Few studies have analyzed the role of the lung microbiome in the diagnosis of pulmonary coinfection in ventilated ICU COVID-19 patients. We characterized the lung microbiota in COVID-19 patients with severe pneumonia on invasive mechanical ventilation using full-length 16S rRNA gene sequencing and established its relationship with coinfections, mortality, and the need for mechanical ventilation for more than 7 days. This study included 67 COVID-19 ICU patients.

Article Synopsis
  • Mayaro Fever (MF) is caused by the Mayaro virus and has been reported in outbreaks in Latin America, particularly in Leticia, Colombia, where a fever surveillance study was conducted.
  • In a sample of 1,460 patients, most cases were linked to dengue and malaria, but 71.4% were unexplained until metagenomic sequencing detected MAYV in two patients with MF symptoms.
  • This research marks the first identification of MAYV in Colombia, indicating a need for more studies and improved surveillance to monitor its spread in the region.

Objective: To describe bacterial microbiota in the biosolids generated in one of the largest wastewater treatment plants of Colombia.

Materials And Methods: Using NGS technology, 16S rRNA Gene Amplicon libraries were amplified and sequenced. The Roche 454 FLX Titanium platform was used, while the V1-V3 and V6-V9 hypervariable regions were amplified and analyzed independently.
