The correct choice indicates that none of the statements provided about dermatomycosis are accurate. This suggests that each of the claims made in the other options does not reflect the true nature of dermatomycosis, which is a fungal infection of the skin caused by dermatophytes.

For the first statement regarding infected animals having several obvious lesions, it is important to note that dermatomycosis can manifest in varied ways. Some animals may present only a few lesions, or even have subclinical infections where no lesions are visible at all. Therefore, generalizing that infected animals typically exhibit several obvious lesions is misleading.

The second statement about one species of dermatophyte being common in animal facilities also lacks accuracy. While certain dermatophytes, such as Microsporum canis, are indeed prevalent in animal facilities, stating that there is only one common species oversimplifies the diversity of dermatophytes that can infect animals. It is crucial to acknowledge that multiple species can affect different animals and are often encountered in veterinary settings.

The claim about spores readily degrading in the environment doesn't hold true either. Dermatophyte spores are quite resilient and can persist in the environment for long periods, posing a risk for transmission. Thus, the understanding of their
