Agglutination of Bordetella species by lectins

Lectins agglutination test as an epidemiological marker for Neisseria gonorrhoeae.

Agglutination of Sindbis virus and of cells infected with Sindbis virus by plant lectins.

We have examined the agglutination of Sindbis virus and of chick and hamster cells infected with Sindbis virus by two of the plant lectins, concanavalin A and Ricinus communis agglutinin. Both lectins agglutinate the virus by binding to the polysaccharide chains of the envelope glycoproteins. Both chick and hamster cells exhibit increased agglutination by the lectins after infection by Sindbis ...

Cell hybridization and cell agglutination. I. Enhancement of cell hybridization by lectins.

A great increase in hybridization frequency of cultured rodent cells was obtained when conventional cell fusion using 50% polyethylene glycol (PEG) was combined with a cell agglutination produced by plant lectins. The rate of appearance of hybrid colonies was found to be correlated with the extent of cell agglutination by lectin, as well as with cell fusion induced by subsequent PEG treatment. ...

Bacteremia caused by a novel Bordetella species, "B. hinzii".

Bordetella spp. cause respiratory tract diseases in warm-blooded animals. Only Bordetella bronchiseptica has been reported to cause bacteremia in humans, and this rare infection usually occurs with pneumonia in immunocompromised patients. We describe "Bordetella hinzii" bacteremia in an AIDS patient without a respiratory illness. Combining biochemical phenotyping with fatty acid analysis permit...

EVALUATION OF SERUM OPSONIC CAPACITY AGAINST BORDETELLA PERTUSSIS BY CHEMILUMINESCENCE

Serum opsonic capacity against B. pertussis was studied by using quantitative chemiluminescence (CL), a method known to have several advantages over conventional methods in evaluating opsonization and phagocytosis. Sera from unvaccinated infants was shown not to contain opsonins against B. pertussis and in unvaccinated infants suffering from whooping cough, no opsonins were detected. In ad...
