Comparative effectiveness of tetracycline, minocycline and doxycycline in treatment of acute-on-chronic bronchitis. A study based on sputum levels.
Ruhen RW, Tandon MK.
After the administration of minocycline, doxycyline and tetracycline in recommended therapeutic doses to 11, 10 and 12 patients respectively, sputum levels of these antibiotics were determined. Only 20% of patients given doxcycline had a satisfactory sputum level and in the remainder levels were either low or absent. For patients receiving tetracycline and minocycline, 67% and 64% respectively had satisfactory sputum levels. Patients selected for this study had a history of chronic bronchitis and were producing copious amounts of purulent sputum. Minimum inhibitory concentrations of these three antibiotics were similar for 25 freshly isolated strains of Haemophilus influenzae, with minocycline being the most inhibitory and doxcycline the least inhibitory.

In vitro susceptibility of Mycobacterium marinum to eight antimicrobial agents.
Sanders WJ, Wolinsky E.
The in vitro susceptibilities of 16 Mycobacterium marinum strains to eight antimicrobial agents were determined by the agar dilution technique. The most active drugs were amikacin and kanamycin. Tetracycline, doxycycline, and minocycline were inhibitory, predominantly at concentrations slightly below the expected blood and tissue levels. Trimethoprim-sulfamethoxazole and erythromycin demonstrated activity only at concentrations greater than those usually attained in serum and tissues. Gentamicin was relatively inactive.

A comparison was made for frequencies of isolation o glucose non-fermentative Gram-negative rods ((G)NF-GNR) from clinical specimens during a period from July, 1986 to June, 1987 (the first period) and that from January, 1994 to December, 1994 (the second period). Also, minimum inhibitory concentrations of principal drugs were determined against these isolates. The obtained results are summarized as follows: 1. Thirty four (34) species of (G)NF-GNR were found from 35,200 clinical specimens in the two periods. Numbers of strains of (G)NF-GNR obtained were 4,575 during the first period and 4,704 during the second period, thus no significant difference existed in numbers of strains isolated in the two periods. 2. Among the 34 species to which the 4,704 strains were classified into, Pseudomonas aeruginosa comprised 68.4%, Stenotrophomonas maltophilia 6.9%, Acinetobacter baumannii 5.6%, Burkholderia cepacia 3.1%, Acinetobacter Iwoffii 2.6%, Alcaligenes xylosoxidans subsp. xylosoxidans 2.4%, Flavobacterium indologenes 1.7%, Pseudomonas putida 1.1%, Acinetobacter junii 1.1% and Moraxella subgenus Moraxella lacunata 0.9%. When these frequencies of isolation were compared with those in the first period, it was found that B. cepacia decreased significantly (P < 0.01) and that S. maltophilia increased significantly (P < 0.001). 3. MIC determinations revealed multiple drug resistance strains in many different species of bacteria. Minocycline, however, were active against many such strains, and ofloxacin was found to have strong antibacterial activity against some strains.
