"Myiasis" is considered in Hindu mythology as "God's punishment for sinners". Literature abounds with reports of myiasis affecting the nasal cavity, ear, non healing ulcers, exophytic malignant growth and cutaneous tissue. But case report of myiasis of the tracheostomy wound is relatively rare and that also peristomally is seen first time. We are reporting two cases whose tracheostomy was done, one for laryngeal cancer and other for laryngocoele. We are discussing the need for the proper care of tracheostomy wound myiasis because the site of such an infestation is close to vital organs in the neck and avoiding complications.

BACKGROUND
Feral swine (Sus scrofa) are highly invasive and threaten animal and human health in the Americas. The screwworm (Cochliomyia hominivorax) is listed by the World Organization for Animal Health as a notifiable infestation because myiasis cases affect livestock, wildlife, and humans in endemic areas, and outbreaks can have major socioeconomic consequences in regions where the screwworm has been eradicated. However, a knowledge gap exists on screwworm infestation of feral swine in South America, where the screwworm is endemic. Here, we report screwworm infestation of feral swine harvested in Artigas Department (Uruguay), where the Republic of Uruguay shares borders with Brazil and Argentina.
METHODS
Myiasis caused by the larvae of screwworm were identified in feral swine with the support and collaboration of members of a local feral swine hunting club over a 3-year period in the Department of Artigas. Harvested feral swine were examined for the presence of lesions where maggots causing the myiasis could be sampled and processed for taxonomic identification. The sites of myiasis on the body of infested feral swine and geospatial data for each case were recorded. The sex and relative size of each feral swine were also recorded. Temperature and precipitation profiles for the region were obtained from public sources.
RESULTS
Myiases caused by screwworms were recorded in 27 of 618 the feral swine harvested. Cases detected in males weighing > 40 kg were associated with wounds that, due to their location, were likely caused by aggressive dominance behavior between adult males. The overall prevalence of screwworm infestation in the harvested feral swine was associated with ambient temperature, but not precipitation. Case numbers peaked in the warmer spring and summer months.
CONCLUSIONS
This is the first report on myiasis in feral swine caused by screwworm in South America. In contrast to myiasis in cattle, which can reach deep into host tissues, screwworms in feral swine tended to cause superficial infestation. The presence of feral swine in screwworm endemic areas represents a challenge to screwworm management in those areas. Screwworm populations maintained by feral swine may contribute to human cases in rural areas of Uruguay, which highlights the importance of the One Health approach to the study of this invasive host species-ectoparasite interaction.

In this study, we developed a bioadhesive emulsion-filled gel containing a high amount of Ducke oil-resin as a veterinary or human clinical proposal. The phytotherapeutic system had easy preparation, low cost, satisfactory healing ability, and fly repellency, making it a cost-effective clinical strategy for wound care and myiasis prevention. Mechanical, rheological, morphological, and physical stability assessments were performed. The results highlight the crosslinked nature of the gelling agent, with three-dimensional channel networks stabilizing the Ducke oil-resin (CrD-Ore). The emulgel presented antimicrobial activity, satisfactory adhesion, hardness, cohesiveness, and viscosity profiles, ensuring the easy spreading of the formulation. Considering dermatological application, the oscillatory responses showed a viscoelastic performance that ensures emulgel retention at the action site, reducing the dosage frequencies. evaluations were performed using a case report to treat ulcerative skin wounds aggravated by myiasis in calves and heifers, which demonstrated healing, anti-inflammatory, and repellent performance for the emulsion-filled gel. The emulgel preparation, which is low in cost, shows promise as a drug for wound therapy.

Review
BACKGROUND
To enhance awareness of the clinical features and prevention of endotracheal myiasis.
CASE PRESENTATION
A case of intratracheal myiasis is reported. A 61-year-old male patient with a history of laryngectomy was admitted to hospital due to tracheostomal hemorrhage of 3 h duration. Intratracheal myiasis was confirmed by bronchoscopy, and the patient underwent bronchoscopic intervention, which was complicated by a tracheal-esophageal fistula and resolved by endotracheal stenting. Twenty months after stent placement, the fistula had not healed.
CONCLUSION
Intratracheal myiasis has serious complications and is difficult to treat. For post-tracheostomy patients, healthcare providers and caregivers should pay attention to the care and monitoring of wounds and maintenance of a tidy, clean living environment to prevent intratracheal myiasis.

Myiasis is a type of parasitosis by larvae of Diptera that may affect vertebrates, including wild and domestic birds. Traumatic myiasis was discovered in a domestic goose, L. (Anseriformes: Anatidae), in June 2020 in a rural area of the region Calabria (Southern Italy). The myiasis was caused by (Meigen) (Diptera: Calliphoridae). In Italy, this was the first case of myiasis by ever described in a bird. It was also the first case of myiasis detected in a goose in Italy. The description of the case is integrated by a discussion on nonhematophagous dipteran larvae causing myiasis in birds and by an updated and detailed review of literature cases of myiasis by in birds reported worldwide, useful for monitoring and management of dipteran species of medical and veterinary interest.

