Abstract

Insights

Human sparganosis, a zoonotic infection, is sporadic in Thailand. Most cases present as superficial ocular lesions, with contaminated water being the primary risk factor.

Area of Science:

  • Parasitology
  • Infectious Diseases
  • Tropical Medicine

Background:

  • Sparganosis is a zoonotic parasitic infection occasionally seen in humans.
  • It is reported globally but is most prevalent in East Asia.
  • In Thailand, sparganosis cases are sporadic.

Purpose of the Study:

  • To investigate the clinical presentations of human sparganosis cases in Thailand.
  • To identify common risk factors associated with sparganosis in the region.

Main Methods:

  • A comprehensive literature review was conducted.
  • Clinical data from reported human sparganosis cases in Thailand were analyzed.

Main Results:

  • Thirty-four cases of human sparganosis were identified.
  • Ocular (17 cases) and subcutaneous (10 cases) infections were most common.
  • Drinking contaminated water was the major reported risk behavior.

Conclusions:

  • Superficial ocular mass lesions are the most frequent presentation of sparganosis in Thailand.
  • Contaminated water consumption is the primary risk factor.
  • Deep visceral and central nervous system sparganosis cases, though less common, have been reported.

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...
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...
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...

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...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Symbiosis00:58

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
