“…Over the years many studies recorded the presence of Ornithonyssus sylviarum (Canestrini & Fanzago, 1877), a species similar to O. bursa, parasitizing several birds in Brazil (FACCINI & MASSARD, 1974;PEREIRA et al, 1977;FACCINI, 1987;FACCINI et al, 1991;SERAFINI et al, 2003;SOARES et al, 2008). To have a clear separation between these two species, the main differences are: posterior margin of the dorsal shield of O. sylviarum much narrower than in O. bursa.…”

Ornithonyssus bursa, known as the “tropical fowl mite”, is a hematophagous mite of domestic and wild birds, occasionally biting humans. Infestation on humans occurs mainly when the abandoned nests are close to homes, or by manipulation of infested birds by humans. In Brazil, this species occurs in the south and southeast of the country. In the present study we are reporting bites on humans, new localities records, host associations, and molecular information of O. bursa.

“…Resultados contrários aos deste estudo foram observados por Soares et al (2008) que concluíram que o uso do Azadirachta indica na alimentação de poedeiras representa mais uma alternativa no controle de ectoparasitas e vem ao encontro das necessidades de uma avicultura moderna, na busca por alimentos seguros mais saudáveis. Vale ressaltar que a ciência homeopática difere em suas respostas a campo, em que uma menor quantidade utilizada de tal substancia, gera o melhor resultado, o que dificulta comparações com trabalhos que não são com homeopatia.…”

Homeopathic products are one of the main alternatives to allopathic products, having several commercial products for veterinary use available on the market for different purposes. Therefore, the objective was to evaluate the zootechnical performance, egg quality and ectoparasites (lice) count in laying hens with advanced ages. The experiment was carried out at the Federal Institute of Triângulo Mineiro - Uberaba campus, using 90 birds of the commercial Delkalb® lineage, aged 89 to 93 weeks, distributed in a completely randomized design, divided into three treatments with five replications containing 6 birds per repetition totaling 30 birds per treatment. The treatments used consisted of: treatment 1 - without using the homeopathic product; treatment 2 - 1.0 g/bird/day of the homeopathic additive, treatment 3 - 1.5 g/bird/day of the homeopathic additive. No statistical difference was observed regarding the zootechnical performance and egg quality, however the percentage of laying of the birds were in expected values for the age of the birds, as for the egg quality, it can be observed that the Haugh unit was well below the values found in literature. The ectoparasite counts were not statistically influenced using the homeopathic product, this effect can be explained due to the high rate of lice infestation that affected the birds. It was concluded that the homeopathic product used was not efficient in controlling the infestation of ectoparasites (lice) present in birds, however it did not have any adverse effects on zootechnical performance or egg quality.

“…Likewise, D. gallinae is highly prevalent in Portugal, with over 90% of layer farms affected (11). O. sylviarum occurs throughout the temperate regions of the world, but is primarily important in North America, where it is regarded as the most common and damaging ectoparasite of poultry (12), Brazil (13,14), China (15), and Australia (16). In Europe, O. sylviarum was the most frequent mite in nests of wild birds in Slovakia, Italy and Austria (17)(18)(19).…”

Case Report: Human Dermatitis Linked to Ornithonyssus bursa (Dermanyssoidea: Macronyssidae) Infestation in Portugal

Ornithonyssus bursa (Berlese, 1888), also known as the tropical fowl mite, is a blood-feeding ectoparasite of domestic and wild birds. It is considered a serious pest to poultry in warm and tropical climates and has been reported to attack humans, causing gamasoidosis. Avian-mite dermatitis may be difficult to recognize and misdiagnosed as bites from other arthropods. The present report describes two cases of human dermatitis linked to O. bursa infestation. Both cases occurred in an apartment in a residential area in Oeiras, Portugal, where two members of the same family presented with pruritic erythematous skin eruptions disseminated over their body over a period of 4 months. The lesions were located mostly in the pelvic, gluteal, coccygeal, and perineal regions, and also on the neck, wrists and torso. On inspecting the mattresses and the covers of the bedrooms, three mites ~1 mm long by 0.5 mm wide were found. The three specimens were identified as O. bursa. Investigations tracing back the source of infestation, revealed that the mites were carried over from chickens raised 45 km away (Sesimbra, Setúbal) that, after being slaughtered for consumption, had been transported by car to the apartment in Oeiras. The chickens were farmed in an open backyard henhouse that allowed free access to several species of wild birds, including pigeons (Columba livia), turtle doves (Streptopelia decaocto), and sparrows (Passer domesticus). Recent reports suggest that O. bursa may be established in Mediterranean countries, increasing the risk of gamasoidosis. This is the first record linking O. bursa infestation of chickens with human dermatitis in continental Portugal. More research is needed to assess the extent of poultry infestation and evaluate the possible implications for the poultry industry, as well as for human health in Portugal.
