The capybara eye: clinical tests, anatomic and biometric features.
Corneal thickness and axial length of the capybara are similar to that of human beings, revealing that the world's largest living rodent might be an excellent biological model for ophthalmic studies.
Reference values for the production of the aqueous fraction of the tear film measured by the standardized endodontic absorbent paper point test in different exotic and laboratory animal species.
The aqueous fraction of the tear film and the horizontal palpebral fissure length (HPFL) were measured in exotic and laboratory animals, specifically saffron finches, red-eared sliders, rats, rats and mice because these species possess small eyes making it difficult to perform the typical Schirmer tear test.
Measurement of tear production in black-tufted marmosets (Callithrix penicillata) using three different methods: modified Schirmer's I, phenol red thread and standardized endodontic absorbent paper
The palpebral fissure of black-tufted marmoset is very small and tear production is one of the lowest reported for all animal species, and a novel and practical alternative for tear production measurement using standardized endodontic absorbent paper points is presented.
Toxoplasma gondii in Capybara (Hydrochaeris hydrochaeris) antibodies and DNA detected by IFAT and PCR
The findings show a high percentage of infection with T. gondii in asymptomatic capybaras, and it is hypothesized that the consumption of raw or undercooked capybara meat could be a source of infection for humans.
Proven cardiac changes during death-feigning (tonic immobility) in rabbits (Oryctolagus cuniculus)
It is shown that TI is an alternative anti-predator behavior causing cardiac changes opposite to the “fight-or-flight” phenomenon, and it is proved that TI changes the cardiac function considerably.
[Seroprevalence of antibodies anti-Neospora caninum and anti-Toxoplasma gondii in captive wild canids].
The presence of these protozoans in captive wild canids species and to alert about possible contamination sources is shown and the presence of antibodies to N. caninum in bush dogs is demonstrated for the first time.
Hematology of the Red-Capped Parrot (Pionopsitta pileata) and Vinaceous Amazon Parrot (Amazona vinacea) in Captivity
For both Red-capped parrots and Vinaceous Amazon parrots, adult males had higher red blood cell counts than adult females and differences due to gender were also found for both species of parrots.
Evaluation of standardized endodontic paper point tear test in New Zealand white rabbits and comparison between corneal sensitivity followed tear tests.
Corneal touch threshold was significantly increased for at least 16 min after STT, indicating STT causes corneal discomfort, and the absence of a significant difference in CTT after PPTT compared with controls shows that P PTT is well tolerated by rabbits.
The eye of the red-eared slider turtle: morphologic observations and reference values for selected ophthalmic diagnostic tests.
PURPOSE To perform a descriptive investigation of the red-eared slider turtle (Trachemys scripta elegans) eye, performing selected ophthalmic diagnostic tests with the aim of establishing normal
