Tenth retraction appears for Jesús Lemus, this one in PLOS ONE

Just two days ago, we covered the ninth retraction for Jesús Lemus, “the veterinary researcher whose work colleagues have had trouble verifying, including being unable to confirm the identity of one of his co-authors.” And already another of his retractions has appeared in one of our daily alerts.

This one appears in PLOS ONE, for “Infectious Offspring: How Birds Acquire and Transmit an Avian Polyomavirus in the Wild:”

“Ephemeral nature” of samples — and co-author — leads to ninth Jesús Lemus retraction

Jesús Lemus — the veterinary researcher whose work colleagues have had trouble verifying, including being unable to confirm the identity of one of his co-authors — has notched his ninth retraction.

It’s a clear and comprehensive notice, from the Journal of Applied Ecology, despite the bizarre nature of the case:

Misuse of data forces retraction of paper on sow’s milk

A group of veterinary researchers from Taiwan has lost their 2012 paper in the Journal of Chromatography B for misuse of propriety material.

What that means we’re not quite sure, but we have a guess.

The article, “Pilot production of recombinant human clotting factor IX from transgenic sow milk,” was published last July by four scientists at the Animal Technology Institute of Taiwan.

But, as the retraction notice explains, the paper didn’t stick:

Orangutan-Ebola link in PLOS ONE paper under scrutiny

PLOS ONE has issued a fascinating expression of concern about data collection in a paper it published late last year on the possible spread of deadly viruses among Indonesian orangutans. The case has been brought to the attention of the Indonesian government, but more on that in a moment.

The article, published last July by an international group of primate scientists led by Chairul Nidom, a virologist at Indonesia’s Airlangga University, sounded an alarm about “wild” orangutans in Borneo: Blood tests of 353 “healthy” animals showed antibodies for viruses akin to Ebola. What’s more, the filoviruses viruses to which the antibodies responded, as New Scientist and other outlets reported when the original paper came out, included strains not previously seen outside Africa (as well as Marburg, another deadly infection).

The article immediately prompted two comments. The first, by a poster called orangutanborneo, raised questions about the scale and logistics of the project:

Jesús Lemus notches his eighth retraction

The carcasses are piling up.

Jesús A. Lemus now has eight retractions. Here’s the notice for the most recent:

Retraction seven appears for Jesús Lemus

The retractions keep coming for Jesús A. Lemus. Here’s the notice for retraction seven, in Molecular Ecology:

Retraction six appears for Jesús Angel Lemus

Jesús A. Lemus, he of the likely ghost author and questionable data, has earned his sixth retraction, this one in Biology Letters.

Here’s the notice for “Stress associated with group living in a long-lived bird:”

Tick-borne disease paper retracted for data reuse

Medical and Veterinary Entomology has retracted a 2010 paper by a group of German researchers who populated the article with data from previously published studies.

The article, titled “Established and emerging pathogens in Ixodes ricinus ticks collected from birds on a conservation island in the Baltic Sea,” looked at the potential role of migrating birds in the spread of tick-borne infections such as Lyme disease and babesiosis. Here’s the abstract:

Not immune: Jesús A. Lemus earns another Expression of Concern

Jesús A. Lemus, the Spanish researcher whose work has left a lot of people questioning his data, has another Expression of Concern for his resume.

Here’s the notice, from Functional Ecology:

A pair of expressions of concern in PLOS ONE over vet science papers

PLoS ONE has issued two Expressions of Concern on unrelated studies, each of which offers plenty to be concerned about — and not just about the research itself.

One is a casualty of our old friend,  Jesús Lemus, the Spanish veterinary scientist accused of fabricating his data.

The article, titled “The PHA-Skin Test Reflects Acquired T-Cell Mediated Immunocompetence in Birds,” was published in September 2008 and cited 61 times, according to Google Scholar.

Back in April, the publisher posted this comment to the paper:
