Prevalence of Malassezia pachydermatis in dogs with suspected Malassezia dermatitis or otitis in Slovakia

Abstract

The aim of the study was to evaluate the prevalence of yeast Malassezia pachydermatis in dogs from Slovakia in relation to different predisposition factors (sex, age, body localisation, hair type, and season). Samples of ear swabs (58) and dermal swabs (131) from 147 dogs with clinical symptoms of suspected yeast dermatitis and/or otitis, were examined between June 2005 to June 2007. Relatively higher prevalence of M. pachydermatis was found in samples taken from males (45.2%) than in females (35.2%), and in geriatric dogs (63.6%) than in young (42.5%) or adult (38.5%) dogs. Malassezia pachydermatis was isolated more often from ear swabs (44.8%) than from skin swabs (38.9%). Prevalence of M. pachydermatis was significantly higher (p < 0.05) in samples from the trunk area (60.3%) than in samples from other skin areas. Significantly higher prevalence was found in samples from long-haired (51.5%) and short-haired (45.9%) dogs compared to smooth-haired (21.4%) dogs. The prevalence was relatively higher in the samples taken in autumn (52.6%), than the other seasons: spring (36.1%), summer (27.3%), winter (45.7%); those differences were not significant. Malassezia pachydermatis is one of the most frequent yeasts isolated in dogs. Knowledge of factors predisposing to development of infection is valuable attribute of the correct diagnostic approach and case management.

Prevalence of Malassezia Infection in Dogs of Nagpur City

“…In the current study, males were found to be more susceptible to Malassezia, the prevalence in males was 60% against 40% in females, these findings are in complete agreement with the findings of Conkova et al, (2011) and Seetha et al, 2018. However, the results contradict the findings of Nardoni et al, 2004 who advocated no significant difference in the prevalence in both the sexes. The skewing of the incidence towards the males could be attributed to the fact that androgen triggers greater production of sebum Conkova et al, (2011) which predisposes the males to latent infection with Malassezia.…”

“…Both the sexes were found to be equally affected by Malassezia. The incidences are known to peak in summers due to high temperature of the tropical region Patterson and Frank (2002) while in the temperate climate the cases peak in the autumn Conkova et al, (2011). The prevalence was found to be highest in the age group of 1-3 years Girao et al, (2006).…”

Prevalence and Types of Fungi in Kintamani Bali Dogs

“…The prevalence findings based on sex was not very significant, maybe it need more sample and data analysis. Because according Conkova et al (2011), male dogs tend to be more susceptible to Malassezia infection than female dogs. The cause is the presence of androgen hormones in male dogs that increase sebum production, so the risk of fungal infection will rise.…”

Pilot study of dogs with suppurative and non-suppurative Malassezia otitis: A case series

“…Malassezia pachydermatis is commonly involved in canine otitis externa [1,2]. Changes in the microenvironment and defective host immunity seem to be associated with Malassezia overgrowth [3].…”
