[Frequency and relevance of some cross-, concomitant- and pseudo-cross allergies (author's transl)].

Examples of cross-, concomitant- and pseudo-cross allergies are discussed based on the results obtained in a series of patch tests made with 31 chemical allergens. Special attention is paid to the relevance of positivity. Para-group allergy is analysed as an example of cross-allergy. Analysis of various combinations of allergy to p-phenylene diamine and phenylisopropyl-p-phenylene diamine suggests that in addition to the classical cross-allergy, concomitant sensitization may also occur. Concomitant allergy to three metals (chromium, cobalt and nickel) is discussed. Concomitant sensitization to chromium and cobalt has been found to occur most frequently. Associated positivity to various aromatic balsam-like substances (balsam of Peru, turpentine, colophony, wood tar) has been interpreted as pseudo-cross-allergy.

Isolation and characterization of an R-prime plasmid from Rhizobium meliloti.

Using a simple enrichment procedure, we isolated an R-prime derivative of plasmid R68.45 carrying a 17.8-megadalton segment of the Rhizobium meliloti 41 chromosome. The chromosomal segment carried on this plasmid (pGY1) includes the markers cys-24+, cys-46+, and att16-3. Plasmid pGY1 mobilized the chromosome in a polarized way starting from the region of homology, but cannot promote chromosome transfer from other sites. The att16-3 site on pGY1 allowed the integration of phage 16-3 into pGY1, and a composite plasmid of 91.8 megadaltons was formed. This vector (pGY2) is suitable for the introduction of Rhizobium bacteriophage 16-3 into other gram-negative bacteria.
