bat sars-like coronavirus wiv1 bat sars-like coronavirus wiv1 bat sars-like coronavirus wiv1 (bat sl-cov-wiv1), also sometimes called sars-like coronavirus wiv1, is a strain of severe acute respiratory syndrome–related coronavirus (sarsr-cov) isolated from chinese rufous horseshoe bats in 2013 (rhinolophus sinicus). like all coronaviruses, virions consist of single-stranded positive-sense rna enclosed within an envelope. bat sars-like coronavirus wiv1 virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: pisuviricota class: pisoniviricetes order: nidovirales family: coronaviridae genus: betacoronavirus subgenus: sarbecovirus species: severe acute respiratory syndrome–related coronavirus strain: bat sars-like coronavirus wiv1 synonyms sars-like coronavirus wiv1 bat sl-cov-wiv1 zoonosis the discovery confirms that bats are the natural reservoir of sars-cov. phylogenetic analysis shows the possibility of direct transmission of sars from bats to humans without the intermediary chinese civets, as previously believed. phylogenetic a phylogenetic tree based on whole-genome sequences of sars-cov-1 and related coronaviruses is: sars‑cov‑1 related coronavirus 16bo133, 86.3% to sars-cov-1, rhinolophus ferrumequinum, north jeolla, south korea jtmc15, 86.4% to sars-cov-1, rhinolophus ferrumequinum, tonghua, jilin bat sars cov rf1, 87.8% to sars-cov-1, rhinolophus ferrumequinum, yichang, hubei btcov hku3, 87.9% to sars-cov-1, rhinolophus sinicus, hong kong and guangdong lyra11, 90.9% to sars-cov-1, rhinolophus affinis, baoshan, yunnan bat sars-cov/rp3, 92.6% to sars-cov-1, rhinolophus pearsoni, nanning, guangxi bat sl-cov ynlf_31c, 93.5% to sars-cov-1, rhinolophus ferrumequinum, lufeng, yunnan bat sl-cov ynlf_34c, 93.5% to sars-cov-1, rhinolophus ferrumequinum, lufeng, yunnan shc014-cov, 95.4% to sars-cov-1, rhinolophus sinicus, kunming, yunnan wiv1, 95.6% to sars-cov-1, rhinolophus sinicus, kunming, yunnan wiv16, 96.0% to sars-cov-1, rhinolophus sinicus kunming, yunnan civet sars-cov, 99.8% to sars-cov-1, paguma larvata, market in guangdong, china sars-cov-1 sars-cov-2, 79% to sars-cov-1
