Insights

Cryptosporidium sp. intestinal infections were found in 10% of patients with lymphoproliferative diseases. This parasitic infection was not detected in the healthy control group, suggesting a potential link in immunocompromised individuals.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Hematology

Background:

  • Cryptosporidium sp. is an opportunistic protozoan parasite.
  • Patients with lymphoproliferative diseases often have compromised immune systems.
  • Intestinal infections can be a significant concern in immunocompromised populations.

Purpose of the Study:

  • To determine the frequency of intestinal Cryptosporidium sp. infection in patients with lymphoproliferative diseases.
  • To compare infection rates between patients and a healthy control group.
  • To investigate the association between Cryptosporidium sp. and lymphoproliferative disorders.

Main Methods:

  • Stool parasitological tests were employed to detect Cryptosporidium sp. oocysts.
  • A study group of 60 patients with lymphoproliferative diseases was examined.
  • A control group of 59 healthy individuals from the same geographical area and with similar life-time exposure was included.

Main Results:

  • Cryptosporidium sp. oocysts were identified in 6 out of 60 patients (10%) in the lymphoproliferative disease group.
  • No Cryptosporidium sp. infections were detected in the 59 individuals of the control group.
  • Only one infected patient presented with diarrheal symptoms.

Conclusions:

  • Patients with lymphoproliferative diseases exhibit a higher prevalence of Cryptosporidium sp. intestinal infections compared to healthy individuals.
  • The findings suggest that immunocompromised status associated with lymphoproliferative diseases may increase susceptibility to Cryptosporidium sp.
  • Further research is warranted to understand the clinical implications and management of Cryptosporidium sp. in this patient population.

Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
