Review
Among arthropod diseases affecting animals, larval infections - myiases - of domestic and wild animals have been considered important since ancient times. Besides the significant economic losses to livestock worldwide, myiasis-causing larvae have attracted the attention of scientists because some parasitise humans and are of interest in forensic entomology. In the past two decades, the biology, epidemiology, immunology, immunodiagnosis and control methods of myiasis-causing larvae have been focused on and more recently the number of molecular studies have also begun to increase. The 'new technologies' (i.e. molecular biology) are being used to study taxonomy, phylogenesis, molecular identification, diagnosis (recombinant antigens) and vaccination strategies. In particular, more in depth molecular studies have now been performed on Sarcophagidae, Calliphoridae and flies of the Oestridae sister group. This review discusses the most topical issues and recent studies on myiasis-causing larvae using molecular approaches. In the first part, PCR-based techniques and the genes that have already been analysed, or are potentially useful for the molecular phylogenesis and identification of myiasis-causing larvae, are described. The second section deals with the more recent advances concerning taxonomy, phylogenetics, population studies, molecular identification, diagnosis and vaccination.

Myiasis has been defined as the infestation of organs and/or tissues with dipterous larvae. They are especially widespread in tropical and subtropical areas. Cutaneous myiasis is its most frequent clinical presentation. This report presents a case of furuncular myiasis caused by the larva of Cordylobia anthropophaga in a 22-year-old girl living in Bergamo, Northern Italy, who returned from Kenya (Watamu) with a big, painful furuncle in her right gluteus. The patient accidentally removed the larva from a large pimple and took it to the infectious disease ambulatory clinic at the ASST "Papa Giovanni XXIII" Hospital, Bergamo. In the Microbiology and Virology Department of the same hospital, a larva of C. anthropophaga was identified and the diagnosis of myiasis was confirmed.

Review
Cutaneous myiasis is seen in travellers returning from the tropics. The flies commonly involved are Cordylobia arthropophaga and Dermatobia hominis. Humans become infected by contact with eggs laid by the female fly on soil or contaminated clothing. The clinical presentation is boil-like skin lesions. Treatment involves asphyxiation of larvae forcing emergence, application of toxic agents or surgical removal.

Myiasis is a parasitic infestation of tissues and body cavities of vertebrates by . Nasal myiasis is mostly caused by the and families. Many predisposing factors play a role in the appearance of nasal myiasis. In the treatment of the disease, the use of antiseptics together with mechanical cleaning is recommended. In this report, a case of nasopharyngeal myiasis in a 75-year-old patient hospitalized in the intensive care unit is presented. Nine larvae were detected in the patient's nose. Larvae were removed from the area and were cleaned with iodine solution for three days. As a result of macroscopic and microscopic examination, the larvae were identified as the third stage of sp. in order to prevent myiasis infestations, personnel working in places where the patient is unconscious, such as intensive care units, should daily check the patient's body cavities such as nose, mouth and ear cavities, and perform their care and cleaning.

INTRODUCTION
The term myiasis is applied to the injurious action that larvae of certain Diptera cause in vertebrate animals by growing in living or dead tissue. Because of its great destructive potential, appropriate and preventive treatment is necessary. Oral myiasis is a rare pathology in humans and is associated with poor oral hygiene, alcoholism, senility, suppurating lesion, severe halitosis, and other conditions.
METHOD
We have presented a case of oral myiasis in a mentally challenged patient.
RESULTS
Reviewing the literature revealed that most of the cases involved the anterior part of the oral cavity of male patients living in developing or underdeveloped countries and also that predisposing factors invariably accompanied infestation.

Review
"Myiasis-causing flies" is a generic term that includes species from numerous dipteran families, mainly Calliphoridae and Oestridae, of which blowflies, screwworm flies and botflies are among the most important. This group of flies is characterized by the ability of their larvae to develop in animal flesh. When the host is a live vertebrate, such parasitism by dipterous larvae is known as primary myiasis. Myiasis-causing flies can be classified as saprophagous (free-living species), facultative or obligate parasites. Many of these flies are of great medical and veterinary importance in Brazil because of their role as key livestock insect-pests and vectors of pathogens, in addition to being considered important legal evidence in forensic entomology. The characterization of myiasis-causing flies using molecular markers to study mtDNA (by RFLP) and nuclear DNA (by RAPD and microsatellite) has been used to identify the evolutionary mechanisms responsible for specific patterns of genetic variability. These approaches have been successfully used to analyze the population structures of the New World screwworm fly Cochliomyia hominivorax and the botfly Dermatobia hominis. In this review, various aspects of the organization, evolution and potential applications of the mitochondrial genome of myiasis-causing flies in Brazil, and the analysis of nuclear markers in genetic studies of populations, are discussed.

Review
A 29-year-old man with a furuncle-like lesion brought in a maggot on the next day after his first visit to our clinic. He said it moved out from the eruption spontaneously. He had previously visited Parana and Sao Paulo in Brazil before he noticed the symptom. The maggot was confirmed to be a third instar larva of Dermatobia hominis. Japanese cases of cutaneous myiasis are reviewed.
