Genomic surveillance of Sars-CoV-2 in the Andean Community (2020–2024): Integrating regional sequencing efforts from Colombia, Ecuador, Peru, and Bolivia through “Oras-Conhu” program
Introduction: The COVID-19 pandemic has deeply affected Latin American countries, with countless COVID-19 cases and deaths. In countries like Peru, Colombia, Ecuador and Bolivia there was a collapse of the public health system, and the lack of testing capacity did not allow to control the spread of SARS-CoV-2 during the first year of the COVID-19 pandemic. After these dramatic beginnings, regional efforts focused on improving testing capacity and…
Rapid spread of the emerging cosmopolitan genotype of dengue virus serotype 2, and expansion of dengue virus serotype 1 genotype V in Peru
Our findings suggest the urgent need to strengthen epidemiological and genomic surveillance systems to understand and control the spread of circulating DENV genotypes in Peru. This will allow a more rapid response, as well as the monitoring of its potential dissemination to other countries in the Americas
Neutralización del coronavirus Sars-CoV-2 por suero hiperinmune de llama (Lama glama) en cultivo de células Vero
The findings suggest that hyperimmune llama serum could constitute a source of therapeutic antibodies against SARS-CoV-2 infections (lineage B.1.1), and should be studied in further research
Validación y evaluación de una prueba de RT-PCR en tiempo real in house para la detección de Sars-CoV-2 usando un gen específico RdRp y control endógeno GAPDH
The present work validated and evaluated a duplex real-time RT-PCR using specific primers and probes for genes RdRp from SARS-CoV-2 and GAPDH from humans; the latter was used as an endogenous control in all reactions. We evaluated the specificity, the sensitivity, the robustness, the reproducibility, the repeatability, the comparability, and the limit of detection. The predictive positive and negative values (PPV and PNV, respectively) and all th…
Identificación de especies de Leishmania en pacientes derivados al Instituto Nacional de Salud del Perú
In Peru, leishmaniasis is a metaxenic disease that represents a serious public health problem, due to its wide distribution and the number of people in danger of contracting the disease, being the vulnerable population mainly those with low economic resources. The study was conducted from patients who were derived to Peru's National Institute of Health between 2006 and 2011 so that the specialized diagnosis could be carried out. The identificatio…
Neutralización de la actividad letal del veneno de serpiente Bothrops atrox por suero hiperinmune de llama (lama glama)
The hyperimmune llama serum is able to neutralize the lethality of the Bothrops atrox venom from Peru in laboratory mice
Especies rickettsiales en casos humanos con síndrome febril agudo inespecífico en Perú
With the objective of molecularly characterizing rickettsial isolates from humans with non-specific acute febrile syndrome, a cross-sectional descriptive study was conducted, with isolates propagated in Vero ATCC cellular cultures and alternative lines, verifying the viability by means of Indirect Immunofluorescence. Prior to DNA extraction, the gltA gene was amplified by means of conventional PCR, and its sequence was analyzed. Twelve isolates w…
Perfil epidemiológico y molecular de Rickettsiosis en localidades de frontera peruana
Serological and molecular evidence confirms the circulation of Rickettsia in the border locations studied, with predisposing epidemiological factors. Tests confirm the presence of two species, Rickettsia felis and Candidatus Rickettsia asemboensis, which represent a potential threat to the health of the inhabitants
Prueba molecular genotype® MTBDRplus, una alternativa para la detección rápida de tuberculosis multidrogorresistente
The Genotype®MTBDRplus molecular test is a method that allows identification of the most frequent mutations associated with resistance to major first-line antituberculosis drugs, Isoniazid (INH) and Rifampicin (RfP). The aim of this study was to evaluate the performance of the molecular test with culture and smear- positive sputum samples. We evaluated 95 cultures and 100 sputum samples with resistance profiles previously determined by the refere…
Leishmaniosis cutanea: Manifestación clínica inusual
Clinical manifestations of leishmaniasis are diverse and related to the infecting species, its relationship with the environment and the host immune response. A case of late Andean cutaneous leishmaniasis with extensive manifestation is presented. The case was confirmed through microbiological and immunological studies; identification was performed by cytochrome b gene sequencing and the species was determined as Leishmania (Leishmania) amazonens…
