First record of Psorophora ferox (Diptera: Culicidae) infested with eggs of Dermatobia hominis (Diptera: Cuterebridae), in Ucayali: Peru.

INTRODUCTION: Dermatobia hominis belongs to the Cuterebridae family, Diptera order; These flies inhabit tropical regions where they are called "fly of death" since the larvae are capable of causing lesions in domestic animals, wild animals including humans, the adult females of D. hominis capture other dipteran to oviposit their eggs on them (phoresis), when hematophagous mosquitoes land on an animal and / or human in order to feed on their blood, the eggs hatch and the larvae immediately penetrate the skin where they will develop to later abandon the host, then in the soil and / or other moist substrate the pupal stage develops, finally new adult flies will emerge from the pupae. OBJECTIVE: The primary goal of the present study was to determine as first record, the presence of Psorophora ferox infested with eggs of Dermatobia hominis, Peru. METHODOLOGY: The present study was carried out in an area of the private reserve "El Vencedor", located within the city of Pucallpa, Ucayali Region-Perú. The area is characterized by being humid tropical, with an average temperature of 26ºC and humidity of 92%, while the annual precipitation is approximately 1570 mm3. The capture method was carried out with the help of a hand net type "butterfly" or also called Jama. RESULTS: A total of 668 mosquitoes of different species were collected, the most abundant being Psorophora albigenu and Psorophora ferox, which represented 88.72% and the least abundant was Culex coronator and Uranotaenia apicalis with 0.15% of the total sample collected. CONCLUSIONS: Within these specimens it was captured a mosquito of the species Ps. ferox with the presence of 8 eggs of D. hominis, of which 3 would have hatched, while in the remaining 5, the larvae would remain inside the eggs.

Cerebral Myiasis, An Unexpected Intraoperative Finding - A Case Report and Systematic Review.

Postoperative complications, exemplified by surgical site infections, are commonplace in the realm of daily surgical interventions. Conversely, certain infectious entities, such as cerebral myiasis (CM), are distinctly rare. This report elucidates the clinical presentation of a 74-year-old female afflicted with a CSF fistula, within the context of a preceding surgical microvascular decompression employing a suboccipital craniotomy approach. Notably, the course of evaluation and treatment unveiled an intraoperative manifestation of severe CM. This case report underscores the critical significance of prompt identification, precise diagnostic elucidation, and comprehensive multidisciplinary management to optimize patient outcomes in instances of CM. Furthermore, a systematic literature review on CM supplements this report, contributing to the understanding of this infrequent complication.

Imaging features for the evaluation of skin and nail infections.

Clinical manifestations of dermatological and musculoskeletal conditions can sometimes overlap, leading to confusion in diagnosis. Patients with nail and skin infections may undergo imaging examinations with suspicions of muscle, tendon, or joint injuries. Dermatological infections often involve soft tissues and musculoskeletal structures, and their etiology can range from fungi, bacteria, viruses, to protozoa. Relying solely on physical examination may not be sufficient for accurate diagnosis and treatment planning, necessitating the use of complementary imaging exams. The objective of this paper is to present and discuss imaging findings of the main infectious conditions affecting the nail apparatus and skin. The paper also highlights the importance of imaging in clarifying diagnostic uncertainties and guiding appropriate treatment for dermatological conditions.

Ophthalmomyiasis Externa and Importance of Risk Factors, Clinical Manifestations, and Diagnosis: Review of the Medical Literature.

