Molecular phylogenetic analysis of the genus Gloydius (Squamata, Viperidae, Crotalinae), with description of two new alpine species from Qinghai-Tibet Plateau, China [PDF]

open access: yesZooKeys, 2021
We provide a molecular phylogeny of Asian pit vipers (the genus Gloydius) based on four mitochondrial genes (12S, 16S, ND4, and cytb). Sequences of Gloydius himalayanus, the only member of the genus that occurs south of the Himalayan range, are included ...

A novel missense mutation in the gene encoding major intrinsic protein (MIP) in a Giant panda with unilateral cataract formation

open access: yesBMC Genomics, 2021
Background Cataracts are defects of the lens that cause progressive visual impairment and ultimately blindness in many vertebrate species. Most cataracts are age-related, but up to one third have an underlying genetic cause.

Comparative proteomics in captive giant pandas to identify proteins involved in age-related cataract formation

open access: yesScientific Reports, 2023
Approximately 20% of aged captive giant pandas (Ailuropoda melanoleuca) have cataracts that impair their quality of life. To identify potential biomarkers of cataract formation, we carried out a quantitative proteomics analysis of 10 giant pandas to find

Mechanism of inulin in colic and gut microbiota of captive Asian elephant

open access: yesMicrobiome, 2023
Background Gut microbiota have a complex role on the survivability, digestive physiology, production, and growth performance in animals. Recent studies have emphasized the effects of prebiotics therapy on the gut disease, but the relationship between ...

A novel missense mutation in the HSF4 gene of giant pandas with senile congenital cataracts

open access: yesScientific Reports, 2021
Cataracts are a common cause of visual impairment and blindness in mammals. They are usually associated with aging, but approximately one third of cases have a significant genetic component. Cataracts are increasingly prevalent among aging populations of

Comparative study of the gut microbiota in three captive Rhinopithecus species

open access: yesBMC Genomics, 2023
Background Snub-nosed monkeys are highly endangered primates and their population continues to decline with the habitat fragmentation. Artificial feeding and breeding is an important auxiliary conservation strategy.

Effects of Microalgal Food Quantity on Several Productivity-Related Parameters of the Calanoid Copepod Bestiolina similis (Calanoida: Paracalanidae)

open access: yesFrontiers in Marine Science, 2021
The optimization of copepod feeding protocol is paramount to improve culture productivity and to maintain favorable water quality parameters overtime, as well as saving operational costs by preventing the production of unnecessary quantities of ...

A rare case of giant panda cancer: Pancreatic ductal adenocarcinoma

open access: yesAnimal Models and Experimental Medicine, 2022
Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant cancer of the digestive system common among humans. However, it is rarely reported in wild animals. In 2018, a giant panda died in the Beijing Zoo.

SARS-CoV-2 Infection in Captive Hippos (Hippopotamus amphibius), Belgium

open access: yesAnimals, 2023
Two adult female hippos in Zoo Antwerp who were naturally infected with SARS-CoV-2 showed nasal discharge for a few days. Virus was detected by immunocytochemistry and PCR in nasal swab samples and by PCR in faeces and pool water.
