The metagenome of patients infected with SARS-Cov2 [1] has shown Prevotella to be a key player in immune response [2] in one Chinese study [3], just starting in another [4] and a host of other opportunistic pathogens in a study from San Diego county [5]. The metagenome can also be queried to find host response genes [5], as was done in monkey cells infected with SARS-Cov2 [6]Nanopore sequencing data from a familial cluster in ShenzhenThe patients were tested for 4 bacterial species - Bordetella pertussis, Bordetella parapertussis, Chlamydophila pneumoniae, and Mycoplasma pneumoniae. The sequencing data (Accid:SRR10948474, Nanopore) from five patients in a family cluster from Shenzhen who presented with unexplained pneumonia after returning from Wuhan (Table 1) shows a wide range of bacterial species - Lautropia, Cutibacterium, Haemophilus being most abundant. The presence of Campylobacter explains diarrhea seen in the patient [7,8]. Also, their tests should have detected Mycoplasma, since it is there in the data.Significant bacterial load with some bacterial species predominatingThe bacterial reads are about 20% (95K out of 500K reads). The viral load is also significant here (70K reads) [2]. They are in SI.familial/allsequences.fa. The number of bacterial species (with at least two reads) is 876 (SI.familial/list.allbacteria.txt). Thus, it is important to consider secondary infection, a possible reason why azithromycin (in addition to hydroxychloroquine) has given good initial results in a clinical trial [9].