OBJECTIVE: This review aims to describe and compare the risk factors, clinical course, diagnosis, and parasitologic features of external ophthalmomyiasis. We also discuss the different preventive measures and the effect of global warming in a large case series reported from January 2000 to December 2022. METHODS: We perform a literature review of reported cases of external ophthalmomyiasis to determine the clinical characteristics, therapeutic management, and information on the organisms that most commonly cause external ophthalmomyiasis. RESULTS: A total of 312 cases of external ophthalmomyiasis were recorded. The most common causative organism was Oestrus ovis (Linnaeus) (Diptera: Oestridae), accounting for 72.1% of cases, followed by Dermatobia hominis (Linnaeus Jr. in Pallas, 1781) (Diptera: Oestridae) at 5.4%, Lucilia sericata (Meigen) (Diptera: Calliphoridae) at 0.96%, and Chrysomyia bezziana (Villeneuve) (Diptera: Calliphoridae) at 0.96%. Before experiencing symptoms, 43.6% of cases reported having direct contact with flies or being hit in the eye, 33% reported no associated risk factors, 9.3% reported living with sheep and goats, and 7.7% reported a history of foreign objects entering the eye. The most common symptoms for those affected by O. ovis were sudden onset, including a foreign body sensation and movement, redness, tearing, itching, swelling, irritation, photophobia, burning, and ocular secretion. In cases caused by D. hominis, symptoms included eyelid edema, pain, redness, itching, movement within the lesion, ocular irritation, and discharge. Regarding occupational or recreational activity, agriculture, and livestock had the highest incidence, followed by trades and technical activities, being a student, and having traveled to an endemic region for work or recreation. CONCLUSION: Patients with red eyes may suffer from external ophthalmomyiasis, which requires a thorough examination to diagnose and treat it early. Moreover, as the temperature increases due to climate change, it is essential to consider how this will affect the spread of different pathogens.

Larvicidal activity in vitro of essential oils against Cochliomyia hominivorax.

Cochliomyia hominivorax, from the family Calliphoridae, is responsible for causing most myiases in domesticated animals in Brazil. As alternatives to conventional treatments, essential oils (EOs) could possibly be used as natural control of ectoparasites. The aim of this study was to evaluate the in vitro activity of EOs from Salvia sclarea L., Rosmarinus officinalis L., Lavandula hybrida Reverchon, Citrus bergamia Risso, Citrus paradisi L., Juniperus virginiana L., Copaifera reticulata Ducke, Illicium verum Hook f., Pelargonium roseum, Cymbopogon winterianus Jowitt, Cymbopogon flexuosus Steud, Eugenia caryophyllus Spreng, Cinnamomum cassia Presl, Thymus vulgaris L. and Origanum vulgare L. against third-instar larvae of C. hominivorax. To evaluate the mortality rate, filter paper tests were performed at different concentrations and verified after 24 h and 48 h. Essential oils of T. vulgaris, O. vulgare and I. verum induced 100% mortality in the screening test, and their main active components (thymol, carvacrol and anethol, respectively) were also tested alone. In this new test, lethal concentrations (LC50) after 24 h and 48 h, respectively, were 407.1 and 314.2 µg.cm-² for T. vulgaris, 540.9 and 253.8 µg.cm-² for O. vulgare, 314.2 µg.cm-² (after 48 h) for I. verum, 255.6 and 102.3 µg.cm-² for thymol, 970.5 and 931.1 µg.cm-2 for carvacrol and 559.4 µg.cm-2 (after 48 h) for anethol. These results showed the potential of these EOs and their main components for development of ectoparasiticides for veterinary use, especially T. vulgaris EO and thymol.

Morphological and Molecular Characterizations of Cochliomyia hominivorax (Diptera: Calliphoridae) Larvae Responsible for Wound Myiasis in French Guiana.

Myiasis is an ectoparasitic infection caused by the larvae of true flies (Diptera). We came across a rather rare case of myiasis in an immunocompetent 34-year-old man from French Guiana with advanced wound myiasis masquerading as cavitary myiasis and a history of cholesteatoma surgery in the left ear. The Diptera larvae responsible for the disease were isolated and identified using morphological and molecular approaches as Cochliomyia hominivorax. We underline the importance of this parasitosis as the second case of myiasis caused by C. hominivorax and the first case of wound myiasis in this overseas department of France and its incidence in pre-urban areas of the capital, Cayenne, in South America.

Myiasis on the tongue of a patient hospitalized in a psychiatric ward: A case report with a focus on diagnosis and clinical management.

INTRODUCTION: Myiasis is a disease caused by the infestation of fly larvae in the skin, which complete part of their life cycle by feeding on host tissues. OBJECTIVE: To report a rare case of tongue myiasis in a patient admitted to a psychiatric ward, focusing on clinical management. CASE REPORT: A dependent care and mentally challenged 55 years old male patient was hospitalized in a psychiatric ward. After 42 days, during the intraoral examination, it was noted numerous larvae peeking from inside of a wound on the dorsum of the tongue. The clinical diagnosis of myiasis was rendered. For the treatment, manual removal was performed initially and ivermectin (15 mg), metamizole sodium (500 mg/ml), and chlorhexidine digluconate (0.12%) were prescribed. After one week, larvae were no longer observed, and the wound was completely healed. CONCLUSION: Myiasis occurrence is uncommon in the mouth, however, its correct diagnosis and treatment are necessary to avoid further damage to patients, especially those who are hospitalized.

