Paper-disc method for Campylobacter hippurate-hydrolysis test. A note.

Paper discs were impregnated with sodium hippurate dissolved in 1/15 phosphate buffer pH 7.2. The discs, each containing 2 mg substrate, were stored in dry state at room temperature. After adding a disc to bacteria suspended in distilled water, and incubated at 37 degrees C for 2 h, one drop of Skirrow and Benjamin's ninhydrin reagent was added and the reaction was read after re-incubation at 37 degrees C for 10 min. 169 campylobacter strains were tested. The results for a total of 169 strains were identical with those obtained with the modified rapid method of Skirrow and Benjamin. Of 92 campylobacter strains isolated from human faecal samples 59.8%, of 36 strains isolated from slaughtered poultry 41.7% proved to be Campylobacter jejuni.

Immunoserology of Pseudomonas aeruginosa infections in man. III. Site of infection, duration of the presence of Pseudomonas aeruginosa and antibody response.

In 39 patients of a respiratory intensive care unit the intensity of the serological response to the purified LPS of the causative Pseudomonas aeruginosa was found to change according to the site of infection. The highest titres were found in septic cases, when the antigenic assault reached all the immune-competent cells in the body. Short presence (only one positive bacteriological culture) of P. aeruginosa at the site of inflammation resulted in a low or moderate rise in antibody titre. Ten days were enough for the development of a maximum total antibody (approximately IgM) response, while IgG type antibodies moderately grew further when the presence of P. aeruginosa lasted more than 10 days. Only a 16-fold increase in total antibodies per se or a 4-fold rise in both total (approximately IgM) and IgG antibodies confirmed the pseudomonas infection.
