RESUMO
BACKGROUND: Myiasis, as defined by the Centers for Disease Control and Prevention, is infection with fly larvae commonly occurring in tropical and subtropical areas. Whereas the presentation of skin infection with organisms such as Dermatobia hominis (human botfly) is more easily recognized in these regions, identification of myiasis in the United States is difficult due to its rarity. Due to unspecific signs and symptoms, myiasis may initially be mistaken for other conditions, like cellulitis. CASE REPORT: This case details a patient with pain, swelling, drainage, and erythema of the right second toe. The patient recently returned from Belize and reported an insect bite to the area approximately 1 month prior. She had been seen by health care professionals twice prior to presenting to our Emergency Department (ED) due to increasing pain. At those visits, the patient was prescribed antibiotics, failing to improve her symptoms. In the ED, point-of-care ultrasound (POCUS) of the soft tissue was performed and showed evidence of a foreign body consistent with cutaneous myiasis. Given the patient's history of travel to Belize and known insect bite, it is prudent to have an increased suspicion for cutaneous myiasis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: To prevent a delay in diagnosis and unnecessary antibiotics, clinicians should have a high level of suspicion for botfly if a patient reports recent travel in an endemic region and pain disproportionate to an insect bite. POCUS contributes to a more efficient recognition of the disease.

Two individuals of the jaguar, Panthera onca (L.), were captured near the municipality of Presidente Figueiredo, Brazilian Amazon, during the years of 2017 and 2018. The jaguars presented furuncular myiasis caused by the human botfly Dermatobia hominis (L.) on the rear thighs and tail. This is the first record of infestation of D. hominis in P. onca in the Amazon region.

Dermatobia hominis, commonly known as the human botfly, is native to Tropical America. As such, cutaneous infestation by its developing larvae, or myiasis, is quite common in this region. The distinct dermatological presentation of D hominis myiasis allows for its early recognition and noninvasive treatment by locals. However, it can prove quite perplexing for those unfamiliar with the lesion's unique appearance. Common erroneous diagnoses include the following: folliculitis, benign dermatocyst, and embedded foreign body with localized infection. We present a patient who acquired D hominis while she was in Belize. In this report, we discuss the presentation, differential diagnosis, diagnostic tests, and therapeutic approaches of human botfly lesion to raise the awareness about human botfly.
RESUMO
We found 4 species of mosquitoes bearing eggs of the human botfly, Dermatobia hominis, in the Reserva Municipal de Trabiju, Pindamonhangaba, São Paulo, Brazil. The mosquitoes were simultaneously collected in landingbiting catches by 2 collectors. From a total of 6,902 specimens collected from January through April 2010, the 15 females carrying D. hominis eggs belonged to Aedes scapularis, Limatus durhamii, Onirion personatum, and Wyeomyia confusa. The first 3 species are new reports of phoresy among mosquitoes and the human botfly...

Objective: the finding of Sarcopromusca pruna as a phoretic for Dermatobia hominis eggs is described here. The later is a frequent cattle ectoparasite (human botfly) known as "nuche" in Colombia. Methods: the phoretic flies were captured in a village at San Rafael municipality (Antioquia) using Malaise-typetraps installed during the months of June to August, 2004. Each Sarcopromusca specimen carried a minimum of 19 and, in some cases, up to 23 eggs of D. hominis on the right or left side of the abdominal region. Results and conclusion:This is a new report of Sarcopromusca pruna behaving as a phoretic fly for Dermatobia hominis eggs observed in Colombia.
Objetivo: Se describe el hallazgo de Sarcopromusca pruna (S. pruna) como forético de huevos Dermatobia hominis (D. hominis) ectoparásito comúnmente conocido en Colombia como "nuche". Metódo: las moscas foréticas fueron capturadas en una vereda del municipio de San Rafael (Antioquia) usando trampas de intercepción tipo Malaise instaladas durante los meses de junio a agosto de 2004. Cada espécimen de Sarcopromusca transportaba un número mínimo de 19 y en algunos casos hasta 23 huevos de D. hominis en el lado derecho o en el izquierdo de la región abdominal. Resultados y conclusión: este es un nuevo reporte de S. pruna como forético de huevos de Dermatobia hominis en Colombia.
Objetivo: relatamos a descoberta de Sarcopromusca pruna (S. pruna) como forético dos ovos de Dermatobia hominis (D. hominis), ectoparasita comumente conhecido na Colômbia como "nuche" e no Brasil como "mosca-varejeira". Métodos: as moscas foréticas foram capturadas no município de San Rafael (Antioquia), utilizando armadilhas de intercepção tipo Malaise instaladas durante os meses de junho a agosto de 2004. Cada espécime Sarcopromusca carregava entre 19 e 23 ovos de D. hominis no lado direito ou esquerdo da região abdominal. Resultados y conclusões: este é um novo reporte da S. pruna como forético de ovos de Dermatobia hominis na Colômbia.
