LATEX/IgM, a rapid agglutination test for the semi-quantitative detection of IgM in cerebrospinal fluid of patients with African trypanosomiasis, is described in this article. The lyophilized reagent has been designed for field use and remains stable at 45 degrees C for one year. The test has been evaluated on cerebrospinal fluid samples from trypanosome-infected and non-infected patients, by c...
background: new cases of visceral leishmaniasis (vl) have been reported recently in some parts of mazandaran province, north of iran where the first human case of vl was reported in 1949. this study aimed to determine the present status of leishmania infantum infection among humans and domestic dogs using serological and molecular methods in central parts of mazandaran province. methods: in th...
Recombinant Neospora caninum tachyzoite antigens were evaluated in an enzyme-linked immunosorbent assay (ELISA) for recognition by serum antibodies (Ab) from Neospora-infected cattle. Serum samples were obtained every 2 to 3 weeks for 8 to 15 months from 10 cows with histories of Neospora-associated abortion. Serum samples were also obtained from offspring of these animals and from a large numb...
1. The agglutination titer for chicken red cells of freshly prepared or carefully stored suspensions of PR8 influenza virus, that is to say virus of maximum pathogenicity, was found to be proportional to the mouse lethal titer of the same preparations. 2. The agglutination titer of infected allantoic fluid procured in a standard way is relatively constant, regardless of the influenza strain use...
A simple, rapid mixed agglutination test using sheep erythrocytes (SRBC) sensitized with rabbit hemolysin and intact viable staphylococci is described for the detection of bound staphylococcal protein A. Soluble protein A was heat extracted from 50 clinical isolates as well as the Cowan I and Wood 46 strains of Staphylococcus aureus and titered by a hemagglutination test using sensitized SRBC a...
We evaluated the reliability of a passive bacterial agglutination test to detect Salmonella typhi somatic antigen(s) in the sera of patients with typhoid fever. It was positive in 32 of 33 bacteriologically proven typhoid fever cases. Among 13 patients with a presumptive diagnosis of typhoid fever, 11 were positive by passive bacterial agglutination. The serum of one patient with paratyphoid A ...
We report a case of a patient who experienced a catheter-related bloodstream infection caused by Staphylococcus condimenti, which was first isolated from soy sauce mash. This is the first reported case of human infection. Although blood culture isolates and the catheter tip tube did not reveal coagulase or clumping factor, false-positive results were obtained from latex agglutination tests for ...
A latex agglutination test was evaluated as a method for detection and titration of antiplague antibodies. Slide and microtiter techniques using polystyrene latex particles coated with specific fraction-I-antigen of Yersinia pestis were found to be comparable in specificity and sensitivity to serological tests commonly used in laboratory practice. The latex agglutination titers correlated well ...
BACKGROUND/AIM In the 2012/13 winter semester, the Magdeburg Medical Faculty introduced a test of knowledge for the selection of applicants. The Hamburg Assessment Test for Medicine - Natural Sciences (HAM-Nat) comprises a multiple-choice test with questions on the aspects of biology, physics, chemistry and mathematics relevant to medicine, which was specifically developed for the selection of ...
A method has been described for the preparation of Treponema pallidum suspensions that are suitable for specific agglutination studies and can be stored at 4 degrees C. for months without loss of agglutinability. Such suspensions have been shown to react with two distinct antibodies in the serum of syphilitic animals and man: Wassermann antibody and a specific treponeme agglutinin. It has been ...
