Rhinosporidium seeberi is a eukaryotic pathogen responsible for rhinosporidiosis, a disease which affects humans, horses, dogs, and to a lesser extent cattle, cats, foxes, and birds. [2] It is most commonly found in tropical areas, especially India and Sri Lanka. [2] [3]
Dr. MacMillan says: "These dogs are more prone to secondary skin infections (pyoderma or yeast overgrowth) which may also require treatment, such as medicated shampoos and antibiotics ...
Hence, animals, cats and dogs are believed to be the population hosts of this fungus, while humans are occasional hosts, in which the fungus can induce secondary infections. [4] Microsporum canis has been identified as a causal agent of a ringworm infection in pets, tinea capitis and tinea corporis in humans, children in particular. [2] [3] [5 ...
The yeast form of S. schenckii is effectively phagocytosed by cells of the innate immune system [34] and are recognized based on the sugars displayed on their surface [35] or lipids in the yeast cell membrane. [34] Although they are taken up, they are not efficiently killed.
Saccharomycotina is a subdivision (subphylum) of the division (phylum) Ascomycota in the kingdom Fungi. [2] [3] It comprises most of the ascomycete yeasts.The members of Saccharomycotina reproduce by budding and they do not produce ascocarps (fruiting bodies).
Cryptococcus neoformans is an encapsulated basidiomycetous yeast [1] belonging to the class Tremellomycetes and an obligate aerobe [2] that can live in both plants and animals. Its teleomorph is a filamentous fungus, formerly referred to Filobasidiella neoformans. In its yeast state, it is often found in bird excrement.
It is capable of causing disease in non-immunocompromised people. In its yeast state it has been isolated from eucalyptus trees in Australia. The taxonomy of C. gattii has been reviewed; it has now been divided into five species: C. gattii sensu stricto, C. bacillisporus, 'C. deuterogattii, C. tetragattii, and C. decagattii. [10] [2]
Rhodotorula mucilaginosa cells, Methylene blue stain, magnification 400x. Rhodotorula is a genus of fungi in the class Microbotryomycetes.Most species are known in their yeast states which produce orange to red colonies when grown on Sabouraud's dextrose agar (SDA).
