6/ This work reinforces the value of One Health surveillance looking beyond vertebrate hosts alone and includes the arthropods associated with them. Very grateful to all co-authors and collaborators across virology, entomology, field ecology, metagenomics, and virus discovery.

5/ Using metagenomic sequencing, phylogenetics, virus isolation, and cell-culture experiments, we found that SCCV can replicate in mammalian cell lines. SCCV was detected in 18.4% of examined bat bugs, highlighting how much remains unknown at the bat–ectoparasite–virus interface.

4/ This connection is interesting because it links Cambodian bat-associated ectoparasites to a broader group of bat-associated coltivirus-like viruses detected across very different geographic regions.

3/ SCCV is most closely related to Tai Forest reovirus, a coltivirus-related virus originally isolated from the blood of free-tailed bats captured in Côte d’Ivoire in 2006.

2/ We identified a novel coltivirus, provisionally named Stricticimex coltivirus (SCCV), in a newly described bat bug species associated with cave-dwelling wrinkle-lipped free-tailed bats (Mops plicatus) in Cambodia.

First human #H5N1 case of 2026 in #Cambodia: a 30-year-old man from Kampot province. Sequencing, virus isolation & animal investigations ongoing. Dead chicken at home before onset. Patient has since recovered. 🦠💉😷🐓🥼🔬🧪 Sequencing, contact tracing, and poultry investigations ongoing.

In May 2025, The Telegraph joined our field mission on virus surveillance work in #Cambodia, where we used novel, non-invasive techniques like air sampling in live bird markets and bat caves, paired with field-deployable tools, to detect #emergingviruses at the source.

Cambodia has confirmed its 9th and 10th human cases of H5N1 bird flu this year. 6 of these cases occurred in June alone. Sadly, 6 people have died in 2025. 🧪🧬🦠🔬🥼😷🐓💉

Our findings emphasize the need for interdisciplinary approaches to zoonotic disease surveillance, integrating virology, ecology, and public health. SCCV adds to the growing list of coltiviruses with potential public health implications. #OneHealth #GlobalHealth #Virology

Could bat ectoparasites serve as a vector and/or reservoir of zoonotic viruses? #OneHealth With increasing human-wildlife contact in biodiverse regions, understanding viral diversity in ectoparasites like bat bugs is crucial for preventing spillovers. #EmergingViruses #EID

SCCV is closely related to Tai Forest Reovirus (TFRV), previously found in African bats found in 18.4% of bat bugs collected from cave-dwelling bats. SCCV was successfully isolated in several mammalian cell lines, showing potential to infect vertebrate hosts.