First record of a rare case of accidental urinary myiasis by Telmatoscopus albipunctata (Diptera: Psychodidae), with morphological description, in a human in Brazil.

Telmatoscopus albipunctata is an insect of the Psychodidae family, with a worldwide distribution, particularly in tropical and subtropical countries. Although it does not have hematophagous habits, it has veterinary medical importance due to the mechanical transmission of protozoa and bacteria, many of which cause nosocomial infections. This dipteran has been reported as one of the causative agents of accidental myiasis in humans in several countries, and since it has not been registered in South America, the objective of the present report was to describe a rare case of accidental urinary myiasis caused by T. albipunctata (Diptera: Psychodidae) in humans in Brazil. In the present report, a 25-year-old female patient, resident of the central region of the state of Rio Grande do Sul, Brazil, sought medical attention after finding larvae in her urine. She complained of vaginal itching and skin dermatitis. The larvae were sent to the Veterinary Parasitology Laboratory of the Federal University of Santa Maria, where they were mounted on permanent slides for further taxonomic identification. Morphological characteristics allowed the identification of fourth-stage larvae and pupae of T. albipunctata. Therefore, the present work reports the first record of accidental urinary myiasis caused by T. albipunctata infection in Brazil and South America.

Efficacy of lotilaner against myiasis caused by Cochliomyia hominivorax (Diptera: Calliphoridae) in naturally infested dogs.

BACKGROUND: The New World screwworm fly, Cochliomyia hominivorax, is widely distributed across South America. This parasitic insect is a significant cause of primary myiasis in animals, including dogs. There is an urgent need for a rapid and efficient treatment to improve the recovery of affected animals. In the present study we evaluated the potential of lotilaner for the treatment of myiasis caused by C. hominivorax larvae in naturally infested dogs. Lotilaner belongs to the isoxazoline class of chemical compounds and is marketed as Credelio™ for use against ticks and fleas in dogs and cats. METHODS: Eleven dogs with naturally acquired myiasis were enrolled in this study based on the severity of lesions and the number of identified larvae. All animals received a single oral administration of lotilaner at a minimum dose of 20.5 mg/kg body weight. After treatment, the number of expelled larvae, live or dead, was determined at 2, 6 and 24 h, and the larval expulsion rate, larvicidal effect and overall efficacy were calculated. After 24 h, the remaining larvae were removed, counted and identified. The lesions were cleaned, and palliative treatment was administered when necessary, according to the animal's health status. RESULTS: All larvae were identified as C. hominivorax. The larval expulsion rate was 80.5% and 93.0% at 2 and 6 h post-treatment, respectively. Lotilaner showed an overall efficacy of 100% at 24 h post-treatment. CONCLUSIONS: Lotilaner demonstrated a rapid onset of action and a high efficacy against C. hominivorax. We therefore recommend lotilaner for the effective treatment of myiasis in dogs.

Orbital ophthalmomiasis due to Dermatobia hominis in an immunosuppressed patient from the ecuadorian andean area.

An 83-year-old Ecuadorian male, indigent with a history of malnutrition and chronic alcoholism, presented with a clinical feature characterized by progressive growth of larvae at the left eye level (LE), associated with areas of ocular tissue putrefaction. Upon admission, his vision in the right eye (RE) was of hand movement and no light perception in LE, the anterior segment of the RE showed a brunescent cataract, with no other alteration, while the LE presented edema, bipalpebral erythema and an abundant number of mobile larvae distributed throughout the orbit, associated with areas of necrosis, putrefaction and distortion of the anatomy of the ocular tissues. Orbital tomography showed a significant compromise of the orbit, indicating surgical management by left orbital exenteration with taxonomic identification of the larvae as Dermatobia hominis associated with it, antibiotic treatment was implemented and a frontal fasciocutaneous flap was performed by the plastic surgery department.

