Potential Connection Between Diarrheal Disease and an Unconfirmed Ameboid-Like Structurem

A 70-year-old woman with no significant medical history presented to emergency room with abdominal pain and diarrhea. Routine stool tests for bacterial pathogens and fecal leukocytes were negative. However, microscopic examination revealed an unusual round structure with hyaline pseudopod-like extensions and a double membrane, devoid of visible internal structures or motility. Literature review suggested it might be Urbanorum sp, a controversial organism first described in the 1990s. While some studies propose Urbanorum sp. as a human pathogen, others suggest alternative explanations, such as plant-origin debris. The classification of this structure remains uncertain, highlighting the need for further research to determine its true nature and potential clinical significance.
