Summary
Tungiasis is a painful skin disease caused by the jigger flea (Tunga penetrans). Diagnosis relies on clinical signs and travel history, with surgical flea removal as the primary treatment.
Area of Science:
- Dermatology
- Parasitology
- Tropical Medicine
Background:
- Tungiasis is a neglected parasitic skin disease prevalent in intertropical regions.
- It is caused by the sand flea, *Tunga penetrans* (jigger flea).
- Infestation occurs through barefoot contact with contaminated soil.
Purpose of the Study:
- To describe the etiology, clinical presentation, diagnosis, and treatment of tungiasis.
- To raise awareness of this common yet often overlooked parasitic infection.
Main Methods:
- Diagnosis is primarily based on clinical observation of characteristic lesions.
- Patient history, including travel to endemic areas, is crucial for diagnosis.
- Microscopic identification of the flea may be used in some cases.
Main Results:
- Lesions typically occur on the feet and present as painful, itchy papules with a central punctum.
- Secondary bacterial infections can complicate untreated tungiasis.
- Surgical extraction of the embedded flea is the standard and effective treatment.
Conclusions:
- Tungiasis is a preventable disease associated with poor sanitation and limited footwear access.
- Early diagnosis and prompt surgical removal of the flea are essential to prevent complications.
- Public health initiatives focusing on prevention and treatment are needed in endemic areas.

01:22American 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...
01:28Toxoplasmosis
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...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:18Trichomoniasis
Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
01:15Diversity 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...
