    Neglected endemic mycoses.
    Lancet Infect Dis 2017 Jul 31. Epub 2017 Jul 31.
    Santa Casa de Misericórdia de Porto Alegre, Porto Alegre, Brazil; Universidade Federal de Ciências da Saúde de Porto Alegre, Porto Alegre, Brazil.
    Fungi often infect mammalian hosts via the respiratory route, but traumatic transcutaneous implantation is also an important source of infections. Environmental exposure to spores of pathogenic fungi can result in subclinical and unrecognised syndromes, allergic manifestations, and even overt disease. After traumatic cutaneous inoculation, several fungi can cause neglected mycoses such as sporotrichosis, chromoblastomycosis, mycetoma, entomophthoramycosis, and lacaziosis. Read More

    Fungi that Infect Humans.
    Microbiol Spectr 2017 Jun;5(3)
    Division of Infectious Diseases, Duke University Medical Center, Durham, NC 27710.
    Fungi must meet four criteria to infect humans: growth at human body temperatures, circumvention or penetration of surface barriers, lysis and absorption of tissue, and resistance to immune defenses, including elevated body temperatures. Morphogenesis between small round, detachable cells and long, connected cells is the mechanism by which fungi solve problems of locomotion around or through host barriers. Secretion of lytic enzymes, and uptake systems for the released nutrients, are necessary if a fungus is to nutritionally utilize human tissue. Read More

    Non-dermatophyte Dermatoses Mimicking Dermatophytoses in Animals.
    Mycopathologia 2017 Feb 16;182(1-2):113-126. Epub 2016 Nov 16.
    UP Interactions Cellules Environnement, VetAgro Sup, Univ Lyon, 69280, Marcy l'Etoile, France.
    Dermatophytoses in animals are fungal diseases of the skin caused by dermatophyte fungi of the genus Microsporum or Trichophyton. Because the infection is generally follicular, the most common clinical sign is one or many circular areas of alopecia with variable erythema, scaling and crusting, and the primary differential diagnoses are follicular infections, such as bacterial folliculitis and demodicosis. Although dermatophyte folliculitis or ringworm is the most commonly observed lesion of dermatophytoses in animals, other presentations may be observed according to the host species and the dermatophyte involved: dermatophyte folliculitis or ringworm, scaling and crusting in dermatophytosis due to Microsporum persicolor, nodule in case of kerion or mycetoma, matted hairs, seborrheic dermatosis or miliary dermatitis in cats, generalized exfoliative dermatoses in dogs, cats and horses, superficial non-follicular pustules, papules and macules in the Devon Rex cat, pruritic dermatophytoses in dogs, cats and horses, and onychomycosis in dogs, cats and horses.
