American Trypanosomiasis

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...

Toxoplasmosis

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...

Trichomoniasis

Trichomoniasis

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.

Amebiasis

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...

Giardiasis

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...

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Clonorchis sinensis infestation: a case report.

Canadian Family Physician Medecin De Famille Canadien

|February 4, 2011

Summary

A refugee developed severe abdominal issues like cholangitis and pancreatitis due to Clonorchis sinensis infection. This highlights the need for ongoing vigilance in diagnosing parasitic infections in immigrants, even after initial screening.

Area of Science:

Tropical Medicine
Infectious Diseases
Gastroenterology

Background:

Clonorchis sinensis is a parasitic liver fluke endemic in East Asia.
Refugee populations may carry endemic diseases not detected during initial screening.
Delayed presentation of parasitic infections can lead to severe complications.

Purpose of the Study:

To report a case of severe Clonorchis sinensis infection presenting months after immigration.
To emphasize the importance of considering parasitic infections in refugees with unexplained gastrointestinal symptoms.
To alert healthcare providers to potential post-arrival disease development.

Main Methods:

Case report of a young female refugee from Indochina.
Clinical presentation of recurring abdominal pain, acute cholangitis, and pancreatitis.

Diagnostic confirmation via stool microscopy revealing Clonorchis sinensis ova.

Main Results:

The patient experienced prolonged abdominal pain before developing acute cholangitis and pancreatitis.
Clonorchis sinensis ova were identified in stool samples, despite previous negative microscopy.
This parasitic infection was linked to the patient's severe gastrointestinal and biliary complications.

Conclusions:

Clonorchis sinensis infection can manifest with significant morbidity years after migration.
Physicians should maintain a high index of suspicion for parasitic diseases in refugee patients.
Post-arrival screening and follow-up are crucial for early detection and management of parasitic infections.
