Summary
A heterosexual male with a sore throat was diagnosed with oral Trichomoniasis vaginalis. This rare oral infection was confirmed via nucleic acid amplification testing (NAAT) and successfully treated with metronidazole.
Area of Science:
- Infectious Diseases
- Otolaryngology
- Sexual Health
Background:
- Oral infections are typically bacterial or viral, with parasitic infections being rare.
- Trichomoniasis vaginalis is a common sexually transmitted infection, usually affecting the urogenital tract.
Observation:
- A heterosexual male presented with a persistent sore throat.
- Standard tests for common throat infections (rapid strep test, throat culture) were negative.
Findings:
- An oropharyngeal swab tested positive for *Trichomonas vaginalis* using a nucleic acid amplification test (NAAT).
- The patient reported recent oral sex with a female partner diagnosed with trichomoniasis.
Implications:
- This case highlights the possibility of oral transmission of *Trichomonas vaginalis* through oral sex.
- Oropharyngeal NAAT is a valuable tool for diagnosing rare oral parasitic infections.
- Prompt diagnosis and treatment with metronidazole are effective for oral trichomoniasis.

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...

01:29Bacterial Phylum Chlamydiae
678
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

01:23Chronic Pharyngitis
13.7K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

953
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
