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...
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...
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...
Anthelminthic Agents01:15

Anthelminthic Agents

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
American Trypanosomiasis01:22

American 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...
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...

Area of Science:

  • Parasitology
  • Epidemiology
  • Infectious Diseases

Background:

  • Ascaris lumbricoides, a soil-transmitted helminth, infects 1.472 billion people globally.
  • Ascariasis is a neglected disease associated with substantial morbidity, especially in children.
  • Infection intensity is overdispersed, with a few hosts carrying most worms, and individuals show consistent re-infection patterns (predisposition).

Purpose of the Study:

  • To investigate the underlying mechanisms of Ascaris lumbricoides infection patterns and host predisposition.
  • To highlight the importance of understanding these phenomena for effective helminth control.

Main Methods:

  • The abstract does not detail specific methods but emphasizes the need for parallel observations in human subjects and animal models.
  • Epidemiological data from various geographical locations and age groups have identified consistent infection and re-infection patterns.

Main Results:

  • Consistent epidemiological patterns of Ascaris lumbricoides infection intensity and re-infection predisposition have been observed globally in both children and adults.
  • The mechanisms driving these observed patterns remain poorly understood and require further investigation.

Conclusions:

  • Understanding the mechanisms of susceptibility and resistance to ascariasis is essential.
  • Parallel studies in humans and animal models are vital for elucidating these mechanisms.
  • Insights into Ascaris intensity and re-infection patterns have implications for broader helminth control and co-infection management.
