipment for screening with immunoblotting and/or elisa.
