An On-Line Cross-Sectional Questionnaire to Assess Knowledge of COVID-19 Pandemic among Citizens Tested for the SARS-CoV-2 Virus in Quito and Ibarra, Ecuador.

Several public health measures have been implemented to contain the SARS-CoV-2 outbreak. The adherence to control measures is known to be influenced by people's knowledge, attitudes and practices with regard to the disease. This study aimed at assessing COVID-19 knowledge in individuals who were tested for the virus.

Oomycete metabarcoding reveals the presence of spp. in phytotelmata.

The oomycete genus , which includes the mosquito biocontrol agent , is composed of animal pathogens, yet is phylogenetically closely related to the well characterized plant pathogens and spp. These phylogenetic affinities were further supported by the identification of canonical oomycete effectors in the transcriptome. In this study, culture-independent, metabarcoding analyses aimed at detecting in bromeliad phytotelmata (a proven mosquito breeding ground) microbiomes were performed.

Multidrug-resistant Escherichia coli isolated from canine faeces in a public park in Quito, Ecuador.

Objectives: This study focused on estimating the prevalence of extended-spectrum β-lactamases (ESBLs), plasmid-mediated AmpC β-lactamases, carbapenemases and MCR-1-producing Escherichia coli in canine faeces from a public park in Quito, Ecuador.

Methods: Phenotypic and genotypic characterisation of E. coli isolated from 50 canine faecal samples recovered from a city park in Quito was performed.
