Answer :
Final answer:
The 'walking dandruff mite,' likely refers to demodex skin mites, microscopic symbiotic creatures living on human skin. While dandruff is commonly caused by the yeast Malassezia globosa, and not directly by these mites, skin mites can sometimes contribute to other skin issues. Common household dust mites are a separate species that can trigger asthma but are not the same as demodex mites.
Explanation:
The walking dandruff mite refers to a type of skin mite, specifically from the genus Demodex, which are common microscopic inhabitants of human skin. Although the term 'walking dandruff' can colloquially refer to cheyletiellosis, a condition caused by a different type of mite, in the context of your question and the provided information, we are focusing on demodex mites, particularly D. folliculorum and D. brevis. These mites are part of the human skin's microbiota, living symbiotically and feeding on the lipids in the sebaceous regions. Usually, they do not cause harm, but they can sometimes contribute to skin conditions.
Another skin-related organism is Malassezia globosa, a yeast responsible for conditions like tinea versicolor and dandruff. This yeast is part of the skin's natural flora but can sometimes overgrow and lead to skin pigmentation changes or dandruff. While dandruff is often associated with flakiness, it is technically different from the issues caused by the mites of the Demodex genus.
Common house dust mites, though related, are different from the skin-inhabiting mites and mainly cause concern due to their feces, which can trigger asthma attacks. These dust mites, despite thorough cleaning, are virtually impossible to eradicate from homes.
