AMR is a growing One Health concern, and understanding the role of wildlife, especially species like flying foxes, in spreading resistant bacteria is crucial for the health of humans, animals, and the environment.

Touseef’s research focuses on an important, yet often overlooked, driver of antimicrobial resistance (AMR) – environmental temperature and relative humidity. These factors indirectly affect wildlife behaviors, which can increase the risk of encountering antimicrobial residues and pathogenic Extended Spectrum β-Lactamase (ESBL) producing E. coli.  

Proposed Environmental Antimicrobial Resistance Propagation Pathways by Pteropus medius

Research Key Highlights:

  • Resistance was found against last resort Reserve class antibiotics such as aztreonam (16%) and imipenem (2%).
  • 46% of isolates showed multi-drug resistance.
  • 37% were ESBL producers, with the blaTEM gene present in over 90% of isolates, particularly in winter samples.
  • Environmental and land use factors like human settlement and water bodies were found to influence the isolation of resistant genes.

This research sheds light on the complex relationship between environmental factors, land use, and AMR propagation via P. medius, emphasizing the need for an integrated One Health approach to combat AMR.

Our Malaysian bat project team (Isham, Hendra and Rahul) represented the Kingston lab at the 109th annual meeting of the Ecological Society of America in Long Beach, California from August 4 to 8, 2024. Isham’s brilliant presentation showed how the expected environmental filtering and niche packing for insectivorous bats were significant in continuous forests but not in the fragmented patches, highlighting the role of stochastic processes in fragmented landscapes. Hendra gave a data-rich yet engrossing talk on optimizing methods for metabarcoding insects from bulk samples captured using light traps. He demonstrated that four subsamples of 100μL each recovered 90% Operational Taxonomic Units (OTU; equivalent to species) from these homogenized samples of potential bat prey. Rahul’s presentation carried Hendra’s research forward by identifying forest characteristics that influenced insect alpha diversity. Additionally, his work showed that dietary diversity of insectivorous bats was not linked to prey diversity and there was limited overlap between OTUs recovered from light traps and those from bat feces.   

In addition to the super-insightful plenary sessions, our team had a great time dashing from room to room catching up on much cool science being presented simultaneously! With over 3500 attendees, plenty of exhibitions and dedicated career counselling sessions, they benefitted immensely in terms of networking opportunities.

Our second field season in Nigeria wrapped up this summer after an intensive seven months of bat surveys and sampling (November 2023 – June 2024). Ben led a field team of 15 to survey 17 caves across two sites in southern Nigeria sampling 1266 bats. This work is part of our larger collaborative effort to understand how human disturbance affects the complex relationships between bats, their environment, and their host viruses – critical knowledge for predicting and preventing viral spillover events. While focusing on the ever-cute Egyptian fruit bat (Rousettus aegyptiacus), the team also sampled other 17 bat species including the beautiful Otomops martiensseni, a new country record for Nigeria!

Perhaps most importantly, this field season significantly strengthened the local capacity for bat research in Nigeria. Tigga and Dr. Simon Anthony were there to train field team on biosafety, sampling techniques etc.

The field season came with its fair share of challenges—maintaining cold chains for sample preservation was no cakewalk, with liquid nitrogen sources a bone-rattling 10-hour drive away. Add that to the logistical hurdles of hauling a 15L liquid nitrogen-charged dry shipper up and down a steep mountain, requiring a grueling 9-hour hike each way. But the dedication of the field team, especially our Nigerian colleagues, made it all fun.

Ashraf was telling a bat story, keeping the audiences hanging on every word

At the 42nd annual Texas Society of Mammalogists meeting in February 2024, Ashraf presented a poster on how bat assemblages are responding to land-use change in Bangladesh. During his two-year adventure in the world of bats, he documented 16 bat species across 5 families and 4 feeding guilds, employing a combination of mist nets and harp traps. His research illustrates that bat species diversity is greater in forests compared to degraded land-use within the protected areas. In addition, Ashraf demonstrated that bat species composition varies across study sites, emphasizing that forested areas are home to specialist bat species, in contrast to degraded sites. Remarkably, Ashraf’s study pioneered the use of the harp trap as a successful method for capturing forest understory bats in Bangladesh, representing a substantial leap forward in the country’s bat research.

Just like in any other lab, it’s a time-honored tradition for Kingston’s lab members to attend the annual TTABSS. This year, four members showcased parts of their PhD dissertation work. Abby snagged the Best Oral Presentation in Ecology award! Hurray!

Abby in action presenting her award-winning talk!

Isham, Ashraf, and Touseef also did their part in keeping this tradition alive, presenting on community ecology in fragmented habitats, species responses to land-use change, and bat responses to heat stress.

Touseef and co-authors conducted a comparative analysis of abstracts presented at the 1st (2011) and 6th (2020) World One Health Congresses (WOHC) to examine the evolution and current state of One Health research, focusing on demographic, disciplinary scope, and geographical representation. 

Key findings include:

  • Disease Surveillance remained the most represented research category at both congresses, indicating a consistent priority within One Health research.
  • Environmental and Ecological Issues and Sustainable Food Systems were among the least represented categories, despite the growing global emphasis on sustainable development challenges.
  • A significant increase in Antimicrobial Resistance (AMR) research, from 1% of abstracts in 2011 to 13% in 2020, highlights evolving research priorities.
  • Authors from Very High Human Development index countries tended to focus on Public Policy, whereas those from Medium and Low Human Development countries prioritized Disease Surveillance, indicating potential regional differences in One Health research priorities.
  • International collaboration is instrumental in enhancing participation from countries with lower human development indexes, although discrepancies remain in the representation of global regions and the alignment between funding recipients and research subjects.

The Skypuppies Are in Peril – Why Does it Matter?

The plight of large fruit bats on paleotropical islands was flagged over half a century ago. Despite this, species of Pteropus, Acerodon, and related genera of Large Old World Fruit Bats (herein, LOWFB) remain among the most endangered bat groups globally. Naturally, Tigga stepped up collaborating with esteemed bat scientists F.B. Vincent Florens and Christian E. Vincenot to explore this pressing issue. They utilized the IUCN Red List assessments and information from the literature to uncover why these bats are in trouble. No surprise here – habitat loss, hunting, climate change, and persecution (Let’s dub them the BIG FOUR) pose significant threats to the LOWFB. These poor bats are built differently, with biological and ecological attributes that make them even more vulnerable to these threats, accelerating their population decline.

So why should we care? Well, because they’re keystone species! Losing these skypuppies could set off a domino effect throughout native ecosystems. Check out the publication to discover more about the proposed conservation strategies aimed at halting the decline of these critical bats, especially in island habitats.
