Journal ArticleDOI
RNA polymerase beta subunit (rpoB) gene and the 16S-23S rRNA intergenic transcribed spacer region (ITS) as complementary molecular markers in addition to the 16S rRNA gene for phylogenetic analysis and identification of the species of the family Mycoplasmataceae.
TL;DR: Three-target sequence analysis was demonstrated to be a reliable and useful taxonomic tool for the species differentiation within the family Mycoplasmataceae based on their phylogenetic relatedness and pairwise sequence similarities.
Journal ArticleDOI
Mycoplasma testing of cell substrates and biologics: Review of alternative non-microbiological techniques.
TL;DR: The application of alternative nucleic acid-based, enzyme-based and/or recombinant cell-culture methods, particularly in combination with efficient sample preparation procedures, could provide advantages over conventional microbiological methods in terms of analytical throughput, simplicity, and turnaround time.
Journal ArticleDOI
Livestock abundance predicts vampire bat demography, immune profiles and bacterial infection risk

TL;DR: In this paper, the authors show that if resources amplify or dampen, pathogen transmission probably depends on both host ecology and pathogen interactions, and they also show that human activities create novel food resources that can alter wildlife-pathogen interactions.

TL;DR: Bats from high-livestock sites had higher microbicidal activity but lower immunoglobulin G and proportions of lymphocytes, suggesting more investment in innate relative to adaptive immunity and either greater chronic stress or pathogen exposure, suggesting feedbacks between demographic correlates of provisioning and immunity.
Journal ArticleDOI
Novel hemotropic mycoplasmas are widespread and genetically diverse in vampire bats.
Dmitriy V. Volokhov,Daniel J. Becker,Laura M. Bergner,Melinda S. Camus,Richard J. Orton,Vladimir E. Chizhikov,Sonia Altizer,Daniel G. Streicker +7 more
TL;DR: It is demonstrated vampire bats host several novel hemoplasmas and sheds light on risk factors for infection and basic transmission routes, and the potential of these bacteria to be transmitted between species should be investigated in future work.
