Ring forms The earliest stage following red cell invasion has a typical ting form: a = chromatin dot b = digestive vacuole c = parasite cytoplasm Description At the earliest stage of red cell infection parasites of all species have the form of a "ring". Distinction between species at this stage may not be easy (or even possible). However as the parasites mature and develop, the differences between species become more apparent. In some species the ring appearance is maintained until late stages of maturation, in others it is lost as they mature. The different appearances of rings (or indeed the loss of ring forms) can be very useful in identifying the different malaria species. For details see individual species descriptions or galleries.
