First report of Neotrombicula inopinata infestation in domestic cats from Portugal

Ramilo, Carla Monteiro, Marrion Carreira, Isabel Pereira da Fonseca, Luís CardosoAbstractTrombiculids parasitize a wide variety of terrestrial vertebrates, including domestic animals, throughout the world. They are parasites only during their larval stages, causing several dermatological lesions on their hosts, such as acute dermatitis, erythema, excoriation, erosion, papules, crusts and alopecia on the ear margins, face, interdigital spaces and abdomen. Neotrombicula is one of the several genera in Trombiculidae family, which cause trombiculosis. The most common species implicated in clinical cases is Neotrombicula autumnalis. However, several reports have shown that Neotrombicula inopinata (Oudemans, 1909) can also play a role in trombiculosis. Here, we describe the first case of N. inopinata infestation in domestic cats from mainland Portugal. Since nucleic acids of Anaplasma phagocytophilum and Borrelia burgdorferi have been found in Neotrombicula autumnalis and Rickettsia spp. in Neotrombicula inopinata, a correct taxonomical identification is essential to understand the role of these mite species as possible vectors of pathogens.

These parasites significantly affect the economy and cause public health burdens globally. Protozoan parasites share many cellular features and pathways with their respective host cells. This includes autophagy, a process responsible for self-degradation of the cell's components. There is co...

In this study the consumption of anticancer drugs in the Lisbon region (Portugal), Belgium and Haryana state (India) were used to estimate the concentrations that can be expected in surface waters.Moreover, one important aspect is to define the major entry route of anticancer drugs in the aquatic environment: is it hospital or household effluents? The results disclosed in this study showed that in Belgium and Lisbon, 94% of the total amount of anticancer drugs were delivered to outpatients, indicating that household effluents are the primary input source of these drugs and thus, upgrading the treatment in the domestic wast...

We aimed to develop an in vitro culture system that synthesized epidermal CER classes to better understand the synthesis of CER classes in canine SC.. Canine keratinocyte cells (MSCEK) at appropriate confluency were incubated with high Ca2+ (1.8 mM CaCl2) supplemented serum-free medium. Eight days post Ca2+ application, the surface of cultured MSCEK was broad...

BragaAbstractIn Portugal, the pinewood nematode (PWN), Bursaphelenchus xylophilus, has been affecting Pinus pinaster, leading to economic and ecological losses, while P. pinea is a less susceptible species. The main goal of this study was to assess volatile composition of PWN-infected P. pinaster, and both non-infected P. pinaster and P. pinea branches, by using supercritical carbon dioxide extraction compared with solid-phase microextraction (SPME). Volatil...

Forkhead box protein P3 (FOXP3), a member of the forkhead–winged-helix family, is the pivotal transcriptional factor of Treg cells. The expression, post-translational modifications, and protein complex of FOXP3 present a great impact on the functional stability and immune plasticity of Treg cells in vivo. In ...
