Chironomus plumosus midge larvae were collected from Lake Winnebago, Wisconsin, for 10 weeks in the summer of 1985 and 10 weeks in the summer of 1986 in order to determine their bacterial floras. Altogether, 18 genera and 29 species of bacteria were found and identified. Some spirillum-like bacteria which were not isolated in culture were found by electron microscopy. Scanning electron micrographs of sectioned larvae revealed bacteria throughout the intestines. Gram-positive organisms were most prevalent in the larvae in the early part of the summer, and gram-negative organisms were most prevalent during the later part. Larvae accumulate bacteria within their intestines.
1985 年夏天和 1986 年夏天，从威斯康星州的温尼贝戈湖采集了多毛摇蚊幼虫，以确定它们的细菌菌群。总共发现并鉴定了 18 属和 29 种细菌。通过电子显微镜发现了一些未在培养中分离的螺旋菌样细菌。幼虫切片的扫描电子显微镜照片显示细菌遍布肠道。革兰氏阳性菌在夏季早期的幼虫中最为普遍，革兰氏阴性菌在后期最为普遍。幼虫在其肠道内积累细菌。
