Increased prevalence of canine echinococcosis a decade after the discontinuation of a governmental deworming program in Tierra del Fuego, Southern Chile

Zoonoses and Public Health, Volume 70, Issue 3, Page 213-222, May 2023., 2023
Abstract Hydatid disease is a neglected zoonotic parasitic disease caused by cysts of the tapeworm Echinococcus granulosus. Canids, especially domestic dogs, are definitive hosts of the parasite and are the most pragmatic targets for control programs. A governmental dog deworming campaign was established in 1979 to control hydatidosis in southern Chile,

Genetic diversity and kinship relationships in one of the largest South American fur seal (Arctocephalus australis) populations of the Pacific Ocean

Ecology and Evolution, Volume 11, Issue 13, Page 8743-8753, July 2021., 2021
Our results suggest that polygyny in South American fur seals is more relaxed than previously thought. Additionally, three full‐sibling pairs were genetically identified within the same breeding season, which is the first genetic support that describes the presence of twins for the species. These and genetic diversity attributes suggest that the colony

“Immunolocalization and effect of low concentrations of Insulin like growth factor‐1 (IGF‐1) in the canine ovary”

Veterinary Medicine and Science, Volume 7, Issue 1, Page 46-56, January 2021., 2021
The Insulin like growth factor‐1 (IGF‐1) was localized by immunohistochemistry in the canine ovary from 34 bitches. IGF‐1 and IGF‐1R were localized in all ovarian structures including the corpus luteum, but not in the follicular cells from primordial follicles in the canine ovary.

Evidence of Helicobacter spp. in Saliva and Gastric Mucosa of Domestic Dogs in the Central Region of Rio Grande do Sul, Brazil

Veterinary Medicine International, Volume 2021, Issue 1, 2021., 2021
Helicobacter pylori is a spiral‐shaped bacterium, which plays a role in the aetiology of gastric diseases in humans. Non‐H. pylori Helicobacter (NHPH) species naturally colonise the stomach of animals and also induce gastric lesions in humans, highlighting their zoonotic importance.
