Quantitative and qualitative histological evaluation of different regions of cryopreserved skin derived from red-rumped agouti for obtaining cryobanks.

Skin banks are valuable tools for the maintenance of biodiversity. The red-rumped agouti is a wild rodent of ecological importance in South America because it acts as a seed disperser, and skin banks could serve as alternatives to conserve genetic variability. Nevertheless, the most suitable skin region for forming these banks must still be determined to guarantee tissue quality after cryopreservation.

Influence of cryopreservation techniques and low concentrations of permeating cryoprotectants on the conservation of ear cartilage and skin derived from six-banded armadillos (Euphractus sexcinctus Linnaeus, 1758).

Considering the importance of efficiently obtaining somatic resource banks as an ex-situ conservation strategy for wild mammals, we evaluated two techniques (slow freezing - SF and solid-surface vitrification - SSV) for the cryopreservation of ear cartilage and skin from six-banded armadillos. Additionally, we analyzed the effects of two combinations of intracellular cryoprotectants (3.0 M or 6.

Cutaneous and conjunctival habronemosis in horses treated at the Veterinary Hospital of the Santa Catarina State University, Brazil.

Habronemosis, also known as habronemiasis or habronematidosis, is a parasitic disease of equids caused by the larval stages of Habronematidae nematodes (Habronema muscae, Habronema microstoma, and Draschia megastoma) that are transmitted by muscid flies. The presence of aberrant infective larvae in the cutaneous and conjunctival tissues of these hosts results in granulomatous, exudative, and ulcerated lesions, also known as "summer sores." In this study, we present a retrospective analysis of habronemosis cases in horses from the municipality of Lages, located on the Santa Catarina Plateau, a region with high altitudes and a temperate climate that differs from regions of Brazil where such parasitosis usually occurs.

Investigating cryopreservation techniques for maintaining morphology and in vitro viability of cartilage and skin from Spix's yellow-toothed cavies (Galea spixii Wagler, 1831) for conservation through biobanks.

Conservation of the genetic diversity through skin and cartilage biobanks represents an essential strategy for maintaining biodiversity. Biobanks for the wild species of the order Rodentia have been little studied. Considering that the cryopreservation technique has specific relationships with the tissue and species of interest, we propose investigating different techniques for preserving tissue integrity and cell viability after cartilage and skin culture from Spix's yellow-toothed cavies.
