Human injury due to porcupine quill attack is quite unusual, as their interaction is very rare owing to their habitat. However encroachment into their wildlife can cause grave injuries due to their quills, which are modified keratin having backward facing sharp barbs. The injuries resulting from porcupine quill may cause pain, infection, foreign body reactions, vascular trauma, gastric perforations and are difficult to retrieve because of their structure. Limited literature report exists of porcupine quill injuries in humans, but the maxillofacial injuries secondary to quill attack is an absolute rarity. In this case report, we describe the mechanism of injury, management, complications along with review of literature which makes it an interesting read.

Article Synopsis
  • The Sunda porcupine, a rodent species native to Indonesia, is used in traditional medicine for treating ailments like back pain and toothache, though scientific research on its medicinal properties is limited.
  • This study aimed to identify active compounds in the ethanolic extract of Sunda porcupine quills and assess their antioxidant and antimicrobial activities, employing various assays for evaluation.
  • The results revealed the extract has significant antioxidant (IC 138.93 μg/mL) and antimicrobial properties against several bacterial strains, with 24 active compounds identified, including notable antioxidants and antimicrobial agents like butylated hydroxytoluene and eicosane.

New World porcupines (Erethizontidae) exhibit behaviors and possess integumentary structures, including the quills, that are used for self-defense. The North American porcupine (Erethizon dorsatum) has been well studied regarding these features; however, information is lacking for the South American Coendou species. We describe the defensive behavior and integumentary morphology of Coendou spinosus to understand the defensive strategies of this species and to compare with those reported for other species.

The North American (NA) porcupine () is a rodent species with specialized hair structures called quills designed to detach and penetrate into tissues of any human or animal coming into contact with them. The objective of this study was to characterize the fungal flora of the quills in the region of the rosette in wild NA porcupines to further define health risks to NA porcupines and any animal coming into contact with the quills. A total of 17 adult NA porcupines were sampled, and fungal culture was performed.

The mechanical properties of porcupine quills have attracted the interest of researchers due to their unique structure and composition. However, there is still a knowledge gap in understanding how these properties can be utilized to design biomimetic structures with enhanced performance. This study delves into the nanomechanical and macro-mechanical properties of porcupine quills, unveiling varied elastic moduli across different regions and cross sections.
