Comparison of four selective agars for the isolation of pseudomonads.
Significant differences were found between Dettol (chloroxylenol) agar, nalidixic acid-cetrimide agar, and two other cetrimide-containing agars used for the isolation of small numbers of pseudomonads.
متن کاملGrowth of coagulase-negative staphylococci on colistin-nalidixic acid agar and susceptibility to polymyxins.
Colistin-nalidixic acid agar, although recently recommended as a replacement for blood agar for primary plating of urine specimens ( Fung et al., J. Clin. Microbiol. 16:632-636, 1982), has also been reported to suppress the growth of some strains of staphylococci that are susceptible to colistin (polymyxin E). The susceptibility of 11 species of staphylococci to polymyxins was determined, and t...
متن کاملNalidixic acid: an antibacterial paradox.
Nalidixic acid was found to be most bactericidal against various species of gram-negative bacteria at 50 to 200 mug/ml. With all species tested, increases in the concentration of nalidixic acid above this range reduced, rather than increased, its bactericidal effect so that, at levels in the region of 400 mug/ml, the drug was relatively bacteriostatic. Therefore, the mode of action of nalidixic...
متن کاملInhibition of Pseudomonas aeruginosa from cystic fibrosis by selective media.
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...
متن کاملUse of an improved cetrimide agar medium and other culture methods for Pseudomonas aeruginosa.
In a comparison of two selective media for Ps. aeruginosa containing 0.03% cetrimide, stronger fluorescence was obtained from growth on the medium prepared with King's medium B as the base (CTA 2); although Ps. aeruginosa was not isolated more frequently from burns on this medium than from cetrimide agar made with a Lemco base (CTA 1), results were easier to assess and there were fewer cases of...
