Article Synopsis
- Hemotropic mycoplasmas, or hemoplasmas, are a group of bacteria found in various animal species and the study aimed to explore their presence and genetic diversity among small non-flying mammals in Brazil, focusing on environmental and animal factors affecting infection rates.* ! -
- Out of 257 sampled animals, 33.8% tested positive for hemotropic mycoplasma DNA, with the highest infection rates observed in the regions of Ponta Grossa and Cruz Machado and specifically in the rodent species Oligoryzomys.* ! -
- The study identified two phylogenetic clades of hemoplasmas and showed that males were significantly more likely to be infected than females, emphasizing the influence of
Mixed infections by different species or genotypes are a common and puzzling phenomenon. Therefore, it is critical to refine the diagnostic techniques and to understand to what extent these methods detect trypanosomes. We aimed to develop an accessible strategy to enhance the sensitivity of the hemoculture, as well as to understand the limitations of the hemoculture and the blood clot as a source of parasitic DNA.

For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown.
