“…The removal of the parasite through surgery is the preferred treatment for live cases, given the risk of migration in mobile worms [8]. However, it is important to note that dead parasites may not elicit any inflammation and may be well-managed through observation.…”

This report presents a rare case of a 25-year-old man with a Taenia solium worm found under the conjunctiva of his left eye. The patient had experienced redness, pain, itching, and epiphora in the affected eye. Subsequent examination revealed conjunctival congestion and a moving whitish linear formation, which was diagnosed as subconjunctival ocular parasitosis. The patient underwent successful surgical removal of the parasite and recovered without complications. The report highlights the importance of early diagnosis and prompt treatment to prevent permanent vision loss in cases of ocular parasitosis.

Ocular cysticercosis is a preventable cause of blindness. It is a parasitic infestation caused by Cysticercus cellulosae—which is the larval form of Taenia solium. In 1829, Soemmering reported the first case of a live anterior chamber cysticercosis. In the following, we report a rare case of a 13-year-old male who presented with a live adult Taenia solium in the anterior chamber without any systemic features and its successful management.

“…For instance, cerebral sparganosis can lead to diverse neurological symptoms, such as fatigue, headache, seizures, and hemiparesis [7,8,9,10]. In cases where sparganum infests the eyes, it can cause periorbital edema, protrusion of the eyeball, orbital cellulitis, and corneal ulceration, potentially resulting in blindness if left untreated [11,12,13,14]. Spirometra sp.…”

Background The plerocercoid larvae of Spirometra mansoni (S. mansoni) can invade the human body, causing a severe parasitic zoonotic disease known as sparganosis. Methods To gain insights into the developmental process of S. mansoni, it is crucial to comprehend the specific gene and protein expressions that allow the parasite to adapt to environmental changes between intermediate and definitive hosts. In this study, we employed tandem mass tag (TMT) analysis to compare proteomic changes among three developmental stages of S. mansoni: the egg, sparganum, and adult stages. Results We identified significant differential expression in a total of 1730 proteins in the sparganum compared to the egg groups and 1308 proteins in the adult compared to the sparganum groups. The functional annotation of these differentially expressed proteins (DEPs) unveiled pronounced metabolic disparities among these developmental stages. The sparganum stage exhibited overexpression of proteins primarily linked to migration and immune evasion, which underpins its potent immune escape mechanism and robust invasion capabilities. In contrast, the adult stage displayed an upregulation of proteins associated with functions related to protein biosynthesis, including translation, peptide biosynthetic processes, amide biosynthetic processes, and peptide metabolic processes. Conclusions These findings highlight new insights into the proteomic changes across S. mansoni developmental stages, potentially offering valuable targets for diagnosis and therapy.
