Article Synopsis
- - The study investigated the presence of antibodies to 13 livestock and zoonotic pathogens in 164 southern pudu deer in Chile from 2011 to 2023, revealing that 20.18% of wild and 30.91% of captive pudus showed exposure to these pathogens.
- - It found that fawn pudus are at a higher risk of infection compared to adults, and those living in free-range conditions are less likely to contract certain parasites.
- - This research marks the first evidence of livestock pathogen exposure in South American wildlife, indicating potential livestock-to-wildlife transmission in Chile’s temperate forests, and linking a past zoo outbreak to abortions among captive pudus.
In this study, we examined the in vitro invasion and proliferation capacities of the Nc-Liv and ten Spanish Neospora caninum isolates (Nc-Spain 1 H - Nc-Spain 10). The invasion rate was determined as the number of tachyzoites that completed their internalisation into MARC-145 cells at 2, 4, and 6 h post-inoculation (pi). The proliferation rate was evaluated by determining the doubling time during the exponential proliferation period.

However, the influence of Neospora caninum isolate itself has been poorly investigated. Here, we compared the effects on clinical outcome and vertical transmission observed in a pregnant mouse model following infection with 10 different N.

- Neospora caninum is primarily transmitted to cattle through transplacental infection, but there's a possibility of postnatal transmission via sporozoite-containing oocysts from dogs.
- A study tested for N. caninum DNA in semen from five Holstein-Friesian bulls infected with neosporosis, using nested-PCR and other methods to confirm infection.
- N. caninum DNA was found in small amounts in non-extended fresh semen and frozen semen straws of infected bulls, while control bulls showed no presence of the parasite, indicating more research is needed to explore venereal transmission routes.
