Synthesis, antimicrobial activity and toxicity to nematodes of cyclam derivatives.

The antimicrobial activity and toxicity to nematodes of the cyclam salt [H{H(PhCH)Cyclam}](CHCOO)⋅(CHCOOH) were evaluated. Estimated minimum inhibitory concentrations (MICs) of 9, 261 and 15 µg/mL were obtained for Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus, respectively. For selected Candida spp.

[Urinary tract infections and their prevention].

Context: This article reviews diverse aspects of the prevention of urinary tract infections, including confirmation of the diagnosis, application of hygiene and dietary measures, antibacterial prophylaxis (preferably consisting of a single nocturnal oral dose per day of an antibiotic or drug with high urinary excretion and good tolerance), and administration of vaccines made with Escherichia coli and other Gram-negative bacilli, consisting of immunostimulating fractions of E. coli strains or E. coli type-1 fimbriae administered through the parenteral or oral route.

[Early infection in liver transplant recipients: incidence, severity, risk factors and antibiotic sensitivity of bacterial isolates].

Objectives: To conduct a descriptive study with an analysis of risk factors for early infection in liver transplant patients, and to determine the resistance of the bacteria involved.

Patients And Methods: The study included 149 liver transplant recipients. All cases of infection occurring 0-90 days after transplantation were considered early infection.
