- Human ectoparasitosis by mites of the genus Pyemotes Amerling 1861 (Acarina: Pyemotidae). [Journal Article]Ital J Dermatol Venerol. 2023 Jan 04 [Online ahead of print]IJ
- The mites of the family Pyemotidae Berlese (1897) are a large family of ectoparasitoids arthropods, known as pathogen for humans since the 18th century and responsible for the so-called "straw itch" or "grain itch" in granary and dock workers. The identified species of the genus Pyemotes are divided into two groups: the scolyti group (P. scolyti, P. parviscolyti and P. dimorphus) and the ventrico…

- Role of Staphylococcus agnetis and Staphylococcus hyicus in the Pathogenesis of Buffalo Fly Skin Lesions in Cattle. [Journal Article]
- Buffalo flies (Haematobia irritans exigua) are hematophagous ectoparasites of cattle causing production and welfare impacts in northern Australian herds. Skin lesions associated with buffalo fly infestation and Stephanofilaria nematode infection are manifested as focal dermatitis or ulcerated areas, most commonly on the medial canthus of the eye, along the lateral and ventral neck, and on the abd…

- De novo transcriptome sequencing and functional annotation of Demodex canis. [Journal Article]
- Demodex canis is an important parasitic mite causing skin lesions in dogs. However, molecular studies on this species are limited because of the lack of transcriptomic data. To obtain functional genes of D. canis, mites were collected and RNA was extracted for transcriptome sequencing and functional annotation. Coding sequences (CDSs) of important functional genes were screened and identified usi…

- Unraveling the distinctive venomous features of the saturniid Hylesia sp.: An integrative approach of a public health concern in Argentina. [Journal Article]
- The saturniid genus Hylesia is well known for the cutaneous lepidopterism induced by airborne setae on contact with the skin. Although several cases of such dermatitis have been reported in Argentina, no information about their venoms and toxicological implications on human health is available yet. Thus, we conducted a morphological analysis of the setae/spines and a toxinological characterizatio…

- Lutzomyia longipalpis is the natural vector of Leishmania (Leishmania) infantum, but it is also permissive for several Leishmania species that are related to cutaneous leishmaniasis (CL). Maranhao State (Northeast of Brazil) is endemic for CL and has the highest number of cases of diffuse cutaneous leishmaniasis (DCL) in the country. It is a rare disease associated with a defective immune respons…

- Exogenous acral pigmentation secondary to beetle exposure. [Case Reports]Pediatr Dermatol. 2021 Nov; 38(6):1594-1596.PD
- We present a 5-year-old girl who accidentally crushed an insect of the coleoptera family walking barefoot and secondarily developed an exogenous acral pigmentation. The lesions resolved spontaneously within a few weeks. Proper identification of the insect and a detailed physical examination were key to avoiding unnecessary invasive diagnostic tests.

- CONCLUSIONS: To the authors' knowledge, this is the first reported case of sarcoptic mange in wild boar in Spain and the first documented case of S. scabiei cross-transmission from a wild ruminant host to a wild boar. The wild boar presented an ordinary scabies type reaction, which is typical of the self-limiting infestations reported in other cases of interspecific transmission.

- Topical application of celastrol alleviates atopic dermatitis symptoms mediated through the regulation of thymic stromal lymphopoietin and group 2 innate lymphoid cells. [Journal Article]
- Atopic dermatitis is a chronic inflammatory skin disease, of which incidence is closely related to exposure to environmental pollutants and allergens. Thymic stromal lymphopoietin (TSLP) plays an important role in the early stages of atopic dermatitis development by inducing Th2 immune responses. In addition, TSLP regulates activation of group 2 innate lymphoid cells (ILC2), promoting the pathoge…

- Cera Flava (CF), a natural extract obtained from beehives, is widely used in dermatological products owing to its wound healing, wrinkle reduction, UV-protective, and skin cell turnover stimulation effects. However, its effect on AD-like skin lesions is unknown. In this study, we used a mouse model of AD to evaluate the effects of CP at the molecular and phenotypic levels. Topical house dust mite…

- First report of Ericotrombidium ibericense in domestic dogs. [Journal Article]
- CONCLUSIONS: Most of the trombiculids recorded in European clinical practice are generally identified as Neotrombicula autumnalis by default, since, in most cases, mites are not examined morphologically. This is the first record of E. ibericense in domestic dogs. More studies are needed to evaluate the distribution of these mites in Portugal. Veterinary clinicians must be aware of this parasitosis, as trombiculids can cause exuberant clinical signs, but are often misdiagnosed.
