Title: Detection and Genetic Characterization of Viruses Present in Free-Ranging Snow Leopards Using Next-Generation Sequencing

Authors: Johansson, O., Ullman, K., Lkhagvajav, P., Wiseman, M., Malmsten, J., Leijon, M.

Abstract: Snow leopards inhabit the cold, arid environments of the high mountains of South and Central Asia. These living conditions likely affect the abundance and composition of microbes with the capacity to infect these animals. It is important to investigate the microbes that snow leopards are exposed to detect infectious disease threats and define a baseline for future changes that may impact the health of this endangered felid. In this work, next-generation sequencing is used to investigate the fecal (and in a few cases serum) virome of seven snow leopards from the Tost Mountains of Mongolia. The viral species to which the greatest number of sequences reads showed high similarity was rotavirus. Excluding one animal with overall very few sequence reads, four of six animals (67%) displayed evidence of rotavirus infection. A serum sample of a male and a rectal swab of a female snow leopard produced sequence reads identical or closely similar to felid herpesvirus 1, providing the first evidence that this virus infects snow leopards. In addition, the rectal swab from the same female also displayed sequence reads most similar to feline papillomavirus 2, which is the first evidence for this virus infecting snow leopards. The rectal swabs from all animals also showed evidence for the presence of small circular DNA viruses, predominantly Circular Rep-Encoding Single-Stranded (CRESS) DNA viruses and in one case feline anellovirus. Several of the viruses implicated in the present study could affect the health of snow leopards. In animals which are under environmental stress, for example, young dispersing individuals and lactating females, health issues may be exacerbated by latent virus infections.

We wish to inform you that our Module 2 – SLN Training Initiative – Prey
Surveys is now available as an online toolkit for our members.

About this course:
Asia’s mountain ungulates– also known as the Mountain Monarchs of high
Asia- play an important role in maintaining ecosystems by influencing
vegetation structure and nutrient cycling. These include Argali (Ovis
ammon), Blue Sheep (Pseudois nayaur), Asiatic Ibex (Capra sibirica),
Urial (Ovis orientalis) and Markhor (Capra falconeri). However, owing to
their remote mountainous habitats and associated challenges in sampling,
there is a lack of information regarding their abundance, population
trends and ecology. There is a need for more information about the
population status of these ungulates, which carries special significance
in the protection of the snow leopard across its range.

Our Module 2 aims to equip participants with the knowledge and tools to
plan and carry out robust mountain ungulate surveys using the
Double-observer Method. We dive into understanding the fascinating
ecology of these species based on the latest research. The module is
divided into 4 parts and covers key concepts from planning surveys,
conducting them, analysing data, and using outcomes for conservation
action, publication and/or policy. Alongside we will have fascinating
talks by subject experts, sharing their experiences and outputs. This is
critical as conservation status assessment of any species requires
rigorous monitoring of their abundances, which done over time, can
provide knowledge of population trends.

This course was conducted live through on-line sessions with Snow
Leopard Network participants in August 2020. The training took place
over 4 sessions (each 2 hours) corresponding to key learnings necessary
for designing and carrying out double observer surveys to assess
ungulate abundance and density. The recordings from this live training
are now available below. Do follow the outlined structure of the course
as each session builds on each other. In total the course consists of 8
hours of video presentation and discussion.

This module has been co-created by a team of researchers and
practitioners from across the snow leopard range, including India,
Pakistan, Mongolia and China: Dr. Hussain Ali, Purevjav (Puji)
Lkhagvajav, Chagsadulam (Chagsaa) Odonjavkhlan, Dr. Lingyun Xiao and
Munib Khanyari. Together the module co-creators have worked to study and
protect mountain ungulates including Argali, Asiatic Ibex, Blue Sheep,
Markhor and Urial across India, Pakistan, Mongolia, China and
Kyrgyzstan.

The live training sessions were led by Munib Khanyari with the support
of a number of guest speakers (Chagsadulam (Chagsaa) Odonjavkhlan,
Abhirup Khara and Dr. Yash Veer Bhatnagar). Munib is currently a PhD
Candidate at the University of Bristol and Oxford University in the UK.
He works on understanding factors that affect mountain ungulate
populations in Central and South Asia.
