“…Neospora caninum have also been reported in this species in Argentina(Dellarupe et al 2019, Salcedo et al 2021). However, despite numerous parasitological studies conducted on all these rodent species in Argentina, no reports of Sarcocystis spp.…”

The occurrence of Sarcocystis species was investigated in synanthropic (Muridae) and wild (Cricetidae) rodents from Argentina. Nine species were captured (n = 356). Sarcocysts were detected in muscles of 8.7% (31/356) and 3.7% (4/106) of the rodents by histopathology and direct microscopy, respectively. PCRs-sequencing targeting the 18S rRNA, cox1 and ITS1 regions were performed on samples with positive histopathology. Four different 18S rRNA sequences or sequence groups with high intra-group identities (99.6-100%) were detected in Mus musculus, Oxymycterus rufus, Akodon azarae and Necromys lasiurus. Eight sequences showed 99.5-99.7% identity with S. dispersa. Thirteen sequences showed low identity (95.3-96.4%) with other Sarcocystis spp. The obtained coxI sequences (n = 9) were almost identical among them and showed a high similarity with S. strixi (99.2-99.5%) and S. lutrae (99.1%), despite the 18S rRNA sequences from the same samples suggested the occurrence of at least two species. This suggests that coxI may not show high variability in Sarcocystis spp. that use rodents as intermediate hosts. Six ITS1 sequences were obtained, showing high identity but low coverage with several Sarcocystis spp. Multilocus sequence typing and BLAST analysis did not allow accurate species identi cation. Possible reasons are the detection of new species or the lack of molecular information from previously described ones. Phylogeny suggests that the detected Sarcocystis spp. may use raptor birds or snakes as de nitive hosts. This study represents the rst molecular identi cation of Sarcocystis spp. in naturally infected rodents of the Cricetidae and Muridae families in South America.

“…PICV has a similar viral genome structure as LCMV, but unlike LCMV that is found worldwide because its reservoir is the common house mouse of the genus Mus musculus (140,141). PICV is found in rice rats of the genus oryzomys albigularis that is endemic only in the Pichinde valley of Colombia, South America (121,142).…”

Advances in Development and Application of Influenza Vaccines

Influenza A virus is one of the most important zoonotic pathogens that can cause severe symptoms and has the potential to cause high number of deaths and great economic loss. Vaccination is still the best option to prevent influenza virus infection. Different types of influenza vaccines, including live attenuated virus vaccines, inactivated whole virus vaccines, virosome vaccines, split-virion vaccines and subunit vaccines have been developed. However, they have several limitations, such as the relatively high manufacturing cost and long production time, moderate efficacy of some of the vaccines in certain populations, and lack of cross-reactivity. These are some of the problems that need to be solved. Here, we summarized recent advances in the development and application of different types of influenza vaccines, including the recent development of viral vectored influenza vaccines. We also described the construction of other vaccines that are based on recombinant influenza viruses as viral vectors. Information provided in this review article might lead to the development of safe and highly effective novel influenza vaccines.
