وصف قصير

⧼wm-license-information-description⧽Schistosomal cercaria.jpg	English: This historic 1942 photomicrograph revealed some of the morphologic details displayed by a schistosomal cercaria, which is the larval stage of a parasite that causes “swimmer’s itch”, and was magnified approximately 150x. This was one of a series of instructional images used by the Minnesota Board of Health to train its state public health workers. The purpose of the images and the accompanying training was focused on protecting potable water supplies from contaminants including toxins, and pathogenic organisms, such as the parasite pictured here. This material was obtained from Professor William A. Riley, of the University of Minnesota. The sample itself was taken from Lake Owasso, Minnesota.