Treatment of oral myiasis in a patient with implant-supported fixed prosthesis

ABSTRACT Oral myiasis is a rare parasitic disease that requires immediate treatment once diagnosed. However, no standard treatment protocol can be found in the literature. Through a clinical-surgical report, we present the case of an 82-year-old man with lesions extending through the vestibule and alveolar ridge of the maxilla on both sides, in addition to occupying a large part of the palate, with a considerable number of larvae. The patient was initially treated with a single dose of systemic ivermectin (6 mg orally) and topical application of a tampon soaked in ether. The larvae were then surgically removed and debridement of the wound was performed. A crushed tablet of ivermectin 6 mg was applied topically for 2 days, the remaining larvae were again mechanically removed, and the patient received intravenous antimicrobial therapy. Treatment with systemic and topical ivermectin combined with antibiotic therapy and debridement proved to be effective in treating oral myiasis.

Actinomycotic Osteomyelitis and Myiasis in Oroantral Communication: Clinicopathological and Tomographic Findings

Actinomycotic osteomyelitis of the maxilla presenting with oroantral communication is very rare, herein we report the first case of this condition in association with myiasis. A 50-year-old man reported chronic sinusopathy and a non-healing maxillary lesion, with 30 years of evolution, presenting occasional nasal and intraoral purulent discharge, with foul smell, and recurrent episodes of larvae presence. Cone beam computed tomography showed a large hyperdense image inside the left maxillary sinus, with focal areas with soft tissue density, and extensive discontinuity of the maxillary sinus floor, confirming the oroantral fistula. The necrotic tissue curetted during surgery presented hard consistency, and dark greenish color, and was submitted for histopathological analysis. Microscopically, necrotic bone, masses of filamentous bacteria colonie s, compatible with actinomycosis, and large rhomboidal structures surrounded by eosinophilic capsule - suggestive of larvae, were observed. The diagnosis of actinomycotic osteomyelitis with presence of structures compatible with larvae was established.

La osteomielitis actinomicótica del maxilar que se presenta con comunicación oroantral es poco frequente. En este trabajo reportamos el primer caso de esta condición en asociación con miasis. Un hombre de 50 años que refiere sinusopatía crónica y lesión maxilar que no cicatriza, de 30 años de evolución, presenta secreción ocasional purulenta nasal e intraoral, con mal olor y episodios recurrentes de presencia de larvas. La tomografía computarizada de haz cónico mostró una gran imagen hiperdensa en el interior del seno maxilar izquierdo, con áreas focales con densidad de partes blandas y una extensa discontinuidad del piso del seno maxilar, lo que confirma la fístula oroantral. El tejido necrótico legrado durante la cirugía presentó consistencia dura, coloración verdosa oscura, y fue remitido para análisis histopatológico. Microscópicamente se observó hueso necrótico, masas de colonias de bacterias filamentosas compatibles con actinomicosis y grandes estructuras romboidales rodeadas de cápsula eosinofílica sugestiva de larvas. Se estableció el diagnóstico de osteomielitis actinomicótica con presencia de estructuras compatibles con larvas.

Miasis Genital. Presentación de un caso

Introducción: la miasis se define como la infestación de animales domésticos y salvajes, así como del hombre por estados larvarios de varias especies de dípteros que se alimentan de tejidos vivos o muertos o del alimento ingerido por el hospedero. Puede encontrarse en genitales, extremidades, cráneo, boca y párpados. Presentación de caso: se presenta el caso de un paciente, masculino de procedencia rural de 56 años de edad. Acude remitido de su área de salud por presentar varias ulceras a nivel del pene acompañado de aumento de volumen del mismo con secreciones fétidas, prurito y dolor. Se ingresa para estudio y tratamiento en sala. Se le diagnosticó miasis genital a nivel del glande. Tuvo una evolución satisfactoria en sala mediante curas locales y el tratamiento con antimicrobianos. Discusión: la miasis genital es poco común, probablemente por el aislamiento que ejerce la ropa al contacto con las moscas, sin embargo, la vestimenta corta predispone una mayor ovoposición en esta zona debido a una exposición más asequible, puede imitar lesiones inflamatorias o ulcerosas. De hecho, esta infestación parasitaria se ha asociado con determinadas enfermedades urogenitales de aspecto tumoral. Conclusiones: indiscutiblemente la inadecuada higiene de los genitales es un factor determinante en la aparición de la miasis.

