Abstract
Juan A. Fargallo, Pablo Vergara, Deseada Parejo and Eva Banda, as co-authors of the article published in PLOS ONE (2010) titled “Natural Cross Chlamydial Infection between Livestock and Free-Living Bird Species”, request the retraction of this publication. The Ethics Committee of the Spanish Superior Council of Scientific Research (CSIC) has carried out an investigation in relation to concerns about potential scientific misconduct by Jesus A. Lemus, who was also a co-author of this article. The investigation has questioned the validity of the laboratory analyses conducted by Dr. Lemus in relation to this study, and was unable to establish at which laboratories the analyses were conducted. Specifically, the authors have been unable to verify the validity of the Chlamydophila analyses for sheep abortions, sheep faeces, sheep stable dust, kestrel nest dust and insects. There are also concerns about the validity of the results obtained for the Chlamydophila serovar characterization, genetic diversity and MSLT analyses for Chamydophila. As a result, the authors wish to retract the article.
Highlights
Cross-species infection is a major cause of emerging infectious diseases [1,2,3]
Protein electrophoresis showed that both kestrel species from LL showed higher levels of c-globulins than kestrels from Campo Azalvaro (CA) and Los Monegros (LM), being this difference statistically significant (GLMM, F 2,65 = 47.73, P,0.001, Fig. 1)
Lesser kestrels showed higher values than common kestrels (GLMM, F 1,65 = 15.47,P,0.001, Fig. 2). This was due to the between-species difference found in LL while no between-species differences were found in CA and LM
Summary
Cross-species infection is a major cause of emerging infectious diseases [1,2,3]. The economic influence of the animal industry has promoted many investigations regarding the potential of wildlife as a reservoir of cattle and poultry diseases [4,5]. Avian chlamydiosis is a well-known human disease caused by the bacterium Chlamydophila psittaci [7,8,9,10] and contracted from poultry and wild birds, pet bird (mainly parrots) are still considered the primary cause [11,12]. Isolates have been reported from more than 460 avian species [9] as well as from some mammals, such as hares and muskrats [12,13]. In birds it is often systemic and infections can be unapparent, severe, acute or chronic with intermittent shedding [12]. Stress will commonly trigger the onset of severe symptoms, resulting in rapid deterioration and death [18,19]
