Naegleria fowleri is a free living amoebae that can be an opportunistic pathogen, and in some cases, has been diagnosed as the causative agent of the usually fatal amebic encephalitis. Other opportuni...

An ameba, Balamuthia mandrillaris, within a culture of monkey kidney feeder cells. Balamuthia extends from its branched pseudopodia while its rope-like body curves over and around a nucleus of a kidne...
