Penicillin is widely known as the best and most suitable remedy in the treatment of gonorrhoea, but gonococcal sensitivity to penicillin decreased in Norway as well as in other countries (Gjessing, 1959; Gjessing and Odegaard, 1964; Galstrin and Kallings, 1964; Reyn, Bentzon, Thayer, and Wilkinson, 1965). Sensitivity to penicillin has been found to vary considerably in gonococci isolated from d...

We have detected trace amounts of molecules of antibiotics (kanamycin sulfate) dispersed on metasurfaces with terahertz (THz) spectroscopy. Utilizing the extraordinary optical transmission resonance of an array of square-shaped slits on a silicon substrate at ~0.3 THz, we were able to monitor varying concentrations of kanamycin sulfate as low as ~100 picogram/L. In contrast, the lowest detectab...

BACKGROUND Potassium ion homeostasis plays an important role in regulating membrane potential and therefore resistance to cations, antibiotics and chemotherapeutic agents in Schizosaccharomyces pombe and other yeasts. However, the precise relationship between drug resistance in S. pombe and external potassium concentrations (particularly in its natural habitats) remains unclear. S. pombe can to...

This study was performed to detect cultivable canine gastric Helicobacter-like organisms (GHLO’s) and to evaluate their sensitivity to common antibiotics in two groups of naturally infected dogs (pets and stray dogs). Gastric samples were taken from the body and antrum of 30 pets and 30 stray dogs. From each part of canine gastric mucosa, four gastroscopic samples were used for impression smear...

The effects of ten antibiotics and two preservatives on the rabbit corneal endothelium were studied by in vitro perfusion. Dose-related effects on corneal thickness were seen with certain antibiotics. No correlation was found between structure, origin, or bacterial sensitivity of the antibiotics and their effect on corneal transplants. Five distinct morphological changes were observed: two were...
