The increase of fungal infections in recent years is connected with the progress in medicine. The vast usage of biomaterials is an inseparable element of contemporary medicine but it also leads to development of infections. Yeast-like fungi Candida albicans are still the main pathogen of candidiasis. The ability to slime production and adhesion to polystyrene of Candida sp. on different surfaces can cause to form biofilm on surfaces of biomaterials used in production of catheters, drains and prosthesis. The aim of the study was to evaluate the influence of slime production and adhesion to polystyrene, of Candida sp. on biofilm formation on different biomaterials. 50 strains of Candida sp. were examined. They isolated from ill to Clinics of Anesthesiology and Intensive Therapy University Hospital No 1 of dr. A. Jurasza in Bydgoszcz. The ability to slime production was evaluated by Christensen method in modification Davenport and Branchini methods. The adhesion to polystyrene was evaluated by Richards et el method. The ability to produce biofilm biomaterials by the studied fungi was measured after 72 hours of incubation at 37 degrees C on different biomaterials. Yeast-like fungi Candida sp. fabricating slime and adhesion forming frequently biofilm on surface researched of biomaterials. Influence of chosen biological specificity ascertain on the ability to produce biofilm on surfaces of siliconized latex and polyvinylchloride.
近年来真菌感染的增加与医学进步有关。生物材料的广泛使用是当代医学不可或缺的要素,但它也会导致感染的发生。酵母样真菌白色念珠菌仍然是念珠菌病的主要病原体。念珠菌属在不同表面产生黏液和黏附于聚苯乙烯的能力,可导致在用于生产导管、引流管和假体的生物材料表面形成生物膜。本研究的目的是评估念珠菌属产生黏液和黏附于聚苯乙烯的能力对不同生物材料上生物膜形成的影响。检测了50株念珠菌属菌株。它们是从比得哥什市A. 尤拉萨博士第一大学医院麻醉学与重症治疗诊所的患者中分离出来的。采用经达文波特和布兰奇尼方法改良的克里斯滕森方法评估产生黏液的能力。采用理查兹等人的方法评估对聚苯乙烯的黏附力。在37℃下于不同生物材料上孵育72小时后,测定所研究真菌在生物材料上产生生物膜的能力。酵母样真菌念珠菌属产生黏液并黏附,常在生物材料的研究表面形成生物膜。所选择的生物学特性对在硅化乳胶和聚氯乙烯表面产生生物膜能力的影响。
