Search for: [Abstract = "oral cavity was assessed using the Oral Health Assessment Tool \(OHAT\) \[31\]. Six oral habitats were sampled\: buccal \(marked A\) and soft palate \(B\) mucosa, the tongue \(site marked C\), palatal \(Da\) and buccal \(Db\) dental surface, and the gingival pocket \(E\). Material from sites A, B and C was collected using ESwab™, from site D with Tooth Cleanic KerrHawe, and from site E with PerioPaper Strips. The samples were cultured with the use of traditional methods for aerobic and anaerobic bacteria and funghi. After isolation, the microorganisms were identified by MALDI\-TOF MS \(Vitek MS Home bioMérieux\). Results summary and conclusions Analysis of material from COVID\-19 patients revealed significant qualitative and quantitative dysbiosis in the oral microbiota. The dysbiosis involved decreased species diversity and abundance of pathogenic strains of Acinetobacter baumannii, Enterococcus faecalis, Escherichia coli and Klebsiella pneumoniae, comprising noteworthy findings among this group of patients. Moderate or severe disorders of oral health \(BOAS score 10\-14\) was correlated with the increased level of dysbiosis. The median CFU counts of all bacterial strains in buccal dental surface was 4.0E\+5 \(1.0E\+5 –1.4E\+6\) and in gingival crevicular fluid 2.0E\+5 \(4.0E\+4 – 8.0E\+5\). The highest median CFU counts were observed for Enterococcus spp. and Lactobacillus spp. Durin"]
