Cutaneous sporotrichosis in a stray cat from Thailand

Purpose To report a case of conjunctival plaque infected from Sporothrix schenckii , which was possible transmitted from a cat. Observations A case of Thai woman presented with chronic painless ulcerated conjunctiva with white plaque. The lesion was not healed for one month after excision. She became concerned of getting infection from her cat because it developed chronic and multiple skin lesions on its legs. Identification of Sporothrix schenckii by PCR method was confirmed in the tissues from her conjunctiva and cat's skin. Conclusion and Importance The diagnosis of Sporothrix infection should be suspected in atypical conjunctival lesion in patient who had closed contact with infected cat. This brought awareness to doctors and cat owners, even though it was uncommon.

“…Currently, S. brasiliensis, S. schenckii, and Sporothrix humicola are the known causative agents of feline sporotrichosis [19,20,25,[39][40][41][42]. Cases of feline sporotrichosis were reported in the USA, Mexico, Argentina, Paraguay, Malaysia, Spain, Germany, Australia, Japan, Thailand, the UK, and Brazil [3-5, 17, 18, 41, 42].…”

“…As already commented, in Brazil, the main etiological agent of feline sporotrichosis is S. brasiliensis [23-25, 31, 45, 46]. In contrast, in some Asian countries, S. schenckii has been described as the causal agent of sporotrichosis in cats [39][40][41]47].…”

Guideline for the management of feline sporotrichosis caused by Sporothrix brasiliensis and literature revision

et al. 2020

View full text Add to dashboard Cite

We herein present a Brazilian guideline for the management of feline sporotrichosis, a mycosis caused by Sporothrix brasiliensis. This guideline is an effort of a national technical group organized by the Working Group on Sporothrix and Sporotrichosis of the International Society for Human and Animal Mycology (ISHAM). This publication intends to provide information on clinicalepidemiological aspects of this zoonosis, as well as a literature revision. Moreover, it gives some practical information on diagnosis and treatment of feline sporotrichosis. It also contains information that can be helpful for the prevention and control of S. brasiliensis transmission.

Background Lifestyle factors such as hair length, the frequency of ear cleaning and bathing, age, cat rearing, and sex may contribute to opportunistic yeast infections in the external ear canal of cats. This study aimed to determine the prevalence of commensal yeast organisms in cats’ external ear canals, evaluate their predisposing lifestyle factors, and test the susceptibility of Malassezia pachydermatis to antifungal agents. Results A total of 53 cats (33 male and 20 female) seronegative for feline leukemia virus and feline immunodeficiency virus were enrolled in this study. Their mean age (± standard deviation) was 6.04 (± 3.49) years. Fungal cultures and polymerase chain reaction tests were performed to identify the yeast species derived from the external ear canal. The association between lifestyle factors and the presence of M. pachydermatis was evaluated using Fisher’s exact test. The susceptibility of M. pachydermatis to antifungal agents was also analyzed. M. pachydermatis was the most frequently recovered yeast species, with a prevalence of 50.94 % (95 % confidence interval [CI]: 36.84–64.94 %). There was an association between hair length and a positive culture for M. pachydermatis (p = 0.0001). The odds of a negative culture for M. pachydermatis among short-haired cats was 11.67 (95 % CI, 3.22–42.24) times higher than that among long-haired cats (p = 0.0002). There was also an association between the frequency of ear cleaning and the presence of M. pachydermatis (p = 0.007). The odds of a negative culture for M. pachydermatis in cats that were receiving ear cleaning at intervals of ≤ 2 weeks was 5.78 (95 % CI, 1.67–19.94) times greater than that of cats receiving ear cleaning at intervals greater than 2 weeks or never (p = 0.0055). Ranges of minimum inhibitory concentrations (MICs) and minimum fungicidal concentrations for itraconazole, ketoconazole, miconazole, and terbinafine against M. pachydermatis were ≤ 0.063–4 and ≤ 0.063–≥32, ≤ 0.063–8 and 0.125–≥32, ≤ 0.063–≥32 and 0.5–≥32, and ≤ 0.016–1 and 0.125–8 µg/ml, respectively. Conclusions M. pachydermatis was the most commonly identified yeast organism in the external ear canal of healthy cats. Hair length and the frequency of ear cleaning played a role in the colonization of M. pachydermatis. The M. pachydermatis isolates had various MIC levels for common fungicides.
