A One Health Molecular Investigation and Exploratory Epidemiological Analysis of Cryptosporidium spp. in A Shared Human‐Animal Ecosystem

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A One Health molecular investigation of Cryptosporidium across humans, animals and the environment revealed the circulation of multiple zoonotic species and subtypes within a shared ecosystem. Molecular characterisation and phylogenetic analysis highlighted transmission at the human–animal–environment interface. The findings emphasise the importance of

Phylogenetic Analysis of the Most Common Chicken Coccidia, Eimeria acervulina, Isolated From Commercial Poultry Farms in Bangladesh

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
The ITS‐1 PCR assay detected 96.11% E. acervulina in coccidia‐positive faecal samples from commercial poultry farms. The sequence analysis revealed 15 genotypes and seven single‐nucleotide substitutions, indicating significant genetic diversity. This is the first report of molecular characterization of E. acervulina in Bangladesh.

Analyzing the Interaction between Tetrahymena pyriformis and Bacteria under Different Physicochemical Conditions When Infecting Guppy Using the eDNA Method

Animals
In the aquaculture system of ornamental fish, the interaction between bacterial microbiota and ciliate protozoa can prevent or promote disease outbreaks, and different physicochemical conditions will affect the relationships between them. We investigated

Quantifying Ion‐Specific Effects on the Size‐Exclusion Transport of Multi‐Sized Colloids in Porous Media Using a Novel Synthetic DNA Labeling Approach

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Colloids strongly adsorb pollutants and promote their co‐transport in aquatic environments, posing substantial ecological contamination risks. However, quantifying the size exclusion effect (SEE), a critical mechanism that enhances colloid transport, remains challenging in multi‐sized colloid systems, owing to limited high‐resolution labeling ...

Environmental Drivers of Nontuberculous Mycobacteria in Tropical Freshwater Systems

Environmental Microbiology, Volume 28, Issue 11, November 2026.
In tropical freshwater ecosystems, nontuberculous mycobacterial diversity and distribution is mainly driven by habitat and sample type, and local environmental factors such as sediment texture and depth. These findings highlight the importance of microhabitat conditions over broad biogeographic patterns in shaping mycobacterial communities.

Taxonomic Revision of the Globally Widespread Cryptic Rhynchomonas Morphospecies Complex

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Rhynchomonads are ubiquitously distributed, small, colorless, heterotrophic flagellates with confirmed occurrences in diverse aquatic and soil habitats. To date, Rhynchomonas nasuta (Stokes 1888) Klebs 1892 is the commonly accepted species. However, phylogenetic studies revealed considerable genetic divergence, suggesting that isolates of this

The kinetoplastid-specific transcription factor mtTF1 is essential for mitochondrial gene expression and maxicircle replication in Trypanosoma brucei.

PLoS Biology
Mitochondrial DNA replication and gene expression are essential for cell survival. In Trypanosoma brucei, a protozoan animal and human parasite, the mitochondrial RNA polymerase (mtRNAP, Tb927.11.5780) plays roles in both transcription and DNA ...
