Detection and isolation of IDV in cattle among provinces of China, 2022–2023. (A) The numbers of IDV-positive nasal swab samples from cattle in each province of China, 2022–2023. The colours indicate positive rates of IDV in cattle among provinces according to the legend located at the left bottom of the map. The numbers of IDV-positive nasal swab samples are given in blue colour (bold font), and the numbers of total nasal swab samples collected in cattle in individual provinces are given in yellow colour (bold font). The overall IDV RNA positive rate in cattle in China according to this study is indicated in the top of the map. (B) IDV RNA positive rates and samples in cattle in individual provinces tested. (C) Negative-staining electron microscopy showing an enveloped spherical IDV particle ((Bar = 200 nm)). (D) Thin-section electron microscopy displaying budding and release of IDV virions from the plasma membrane of infected cells (Bar = 1 µm).
