ABSTRACT

The authors report a case of a 36-year-old shizophrenic patient with left atrial thrombosis. There have been small number of case reports of antipsychotic drugs-associated thromboembolic events. All of them are venous ones. This paper describes the first case of atrial thrombosis associated with antipsychotic drugs.

ABSTRACT

To examine the optimal pH range for growth on media, growth of Legionella spp. on its selective media, BCYE alpha, WYO alpha and MWY agar media, in a pH range of 6.0-8.0 (at 0.5 intervals) was compared. The growth of two strains of L. pneumophila and one strain of L. micdadei on a WYO alpha agar supplemented with some selecting antimicrobial agents was markedly inhibited at all pH range except 6.0 and 7.0, suggesting a narrow optimal pH range for growth of these species compared to the BCYE alpha without selecting antimicrobioal agents. Vancomycin (VCM) added to the selective agar suppressed the growth of some Legionella spp. depending on the concentration. However, the extent of suppression was different among species and/or strains of Legionella spp. The selectivity for species other than Legionella spp. was also affected similarly by VCM concentration added to their media, suggesting that it is important to use proper amounts of the selecting antimicrobial agent depending on the species and/or strains of Legionella spp. or the other species in water samples. Amphothericin B (AMPH-B) added to a selective medium, MWY agar, in the concentration of 80 micrograms/ml hardly affected the growth of Legionella spp. examined, but effectively inhibited the growth of fungal strains identified as Aspergillus sp., Trichoderma sp., Scolecobasidium sp. and Mucor sp. which were isolated from cooling-tower water samples together with Legionella spp. Furthermore, the growth of a combination culture of one each of the 4 strains of isolated fungi and one each of the 3 strains of Legionella spp. was examined at various concentration of AMPH-B. Addition of AMPH-B to the selective medium at the concentration of 80 micrograms/ml suppressed the growth of spreading fungi, permitting the growth of Legionella spp. to allow efficient detection of the species.

ABSTRACT

Anti-microbial effect of the pretreatment with various organic acid buffer solutions against co-existing microorganisms which were isolated from cooling-tower water samples along with Legionella spp. was examined. Among several buffer solutions, a 0.1 M potassium citrate-citric acid buffer solution (hereafter, citrate buffer solution, pH 2.2) hardly affected the recovery of Legionella spp., but effectively inhibited the growth of co-existing microorganisms. To evaluate the buffer action of these buffer solutions, pHs of 9 cooling-tower water samples were evaluated after addition of an equal volume of each buffer solution. When a citrate buffer solution. pH 2.2 was combined to a 200-fold concentrated solution of each cooling-tower water sample, the pH of the combined solution became 2.5 to 2.7 and maintained a stably low pH value than that (pH 3.0 to 7.4) obtained after mixture of a 0.2 M HCl-KCl buffer solution (hereafter, HCl buffer solution, pH 2.2), suggesting strong buffer action of the citrate buffer solution, pH 2.2 in the combined solutions. Furthermore, when cooling-tower water samples were pretreated with a citrate buffer solution, pH 2.2, the recovery of Legionella spp. was successful in 7 out of 9 cooling-tower water samples, suggesting 3 times higher recovery rate than that obtained by addition of a HCl buffer solution, pH 2.2 (3 out of 9 cooling-tower water samples).
