Insights

Cryptosporidium parvum is a gut pathogen causing diarrhea and inflammation. This review covers models for studying its pathogenesis and the immune system's role in fighting this parasite.

Area of Science:

  • Immunology
  • Parasitology
  • Gastroenterology

Background:

  • Cryptosporidium parvum is a protozoan parasite that infects intestinal epithelial cells.
  • Infection leads to diarrhea and significant mucosal inflammation.
  • Understanding host-parasite interactions is crucial for developing treatments.

Purpose of the Study:

  • To review in vitro and in vivo models for studying C. parvum pathogenesis.
  • To explore the roles of innate and acquired immunity in host defense against C. parvum.

Main Methods:

  • Literature review of existing models and immunological studies.
  • Analysis of host-pathogen interactions at the mucosal surface.

Main Results:

  • Various in vitro and in vivo models exist for C. parvum research.
  • Both innate and adaptive immune responses are critical for controlling infection.
  • Immune evasion strategies of C. parvum are key to its pathogenesis.

Conclusions:

  • Effective models are available for studying C. parvum pathogenesis.
  • Immune responses, both innate and acquired, are vital for host defense.
  • Further research into immune mechanisms can guide therapeutic strategies.

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...

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
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...
