Important aspects for the today therapy and prophylaxis with antibiotics/chemotherapeutics resp. are represented (choice of the antibiotic, treatment with antibiotic or sulphonamide, bacteriostatic or bactericidal activity, combination possibilities with examples). A strong indication for the application of chemotherapeutic agents is demanded. The necessity(More)
Resistance to complement-mediated serum activity is an important virulence factor in E. coli isolated from extraintestinal infections. Because there are no reports about the percentage of serum-resistant E. coli strains in common O serogroups, the study was carried out using Taylor's method (75% serum) for the determination of serum resistance of 253 E.(More)
Bacterial infectious complications are the most common cause of morbidity and mortality associated with acute pancreatitis. Most pathogens are common gastrointestinal flora, indicating that the gut is the source of pancreatitis-related infections. However, the route whereby the microorganisms reach distant organs remains speculative. We tested the(More)
A total of 36 Escherichia coli urinary tract isolates (UTI) of serotype O6, with different combinations of capsule (K) and flagellin (H) antigens, were analysed according to the outer membrane pattern (OMP), serum resistance properties, mannose-resistant hemagglutination using various types of erythrocytes, and also for the genetic presence and the(More)
Escherichia coli isolates of serotype O6:K5 are the most common causative agents of cystitis and pyelonephritis in adults. To answer the question, as to whether strains of this particular serotype represent one special clonal group, out of a collection of 34 serotype O6:K5 isolates [Zingler et al. (1990) Zentralbl. Bakteriol Mikrobiol Hyg [A] 274:372–381](More)
Serotyping of 1918 Escherichia coli strains isolated in significant cell numbers from the urine of patients with urinary tract infections (UTI) revealed the presence of 117 O6 strains. The K antigens were identified by means of K-specific phages and serological methods. The phages used included a K1 phage pool (phi 1, A-E) and the separate phages phi 2, phi(More)
1. Patients receiving regular hemodialysis treatment who are permitted to select their own diets are in danger of a protein deficiency manifested by a significant reduction in serum transferrin and in complement C3c. 2. Correlation analysis within the dialysis group revealed no secure connexion between the complement C3c and total hemolytic activity(More)
BACKGROUND A major goal in research on intraocular lenses (IOL) is the development of new polymers and modifications to reduce foreign-body reactions after implantation. This effect may be achieved by a reduction in the surface hydrophobicity of the polymers. To illustrate the influence of surface modifications on bacterial adhesiveness, the most often(More)
