Abstract: The present invention is directed towards methods, compositions and kits for testing SARS-CO-V2 virus in a sample. The methods determine the presence of a viral 3CL protease by contacting the sample with a peptide compound capable of being cleaved by the protease to form peptide compound fragments. Detection of a peptide compound fragment confirms the presence of the virus.

Abstract: In alternative embodiments, provided are methods for treating, ameliorating, decreasing the chances of having any adverse effects from, decreasing the severity of adverse effects from, or preventing an infection by administration of an antibiotic and/or an anti-viral drugs and a vaccine directed to a causative agent of the infection and/or an attenuated and/or a live, viable or infectious causative agent of the infection. In alternative embodiments, the infection is bacterial or viral. In alternative embodiments, the viral infection is a coronavirus infection such a Covid-19 infection. In alternative embodiments, methods as provide herein prevent or decrease the prevalence or severity of “vaccine breakthrough infections” after vaccination, where external mutants of COVID-19 infect patients in spite of the fact that they have undergone immunization, for example, to prevent a mutant or variant COVID-19 infection.

Abstract: One aspect of the present invention is directed to a method for detecting acute Borna Disease Virus (BDV) infections. According to the invention, the presence of heterodimers of p24 BDV phosphoprotein and p40 BDV nucleoprotein in a sample is determined by means of antibodies of both proteins using a sandwich ELISA. The invention also relates to a diagnostic kit for a sandwich ELISA for detecting mute BDV infections. Said kit uses a antibody of p24 BDV phosphoprotein and a second primary antibody of p40 BDV nucleoprotein, at least one reporter-molecule-labelled secondary antibody, means for immobilising a primary antibody on a surface, and instructions for carrying out the method according to the invention. The invention also relates to the combination of the method according to the invention and the new diagnostic kit with known methods for detecting circulating immune complexes (CIC) and antibodies.
