Structural localization and kinetics of incorporation.","authors":"M Cortat","doi":"","DOIUrl":"","url":null,"abstract":"Phenylmercuric borate (PHB) is very rapidly incorporated into the cells of Escherichia coli, and binds directly to its sites of fixation. The rapid incorporation of PHB probably results from the lipophilic character of the [phenylmercuric]+ cation. The distribution of PHB in the cell is fairly uniform if one compares with that of the proteins. This shows the low specificity of PHB with regard to proteins, all of which appear to be potential sites for fixation. However, from the structural point of view, PHB is more differentiated in its distribution. The cell wall of E. coli and the soluble cytoplasmic fraction do not constitute important sites of fixation. On the contrary, the cytoplasmic membrane appears to be a preferential site of fixation. Moreover, it is very probable that the distribution of PHB in vivo should be even more likely at the cytoplasmic membrane since the process of homogenization of the cells solubilizes a large part of the proteins associated to the membrane. On the membrane, an important part of PHB seems to be associated with the ribosomes and particularly to the ribosomal proteins.","PeriodicalId":76868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

Biochemical localization and inhibition of some metabolic activities.","authors":"M Cortat","doi":"","DOIUrl":"","url":null,"abstract":"The biochemical localization of phenylmercuric borate (PHB) on Escherichia coli shows that this disinfectant associates essentially with proteins. Protein electrophoresis demonstrates that each protein contains PHB, and that SH groups play a very important role in its fixation. The quantity of PHB able to associate with proteins is so large that many other electron donor groups must react with it. Moreover, it appears that concentration of PHB on cytoplasmic membrane results rather from the privileged position of this structure than from special physicochemical properties. The great reactivity of PHB towards proteins leads to numerous inhibitions and confers upon this antibacterial drug a very complex mode of action. Four important metabolic activities have been tested in the presence of PHB, namely: respiration, protein-synthesis, RNA synthesis and DNA synthesis. These four metabolic functions are rapidly and totally inhibited at low concentrations of PHB. The complexity of the mode of action of PHB makes the adaptation of bacteria to this disinfectant more difficult. In addition, in the case of plasmid dependent resistence, PHB, with its complexe mode of action, does not favour such a selection in opposition to the antibiotics which generally have a more specific mode of action.","PeriodicalId":76868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

Imported diseases from the tropics (exotic diseases) 2. Imported agents from the tropics with human infection in the native country 3. Re-importation of diseases which were eliminated in the homelands 4. Diseases which are as well imported as also native 5. Single disease importations from neighboured countries. The imported infections are discussed systematically, caused by viruses, rickettsias, bacteries, protozoes, fungi, and followed by references to statistics, laboratory infection reports, questions of insurance. Imported diseases of the future are especially mentioned. Knowledge of the tropical infections as a main danger for our \"civilized\" world should be part of the medical training, since imported infectious diseases cause an epidemiologic challenge in the modern picture of communicable infections.","PeriodicalId":76868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

The count of M. intracellulare serotyp Davis decreases rapidly already in three days after the inoculation of Sph. magellanicum Ass. and this trend in the course of incubation is being continued. In 27 days following the inoculation only 2 of 7 specimens contained a small amount of this mycobacteria (Tab. 2, Fig. 2). In the head region of Sph. apiculatum Ass. the mycobacterial count was more rapidly going down. Already 13 days after the inoculation only 2 of 7 specimens were found mycobacteria-positive; 24 days after the inoculation no mycobacteria were present (Tab. 3, Fig. 3). The elimination of M. avium from the head region of Sph. magellanicum Ass. follows within 13 days after the inoculation (Tab. 4, Fig. 4). For the microbial growth well predisponated hyaline cells with their porous cell wall and hollow spaces possess probably a mechanism, which is effective against microbial contamination of the productive head region of Sphagnum vegetation. Our further investigations have shown, that the growth of mycobacteria follows in the deeper, partially decomposed region of Sphagnum vegetation (KAZDA, 1978).","PeriodicalId":76868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.
