AI Article Synopsis

  • - The study investigates the prevalence and genetic characteristics of a common enteric protist in giant pandas, red pandas, and various bird species in southwestern China, addressing gaps in previous research on these animals.
  • - A total of 168 fecal samples were analyzed, revealing an overall prevalence of 11.3%, with the highest rates found in ruddy shelducks (18.2%) and the lowest in green peafowls (6.7%).
  • - Two zoonotic subtypes (ST1 and ST8) were identified, with ST1 being more common, particularly in older giant pandas, marking this as the first study to report these findings in the specified animal species in China.

Article Abstract

is a common enteric protist that colonizes humans and a wide range of animals. Although some studies have reported incidences of in humans and animals in China, there is no information available on the prevalence of in giant pandas, red pandas, or bird species. The aims of the present study were to determine the prevalence, subtype distribution, and genetic characterizations of in these animals in a captive situation in southwestern China, as well as assess the zoonotic potential of isolates. A total of 168 fecal specimens, including 81 from giant pandas, 23 from red pandas, 38 from black swans, 11 from ruddy shelducks, and 15 from green peafowl were collected at the Chengdu Research Base of Giant Panda Breeding in Sichuan province. The overall minimum prevalence of was 11.3% (19/168) based on PCR amplification of the barcode region of the SSU rRNA gene. The highest prevalence of was observed in ruddy shelduck (18.2%) and the lowest was found in green peafowl (6.7%). The prevalence of in giant pandas >5.5 years of age was higher than that in younger giant pandas. Two potentially zoonotic subtypes (ST1 and ST8) were identified, and ST1 (n = 12) was found to be more prevalent than ST8 (n = 7). To the best of our knowledge, this is the first report of the prevalence and subtypes of in giant pandas, red pandas, and bird species in China. The findings of this study will improve our understanding of the genetic diversity and public health potential of

Grazing-Induced Habitat Degradation: Challenges to Giant Panda Survival Resulting from Declining Bamboo and Soil Quality.

Animals (Basel)

January 2025

Key Laboratory of Southwest China Wildlife Resources Conservation (Ministry of Education), China West Normal University, Nanchong 637009, China.

Grazing is the primary human-induced disturbance affecting giant panda () habitats and has a severe impact on the long-term sustainability of the giant panda population. To address the lack of quantitative studies on grazing's impact on habitat quality, we selected China's most heavily grazed giant panda nature reserve. Utilizing the Maxent model and stoichiometric analysis, we investigated habitat quality degradation caused by grazing and quantified changes in bamboo nutritional quality and soil physicochemical properties.

Relationship Between Population Size and Habitat Area of Giant Pandas in China.

School of Ecology and Nature Conservation, Beijing Forestry University, Beijing 100083, China.

This study analyzed survey result data of giant panda populations and habitats in the third and fourth giant panda surveys to reveal the population size-habitat area relationship and assess the habitat status at the county and nature reserve levels. Results showed that a significant linear relationship existed between the logarithm of population size (lnS) and the logarithm of habitat area (lnA), with an equation of lnS = 1.145 × lnA - 4.

Babesia species (Piroplasmida) are hemoparasites that infect erythrocytes of mammals and birds and are mainly transmitted by hard ticks (Acari: Ixodidae). These hemoparasites are known to be the second most common parasites infecting mammals, after trypanosomes, and some species may cause malaria-like disease in humans. Diagnosis and understanding of Babesia diversity increasingly rely on genetic data obtained through molecular techniques.

To fully characterize papillomavirus diversity in giant pandas (), we identified a novel papillomavirus (named AmPV5, GenBank accession number MZ357114) in oral swabs from giant pandas with the help of viral metagenomics technology in this study. The complete circular genome of AmPV5 is 7,935 bp in length, with a GC content of 39.1%.
