In our case, the proposed entry route of infection is ascending retrograde from the biliary tract. Bile and aspirated pus culture repeatedly tested positive, and blood negative, for Candida albicans and Candida glabrata. Cholecystitis was cured by percutaneous gallbladder drainage and amphotericin B therapy. The liver abscesses were successfully treated by a cumulative dosage of 750 mg amphotericin B. We conclude that in cases involving less immunocompromised patients and those without candidemia, a lower dosage of amphotericin B may be adequate in treating candidal liver abscesses.展开更多

This is the first report that a case of liver abscess due to Candida albicans was completely cured with intra-abscess and intravenous administration of liposomal amphotericin B without recurrence in three-year follow-up period.展开更多

Con A （Concanavalin A）, WGA （wheat germ agglutinin）, UEA-I （Ulex europeus agglutinin I） and PNA （peanut agglutinin）, all conjugated with horseradish peroxidase, were used. For the susceptibility tests, sterilized fiat-bottomed 96-well microtitre plates were used and the procedures were followed of the Clinical and Laboratory Standard Institute. The inoculum was added to the wells with the tested drugs and the plates were incubated at 25 ℃ for 48 h before reading the results to determine the MIC （minimal inhibitory concentration） of AMB, VOR and ITC. All Aspergillus strains showed low MIC for AMB （0.031-1 μg/mL） and ITC （0.031-0.25μg/mL）. However, the isolates were less susceptible to VOR, for which the MIC ranged from 4 to 16 μg/mL. The results of this study indicate that the expression of N-acetyl-D-glucosamine and glucose/mannose on the cell wall surface of the Aspergillus species evaluated showed greater stability of expression in the fungal growth both in vitro and in parasitism.展开更多
目的：通过扫描电镜和透射电镜观察马尔尼菲青霉菌临床株经两性霉素 B 和伏立康唑作用前后超微形态的变化。方法采用微量稀释法先测定两性霉素 B 和伏立康唑对马尼菲青霉菌临床株的最小抑菌浓度（MIC），在 MIC 和10倍 MIC 条件下，药...目的：通过扫描电镜和透射电镜观察马尔尼菲青霉菌临床株经两性霉素 B 和伏立康唑作用前后超微形态的变化。方法采用微量稀释法先测定两性霉素 B 和伏立康唑对马尼菲青霉菌临床株的最小抑菌浓度（MIC），在 MIC 和10倍 MIC 条件下，药物与菌作用24、48、72 h，分别在扫描电镜和透射电镜下观察马尔尼菲青霉菌的超微结构变化。结果马尔尼菲青霉菌经两性霉素 B 作用后，随着药物作用时间延长及浓度增加，扫描电镜下可见到菌体破损，外层剥离、皱缩、断裂及粘连；透射电镜下线粒体变性，细胞核碎裂，细胞膜皱缩，胞质内细胞器消失，细胞壁断裂。经伏立康唑作用后，扫描电镜下可见到菌体破损、皱缩、干瘪、坍塌；透射电镜下均看到胞质内出现许多高密度的电子致密颗粒，线粒体变性，细胞壁表面粗糙，细胞膜皱缩、破损，胞质内各细胞器消失。结论两性霉素 B 和伏立康唑对马尔尼菲青霉菌有明显抗菌作用，均可使其超微结构发生明显变化，与药物浓度及作用时间呈正相关。两种药物相比，两性霉素 B 对菌细胞损伤更明显。展开更多

Results The clinical manifestations of the 18 cases were: insidious onset, fever, severe headache, generalized pain, nausea and vomiting, weight loss and dehydration, and enlarged cervical lymph nodes. Boa's and Cullen's signs were positive. The positive rates of cerebrospinal fluid (CSF) India ink stain and the polysaccharide capsule antigen (ELISA) were 77.8% and 99.4%, respectively. The positive rate of CSF culture of cryptococcus was 100%. The mortality rate was 83.3%.Conclusion Cryptococcal meningitis is the most common opportunistic infection and one of the major causes of deaths in AIDS patients. The misdiagnosis and mortality rates were very high and could be explained by a lack of awareness for the occurrence of AIDS with cryptococcal meningitis, late presentation, serious illness and severe complications, and delayed and inadequate therapy.展开更多
