An 83-year-old Japanese woman with dementia presented with multiple pressure ulcers and cellulitis. At presentation, numerous white maggots were wriggling in the stool on the diaper. Interview to the family revealed that the patient received inappropriate home care due to her dementia and her primary caregiver's developmental disability. No further maggots were omitted after admission, and she was diagnosed with intestinal myiasis. Intestinal myiasis has become rare in developed countries especially in adults. However, elderly bedridden patients living in poor hygiene conditions are at a greater risk of developing intestinal myiasis.

Article Synopsis
- Brevibacillus laterosporus is a type of bacteria known for its potential use as a biopesticide due to its ability to harm various insect species, particularly those that affect human and animal health.
- The study aimed to investigate the effects of this bacterium on M. domestica (house flies) and C. megacephala (blow flies) by examining their larvae and adults after exposure to different concentrations of the bacteria.
- Results showed that B. laterosporus caused significant damage to the intestinal cells of the flies, including irregular microvilli and cellular disorganization, indicating its promise as an eco-friendly insecticide alternative.
Systemic T17 infection in a free-ranging two-toed sloth: case report and literature review of infections by free-living amebas in mammals.

A free-ranging, adult female two-toed sloth () was brought to a wildlife rescue center in Costa Rica with ocular and auricular myiasis and numerous skin lesions. After one month of unsuccessful systemic and topical antimicrobial treatment, the patient died. A postmortem examination was performed, and tissues were examined histologically, confirming disseminated amebic infection with intralesional trophozoites and cysts in the lungs, liver, eye, heart, spleen, and stomach.

We report a case of a suspected intestinal myiasis of a child from Southeast Argentina. Diptera larvae were sampled by a physician from the nappy worn by the child and submitted for examination and identification to the Laboratorio de Artrópodos (Universidad Nacional de Mar del Plata). Based on diagnosis of the anterior and posterior spiracles and mouthparts, the larvae were identified as the false stable fly (Fallén, 1817) (Diptera: Muscidae).

A 75-year-old man with type 2 diabetes and a history of previous empyema surgery was admitted to our hospital due to difficulty moving caused by chronic obstructive pulmonary disease and dehydration. During the first two days of hospitalization, intestinal myiasis was diagnosed after maggots were found in his diapers. After the maggots disappeared, he developed a fever, prompting antibiotic therapy for a suspected secondary infection, resulting in clinical improvement.

Several psychodid flies are commonly associated with human-inhabited environments and have been increasingly implicated in cases of human myiasis. However, the basic biology of psychodid larvae is not well-suited for survival in the human intestinal or urogenital tract, making true, prolonged myiasis unlikely. In this review, we performed a systematic literature review of published cases of purported myiasis caused by psychodid flies, their identification, associated clinical findings, and treatment.
