A new latex agglutination test for rubella virus was used to test sera with a hemagglutination inhibition titer of -8 (97 specimens) or >256 (158 specimens). Maximum latex agglutination test sensitivity was achieved when low-titer sera were tested undiluted and high-titer sera were diluted (1:10). A modification of the protocol of the manufacturer resulted in a latex agglutination-hemagglutinat...
Abortion in dairy cattle is generally defined as the loss of fetus on days 47-265 of pregnancy and can significantly reduce the income and capital gain of farmers and producers. Therefore, sufficient economical support and preventive measurements are essential for this issue. In this study, genetic materials were extracted from the abomasum rennet, as well as homogenous preparations of brain, k...
Measurement of von Willebrand factor antigen (VWF : Ag) levels is usually performed in a specialised laboratory which limits its application in routine clinical practice. So far, no commercial rapid test kit is available for VWF : Ag estimation. This paper discusses the technical aspect of latex agglutination method which was established to suit the purpose of estimating von Willebrand factor (...
Three commercially available rapid slide agglutination tests for the identification of Staphylococcus aureus were evaluated with 354 recent clinical isolates (165 strains of S. aureus). The test results of two latex agglutination products, SeroSTAT Staph (Scott Laboratories, Inc.) and Staphylatex (American Micro Scan), and one hemagglutination product, Staphyloslide (BBL Microbiology Systems), ...
Leptospirosis is an important global veterinary health problem caused by spirochetes belonging to the genus Leptospira. Leptospires are ubiquitous in nature, and therefore able to adapt to both the ambient environment and the renal tubules of chronically infected reservoir hosts. Microscopic agglutination test (MAT) remains a specialized test, which is not generally performed in the routine dia...
BACKGROUND An alternate HIV testing algorithm has been proposed which includes a fourth-generation immunoassay followed by an HIV-1/HIV-2 antibody differentiation supplemental test for reactive specimens and a nucleic acid test (NAT) for specimens with discordant results. OBJECTIVE To evaluate the performance of five rapid tests (Alere Clearview, Bio-Rad Multispot, OraSure OraQuick, MedMira R...
The potential contamination of Toxoplasma gondii and Neospora caninum oocysts in the human environment is a concern from the public health viewpoint. However, estimation of their seroprevalences in humans cannot be performed in a manner that distinguishes between oocysts and tissue cysts as a source of infection. Rabbits are considered popular pet animals in Japan that can acquire natural infec...
Toxoplasma gondii matrix antigen 1 (TgMAG1), known as the 65-kDa protein, which is abundantly expressed in both bradyzoites and tachyzoites, was evaluated as a candidate for the development of a diagnostic reagent for ovine toxoplasmosis. The TgMAG1 gene was expressed in Escherichia coli as a fusion protein with glutathione S-transferase (GST), and the recombinant TgMAG1 (rTgMAG1) was tested in...
This study aimed to determine the seroprevalence and to identify risk factors associated with Neospora spp. infection in horses in Jordan. Management related data were collected from each farm and individual horses. Sera from 227 horses from 5 of 6 climatic regions in Jordan were analyzed for the presence of antibodies to Neospora spp. by ELISA kit. The study was performed during spring of 2010...
two hundred and forty patients, who had undergone vasectomy from 1977 to 1985 and subsequent vasovasostomy ,were studied for the presence of sperm-specific antibodies by using the kibrick's gelatin agglutination test. the number of successful pregnancies and the presence of agglutination were also considered in this survey. sixty-nine pregnancies occurred in total and agglutination was present ...
