New Bacteria Discovered in Amazon Sand Flies: Potential Human Impact Under Study

Speedy Summary

• Researchers discovered a new species of Bartonella bacteria in phlebotomine sand flies in the Amazon National Park, Pará, Brazil.
• the DNA of this microorganism is similar to B.bacilliformis and B. ancashensis, which are known to cause Carrión’s disease in Andean regions.
• There is currently no evidence that the new species causes diseases in Brazil; further studies are needed to understand its implications.
• Phlebotomine sand flies were sampled from February 2022 to February 2023 across trails near Uruá and Tracoá rivers within the conservation unit.
• Researchers suggest similarities between Brazilian vector species (pintomyia serrana and Pintomyia nevesi) and those that transmit disease-causing bacteria (Pintomyia robusta and Pintomyia maranonensis) in Peru.
• Previous studies by the team identified other unknown Bartonella strains in Acre, another Brazilian Amazon state.
• Researchers aim to expand investigations into other biomes, animal reservoirs, vectors, and their potential role in human-related fever cases or co-infections with Leishmania.
• The study was supported by FAPESP projects (22/08543-2 & 22/16085-4) and published in scientific journal Acta Tropica.

Indian Opinion Analysis

The finding of a potentially pathogenic strain of bacteria related to known Andean diseases underscores the importance of advancing biological research for public health preparedness globally-even though India is geographically removed from this event. India shares tropical ecosystems with Brazil where vectors like sand flies thrive; thus understanding cross-regional microbial biodiversity could prove instrumental for Indian researchers tackling similar risks within their own biozones.

Furthermore, india’s experience with neglected vector-borne diseases such as Leishmaniasis provides an opportunity for collaboration on studying pathogens linked to these insects worldwide-including exploring connections between emerging pathogens like Bartonella spp., immune vulnerabilities, prolonged fevers without resolution-issues relevant given India’s stretched healthcare resources across rural zones.
