“…Though a possible carryover of D. gallinae into the apartment cannot be completely ruled out, as one specimen was retrieved in the traps placed later in the henhouse, the finding of only O. bursa in the bed linens, enabling prolonged skin contact with one of the afflicted individuals, strongly suggests this mite as the cause of the observed dermatitis. Based on previous records in wild and synatrophic birds and human infestation in other Mediterranean countries, the present findings suggest that O. bursa can be prevalent in the Mediterranean basin but it could be overlooked or misdiagnosed (38,39,42). The typical Mediterranean climate is characterized by warm to hot, dry summers and mild to cool, wet winters; these conditions could be suitable for this tropical mite to develop.…”

“…O. sylviarum and D. gallinae are the mites most frequently implicated in gamasoidosis, the latter with over 170 outbreaks registered in Europe (4,37). Although comparatively less common, human infestations by O. bursa have been reported before in urban residential areas of India (38) and Brazil (35,(39)(40)(41). In both cases the source of mites was traced to abandoned bird nests.…”

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.

“…The following characteristics were described. Dorsal plate complete with short setae and with gradual distal narrowing, posterior margin of dorsal shield with four pairs of posterior setae, Z4 present and short (Figure 1A-C); sternal plate with three sternal setae inside the plate (Figure 2C); chelicerae not enlarged distally (Figure 2B); epigynal plate with tapered distal end (Figure 2D); anal plate longer than wide (Figure 2A) (Strandtmann & Wharton, 1958;Denmark & Cromroy, 2003;Radovsky, 2010;Lareschi et al, 2017;Bassini-Silva et al, 2019).…”

“…This mite belongs to the order Mesostigmata and parasitizes passerines and domestic birds (Sreenivasa Murthy & Panda, 2016). It is found in warmer areas of the world including North, Central and South America, in Argentina, Brazil and Colombia (Aramburú et al, 2002;Mascarenhas et al, 2009;Sreenivasa Murthy & Panda, 2016;Bassini-Silva et al, 2019;Mesquita-Sousa et al, 2020). It was recently described as an invasive parasite in Italy (Castelli et al, 2015) and Spain (Mori et al, 2019).…”

Myiopsitta monachus is an invasive psittacine with wide distribution due to the pet trade. Its large communal nests and synanthropic nature contribute to its successful colonization of cities, from where it seems to be expanding in range and numbers. This is relevant with regard to pathogens that invasive species may harbor, especially when host populations thrive. We aimed to identify an abundant mite found in invasive monk parakeet chicks that had been collected in Santiago during 2017 and 2018. Through morphological and molecular identification of the 18S ribosomal RNA gene, we confirmed the presence of Ornithonyssus bursa. This was the first report of this mite in Chile. This mite is common in native and invasive monk parakeet populations and may affect other birds, including domestic fowl. Further, this mite bites people and can be a potential vector of pathogens such as bacteria or viruses. We conclude that this parasite was likely introduced with the parakeet and discuss possible ecological, health and economic consequences of this new potential pest.

“…gallinae is relatively small at the adult stage (0.5-1 mm long), with long legs and a greyish-white body that becomes reddish-brown when engorged ( Figure 4). However, since cases of dermatitis caused by the avian mites Ornithonyssus bursa (Castelli et al, 2015;Mentz et al, 2015;Bassini-Silva et al, 2019) and Ornithonyssus sylviarum (Orton et al, 2000;Cafiero et al, 2018), or by the rodent mite Ornithonyssus bacoti (Beck & Fölster-Holst, 2009;Cafiero et al, 2016) have been recorded in humans even recently, there may be some confusion over identification of the mite responsible.…”

Dermanysuss gallinaeattacks humans. Mind the gap!

Dermanyssus gallinae is a haematophagous ectoparasite primarily known as a pest of domestic and wild birds. It occasionally feeds on a range of mammals, and, more importantly, is of growing concern in human medicine. This review highlights mite attacks on people working with poultry, and updates the increasing incidence of dermanyssosis in urban environments in Europe. Although several cases of dermanyssosis have been documented, there are a number of reasons why diagnosis of D. gallinae infestations in humans is likely to be underestimated. Firstly, medical specialists are not well aware of D. gallinae infestations in humans. There is also a lack of collaboration with specialists from other disciplines. The problem is compounded by misdiagnoses and by the lack of diagnostic tools. We review the literature on human dermanyssosis cases in Europe, and also provide information on the epidemiology, clinical, histo-pathological and immunological aspects of dermanyssosis. We stress the need for improved recognition of this challenging infestation in humans, and provide straightforward recommendations for health practitioners, starting with collection of the correct anamnestic information and including appropriate management methods for case recognition and resolution. Finally, we indicate the most urgent areas to be addressed by future research. RESEARCH HIGHLIGHTS. Dermanyssus gallinae is of growing concern in human medicine.. Most physicians are not well aware of dermanyssosis in humans.. Bio-epidemiological and clinical aspects of this ectoparasitosis are highlighted.. Practical key actions for diagnosis and correct management of infestation in humans are provided.
