The key to egress? Babesia bovis perforin-like protein 1 (PLP1) with hemolytic capacity is required for blood stage replication and is involved in the exit of the parasite from the host cell.

Bovine babesiosis is a tick-borne disease caused by apicomplexan parasites of the Babesia genus that represents a major constraint to livestock production worldwide. Currently available vaccines are based on live parasites which have archetypal limitations. Our goal is to identify candidate antigens so that new and effective vaccines against Babesia may be developed.

Ancient parasitic DNA reveals presence in Final Pleistocene of South America.

Parasitological analysis of coprolites has allowed exploring ecological relationships in ancient times. Ancient DNA analysis contributes to the identification of coprolites and their parasites. Pleistocene mammalian carnivore coprolites were recovered from paleontological and archaeological site Peñas de las Trampas 1.

First mitochondrial and nuclear DNA sequences of Lamanema chavezi (Nematoda: Molineidae): Novel findings to improve its identification in feces from South American camelids.

Lamanema chavezi (Family Molineidae) is a parasitic nematode of South American camelids (SACs). A few studies have reported this parasite in SACs, mainly in domestic camelid species (llama and alpaca). Parasite identification by means of copro-parasitological methods is non-invasive and allows performing epidemiological studies.

Fox parasites in pre-Columbian times: Evidence from the past to understand the current helminth assemblages.

This work aims to increase the information on the entero-parasitism in Holocene carnivores, by examining coprolites found in Patagonia. Molecular analysis was conducted following the Authenticity Criteria to Determine Ancient DNA sequences. The nucleotide sequences showed 99% of identity with the Control Region sequences of Lycalopex culpaeus (culpeo fox).

First morphological and molecular analysis of Eucoleus boehmi like eggs in dogs from Argentina.

The canid parasites Eucoleus aerophilus (syn. Capillaria aerophila) and Eucoleus boehmi (syn. Capillaria boehmi) parasitize the lower and the upper respiratory tract, respectively.
