- Abstract
Introduction and Objectives: The dermatophyte pathogen Microsporum canis is a zoophilic dermatophyte which is transferred from dog and cat to human. Some properties of M. canis have been investigated so far; however, no information is available regarding the effects of CO2 on morphological patterns in this fungus. In this study we want to examine the environmental and iatrogenic factors such as CO2 on the growth and morphological aspects of M. canis. Materials and Methods: Strains used in this study were obtained from the patients with tinea capitis and tinea corporis and the spores have been isolated from samples by standard methods. Spores were cultured on Sabouraud dextrose broth (SDB) with pH 5.6 0.2± and incubated at 25°C for 2, 4 and 7 days under the 3%, 5% and 10% of CO2 concentrations. Control growth was maintained for 7 days without CO2 concentration. Results: The results of this study clarified the fact that the maximum variations under 3%, 5% and 10% of CO2 concentrations in maximum 7 days incubation period and the variations of morphological showed different variations under different CO2 concentration. Conclusion: Our result showed the additional effect of CO2 concentrations in the production of arthroconidia, chlamydoconidia and microconidia in M. canis comparing with the controls in all conditions during this study.
