All of the following statements about thrush are true EXCEPT
1. It is caused by a gram-negative fungus
2. It is characterized by a plaque of proliferating epithelial and other cells
3. It is a complication of immunosuppression or systemic disease
4. It can affect neonates in an epidemic fashion
Oral Pathology
Answer: 1
Explanation:
It is caused by a gram-negative fungus: This statement
is not true. Thrush is caused by Candida albicans,
which is a yeast (fungus) but not a gram-negative organism. In fact, fungi
are not classified as gram-positive or gram-negative in the same way that
bacteria are. Candida is a eukaryotic organism and does not fit
into the gram classification system.
It is characterized by a plaque of proliferating epithelial and
other cells: This statement is true. Thrush
presents as white patches or plaques in the oral cavity, which consist of
fungal elements, dead epithelial cells, and inflammatory cells.
It is a complication of immunosuppression or systemic disease:
This statement is true. Thrush is commonly seen in
individuals who are immunocompromised, such as those with HIV/AIDS, cancer
patients undergoing chemotherapy, or individuals on long-term corticosteroid
therapy.
It can affect neonates in an epidemic fashion: This
statement is true. Thrush can indeed affect neonates,
particularly those born to mothers with vaginal candidiasis, and outbreaks
can occur in neonatal intensive care units.
