Agglutination of motile salmonellas by acridines.
Genetic studies of the determination of Salmonella flagella have suggested that the alternative antigenic phases correspond to two distinct homology groups, i.e., to factors at two distinct genetic loci, one for phase 1 ("specific phase"), and one for phase 2 ("group phase") (Lederberg and Edwards, 1953). It has, however, been generally understood that the two phases were equivalent to one anot...

are not recovered from the blood, feces, or urine, is difficult by the agglutination test, where the patient's serum is treated with only one standard laboratory strain of B? typhosus ; the reason for this difficulty being that the serological differences between the standard laboratory strain and the irregular strain causing the infection may be so great that at the time when the diagnosis is ...
متن کاملSalmonella typhi and other salmonellas
There is almost a north-south divide between the geographical prevalence of the two broad clinical syndromes caused by the organisms of the genus salmonella. The prolonged bacteraemic illnesses of typhoid and paratyphoid fevers, caused by the exclusively human pathogens, Salmonella typhi and paratyphi A, B, and C, are endemic only in the economically disadvantaged countries where poor sanitatio...

متن کاملAgglutination by Precipitin
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...
