Observed frequency-independent torque in flagellar bacterial motors optimizes space exploration
(American Physical Society, 2012-12-17)
A surprising feature of many bacterial motors is the apparently conserved form of their torque-frequency relation. Experiments indicate that the torque provided by the bacterial rotary motor is approximately constant over ...
High Prevalence and Increased Severity of Norovirus Mixed Infections Among Children 12-24 Months of Age Living in the Suburban Areas of Lima, Peru
(Oxford University Press, 2015)
In an active diarrhea surveillance study of children aged 12-24 months in Lima, Peru, norovirus was the most common pathogen identified. The percentage of mixed (bacterial and noroviral) infections was significantly higher ...

Chitosan and cloxacillin combination improve antibiotic efficacy against different lifestyle of coagulase-negative Staphylococcus isolates from chronic bovine mastitis
(Nature Publishing Group, 2018-12-23)
Bovine mastitis affects the health of dairy cows and the profitability of herds worldwide. Coagulase-negative staphylococci (CNS) are the most frequently isolated pathogens in bovine intramammary infection. Based on the ...
Habitat heterogeneity and connectivity shape microbial communities in South American petlands
(Nature Publishing Group, 2016-05)
Bacteria play critical roles in peatland ecosystems. However, very little is known of how habitat heterogeneity affects the structure of the bacterial communities in these ecosystems. Here, we used amplicon sequencing of ...
Marine bacterial community structure resilience to changes in protist predation under phytoplankton bloom conditions
(Nature Publishing Group, 2016-03)
To test whether protist grazing selectively affects the composition of aquatic bacterial communities, we combined high-throughput sequencing to determine bacterial community composition with analyses of grazing rates, ...
Influence of allochthonous dissolved organic matter on pelagic basal production in a northerly estuary
(Academic Press Ltd - Elsevier Science Ltd, 2018-05)
Phytoplankton and heterotrophic bacteria are key groups at the base of aquatic food webs. In estuaries receiving riverine water with a high content of coloured allochthonous dissolved organic matter (ADOM), phytoplankton ...
Interactions of “de novo” designed peptides with bacterial membranes: Implications in the antimicrobial activity
(Elsevier Science, 2020-11)
Antimicrobial peptides are small molecules that display antimicrobial activity against a wide range of pathogens. In a previous work, by using model membranes we studied P6, a peptide that shows no antimicrobial activity, ...
Genomic signatures of pre-resistance in Mycobacterium tuberculosis.
(Springer Nature, 2021)
Recent advances in bacterial whole-genome sequencing have resulted in a comprehensive catalog of antibiotic resistance genomic signatures in Mycobacterium tuberculosis. With a view to pre-empt the emergence of resistance, ...
