Background
Bacteria of the genus Borrelia are agents of disease in both domestic animals and humans and pose a significant public health risk. Borrelia species have complex transmission cycles, often using rodents as vertebrate reservoir hosts. These bacteria are classified into three well-defined monophyletic groups: Borrelia burgdorferi sensu lat...

Background
The genus Borrelia comprises pathogenic species of bacteria that pose a significant risk to public health. Borrelia spp. are emerging or reemerging infectious agents worldwide with complex transmission cycles, and many species use rodents as vertebrate reservoir hosts. Spirochetes morphologically compatible with Borrelia have been recurr...
In Colombia, tropical febrile illnesses represent one of the most important causes of clinical attention. Febrile illnesses in the tropics are mainly zoonotic and have a broad etiology. The Colombian surveillance system monitors some notifiable diseases. However, several etiologies are not monitored by this system. In the present review, we describ...
Background
The emergence of highly transmissible SARS-CoV-2 variants has led to surges in cases and the need for global genomic surveillance. While some variants rapidly spread worldwide, other variants only persist nationally. There is a need for more fine-scale analysis to understand transmission dynamics at a country scale. For instance, the Mu...
Introduction:
Acute Respiratory Infections (ARIs) are considered one of the leading causes of morbidity and mortality worldwide. Children under five and older adults are most likely to die from this cause.

Background: The genus Borrelia is composed of two well-defined monophyletic groups, the Borrelia burgdorferi sensu lato complex (Bb) and the relapsing fever (RF) group borreliae. Recently, a third group, associated with reptiles and echidnas, has been described. In general, RF group borreliae use rodents as reservoir hosts; although neotropical bat...
Dentro de las variadas patologías del Sistema Nervioso Central (SNC), las dos entidades clínicas más importantes por su frecuencia de aparición en el mundo son las meningitis y las encefalitis.

The arboviruses (arthropod-borne virus) are viruses that require the hematophagous action of an arthropod vector for transmission to hosts (vertebrates). Arboviruses infect humans directly via enzootic or spillover cycles. However, dengue (DENV), chikungunya (CHIKV), and yellow fever viruses (YFV) in their cycles of urban transmission require compe...

According to recent scientific evidence, Brazil's wildfires are linked to deforestation. The blazes are surging in a pattern typical of forest clearing, along the edges of the agricultural frontiers (Fig. 1). Historical data shows the pattern of events: chainsaws or excavators open the way, then the wildfires, and these are followed by livestock, m...

Although the recent Zika virus (ZIKV) epidemic in the Americas and its link to birth defects have attracted a great deal of attention, much remains unknown about ZIKV disease epidemiology and ZIKV evolution, in part owing to a lack of genomic data. Here we address this gap in knowledge by using multiple sequencing approaches to generate 110 ZIKV ge...
