Wound myiasis of sheep in Hungary
Veterinary Parasitology, 1997
In Hungary, 4388 sheep in six flocks were surveyed in June-August of 1992-1995 to gather basic data on wound myiasis, its incidence, the predominant fly species involved and the clinical manifestations of infestation. The pathogenesis and economic significance of wound myiasis, as well as the interrelation of breed and sex with infestation levels, were evaluated.
Atypical Mycosis in Psittacine Birds: A Retrospective Study
Frontiers in Veterinary Science
A retrospective study was conducted on parrots submitted from necropsy to the Department of Veterinary Pathology, School of Biosciences and Veterinary, University of Camerino, Italy, from 2007 to 2018. From a total of 2,153 parrots examined at post-mortem, four cases were diagnosed with atypical mycosis and were considered for determination of the fungus species by PCR. A Fischer's lovebird (Agapornis fischeri), Peach-faced lovebirds (Agapornis roseicollis), and two Blue and Gold Macaws (Ara ararauna) from four different aviaries died after some days of lethargy and ruffled feathers. Records of gross necropsy and histopathological exams (H&E, PAS, and Grocott stain) were described and biomolecular analyses were carried out. No specific gross lesions were appreciated at necropsy, while histopathology evidenced a systemic mycosis in several organs, particularly in the lungs. In affected organs, broad and non-septate hyphae, suggestive of mycoses, were observed. Molecularly, Mucor ...

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, Anser anser domesticus L. (Anseriformes: Anatidae), in June 2020 in a rural area of the region Calabria (Southern Italy). The myiasis was caused by Lucilia sericata (Meigen) (Diptera: Calliphoridae). In Italy, this was the first case of myiasis by L. sericata 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 L. sericata in birds reported worldwide, useful for monitoring and management of dipteran species of medical and veterinary interest.

The first case of traumatic myiasis caused by Musca domestica in a dog in Konya, Turkey
TURKISH JOURNAL OF VETERINARY AND ANIMAL SCIENCES, 2018
Introduction Myiasis is a parasitic infestation of a live mammal with dipterous larvae which, at least for a certain period, feed on the host's dead or living tissue, liquid substances, or ingested food (1-3). In myiasis cases, eggs or larvae of some flies in the order Diptera are deposited in wounds or nasal, oral, aural, anal, or gastrointestinal cavities of vertebrate hosts. The feeding activity of the larvae found in wounds may cause severe tissue damage, resulting in reproductive problems, blindness, lameness, and even death (4). Myiasis can be classified as obligatory, facultative, or accidental based on the type of host-parasite relationship, as well as dermal, cutaneous, gastric, nasal, auricular, anal, intestinal, etc., depending on the anatomical site where the larvae are located (3,5). There have been many studies conducted on myiasis caused by several Dipteran species throughout the world (1,2,4,6-9), including Turkey (10-14). Some flies belonging to the families Sarcophagidae, Calliphoridae and, rarely, Muscidae can cause traumatic myiasis, as well as nasal, genital, oral, and ocular infestation. Wohlfahrtia magnifica (Schiner 1862) and Lucilia sericata (Meigen 1826) in the families of Sarcophagidae and Calliphoridae, respectively, are the predominant agents of traumatic myiasis in humans and animals in Turkey (3). Musca domestica (Linnaeus 1758), commonly known as the housefly, lives in houses and stables, typically in large numbers. These insects can cause irritation and 2.

