Biochemical parameters, oxidative stress biomarkers, and anatomopathological changes in Wistar rats treated with 3'-demethoxy-6-O-demethylisoguaiacin and norisoguaiacin.

Artemisia cina (Ac) is a plant with anthelmintic compounds such as 3'-demethoxy-6-O-demethylisoguaiacin (D) and norisoguaiacin (N). Three major objectives were proposed: (1) To evaluate biochemical parameters in blood (2) to determine the tissue oxidative stress by biomarkers as TBARS and glutathione peroxidase activity, and (3) to evaluate anatomopathological changes in organs such as the brain, liver, kidney, and lung after oral administration of n-hexane extract of Ac and D and N. D and N were administrated following the OECD guides for acute oral toxicity evaluation (Guide 420).

is widely prevalent in sheep and their products pose a risk to public health. The aim of this study was to identify the seroprevalence and risk factors associated with infection in sheep in Veracruz State, Mexico. The study was cross-sectional and it was carried out in thirteen municipalities distributed in three regions of Veracruz State.

[Epidemiology of caprine brucellosis in the Central Zone of the State of Veracruz].

Introduction: Brucellosis is a disease of high morbidity that affects several animal species, is transmitted to humans and, therefore, is a zoonosis. It is caused by bacteria of the genus Brucella. In this study we aim to determine seroprevalence, risk factors, and spatial distribution of caprine brucellosis in 14 municipalities in the central region of the state of Veracruz.

Detection and phylogenetic analysis of bovine papillomavirus in cutaneous warts in cattle in Tamaulipas, Mexico.

Papillomas occur more frequently in cattle than other domestic animals. The causal agent of bovine papillomatosis is a virus that belongs to the family In Tamaulipas, Mexico, the virus is considered a serious problem and has impeded the export of cattle to the United States, resulting in serious economic losses. Owing to the lack of information regarding the subtypes of papillomaviruses that infect cattle in Mexico, the aim of this study was to determine the subtypes in Tamaulipas.
