149 ABSTRACT. Pseudomonas aeruginosa is generally considered to be an ubiquitous bacteria of water and soils, nevertheless in recent years particular attention has been paid to this microorganism because of its increasing significance as a human pathogen and its high resistance to most antibiotics. Nowadays, there are a variety of methods for the detection of P. aeruginosa using different cultu...

Pseudomonas Isolation Agar (selective agent, Irgasan, 25 mg/1) and Pseudomonas Selective Agar (selective agents, cetrimide 200mg/1 and nalidixic acid 15 mg/1) inhibited some strains of P aeruginosa from cystic fibrosis sputum but did not inhibit isolates from other sources. Of 200 cystic fibrosis isolates, 22 were inhibited by 16 mg/1 Irgasan, 45 by 8 mg/1 nalidixic acid, and 15 by 128 mg/1 cet...

Growth of Pseudomonas aeruginosa and thirty-five other species of gramnegative bacilli was observed on 0.03% cetrimide in heart infusion agar medium and Pseudosel agar (BBL). The 0.03% cetrimide agar was more selective for growth of P. aeruginosa than was Pseudosel agar; however, certain bacteria other than P. aeruginosa also grew on the former medium. Although Pseudosel agar was not a highly s...

The effects of acids and bases on the viscosity of salicylic acid-cetrimide systems were investigated. A viscosity reduction was produced by the addition of acids and was independent of the degree of saturation of the cetrimide solution with salicylic acid. The incorporation of base followed by that of acid increased and decreased the viscosity, respectively. This viscosity behavior was demonst...

The objective of the present study was to evaluate and compare the influence of cetrimide on decalcifying capability of different irrigating solutions. Fifteen maxillary central incisor teeth has been collected. The canals were prepared in order to obtain four samples from each root. The specimens were randomly divided into 6 experimental groups (n=10) according to tested irrigating agents. Irr...

The patient's sister had left hospital a few months earlier after sustaining a scald to the scalp which had required skin grafting. A proprietary shampoo had been recommended by a local shopkeeper to keep the scalp clean. One evening, another of the patient's siblings, her 7-year-old brother, rubbed some of this shampoo in during a nappy change. The patient was unsettled overnight, and presente...
