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

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.

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 ...

Novel genotypes of Hepatozoon spp. in small mammals, Brazil

Parasites & Vectors, 2022
Background Small mammals (rodents and marsupials) have been poorly explored for the occurrence of apicomplexan (genus Hepatozoon and genera of the order Piroplasmorida) and Anaplasmataceae agents in Brazil. Thus, this study investigated the occurrence of

Effect of Protein Supplementation in the Bee Apis mellifera L. Exposed to the Agrochemical Fipronil

Sociobiology, 2021
Inadequate quantity and quality of proteins in honey bee diet can cause weakening of their colonies and damage their resistance to agrochemical contamination, such as fipronil, which is highly toxic to bees.

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.
