The paper-strip blood-sampling technique was evaluated for efficacy in plague passive hemagglutination tests. It is valuable for widespread serological surveys.

Reactions of selected antiglobulin sera with sensitized cells are related to their precipitation patterns with normal serum on immunoelectrophoresis. The components which react with adsorbed complement are anti-beta(1) and further evidence of this is obtained by the effect of the addition of human serum components on the antiglobulin reactions with ;complement-coated' cells. The findings are di...

Background: Diagnostic and therapeutic approaches in syphilis show wide variation. The use of only one type of serological test is insufficient for diagnosis. Objective: The aim of the study was to review serologic data to determine diagnostic performance of three different methods of syphilis patients from MGM Hospital, Warangal in urban and rural areas during period of 2012-2013. Materials & ...

The fluorescent treponemal antibody (FTA) test developed by Deacon, Falcone, and Harris (1957) and later modified with the absorption procedure by Hunter, Deacon, and Meyer (1964) has contributed much to the better diagnosis and control of syphilis in many parts of the world (WHO Scientific Group Report, 1970). The test combines the sensitivity and specificity of immunofluorescence with easy re...

Candidiasis is defined as an infection or disease caused by a fungus of the genus Candida. Rate of disseminated candidiasis increases with the growth of the number of immunocompromised patients. In the the last few decades the incidence of disseminated candidiasis is in growth as well as the mortality rate. The aim of this survey is to show the importance of serological tests implementation in ...

The aim of the present study was to compare serological tests (Rose Bengal [RB]; standard agglutination test [SAT]; enzyme immunoassay [EIA] for detection of IgM, IgA, and IgG; and 2-mercaptoethanol [2-ME] test) that are routinely used in patients prediagnosed with different clinical types of brucellosis (acute, subacute, or chronic), and to evaluate the results of the IgG avidity test. Ninety-...

Acute and chronic biological false positive reactions to serological tests for syphilis are discussed. Three cases are presented, one showing an acute and one a chronic reaction, and one in which it was not possible to determine if the reaction was acute or chronic. Once a biological false positive reaction is found, serum from the patient should be tested at intervals for at least six months t...

The standard complement fixation (CF) test, a commercial agarose gel immunodiffusion (AGID) test (ImmuCell Corporation, Portland, Maine), and two commercial enzyme-linked immunosorbent assays (ELISAs; Allied Laboratories, Glenwood Springs, Colo. [Allied ELISA], and the CSL, Limited, [Parkville, Victoria, Australia] enzyme immunoassay [CSL ELISA]) were evaluated by using sera from the Repository...
