1. Antibodies to slime molds were produced by injecting D. discoideum and D. purpureum amebas from 48 hour cultures into rabbits. 2. Anti-D. discoideum and anti-D. purpureum sera caused agglutination of homologous amebas from 24 to 26 hour cultures, agglutination of certain heterologous amebas from 30 to 36 hour cultures, and agglutination of all heterologous amebas from 43 to 48 hour cultures....

A new slide latex agglutination test was compared with microscopy and culture for diagnosing vaginal candidosis in 367 women attending a genitourinary medicine clinic. Vaginal candidosis occurred in 10% of the patients, and 7% had commensal carriage of Candida spp. The slide latex agglutination test was superior to microscopy in immediate diagnosis and was rapid and simple to perform. Of the pa...

The author and his co-workers have found out that, when the diluents including egg yolk for freezing of boar spermatozoa were used, egg yolk agglutinated immediately after the dilution and most of the spermatozoa were enclosed into the agglutinated masses and their motility was drastically suppressed. On the other hand, by using skim milk-diluent widely used for storing liquid boar semen at 15°...

A microtechnique has been developed and adapted successfully to the microscopic agglutination test with live antigens for detection of leptospiral antibodies. Simultaneous titrations were performed by the conventional microscopic agglutination test and the microtechnique. When the microtechnique was used to screen 50 unknown leptospiral strains with a battery of hyperimmune sera, 98% agreement ...

Serum (antigen) when heated at a temperature sufficient to cause definite clouding reacts more intensely with a specific precipitin than a portion of the unheated serum or samples heated at lower temperatures. The phenomenon is explained on the basis that coagulated protein in suspension is covered with undenatured antigen and the addition of precipitin causes agglutination of the coagulated pr...

In two recent articles in the Journal of Clinical Microbiology, Qian et al. (4) and Lagace-Wiens et al. (2) describe a direct coagulase and a thermostable DNase test, respectively, for direct identification of Staphylococcus aureus from positive blood culture bottles. In a prospective study from April 2003 until February 2004, we investigated the accuracy of the Slidex Staph Plus agglutination ...
