Prevalence of Leptospira serogroups in buffaloes from the Brazilian Amazon

Veterinary Medicine and Science, 2020
Although Brazil has one of the largest buffalo populations in the Americas, buffalo leptospirosis is still poorly explored when compared to that in bovines; thus, the aim of this research was to carry out a large serological study for leptospirosis in ...

Molecular and Serological Detection of Coxiella burnetii in Small Ruminants in Northeastern Brazil

Veterinary Medicine and Science
Coxiella burnetii, the causative agent of Q fever in humans, is an important worldwide pathogen. The main reservoirs for the bacterium are ruminants, specifically sheep and goats, which act as major shedders of the bacterium in the environment.

Automated identification of spotted-fever tick vectors using convolutional neural networks. [PDF]

Med Vet Entomol
We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Bisphenols as promoters of the dysregulation of cellular junction proteins of the blood‐testis barrier in experimental animals: A systematic review of the literature

Journal of Biochemical and Molecular Toxicology, Volume 37, Issue 9, September 2023., 2023
Abstract Daily, people are exposed to chemicals and environmental compounds such as bisphenols (BPs). These substances are present in more than 80% of human fluids. Human exposure to BPs is associated with male reproductive health disorders. Some of the main targets of BPs are intercellular junction proteins of the blood‐testis barrier (BTB) in Sertoli

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.

Estudo da infecção por Rickettsias do grupo da febre maculosa em humanos e carrapatos de um parque urbano na Cidade de Londrina, Estado do Paraná [PDF]

, 2011
INTRODUCTION: Spotted fevers are emerging zoonoses caused by Rickettsia species in the spotted fever group (SFG). Rickettsia rickettsii is the main etiologic agent of Brazilian spotted fever (BSF) and it is transmitted by Amblyomma spp. ticks.
