    Insights

    Cryptosporidium infection was found in immunocompetent children with diarrhea. This parasite can cause acute gastroenteritis and chronic issues, including small bowel damage.

    Area of Science:

    • Medical Microbiology
    • Pediatric Gastroenterology
    • Infectious Diseases

    Background:

    • Cryptosporidium is a significant cause of diarrheal illness globally.
    • Its prevalence and clinical manifestations in immunocompetent children require further investigation.

    Purpose of the Study:

    • To determine the prevalence of Cryptosporidium oocysts in children with diarrhea.
    • To describe the clinical features and outcomes of cryptosporidiosis in immunocompetent children.

    Main Methods:

    • Modified Ziehl-Neelsen staining technique was used to identify Cryptosporidium oocysts in stool samples.
    • Stool samples were collected from children with acute or chronic diarrhea and healthy controls.

    Main Results:

    • Cryptosporidial oocysts were detected in 3.2% of children with diarrhea and 0.9% of controls.
    • All identified cases were immunocompetent, presenting with varied symptoms including acute watery diarrhea and chronic diarrhea with failure to thrive.
    • Small intestinal enteropathy and colitis were observed in some cases, with parasite presence confirmed in stool and jejunal mucosa.

    Conclusions:

    • Cryptosporidial infestation is associated with acute gastroenteritis in immunocompetent children.
    • It can also lead to chronic diarrhea and small bowel damage in this population.
    • Travel history and family outbreaks suggest potential transmission routes.

    Immunodeficiency Diseases

    Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
    There are three main causes of immunodeficiency disorders...
    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...
    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,...
    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...
    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...
