| trichinella patagoniensis n. sp. (nematoda), a new encapsulated species infecting carnivorous mammals in south america. | until a few years ago, trichinella spiralis was the only taxon of the genus trichinella detected in both domestic and wild animals of south america. recently, a new genotype, named trichinella t12, was identified in cougars (puma concolor) from argentina, on the basis of molecular studies using mitochondrial and nuclear ribosomal markers. in the present study, cross-breeding experiments indicated that trichinella t12 is reproductively isolated from all other encapsulated trichinella spp. and sug ... | 2012 | 22921601 |
| susceptibility of chickens (gallus gallus domesticus) to trichinella patagoniensis. | trichinella spp. is a genus of parasites that is widespread all over the world. in argentina, t. spiralis was for years the only species involved in human and animal outbreaks. during the last decade, t. patagoniensis, a new trichinella species, was discovered in argentina. up to now, this species has only been found in cougars (puma concolor). experimental infections in pigs, cats, mice and rats with this new genotype showed that cats and mice were the most susceptible hosts. the aim of the pre ... | 2014 | 25123612 |
| evaluation of the infectivity and the persistence of trichinella patagoniensis in muscle tissue of decomposing guinea pig (cavia porcellus). | trichinella patagoniensis, a new species of trichinella, is widespread in argentina. the success of parasite transmission depends, among other factors, on the resistance of l1 larvae present in the muscle tissue (ml) of dead hosts undergoing the decomposition process in different environmental conditions. the aim of the present work was to study the infectivity of t. patagoniensis muscle larvae in cavia porcellus and the capability of the parasite to survive in decomposed muscle tissue of guinea ... | 2017 | 27771802 |
| [assessment of transmammary transmission of trichinella patagoniensis in balb/c mice]. | since 1916 to date, it has been suspected that vertical transmission of parasites from the genus trichinella could occur in pregnant or lactating women during the parenteral phase of infection. the aim of the present study was to evaluate the transmammary transmission of t. patagoniensis in balb/c mice. twenty 7-week-old balb/c mice were distributed into two groups of 10 individuals each, depending on the time of gestation when they were infected, 15 or 18 days after detection of the vaginal plu ... | 2017 | 27091152 |
