In vivo Imaging of Transgenic Leishmania Parasites in a Live Host
Published on: July 28, 2010
Insights
Diagnosing visceral leishmaniasis can be challenging, often confused with lymphosarcoma. Electron microscopy successfully identified Leishmania parasites within splenic histiocytes in a difficult case.
Area of Science:
- Veterinary Medicine
- Parasitology
- Pathology
Background:
- Differentiating visceral leishmaniasis from lymphoplasmacell polimorphocell lymphosarcoma presents diagnostic challenges.
- Accurate diagnosis is crucial for appropriate treatment and patient management.
Observation:
- A case study involving a patient with suspected visceral leishmaniasis or lymphosarcoma was analyzed.
- The spleen was identified as a key organ for diagnostic investigation.
Findings:
- Electron microscopy provided definitive identification of Leishmania parasites.
- Parasites were detected within the histiocytes of the spleen.
Implications:
- Electron microscopy is a valuable tool for diagnosing challenging cases of visceral leishmaniasis.
- This technique aids in distinguishing parasitic infections from neoplastic conditions.
- Improved diagnostic accuracy can lead to better patient outcomes.
Abstract:
The differential diagnosis between visceral leishmaniasis and lymphoplasmacell polimorphocell lymphosarcoma may be difficult. One case is described in which electron microscopy allowed detection of Leishmania in the histiocytes of the spleen.

01:26Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:21Antiprotozoal Agents
Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
