Scanning electron microscopy of the nasal skin in different animal species as a method for forensic identification.

Abstract: The current study aims to provide a new method for the identification of animal species by using the scanning electron microscopic study on the nasal skin around the nostril. The reference databases for animal identification using traditional ways (i.e., hair and bone analyses) were somewhat available. This study was conducted on the nasal skin of seven different animal species: large ruminants (Saidi buffalo and frozen Angus cattle); small ruminants (Egyptian goat and Rahmani sheep); camels (one-hump dromedary camel); equines (African domestic donkey and Arabian horse); carnivores (farm domestic cat, Egyptian Baladi dog, and red fox); swine (Danish Landrace pig); and rodents (albino rat and New Zealand white rabbit). The nasal skin was divided by grooves into different shaped raised areas in some examined animals, the mean diameter of these areas and width of the grooves of each animal species were recorded. The characteristic differential features of the nasal skin of each animal species have been documented. Few openings of the nasolabial glands were demonstrated in large ruminants and swine, which were H letter-shaped in buffaloes, oval-shaped in cattle, and whirlpool-shaped with several layers of folds on their margin in pig. Moreover, the openings of the lateral nasal glands were whirlpool, ovoid, and oval shaped in goats, sheep, and camels, respectively. In conclusion, the present study proved that the skin around the nostrils plays an important role as means of identification in forensic investigations and improves the field of veterinary forensic medicine in general, which is not well-developed in comparison with human forensics.

The research focuses on a novel approach to identify animal species by scanning the skin around the nostril using electron microscopy. The study involved the examination of seven different animal species, with the findings suggesting the potential for this method in forensic investigations and veterinary forensics.

Objective of the Study

  • The main objective of this research was to discover a new method for the identification of animal species. The researchers used scanning electron microscopic study on the nasal skin around the nostril, an area that has been less researched for species identification purposes.

Methodology

  • The study was conducted on a variety of animals including large ruminants like Saidi buffalo and Angus cattle, small ruminants like Egyptian goat and Rahmani sheep, a camel, equines like African domestic donkey and Arabian horse, carnivores like farm domestic cat, Egyptian Baladi dog, and red fox, swines, and rodents.
  • The nasal skin of these animals was examined, specifically focusing on the grooves and raised areas. The mean diameter of these raised areas and the width of the grooves for each of the animal species were recorded.

Findings

  • The researchers documented unique features of the nasal skin for each animal species, suggesting that these could be used for species identification. They also observed the openings of the nasolabial glands in large ruminants and swines, which presented unique shapes across different species.
  • For instance, the openings were H letter-shaped in buffaloes, oval-shaped in cattle, and whirlpool-shaped with folded margins in pigs. The openings of the lateral nasal glands in goats, sheep, and camels were also discriminated based on their special shapes.

Conclusion

  • The results from this study indicated that the skin around the nostrils could be a significant identifier for forensic investigations. By applying scanning electron microscopy, the field of veterinary forensic medicine could develop further, given that it has been relatively less explored compared to human forensics.