Outbreaks of Mycoplasmosis and Histomoniasis in a Southern Brazilian Flock of Ornamental Birds
Acta Scientiae Veterinariae, 2017
Background: Infectious diseases have expanded their host and geographic ranges, increasing impacts on both human and animal health. Mycoplasma gallisepticum usually causes avian chronic respiratory conditions and Histomonas meleagridis infects the cecum and the liver of poultry. Although these diseases have been reported in several bird species, information associated with their prevalence and impact in local flocks of ornamental birds is scarce. This communication describes severe outbreaks of mycoplasmosis and histomoniasis that affected a southern Brazilian commercial flock of ornamental birds. Case: The outbreaks occurred in an ornamental bird flock that contained 2,340 birds from 39 different species, distributed mostly in the orders Galliformes, Anseriformes, and Psittaciformes. Mycoplasma gallisepticum affected 12 chukar partridges, 12 Indian peacocks, 19 ornamental chickens and 46 individuals of 4 species of pheasant. The disease cases were distributed between April and July 2015. A total of 36 birds died due to the disease' complications and most surviving birds suffered from severe ocular sequels, which determined their subsequent culling, despite attempts of different treatment protocols. The main signs included coughing, sneezing, infraorbital swelling, wasting, and death which were mostly associated with caseous sinusitis. Affected birds had positive samples when stained with anti-Mycoplasma gallisepticum immunohistochemistry and tested by Mycoplasma gallisepticum-Polymerase Chain Reaction. The application of 2 doses of a Mycoplasma gallisepticum vaccine in early 2016 to all the Galliformes in the flock reduced the annual prevalence to 4 clinical cases. Histomoniasis affected and killed 19 out of 27 chukar partridges that were being kept with ring-necked pheasants in the same enclosure. The disease occurred between September and December 2016 and a high prevalence of Heterakis gallinarum was detected in the flock. The main findings included apathy and death linked to hepatic and cecal necrosis. Admixed in the necrotic areas, there were numerous round to oval, eosinophilic, protozoal trophozoites of 15-20 µm in diameter, occasionally containing a 3-5 µm centrally located basophilic nucleus (histomonads) surrounded by a clear halo. Anthelmintic dosing, exchanging and liming the bedding material of the enclosures, and keeping the remaining partridges in an aerial aviary with a wire mesh floor prevented additional cases of histomoniasis. Discussion: In Brazil, as in other countries, the sanitary management practices applied in commercial chicken production reached high levels of technification. However, this is not the case in ornamental bird breeding systems, which may still suffer the impacts of diseases that are practically extinct in industrial chicken flocks. For both diseases, diagnosis was based on typical clinical signs and detection of the pathogens in association with characteristic pathological findings. The occurrence of mycoplasmosis and histomoniasis was associated with improper management practices at the farm; the main risk factors observed were a high turnover of birds, the absence of quarantine, the absence of basic health care, overcrowding and poor hygiene. The prevention of further cases of both diseases was mostly established with the application of basic sanitary measures, including vaccination and anthelmintic dosing, for mycoplasmosis and histomoniasis respectively. This report alerts bird keepers and avian veterinarians of the importance of establishing proper sanitary management in local ornamental bird flocks. Because some of the ornamental bird species that have been commercially propagated worldwide may be included in the list of threatened species, the findings described here also show that simple health care may promote the fight against extinctions.
Traumatic myiasis in free-ranging eland, reported from Kenya
Parasites & Vectors, 2013
Background: For centuries, immature stages of Dipterans have infested humans and animals, resulting in a pathological condition referred to as myiasis. Myiases are globally distributed but they remain neglected diseases in spite of the great medical and veterinary importance. Moreover, there is a paucity of information on the clinical-pathology and/or epidemiology of the infestation, especially in African free ranging wildlife. Findings: In the present study we report for the first time an outbreak of traumatic cutaneous myiasis (caused by Old World screwworm, Chrysomyia bezziana and blowfly, Lucilia sp.) in free-ranging common elands (Taurotragus oryx). The infestation affected both animal sexes and different age classes, and had a negative impact on individual fitness as well as the overall health. Severely affected individuals were euthanized, while others were clinically treated, and apparently recovered. Conclusions: This study indicates that myiasis-causing flies still exist in Kenya and are able to cause severe outbreaks of clinical cutaneous myiasis in wild animals. The status of these parasites in Kenya, which are of zoonotic potential, are either unknown or neglected.
Participation of insects in spreading parasitic invasion in geese reared in a traditional way
1998
The studies were conducted in a private fann near Olsztyn, from May to October 1996. Recent goose excrements were collected in May and October and examined for developmental stages of parasites, using the decantation and Fulleborn tlotation methods. Once a month, from May to October, 5 soil sampIes (of the same volume) and the same number of turf sampIes were collected from pasture lands. Turf sampIes were examined for the oocysts, eggs and larvae of parasites: Insects were obtained from soil sampIes and examined for the degree of their infestation with different forms of bird parasites. Coccidias (Eimeria sp.) and nematodes (Amnidostomum anseris, Ascaridia gaili and Trichostrongylus sp.) were found in the geese. A few developmental fonns of bird parasites were found in the turf and on insects. Oocysts of Eimeria sp. (14), eggs of Trichostrongylus sp. (30) and eggs of nematodes from the group ,Jleterakis-Ascaridia" (6) were found in the turf, while 2 Eimeria sp. oocysts and 4 eggs of Trichostrongylus sp. were found on the insects. The results show that the role of insects in spreading parasitic invasions of birds was smaller in the examined biotope than it had been previsted.

Myiasis represents an infestation of animals and humans caused by the maggots of certain fly species of Diptera order, Insecta class, which feed on the hosts' living or dead tissues or body fluids. In sheep, myiasis is a major animal welfare issue developing serious pain, suffering and in untreated cases may result in tissue injuries, reproduction and productivity losses and even death. There are two most important fly species which cause traumatic cutaneous myiasis of sheep in Europe: Wohlfahrtia magnifica (Sarcophagidae) implicated in etiology of wound myiasis in southern and eastern Europe and Lucilia sericata (Calliphoridae), implicated in etiology of sheep strike, mainly in the middle latitudes of Europe continent. A few farmers from Timiş, Arad and Caraş-Severin counties were been asked to response to a questionnaire on the prevalence of traumatic myiasis which evolved in their sheep flock in April-September period of year 2012. From a total number of 2206 sheep taken into...
