Genomic surveillance of the Lambda SARS-CoV-2 variant in a global phylogenetic context.

The massive sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and global genomic surveillance strategies allowed the detection of many variants of concern and interest. The variant of interest Lambda (C.37), which originated in South America, has been the most prevalent in Peru and Chile, but its dispersion in other continents still remains unknown.

Genomic analysis reveals a rapid spread and predominance of lambda (C.37) SARS-COV-2 lineage in Peru despite circulation of variants of concern.

The pandemic generated by SARS-Cov-2 has caused a large number of cases and deaths in the world, but South America has been one of the continents that were most hard hit. The appearance of new variants causes concern because of the possibility that they may evade the protection generated by vaccination campaigns, their greater capacity to be transmitted, or their higher virulence. We analyzed the circulating variants in Peru after improving our Genomic Surveillance program.

Characterization of influenza A(H1N1)pdm09 isolates of Peru using HRM, a post PCR molecular biology method.

Influenza caused by A(H1N1)pdm09 is a public health issue with severe conditions in vulnerable populations leading to death. Therefore, it is of interest to characterize and monitor influenza A(H1N1)pdm09 genotypes using High Resolution Melting (HRM), a post PCR molecular biology method. We used HRM analysis (using RotorGene Q thermocycler) to characterize A(H1N1)pdm09 genotypes from several places of Peru.

Genetic identification of newborns in Peru: A pilot study.

Objective: To determine the feasibility of genetic identification in a group of newborns from a public hospital in Lima, Peru.

Material And Method: Descriptive cross-sectional study, carried out by the National Registry of Identification and Civil Status of Peru, on live newborns and their mothers, from the Carlos Lanfranco La Hoz Hospital (Puente Piedra, Lima) during January. 2015.

[Experiences in the epidemiological surveillance of foodborne pathogens by pulsed field gel electrophoresis (PFGE) in Peru].

Foodborne diseases and other enteric infections often occur as outbreaks and cause morbidity and mortality all over the world. In Perú, they represent a serious public health problem, and are caused by a great variety of infectious agents. For epidemiological research, a wide array of typification methods are used.
