Cloning and characterization of a Neisseria gene homologous to hisJ and argT of Escherichia coli and Salmonella typhimurium.

We have isolated from a genomic library of the pathogenic Neisseriae gonorrhoeae T2 strain, a gene encoding a putative protein of 268 amino acids which exhibited significant similarity to the hisJ and argT gene products of Salmonella typhimurium and Escherichia coli, periplasmic proteins deputed to amino acid transport within the cell. The gene is transcribed as a monocistronic mRNA species of about 960 nucleotides flanked by regulatory elements for initiation and termination of transcription that are efficiently recognized in an E. coli host.

[Normal anatomy of the patella in advanced age].

The form of the kneecap is determined by heredity. It is modified by the various tissue-modeling, functional-mechanical forces acting on it in the course of life. The individual "face" of a patella is the result of these two factors, including any malformations or pathologic changes of the tissue (in particular the cartilage). Numerous measurements were made on patellae of elderly subjects - obtained from autopsies and without any apparent macroscopic changes apart from those which were age-related, such as cartilage color - in order to map the ideal patellar shape, which would appear to be unsusceptible (or less susceptible) to pathologic disturbances.

[Comparative study of the drug resistance of strains of enterobacteria isolated from hospitalized and ambulatory patients].

The Kirby-Bauer technique was employed in an assessment of the in vitro resistance to 8 antibiotics of 166 Enterobacteriaceae strains, isolated during routine diagnostic operations from various biological materials derived from wards, and from hospital out-patients. Their chemoresistance characteristics were also examined. It was found that Proteus strains from in-patients were more resistant to some antibiotics than those from out-patients. E. coli strains from in-patients were more frequently resistant to gentamycin.
