“…Shelters commonly reach for one of two options for confirmation testing. 11,12 Real-time PCR available through a commercial laboratory is moderately expensive but offers a diagnostic turnaround of 1–3 days. 13 Recent studies favorably compare PCR with culture for initial diagnosis, 11,14,15 but challenges exist in distinguishing mechanical carriers from truly infected cats using PCR.…”

“…Dermatophyte test medium (DTM) fungal culture with microscopic identification of fungal macroconidia has been considered the gold standard for dermatophytosis detection, 3,4 has been used by shelter clinicians to help distinguish infected from fomite carrier cats 1,4 and remains the best method for determining mycological cure. 11,12,15 However, turnaround time for DTM culture is very slow in a shelter context: the current literature recommends waiting 14–21 days before a plate is considered sufficiently diagnostic. 4,16,17…”

Objectives The aims of this descriptive study were to identify risk factors for feline Microsporum canis infection at shelter intake, to describe screening test accuracy, and to refine confirmatory testing time frames. Methods Database records for the general feline population and intake data, medical records and fungal culture logs for cats diagnosed with M canis at a limited admissions shelter were accessed retrospectively for a period of 2 years. Results The feline population at the study shelter had a prevalence of M canis of 1.8% (95% confidence interval [CI] 1.6–2.0%). Kittens were eight (95% CI 4.8–13.5) times more likely to present with dermatophytosis than adults. Although more cats presented with M canis during summer and autumn, season was not significant when the model was controlled for age. Owner-surrendered cats were half as likely (95% CI 0.41–0.77) as transported cats to be diagnosed with M canis. Wood’s lamp examinations had a sensitivity of 66.8% (95% CI 60.2–73.4) and a specificity of 74.8% (95% CI 64.2–85.1) compared with dermatophyte test medium (DTM) culture. In 78.8% (95% CI 61–91) of littermate or household groups with mixed Wood’s lamp results, all cats were DTM culture positive. Under consistent incubation conditions, 202/202 diagnostic DTM plates for M canis-infected cats showed recognizable colony growth before 7 days (median 4 days), and 19/19 fomite carrier cat cultures showed growth before 12 days (median 5 days). Conclusions and relevance Applying the results of this study to shelter protocols could optimize diagnostic approaches and shorten the length of stay for shelter cats and kittens, resulting in streamlined shelter operations and improved feline welfare.

Limited published data are available on dermatophytosis in zoo macropods, despite anecdotal reports of disease occurrence and recurrent mob outbreaks. The aim of this questionnaire study was to analyze data from Australian and international zoos to evaluate estimated disease prevalence in zoos housing macropods, affected macropod species, causative organisms, predisposing factors, clinical presentations, diagnostics, treatments, and disease risk management. Two questionnaires (initial detailed and subsequent brief) were distributed via email to zoo veterinarians, with an estimated response rate of 23%. The overall estimated disease prevalence from responding zoos was 28%, with 73% of responding Australian zoos and 14% of responding non-Australian zoos reporting disease. The first cases of confirmed and suspected dermatophytosis in several macropod species and in association with Trichophyton verrucosum and Trichophyton mentagrophytes var. nodulare are reported, with young red kangaroos (Macropus rufus) appearing predisposed. Diagnosis was most commonly based on fungal culture or presumptively on typical clinical signs of minimally/nonpruritic alopecia, crusting, and scaling distributed most frequently on the tail, pinnae, and hind limbs. Both disease resolution without treatment and resolution after an average of 1 to 2 mo of treatment were reported.
