Natural Infections with Human Respiratory Syncytial Viruses in Non-Primate Animals, Pangolins

BACKGROUND: Respiratory viruses circulate everywhere. Problem of pandemic respiratory virus SARS-CoV-2 is especially relevant. The understanding of level of circulation of different viruses can help in developing a strategy of respiratory viruses combat. AIM: To compare circulation of respiratory viruses during different seasons. MATERIALS AND METHODS: PCR-diagnostic. RESULTS: The most common viruses before the pandemic were influenza and respiratory syncytial viruses. COVID-19 pandemic season 2020/2021 had significant difference from previous epidemic seasons. Influenza viruses have largely disappeared, but the circulation of seasonal coronavirus and metapneumovirus has increased. The circulation of rhinovirus remained at the same level. CONCLUSIONS: The emergence of pandemic SARS-CoV-2 virus had a significant impact on some respiratory viruses circulation, such as influenza or respiratory syncytial viruses.

Syncytial Virus

In reverse transcription-polymerase chain reactions (RT-PCR) and DNA hybridizations using primers and an oligonucleotide probe to the fusion (F) protein mRNA of bovine respiratory syncytial virus (BRSV), all the BRSV isolates and a goat isolate could be distinguished from prototype isolates of human respiratory syncytial viruses (HRSV) and ovine (sheep and bighorn sheep) respiratory syncytial viruses (RSV). However, RT-PCR amplifications with primers to sequences of the HRSV F protein mRNA resulted in amplified products of ≍ 243 bp if mRNA templates of subgroup A HRSV strains were present and slightly larger amplified products with subgroup B HRSV strains. No amplified products were observed in HRSV-primed RT-PCR with BRSV or goat or ovine RSV mRNA templates. Although the ovine RSV isolates were antigenically cross-reactive with the goat RSV, HRSV and BRSV isolates, they were not amplified with either HRSV- or BRSV-specific primers in RT-PCR. These results confirm previous immunological comparisons suggesting that some ovine RSV isolates should be considered as distinct respiratory syncytial viruses.
