Background: Sparganosis is a zoonotic disease caused by Plerocercoid larvae (spargana) of the genus . We aimed to provide molecular evidence for the infection of amphibians with sp. in the inside and outside of Horton Plains National Park (HPNP), Sri Lanka.
Methods: The prevalence of sparganum infection in wild frogs () was investigated in the inside and outside of HPNP from June 2019 to April 2021.A total of 1,434 Amphibians samples were surveyed to examine the spargana infection from the study site. To identify the species identity of the collected spargana, a portion of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene and nuclear 18S rRNA gene were amplified, sequenced, and analyzed.
Results: A total of 539 infected amphibians ( and ) samples were examined to survey from the study area. Spargana were detected in all dissected specimens belonging to the species that were genetically confirmed using the evolutionary conserved nuclear 18S rRNA gene and then compared to the GenBank deposit, indicating that is the primary causal agent of sparganosis both inside and outside the HPNP.
Conclusion: Our finding is the first genetically confirmed record of in amphibians in South Asia. However, further studies are needed to investigate the prevalence of sparagna infection in amphibians all over the island.

Pelophylax nigromaculata, common traditional Chinese medicinal material used for several hundreds of years, is one of the most widely distributed amphibians in China. In this study, a novel Ranatuerin-2 family antimicrobial peptide, Rana-2PN, was identified and characterized from its skin, and its structural characteristics and functional activities were studied extensively. First, Rana-2PN exhibited a broad spectrum of antimicrobial activity, displaying minimum inhibitory concentration (MIC) values ranging from 12.

Background/objective: There is little data on infections of the genus Cosmocercoides Wilkie, 1930 in toad populations in Iran. Hence, the present study aims to report the first morphological description of the new genus Cosmocercoides Wilkie, 1930 (Ascaridida: Cosmocercidae) in Iranian toads (Bufotes surdus).
Methods: During the helminthological survey from October 2023 to December 2023, 10 specimens of Bufotes surdus were collected.
Immunomodulatory peptides: new therapeutic horizons for emerging and re-emerging infectious diseases.

The emergence and re-emergence of multi-drug-resistant (MDR) infectious diseases have once again posed a significant global health challenge, largely attributed to the development of bacterial resistance to conventional anti-microbial treatments. To mitigate the risk of drug resistance globally, both antibiotics and immunotherapy are essential. Antimicrobial peptides (AMPs), also referred to as host defense peptides (HDPs), present a promising therapeutic alternative for treating drug-resistant infections due to their various mechanisms of action, which encompass antimicrobial and immunomodulatory effects.

Background: Acanthocephalans (thorny headed worms) of the genus Pseudoacanthocephalus mainly parasitize amphibians and reptiles across the globe. Some species of the genus Pseudoacanthocephalus also can accidentally infect human and cause human acanthocephaliasis. Current knowledge of the species composition of the genus Pseudoacanthocephalus from amphibians and reptiles in China is incomplete.
