Protothecosis is a severe, emerging opportunistic infection caused by the saprophytic, achlorophyllous microalgae of the genus Prototheca. Though uncommon, human and animal cases are increasing worldwide, making awareness of this fungal-like pathogen important in both human and veterinary medicine. We report a fatal case of disseminated protothecosis caused by P.

Endotypes are characterized by the immunological, inflammatory, metabolic, and remodelling pathways that explain the mechanisms underlying the clinical presentation (phenotype) of a disease. Recessive dystrophic epidermolysis bullosa (RDEB) is a severe blistering disease caused by COL7A1 pathogenic variants. Although underscored by animal studies, the endotypes of human RDEB are poorly understood.

Background: Leishmaniasis (LI) is a vector-borne illness caused by a protozoan of the genus Leishmania. Data on the features of LI in patients with inflammatory bowel disease (IBD) are scarce.
Aim: To describe the characteristics of patients with IBD who present with leishmaniasis, infection outcomes and the risk factors associated with developing visceral leishmaniasis (VL).

Phaeohyphomycosis is a fungal infection caused by dematiaceous fungi that presents as a superficial, cutaneous, subcutaneous, or systemic infection. Subcutaneous phaeohyphomycosis is the most common manifestation and presents as a subcutaneous nodule or cystic lesions and abscesses. It usually results from traumatic implantation of the saprophytic fungus from soil and vegetative matter; therefore, the commonest sites of infection are the extremities.

Alterations in the lipid layer and intercellular corneocyte connections can lead to increased allergen penetration through the skin surface. A normal cutaneous microbiome keeps the opportunistic pathogen Staphylococcus pseudintermedius levels low, but allergic inflammation leads to decreased diversity and increase in S pseudintermedius. Keratinocytes sound the initial allergen alarm via cytokine signaling and promote T-helper 2 (Th-2) inflammation.