Introduction: myiasis is defined as the infestation of domestic and wild animals, as well as man, by larval stages of various species of Diptera that feed on living or dead tissue or food ingested by the host. Genital myiasis is rare, of which there is little reference in the literature, specifically in the Caribbean. Case report: the case of a 56-year-old male patient of rural origin is presented. He was referred from his health area for presenting several ulcers on the penis accompanied by an increase in its volume with fetid secretions, itching and pain. He is admitted for study and treatment in the room. He was diagnosed with genital myiasis at the level of the glans. He had a satisfactory evolution in the room through local cures and treatment with antimicrobials. Discussion: genital myiasis is uncommon, probably due to the insulation exerted by clothing in contact with flies, however, short clothing predisposes a greater oviposition in this area due to more accessible exposure, it can mimic inflammatory or ulcerative lesions. In fact, this parasitic infestation has been associated with certain tumor-like urogenital diseases. Conclusions: unquestionably, inadequate genital hygiene is a determining factor in the appearance of myiasis.

Introdução: amiíase é definida como a infestação de animais domésticos e silvestres, assim como o homem, por fases larvais de várias espécies de Diptera que se alimentam de tecidos vivos ou mortos ou alimentos ingeridos pelo hospedeiro. Pode ser encontrado nos genitais, extremidades, crânio, boca e pálpebras. Apresentação do caso: apresenta-se o caso de um paciente do sexo masculino, 56 anos, de origem rural. Foi encaminhado de sua área de saúde por apresentar várias úlceras no pênis acompanhadas de aumento do seu volume com secreções fétidas, prurido e dor. Ele é admitido para estudo e tratamento na sala. Foi diagnosticado com miíase genital ao nível da glande. Teve evolução satisfatória na sala através de curas locais e tratamento com antimicrobianos. Discussão: amiíase genital é incomum, provavelmente devido ao isolamento exercido pelas roupas em contato com moscas, entretanto, roupas curtas predispõem uma maior oviposição nesta área devido à exposição mais acessível, podendo mimetizar lesões inflamatórias ou ulcerativas. De fato, essa infestação parasitária tem sido associada a certas doenças urogenitais semelhantes a tumores. Conclusões: inquestionavelmente, a higiene genital inadequada é um fator determinante no aparecimento da miíase.

Severe Vaginal Myiasis: Successful Management With Ivermectin.

Myiasis refers to infestation of living animals or humans by maggots or fly larvae. Urogenital myiasis is a rare condition that is linked to poor sanitary conditions and limited access to healthcare and with few published case reports. Here, we describe the case of a 67-year-old homeless woman with multiple comorbidities, who presented with extensive vaginal myiasis requiring inpatient management with ivermectin, ceftriaxone, and metronidazole and daily larvae extraction and debridement. The relevance of this case is providing a report of a successful management with ivermectin of a case of severe vaginal myiasis. Severe cases of vaginal myiasis can require repeated debridement of necrotic tissue and systemic antibiotics in addition to antiparasitic medication. People living under poor sanitary conditions and with poor hygienic practices are at increased risk for severe vaginal myiasis.

Botfly Parasitism on Two Primates of the Cebidae Family in Peru.

Botflies (Diptera:Oestridae) are a diverse group of insect parasites that affect various vertebrate species. There are previous reports of myiasis affecting wild primates in Central and South America; however, information about botfly parasitism in Peruvian primates is scarce. We present data from two Cebidae primate specimens: a rescued large-headed capuchin monkey (Sapajus macrocephalus) housed at Taricaya Rescue Center, in Tambopata, Peru, and a free-ranging white-fronted capuchin monkey (Cebus albifrons aequatorialis) inhabiting Cerros de Amotape National Park. The first specimen had a larva identified as Dermatobia hominis, whereas Cuterebra baeri larvae infested the second. In both cases we initially identified the parasite species through their morphologic features before confirming the identification with genetic analysis through the cytochrome C oxidase subunit 1 mitochondrial gene sequencing of the larvae. Further field studies on the primate-parasite dynamics are needed to understand the impact of botfly myiasis on primate populations.
