Go into the parasites pictures files and look at [greqfiles] click on the pics and you will see close-up of parasite in blood. The following two are pics of [1] stool sample, and [2] direct from culture plate after 4-5 days growth. This shows the same parasite which exists in blood and other body fluids {and possibly tissue} also emerges outside the body through scalp. The culture was taken of scalp debris, and grown for 4-5 days. As you can see, the potential for growth outside the body is huge. The culture plate was taken at very low magnification, whereas the blood was twice that. There is a total of 3 types. The first type is actual organism with "suckers" for attachment to organ tissue {not shown} the second type is seen in blood and stool samples and is more ribbon like, and the third type which is also in blood ect. exibits more of a fiber morphology and is reddish in color-not seen in photo.
