An adult specimen of Cavia aperea was transferred to the Wild Animal Practice, in the Department of Wildlife and Natural Environment, Faculty of Veterinary Sciences, National University of Asunción. Fecal samples and necropsy samples revealed the presence of Paraspidodera uncinata in the digestive tract, and Gyropus ovalis. This is the first documented report of the presence of P. uncinata and G. ovalis in a wild specimen of Cavia aperea in Paraguay.

Background: In this study, we described the anatomy of the brachial plexus of the guinea pig (Cavia porcellus). The description of the brachial plexus anatomy can contribute to the knowledge of the neuroanatomy of small mammals. Furthermore, it is a source of information for clinicians performing brachial plexus anesthesia in exotic animals such as the guinea pig (Cavia porcellus).

Unlabelled: There are four genogroups and 18 genotypes of human sapoviruses (HuSaVs) responsible for acute gastroenteritis. To comprehend their antigenic and virological differences, it is crucial to obtain viral stocks of the different strains. Previously, we utilized the human duodenum-derived cell line HuTu80, and glycocholate, a conjugated bile acid, to replicate and propagate GI.

The ciliary muscle constitutes a crucial element in refractive regulation. Investigating the pathophysiological mechanisms within the ciliary muscle during excessive contraction holds significance in treating ciliary muscle dysfunction. A guinea pig model of excessive contraction of the ciliary muscle induced by drops pilocarpine was employed, alongside the primary ciliary muscle cells was employed in in vitro experiments.

The present study aims to establish the morphological, morphometric, and immunostaining patterns of the steroidogenic enzymes 17β-HSD and 5α-reductase and androgen receptors (AR) during the prenatal development of the male gonad and epididymis of Cavia porcellus. Fetuses at 22, 25, 30, 40, 45, 50, and 60 days of gestation (DG) were used. Specimens were dissected and subjected to macroscopic, histological, histomorphometric, and immunohistochemical analyses.
