Dynamics of food sources, ecotypic distribution and Trypanosoma cruzi infection in Triatoma brasiliensis from the northeast of Brazil. [PDF]

PLoS Neglected Tropical Diseases, 2020
Innovative approaches used to combat Chagas disease transmission tend to combine a set of comprehensive efforts to understand the ecology of local vectors. In this work we identified molecularly the blood meal of 181 Triatoma brasiliensis, distributed in

Effect of Epidermal Growth Factor and 6-Dimethylaminopurine on In Vitro Maturation and Artificial Activation of Spix’s Yellow-Toothed Cavy (Galea spixii Wagler, 1831) Oocytes [PDF]

Animals
The successful application of assisted reproductive technologies (ARTs), such as in vitro maturation (IVM) and artificial oocyte activation, requires species-specific adaptations. Although these methods are routinely used in laboratory rodents, their use

Domestic, peridomestic and wild hosts in the transmission of Trypanosoma cruzi in the Caatinga area colonised by Triatoma brasiliensis [PDF]

Memorias do Instituto Oswaldo Cruz, 2014
The role played by different mammal species in the maintenance of Trypanosoma cruzi is not constant and varies in time and place. This study aimed to characterise the importance of domestic, wild and peridomestic hosts in the transmission of T.

Prolonged use of letrozole causes morphological changes on gonads in Galea spixii. [PDF]

Anim Reprod, 2021
Letrozole is used as a therapeutic agent in reproductive disorders caused by high estrogen levels. Letrozole inhibits cytochrome P450 aromatase and reduces estrogen levels. However, the effects of long-term use on reproductive traits are unknown. The aim of this study was to evaluate the prolonged use of letrozole in the gonads of rodents (Spix's ...

Ultrastructural and morphometric description of the ear skin and cartilage of two South American wild histricognate rodents (Dasyprocta leporina and Galea spixii)

Pesquisa Veterinaria Brasileira, 2021
: Skin and cartilage have been the main source for the recovery of somatic cells to be used in conservation strategies in wild mammals. In this sense, an important step for the cryopreservation of these samples is to recognize the properties of the skin ...
