    Insights

    Congenital Chagas disease presents two histological types, differing in parasite location within host tissues. Trypanosoma cruzi amastigotes were identified in placental tissues, indicating potential vertical transmission routes.

    Area of Science:

    • Pathology
    • Infectious Diseases
    • Parasitology

    Background:

    • Congenital Chagas disease results from vertical transmission of Trypanosoma cruzi.
    • Histopathological characterization is crucial for understanding disease pathogenesis and transmission.

    Purpose of the Study:

    • To define distinct histological types of congenital Chagas disease.
    • To investigate the distribution of Trypanosoma cruzi amastigotes in placental tissues.

    Main Methods:

    • Histological examination of tissues from congenital Chagas disease cases.
    • Identification and localization of Trypanosoma cruzi amastigotes using microscopy.

    Main Results:

    • Two histological patterns were identified: parasites in skeletal/cardiac fibers, and parasites within the reticuloendothelial system, often with giant cells.
    • Placental findings included inflammatory infiltrates and Trypanosoma cruzi amastigotes predominantly in chorionic villi and chorionic plate.

    Conclusions:

    • Congenital Chagas disease exhibits distinct histopathological presentations.
    • The presence of amastigotes in placental tissues highlights the placenta as a key site for Trypanosoma cruzi during vertical transmission.

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

    Leishmaniasis

    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...

    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...

    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...

    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.
