Vibrio cholerae are Gram-negative bacteria that are differentiated into O1/O139 and non-O1/non-O139 serogroups depending on their ability to agglutinate with specific antiserum. In contrast to non-O1/non-0139 Vibrio cholerae, which are more prone to invade the bloodstream, Vibrio cholerae O1 is rarely the cause of bacteremia. We report a case of O1 Vibrio cholera bacteremia and primary peritoni...

The test is an application of the method originally described by Boyden (1951) and adapted by Stavitsky and Arquilla (1958). Sera which contain anti-Panton-Valentine leucocidin agglutinate the prepared red cells, often to a very high dilution, and this has provided a useful serological test for the diagnosis of staphylococcal disease in orthopaedic lesions. The test is quicker as a routine inve...

Lectin, a word of Latin origin, is a substance which is not triggered by antigenic stimulations in the immune system and which combines with an antigen in a way resembling that of an antibody. Accordingly, it can be described as a substance which can agglutinate cells or precipitate glycoconjugates, with a structure resembling a carbohydrate binding protein or glycoprotein and is not of immune ...

The life cycle of the trypanosomatid Crithidia fasciculata is monogenetic, as the unique hosts of these parasites are different species of culicids. The comparison of these non-pathogenic microorganisms evolutionary close to other species of trypanosomatids that develop digenetic life cycles and cause chronic severe sickness to millions of people worldwide is of outstanding interest. A ground-b...

By KI sI IO AH0 AND CHARLES L. CHRISTIAN I HE TREATMENT of red cells with some proteolytic enzymes has proved to be a suitable technic for the detection of a variety of blood group antibodies which coat but do not agglutinate erythrocytes in physiologic saline. The mechanism of this enzyme effect is not well understood. There is evidence that the antibodies revealed by the enzyme technic are no...

For the past few years, waste has become an increasingly popular topic among literary scholars. The sheer volume of areas knowledge involved in this highly interdisciplinary field been somehow blurred as labels “Waste Studies” and Theory” gained traction. Nevertheless, upon closer inspection those terms crumble easily. What is Theory”? attempts, if any, have made to agglutinate these disparage ...

A total of 393 clinical bacterial isolates were tested for their ability to agglutinate yeast cells of either Saccharomyces cerevisiae or Candida albicans. A positive agglutination of yeasts that could be prevented by methyl alpha-D-mannoside was taken as an indication for the possible presence of a mannose-specific lectin (carbohydrate-binding protein) on the surface of the tested bacteria. Ag...

1. "S" strains of Friedländer's bacillus produce capsules, soluble specific substance, and are of exalted virulence. "S" strains are type-specific and react with only the type-specific antibodies of the homologous types. 2. Immunization with "S" cells induces the formation of antibodies which agglutinate type specifically, precipitate the corresponding soluble specific substance, and protect wh...

Antisera raised against vegetative and gametic flagella of Chlamydomonas reinhardi have been used to probe dynamic properties of the flagellar membranes. The antisera, which agglutinate cells via their flagella, associate with antigens that are present on both vegetative and gametic membranes and on membranes of both mating types (mt+ and mt-). Gametic cells respond to antibody presentation ver...
