title: [Morphology of fungi in the slides prepared from esophageal balloons].
abstract: 1,762 cases were selected at random from 17,000 persons screened by esophageal balloon in 4 communes of Linxian County. The morphologic appearance of fungi was studied in 4 slides of each case selected. According to the shape of clumps formed by fungi and bacteria in the slides, morphologic 4 types were seen: cotton-like, camel hair-like, hair-like and tree-branch-like. In the preliminary microscopic analysis, the following species of fungi were noted: Candida, Leptothrix, Actinomyces, Alternaria, Fusarium and Penicillium. Some of the fungi in the slides may have been taken from the oral or pharyngeal cavity, which may be due to, at least in part, the poor oral hygiene in the population examined. A positive association was shown between the quantity of fungi in the slides and the esophageal epithelial dysplasia and carcinoma, but its biological significance should be studied further.
