Summary
Toxocara infection in children may be linked to asthma and bronchitis. This study found a higher prevalence of these respiratory conditions in children with Toxocara antibodies, suggesting a potential causal relationship.
Area of Science:
- Epidemiology
- Immunology
- Pediatrics
Context:
- Investigated 234 children aged 3-6 years in The Hague, Netherlands.
- Assessed seropositivity for Toxocara antibodies.
- Excluded cross-reactions with Ascaris antibodies.
Purpose:
- To determine the prevalence of Toxocara antibodies in young children.
- To explore the potential association between Toxocara infection and respiratory conditions like asthma and bronchitis.
Summary:
- 11.1% of children (26 out of 234) were seropositive for Toxocara.
- Seropositive children showed a significantly higher incidence of asthma or bronchitis (31%) compared to seronegative children (12%).
Impact:
- Findings suggest a potential link between toxocariasis and childhood asthma/bronchitis.
- Further research could confirm toxocariasis as a preventable cause of these respiratory illnesses.

Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
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...
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...
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...
