3.12.1. Trichinella patagoniensis in the Americas

Trichinella patagoniensis has a mild freeze-tolerance, with larvae surviving in the tissue of an experimentally infected domestic cat ( Felis silvestris ) frozen at – 5 ◦ C for 3 months, but did not survive freezing at – 18 ◦ C for 1 week ( Krivokapich et al., 2012). Domestic cats and, to a lesser extent, guinea pigs ( Cavia porcellus ) can be experimentally infected, while experimental infections in domestic pigs, wild boars, rats, mice ( Mus musculus ), and chickens ( Gallus gallus domesticus ) were relatively unsuccessful (Farina ˜et al., 2017; Krivokapich et al., 2012; Pasqualetti et al., 2014; Ribicich et al., 2013). Trichinella patagoniensis has only been detected in three cougars from Argentina thus far which highlights the need for further surveillance in Argentina and surrounding countries in South America. To date, there have been no reported human infections attributed to T. patagoniensis .
