Bacteriological examination of the early morning sputum from 54 patients with chronic bronchitis, half of whom received chemoprophylaxis with oxytetracycline, was made regularly for periods up to four and a half years. Nasal and perineal swabs were taken for periods up to three and a half years. There was no evidence that frequent or dangerous proliferation of drug-resistant organisms occurred ...

Rabbits were infected with a bovine strain of Besnoitia besnoiti parasites derived from VERO cell cultures. Oxytetracycline, given at 30 mg/kg i.m. simultaneously with infection, prevented the development of orchitis. The controls received no treatment. All infected animals showed a transient febrile reaction. It is concluded that oxytetracycline has some therapeutic potential against Besnoitia...

Material and methods The study was conducted in the Venereal Diseases Department, St. Bartholomew's Hospital, London. The diagnosis of nongonococcal urethritis was based on the presence of a sexually acquired urethral discharge, containing abundant polymorphonuclear leucocytes, shown not to be due to gonorrhoea by negative findings in Gramstained smears and by negative results to cultures. Case...

Combining the high specificity of bacterial biosensors and the resolution power of fluorescence-activated cell sorting (FACS) provided qualitative detection of oxytetracycline production by Streptomyces rimosus in soil microcosms. A plasmid containing a transcriptional fusion between the tetR-regulated P(tet) promoter from Tn10 and a FACS-optimized gfp gene was constructed. When harbored by Esc...

Six strains of enteropathogenic gram-negative bacteria were tested for susceptibility to neomycin or oxytetracycline alone and combined in fixed ratios. The minimal inhibitory concentration for the combination was less than one-half of that expected if the antibiotic activities were simply additive. Neomycin alone was more effective against bacteria multiplying in the presence of abundant oxyge...

A prospective, randomised, double blind, partial crossover, placebo controlled trial has been conducted to compare the performance of topical fusidic acid gel (Fucithalmic) and oral oxytetracycline as treatment for symptomatic chronic blepharitis. Treatment success was judged both by a reduction in symptoms and clinical examination before and after therapy. Seventy five per cent of patients wit...
