A printable chart to make a spore print and start identification. The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse.
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 ...
Malassezia pachydermatis is a zoophilic yeast in the division Basidiomycota.It was first isolated in 1925 by Fred Weidman, and it was named pachydermatis (Greek for 'thick-skin') after the original sample taken from an Indian rhinoceros (Rhinocerosus unicornis) with severe exfoliative dermatitis. [2]
The yeast-like cells of Malassezia, measuring between 1.5–4.5 μm by 3–7 μm, are characterised as phialides featuring tiny collarettes (a small, collar-like flange or lip at the mouth of a phialide from which spores or conidia are produced and released). These collarettes are challenging to identify using standard light microscopes.
Sporothrix infection can also be transmitted by cat bites or scratches. This mode of transmission has been responsible for epidemics of sporotrichosis. [ 12 ] Immunocompromised individuals are at increased risk of infection and such patients often exhibit more severe forms of disease.
Cats with sporotrichosis are unique in that the exudate from their lesions may contain numerous infectious organisms. This makes cytological evaluation of exudate a valuable diagnostic tool in this species. Exudate is pyogranulomatous, and phagocytic cells may be packed with yeast forms. These yeast cells are variable in size; many are cigar ...
Toxocariasis is an illness of humans caused by the dog roundworm (Toxocara canis) and, less frequently, the cat roundworm (Toxocara cati). [1] These are the most common intestinal roundworms of dogs, coyotes, wolves and foxes and domestic cats, respectively. [2] Humans are among the many "accidental" or paratenic hosts of these roundworms. [3]
The fungus also infects animals, such as dogs, koalas, and dolphins. [5] In 2007, the fungus appeared for the first time in the United States, in Whatcom County, Washington [6] and in April 2010 had spread to Oregon. [7] The most recently identified strain, designated VGIIc, is particularly virulent, having proved fatal in 19 of 218 known cases ...
