Which organism is included in the CNHL acronym for conditions that can penetrate an intact corneal epithelium?

The correct answer is Corynebacterium diphtheriae. This organism is part of the CNHL acronym, which stands for the types of pathogens known to penetrate an intact corneal epithelium. Corynebacterium diphtheriae is notable for being an organism that can cause infections in primarily soft tissue areas, and in certain rare cases, it can affect the eye, particularly if there's a breakdown in normal barriers, such as when the corneal epithelium is compromised.

Understanding the role of Corynebacterium diphtheriae in eye infections highlights its potential for pathogenicity in various tissues beyond its most well-known effects relating to diphtheria. In contrast, while the other choices may cause eye infections or other types of illnesses, they do not belong to the same group of organisms classified under the CNHL acronym regarding the capability to penetrate an intact corneal epithelium. Therefore, knowing the associations of specific bacteria with corneal infections is important for correctly identifying potential ocular pathogens in clinical situations.
