Data from: Spontaneous nongenetic variation of group size creates cheater-free groups of social microbes

Michaela Amherd, Gregory J. Velicer & Olaya Rendueles
In social organisms, cheaters that gain a fitness advantage by defecting from the costs of cooperation reduce the average level of cooperation in a population. Such “cheating load” can be severe enough to cause local extinction events when cooperation is necessary for survival, but can also mediate group-level selection against cheaters across spatially structured groups that vary in cheater frequency. In cheater-laden populations, such variation could be generated by the formation of new homogeneous groups...

Data from: Generalized bootstrap supports for phylogenetic analyses of protein sequences incorporating alignment uncertainty

Maria Chatzou, Evan Wade Floden, Paolo Di Tommaso, Olivier Gascuel & Cedric Notredame
Phylogenetic reconstructions are essential in genomics data analyses and depend on accurate multiple sequence alignment (MSA) models. We show that all currently available large-scale progressive multiple alignment methods are numerically unstable when dealing with amino-acid sequences. They produce significantly different output when changing sequence input order. We used the HOMFAM protein sequences dataset to show that on datasets larger than 100 sequences, this instability affects on average 21.5% of the aligned residues. The resulting Maximum...

Data from: The complex relationship of exposure to new Plasmodium infections and incidence of clinical malaria in Papua New Guinea

The molecular force of blood-stage infection (molFOB) is a quantitative surrogate metric for malaria transmission at population level and for exposure at individual level. Relationships between molFOB, parasite prevalence and clinical incidence were assessed in a treatment-to-reinfection cohort, where P.vivax (Pv) hypnozoites were eliminated in half the children by primaquine (PQ). Discounting relapses, children acquired equal numbers of new P. falciparum (Pf) and Pv blood-stage infections/year (Pf-molFOB=0-18, Pv-molFOB=0-23) resulting in comparable spatial and temporal patterns...

Data from: Naturally acquired antibody responses to more than 300 Plasmodium vivax proteins in three geographic regions

Plasmodium vivax remains an important cause of malaria in South America and the Asia-Pacific. Naturally acquired antibody responses against multiple P. vivax proteins have been described in numerous countries, however, direct comparison of these responses has been difficult with different methodologies employed. We measured antibody responses against 307 P. vivax proteins at the time of P. vivax infection, and at 2–3 later time-points in three countries. We observed that seropositivity rates at the time of...

Data from: Characterizing and comparing the seasonality of influenza-like illnesses and invasive pneumococcal diseases using seasonal waveforms

Matthieu Domenech De Cellès, Helene Arduin, Emmanuelle Varon, Cécile Souty, Pierre-Yves Boëlle, Daniel Lévy-Bruhl, Sylvie Van Der Werf, Jean-Claude Soulary, Didier Guillemot, Laurence Watier & Lulla Opatowski
The seasonalities of influenza-like illnesses (ILIs) and invasive pneumococcal diseases (IPDs) remain incompletely understood. Experimental evidence indicates that influenza-virus infection predisposes to pneumococcal disease, so that a correspondence in the seasonal patterns of ILIs and IPDs might exist at the population level. We developed a method to characterize seasonality by means of easily interpretable summary statistics of seasonal shape—or seasonal waveforms. Non-linear mixed-effects models were used to estimate those waveforms based on weekly case reports...

Data from: Screening test for neutralizing antibodies against yellow fever virus, based on a flavivirus pseudotype

Séverine Mercier-Delarue, Christine Durier, Nathalie Colin De Verdière, Jean-Dominique Poveda, VIncent Meiffrédy, Maria Dolores Fernandez Garcia, Stephane Lastère, Raymond Césaire, Jean-Claude Manuggera, Jean-Michel Molina, Ali Amara & François Simon
Given the possibility of yellow fever virus reintroduction in epidemiologically receptive geographic areas, the risk of vaccine supply disruption is a serious issue. New strategies to reduce the doses of injected vaccines should be evaluated very carefully in terms of immunogenicity. The plaque reduction test for the determination of neutralizing antibodies (PRNT) is particularly time-consuming and requires the use of a confinement laboratory. We have developed a new test based on the use of a...
