Summary
Entamoeba histolytica causes amebiasis and can lead to liver abscesses. This case highlights a symptomatic extraintestinal infection in a young bisexual man, noting rising sexual transmission, particularly among men who have sex with men.
Area of Science:
- Infectious Diseases
- Parasitology
- Public Health
Background:
- Entamoeba histolytica is a protozoan parasite causing amebiasis, prevalent in regions with poor sanitation.
- Extraintestinal manifestations, including liver abscesses, can occur.
- Increased emigration has led to a rise in Entamoeba histolytica infections in the United States.
Observation:
- A growing trend of sexual transmission of Entamoeba histolytica has been observed.
- This transmission is most frequently reported among men who have sex with men.
- The study presents a case of symptomatic extraintestinal infection in a young Hispanic bisexual man.
Findings:
- The case details a symptomatic extraintestinal Entamoeba histolytica infection.
- This presentation underscores the potential for diverse clinical manifestations of the parasite.
- The case contributes to understanding the epidemiology of sexually transmitted amebiasis.
Implications:
- Highlights the importance of considering Entamoeba histolytica in sexually active individuals presenting with gastrointestinal or extraintestinal symptoms.
- Emphasizes the need for increased awareness and diagnostic vigilance for amebiasis in diverse populations, including men who have sex with men.
- Informs public health strategies for prevention and control of Entamoeba histolytica transmission, particularly in the context of sexual contact.

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...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

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...

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

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...

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...
