Trichinella spiralis is a zoonotic tissue-dwelling parasitic nematode that infects humans and other mammals. Its surface proteins are recognized as antigenic in many infected hosts, being directly exposed to the host’s immune system and are the main target antigens that induce the immune responses. (Cui, J., Liu, R.D., Wang, L. et al. Proteomic analysis of surface proteins of Trichinella spiralis muscle larvae by two-dimensional gel electrophoresis and mass spectrometry. Parasites Vectors 6, 355 (2013). https://doi.org/10.1186/1756-3305-6-355)
Bulbs usually grow just below the surface of the ground and produce a fleshy, leafy shoot above ground. Bulbs usually consist of layers, or clustered segments. Examples garlic, onion, leek, shallot, spring onion and fennel. (https://www.vegetables.co.nz/vegetable-classification/bulbs/)
