Amino sugars are a kind of carbohydrates with one or more hydroxyl groups replaced by an amino group. They play crucial roles in a broad range of biological activities. (Yang J, Xie D, Ma X. Recent Advances in Chemical Synthesis of Amino Sugars. Molecules. 2023; 28(12):4724. https://doi.org/10.3390/molecules28124724)

Gum resins are mixtures of both true gums and resins and naturally combine the traits of both groups. (http://www.faculty.ucr.edu/~legneref/botany/gumresin.htm)

Chlamydophila psittaci (formerly avian Chlamydia psittaci) is the causative agent of psittacosis, a systemic disease in psittacine birds which can be of acute, protracted, chronic, or subclinical manifestation and which represents the most important animal chlamydiosis of zoonotic character. Avian strains are pathogenic to humans. (Adapted from Goellner, S., Schubert, E., Liebler-Tenorio, E., Hotzel, H., Saluz, H. P., & Sachse, K. (2006). Transcriptional response patterns of Chlamydophila psittaci in different in vitro models of persistent infection. Infection and immunity, 74(8), 4801–4808. https://doi.org/10.1128/IAI.01487-05)

Gum is a sap or other resinous material associated with certain species of the plant kingdom. This material is often polysaccharide-based and is most frequently associated with woody plants, particularly under the bark or as a seed coating. (https://en.wikipedia.org/wiki/Gum_(botany))

Ribotyping is a molecular technique for bacterial identification and characterization that uses information from rRNA-based phylogenetic analyses. (https://en.wikipedia.org/wiki/Ribotyping)

Gutta-percha is purified, coagulated latex obtained from trees of the genera Palaquium and Payena (Sapotaceae), which are found both wild and cultivated in Malaysia and Indonesia.

The pear psylla, Cacopsylla pyricola (Forster) (Hemiptera: Psyllidae), is a major economic pest of pears across North America and Europe. The primary economic damage caused by C. pyricola is fruit russetting, which results from honeydew on the fruit that is produced by the psylla nymphs.
