T59 7843-8022 Sentence denotes The study, which was approved by the Landesamt für Gesundheit und Soziales in Berlin, Germany (permit # 0086/20), involved 24 female and male Chinese hamsters of 5–7 weeks of age.
T60 8023-8548 Sentence denotes Hamsters were randomly assigned to two groups (SARS‐CoV‐2‐infected, n = 12; mock‐infected, n = 12) Upon intranasal infection with 1x105 plaque‐forming units (pfu) of a human SARS‐CoV‐2 isolate, we observed clinical symptoms including transient but significant body weight loss and subtle drops in body temperatures at early time points after infection, a course of disease comparable to that in Syrian hamsters (Figure 1) (Chan et al., 2020; Imai et al., 2020; Kreye et al., 2020; Osterrieder et al., 2020; Sia et al., 2020).
T61 8549-8800 Sentence denotes Differences in body weights between infected and mock‐infected animals were significant at 1–3 and at 5 days post‐infection (dpi), infected hamsters did not reach pre‐infection body weights before 14 dpi when the experiment was terminated (Figure 1a).
T62 8801-9026 Sentence denotes However, the largest difference in mean body temperatures of infected compared to mock‐infected animals was only −0.6°C at 3 dpi (Figure 1b), suggesting that this parameter may not be useful to assess the status of infection.
T63 9027-9196 Sentence denotes We determined virus replication and virus spread by measuring RNA copy numbers in the lungs, bucco‐laryngeal swabs and whole blood samples of all hamsters (Figure 1c–e).
T64 9197-9574 Sentence denotes Figure 1 Body weight changes, body temperatures and virus loads of mock‐infected and SARS‐CoV‐2‐infected Chinese hamsters. (a) Individual relative body weights of mock‐infected (green) and SARS‐CoV‐2‐infected (red) hamsters over the course of 14 days after infection. p‐values indicate significant differences (Mann–Whitney U test). (b) Temperature changes (as means with SD).
T65 9575-9833 Sentence denotes Virus loads were determined from total RNA in (c) 2.5 mg homogenized right cranial lung lobes, in (d) bucco‐laryngeal swabs and (e) 2.5 µl of whole blood samples by RT‐qPCR In addition, we determined viral titres in the lungs of infected animals (Figure S1).
T66 9834-10026 Sentence denotes Our assays confirmed high RNA copy numbers and corresponding viral titres at early time points after infection followed by a rapid but incomplete clearance of the virus infection until 14 dpi.
T67 10027-10266 Sentence denotes With titres of up to 5 × 107 pfu per 50 mg lung tissue and viral RNA copies in the range of up to 1 × 107 per 2.5 mg lung tissue at early time points after infection, we concluded that Chinese hamsters are highly susceptible to SARS‐CoV‐2.
T68 10267-10482 Sentence denotes On the other hand, virus loads in blood samples were below 1 × 102 RNA copies per 2.5 µl of whole blood (15.6 ± 29.8 SD) at all time points, indicating lack of significant viremia and systemic infection (Figure 1e).
T69 10483-10589 Sentence denotes These observations match findings from other animal models for emerging coronaviruses (Yuan et al., 2020).
T70 10590-10851 Sentence denotes Lung histopathology revealed tissue damage and inflammation principally similar to what has been described in Syrian hamsters (Figure 2) (Chan et al., 2020; Gruber et al., 2020; Imai et al., 2020; Kreye et al., 2020; Osterrieder et al., 2020; Sia et al., 2020).
T71 10852-10980 Sentence denotes However, the course of bronchitis and pneumonia was in general milder than in Syrian hamsters, and pneumonia was more prolonged.
T72 10981-11179 Sentence denotes Specifically, prominent acute alveolar damage was present until 14 dpi with persistence of viral RNA (Figures 1c, 2g‐i and S2), indicating overall slower recovery than described for Syrian hamsters.
T73 11180-11361 Sentence denotes Similarly, viral RNA was localized by in situ hybridization to bronchial epithelial cells, alveolar epithelial cells type‐I and type‐II and alveolar macrophages (Figure S2, arrows).
T74 11362-11459 Sentence denotes Figure 2 Histopathological assessment of mock‐infected and SARS‐CoV‐2‐infected Chinese hamsters.
T75 11460-11673 Sentence denotes Histopathology of haematoxylin–eosin‐stained lung sections from SARS‐CoV‐2‐infected Chinese hamsters revealed suppurative bronchitis (a, b; arrow: neutrophils) and necrosuppurative pneumonia (c, d) at 2 and 3 dpi.
T76 11674-11780 Sentence denotes At 5 dpi (e, f), additional hyperplasia of alveolar epithelial cells (AEC)‐type II was salient (f, arrow).
T77 11781-11892 Sentence denotes Tissue damage, cell influx and hyperplasia of AEC‐II (h, arrow) were milder but still present at 14 dpi (g, h).
T78 11893-12022 Sentence denotes Of note, acute alveolar damage (I, arrows) was multifocally distributed throughout the lungs across all time points investigated.
T79 12023-12090 Sentence denotes None of these lesions was detected in mock‐infected animals (j, k).
T80 12091-12096 Sentence denotes Bars:
T81 12097-12440 Sentence denotes 1 mm (a, c, e, g, j) or 50 µm (b, d, f, h, i, k) In agreement with the clinical course of disease, virological and histopathological results confirm that this animal model withstands the comparison with the Syrian hamster model with the advantage of a prolonged period of significantly reduced body weights following infection with SARS‐CoV‐2.
T82 12441-12648 Sentence denotes Moreover, the considerably smaller size of the Chinese hamster offers an important practical advantage when compared to the rather large Syrian hamster and allows husbandry in smaller cages and lager groups.
T83 12649-12939 Sentence denotes Additionally, the Chinese hamster genome, transcriptome and translatome are well characterized and a variety of molecular tools is available for this species as Chinese hamster ovary (CHO) cells are widely used in biopharmaceutical research and industry (Matasci et al., 2008; Walsh, 2018).
T84 12940-13192 Sentence denotes At the same time, the usefulness of any model depends on fundamental knowledge of species‐specific similarities to and differences from the human disease, as well as other confounding factors, including age and comorbidities (Metersky & Waterer, 2020).
T85 13193-13410 Sentence denotes Because of the heterogeneous disease phenotype in humans, there is a need for different SARS‐CoV‐2 animal models that allow evaluation of vaccines and antiviral therapies for different subsets of the human population.
T86 13411-13600 Sentence denotes Taken together, our results suggest the suitability of the Chinese hamster small animal model to study SARS‐CoV‐2 infections, with body weight losses as a robust clinical disease parameter.
T87 13601-13741 Sentence denotes As an established model for SARS‐CoV‐1 infection, the Chinese hamster may also allow comparison between experimental coronavirus infections.
T88 13742-13953 Sentence denotes Moreover, our findings highlight the possibility of comparing, in future studies, the effects of preventive as well as therapeutic measures to restrain infection and viral replication in different animal models.
