Abstract A metagenomic analysis was performed by high-throughput sequencing (HTS) to identify viruses infecting a wild weed collected in Seles (Angola), which exhibited clear yellowing symptoms. The analysis led to the discovery of a putatively novel carlavirus, tentatively named ‘Seles weed carlavirus’. The complete genome sequence, consisting of 8,597 nucleotides, poly-A tail excluded, exhibite…

Abstract Spiraea plants showing symptoms of virus infection were investigated using high-throughput sequencing which resulted in the identification of two novel viruses: an emaravirus named Spiraea chlorotic leaf spot distortion virus (SCLSDV), and an alphacytorhabdovirus named Spiraea alphacytorhabdovirus 1 (SpCRV-1). The complete genome of SCLSDV comprises four RNA segments, each encoding a dis…

Abstract Enterovirus D68 (EV-D68) is a re-emerging respiratory pathogen that is increasingly associated with severe respiratory disease and occasional neurological complications, yet its circulation in Portugal remains poorly documented. In the present study, we investigated the presence of EV-D68 in respiratory samples collected in southern Portugal (Algarve region) from October 2024 to February…

Feline stool-associated circular DNA virus (FeSCV), was identified in Japan (2018) and China (2021) but has not yet been detected outside Asia. In this study, 137 fecal or rectal swab samples from 83 cats were screened for circoviruses and FeSCV, with detection of two putative novel Cyclovirus species and 19.3% (16/83) of FeSCV. A higher incidence of FeSCV in kittens and young adults, and FCoV-po…

A novel lytic bacteriophage, Ecolivirus Myo‑P293 (P293), targeting avian pathogenic Escherichia coli (APEC), was isolated from duck farm sewage in Jiangsu, China. P293 formed clear plaques approximately 2 mm in diameter and displayed the characteristic morphology of Myoviridae family, with an icosahedral head (~ 70 nm) and a contractile tail (~ 100 nm), as observed under transmission electron mic…
