Interrupting pathogen transmission between species is a priority strategy to mitigate zoonotic threats. However, avoiding counterproductive interventions requires knowing animal reservoirs of infection and the dynamics of transmission within them, neither of which are easily ascertained from the cross-sectional surveys that now dominate investigations into newly discovered viruses. We used biobanked sera and metagenomic data to reconstruct the transmission of recently discovered bat-associated influenza virus (BIV; H18N11) over 12 years in three zones of Peru. Mechanistic models fit under a Bayesian framework, which enabled joint inference from serological and molecular data, showed that common vampire bats maintain BIV independently of the now assumed fruit bat reservoir through immune waning and seasonal transmission pulses. A large-scale vampire bat cull targeting rabies incidentally halved BIV transmission, confirming vampire bats as maintenance hosts. Our results show how combining field studies, perturbation responses, and multi-data-type models can elucidate pathogen dynamics in nature and reveal pathogen-dependent effects of interventions.

Even though bats are the second most speciose group of mammals, neuroanatomical studies of their hippocampus are rare, particularly of small echolocating bats. Here, we provide a qualitative and quantitative neuroanatomical analysis of the hippocampus of small echolocating bats (Phyllostomidae and Vespertilionidae). Calcium-binding proteins revealed species- and family-specific patterns for calbindin and calretinin.

Habitat fragmentation can have negative impacts on wildlife including increased risk of infectious disease. To assess spatiotemporal changes in pathogen dynamics in vampire bats () in response to habitat fragmentation, we used general linear mixed models to investigate the influence of site, year, and tree cover on the prevalence of and hemotropic (hemoplasma) in bats in one large and one small forest fragment in northern Belize across seven years. was marginally more prevalent in later years, while year and site differences in hemoplasma infections were driven by a peak in prevalence in the third year of the study in the small fragment.

Dubois, 1983 is a digenean trematode originally described from the intestine of the woolly false vampire bat, (Peters, 1856), in the northwestern Peruvian Amazon. Decades later, it was also reported from the fringe-lipped bat, (Spix, 1823), in Ecuador. During a helminthological survey of phyllostomid bats at the Kawsay Biological Station in Madre de Dios, southeastern Peruvian Amazonia, specimens of Railliet, 1919 were recovered from the intestine of Morphological comparisons with the holotype confirmed these specimens as conspecific with Phylogenetic inference supported the morphological identification, recovering the Peruvian isolate with an isolate from another South American region within the same clade, with strong support (ML = 90; BI = 0.

Vampire bats (Desmodus rotundus) possess an oral venom system consisting of submandibular glands that produce bioactive compounds, delivered to prey via their sharp incisors. The venom has long been recognized for its anticoagulant and proteolytic properties, which disrupt blood clot formation and interfere with the coagulation cascade. A peptide with high structural similarity to human calcitonin gene-related peptide (hCGRP), a potent vasodilator, was recently discovered in the venom of Desmodus rotundus.
