Screening for SARS-CoV-2 in conjunction with bacterial co-infections was not prioritized during the COVID-19 pandemic, but some investigations were carried out and have reported an association of Cpn and Mycoplasma pneumoniae co-infection along with or following a SARS-CoV-2 infection (Oliva et al., 2020; De Francesco et al., 2021). The gene discussed is CPN1; the disease is coinfection.