Review
Ivermectin has emerged as a therapeutic option for various parasitic diseases, including strongyloidiasis, scabies, lice infestations, gnathostomiasis, and myiasis. This study comprehensively reviews the evidence-based indications for ivermectin in treating parasitic diseases, considering the unique context and challenges in Peru. Fourteen studies were selected from a systematic search of scientific evidence on ivermectin in PubMed, from 2010 to July 2022. The optimal dosage of ivermectin for treating onchocerciasis, strongyloidiasis, and enterobiasis ranges from 150 to 200 μg/kg, while lymphatic filariasis requires a higher dose of 400 μg/kg (Brown et al., 2000). However, increased dosages have been associated with a higher incidence of ocular adverse events. Scientific evidence shows that ivermectin can be safely and effectively administered to children weighing less than 15 kg. Systematic reviews and meta-analyses provide strong support for the efficacy and safety of ivermectin in combating parasitic infections. Ivermectin has proven to be an effective treatment for various parasitic diseases, including intestinal parasites, ectoparasites, filariasis, and onchocerciasis. Dosages ranging from 200 μg/kg to 400 μg/kg are generally safe, with adjustments made according to the specific pathology, patient age, and weight/height. Given Peru's prevailing social and environmental conditions, the high burden of intestinal parasites and ectoparasites in the country underscores the importance of ivermectin in addressing these health challenges.

Frequency and prevalence of clinical conditions and therapeutic drugs used in dog and cat at Teaching Veterinary Hospital, Chattogram Veterinary and Animal Sciences University.
OBJECTIVE
This study was carried out to determine the frequency and prevalence of clinical conditions and their treatment, especially antibiotics in dogs and cats.
MATERIALS AND METHODS
A period of 12-month retrospective study was conducted at the Teaching Veterinary Hospital, Chattogram Veterinary and Animal Sciences University, Chittagong, Bangladesh from July 2018 to June 2019. A total of 849 cases, including 488(57.5%) and 361 (42.5%) dogs and cats respectively, were in account to espy the clinical conditions. Season, age, sex, and breed were the parameters to analyze the prevalence of those clinical conditions.
RESULTS
From the study, it was found that the endoparasitic infestation was highly frequent in both dog and cat (55% in dogs and 59% in cats). The endoparasitic infestation was highly prevalent in cats (91.53%) significantly ( = 0.003), which were ≤1 year of age. On the other hand, the ectoparasitic infestation was found prevalent significantly ( = 0.06) in the winter than any season and dewormed dogs ( = 0.03). Prevalence of canine parvovirus infection in dogs and wound in cats were substantially higher ( < 0.001 and =0.05 respectively) in the winter whereas the prevalence of myiasis in dogs was prominent in the rainy season significantly ( 0.01). The mostly used antibiotic was ceftriaxone (9.5% in dogs and 4% in cats).
CONCLUSION
Different endoparasitic, ectoparasitic, and infectious diseases found prone to infect pet animals, mainly dogs, and cats. By maintaining proper anthelmintics and vaccine shots may act as a prevention procedure to those infections.

BACKGROUND
Myiasis by (Diptera: Calliphoridae) is a serious problem in animal health in tropical and sub-tropical regions. Ointment-type preparations are a good option of formulation in cases of myiasis in farm and pet animals. and have already shown efficacy on . This article describes an experiment to test the inhibition of development from exposing larvae of to two homeopathic ointments (prepared individually with or ).
METHODS
The homeopathic ointments were produced by mixing sterile lanolin, tocopherol and homeopathic medicine on a hydroalcoholic basis according to the Brazilian Homeopathic Pharmacopoeia. Larvae were obtained from naturally occurring myiases in sheep (wild larvae) or from a laboratory colony. The test consisted of exposing a group of 10 third-stage wild larvae in contact with or ointment, or a group of 15 laboratory-propagated larvae in contact with the alcoholic vehicle of the ointment or homeopathic medicines prepared in sterile water ( or ), and observing the effect on the development, longevity and fertility of the blow-fly specimens.
RESULTS
The larval inhibition rate was 90.0% for the ointment group and was 86.0% for the ointment group. The non-alcoholic vehicle and the alcoholic vehicle inhibited the development of 24.0% and 22.08% of the larvae respectively. prepared in sterile water inhibited the development of 74.67% and in sterile water inhibited 73.33% of larvae. Specimens that survived contact with homeopathic ointments had their longevity decreased and did not reproduce.
CONCLUSION
Ointments of or were able to inhibit the development of larvae. The ointment vehicle was harmless.

Myiasis is a skin infection caused by developing larvae (maggots) of various Diptera fly species. The two most frequent flies that cause human infestations around the world are Dermatobia hominis (human botfly) and Cordylobia anthropophaga (tumbu fly). Maggots have been found to infest the nose, ear, orbit, tracheostomy wound, face, gums, and serous cavities, among other places. Maggots at the colostomy site are an uncommon occurrence. We report a case of maggots infestation surrounding the colostomy site. We came across a rather rare finding in a patient with advanced inoperable rectum cancer who initially complained of persistent nonspecific pain, discomfort, and foul-smelling discharge from the colostomy site. The issue at hand was identified to be maggots, and their removal alleviated the patient's symptoms. We underline the importance of regularly monitoring stoma sites to avoid maggot infestation, especially in tropical regions.
