The animals were monitored daily for the clinical signs and body weight. Throat swab, nasal wash, and organ samples (lungs, nasal turbinate, trachea) were collected and screened using SARS-CoV-2-specific RT-qPCR. Histopathologic evaluation of the lung samples was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The hamsters infected with the Kappa variant demonstrated increased body weight loss compared to the B.1 lineage isolate. The highest viral RNA load was observed in the nasal turbinate and lung specimens of animals infected with both variants. A significantly higher sgRNA load was observed in the nasal swabs (7 DPI), trachea (3 DPI), and lungs (3 DPI) of hamsters infected with the Kappa variant. Neutralizing antibody response generated in the B.1 lineage-infected hamster sera were comparable against both B.1 and Kappa variant in contrast to Kappa variant-infected hamsters, which showed lower titers against B.1 lineage isolate. Gross and microscopic evaluation of the lung specimens showed severe lung lesions in hamsters infected with Kappa variant compared to B.1.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The study demonstrates pathogenicity of Kappa variant in hamsters evident with reduced body weight, high viral RNA load in lungs, and pronounced lung lesions.
