“…However, this tool is helpful only when the mites are present on the patient's skin, although this must be considered a rather rare circumstance (Navarrete-Dechent & Uribe, 2018). Dermoscopy evaluation of D. gallinae-induced dermatitis also reveals dilated vessels on an erythematous background in correspondence to the macules and papules, and reflectance confocal microscopy demonstrates the presence of intraepidermal vesicles (Cinotti et al, 2015).…”

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.

“…In addition, PRMs may play a role as vectors in the transmission of avian pathogens [23]. Furthermore, PRM infestations often cause allergic reactions in humans, including both poultry workers and urban residents [1,7,13,16], and a recent study reported the detection of zoonotic agents in PRMs [18]. Thus, PRMs are harmful pests to the poultry industry and a threat to human health.…”

Characterisation of a cysteine protease from poultry red mites and its potential use as a vaccine for chickens

et al. 2021

Poultry red mites (PRMs, Dermanyssus gallinae) are ectoparasites that negatively affect farmed chickens, leading to serious economic losses worldwide. Acaricides have been used to control PRMs in poultry houses. However, some PRMs have developed resistance to acaricides, and therefore different approaches are required to manage the problems caused by PRMs. Vaccination of chickens is one of the methods being considered to reduce the number of PRMs in poultry houses. In a previous study, a cysteine protease, Deg-CPR-1, was identified as a candidate vaccine against PRMs distributed in Europe. In this study, we investigated the characteristics of Deg-CPR-1. A phylogenetic analysis revealed that Deg-CPR-1 is closely related to the digestive cysteine proteases of other mite species, and it was classified into a cluster different from that of chicken cathepsins. Deg-CPR-1 of PRMs in Japan has an amino acid substitution compared with that of PRMs in Europe, but it showed efficacy as a vaccine, consistent with previous findings. Deg-CPR-1 exhibited cathepsin L-like enzyme activity. In addition, the Deg-CPR-1 mRNA was expressed in the midgut and in all stages of PRMs that feed on blood. These results imply that Deg-CPR-1 in the midgut may have important functions in physiological processes, and the inhibition of its expression may contribute to the efficacy of a Deg-CPR-1-based vaccine. Further research is required to fully understand the mechanisms of vaccine efficacy.

“…Parasite bite reactions are often non-specific and new noninvasive imaging devices can help in the diagnosis by showing blood extravasation and microscopic signs of inflammation. [1][2][3] Moreover, they help the exact identification of the hematophagus parasite 1-3 as in our case where a bedbug infestation was diagnosed. Dermoscopy can be used as an initial screening in order to detect the parasites and RCM and HD-OCT can be used to highlight their anatomical features.…”
