Article Synopsis
- The study focused on detecting and analyzing Shiga toxin-producing E. coli (STEC) and Enteropathogenic E. coli (EPEC) in 771 fecal samples from dairy cattle in South Africa.
- Results showed that 42.2% of the samples were positive for STEC and 23.3% for EPEC, with a total of 53 different STEC serotypes and 19 EPEC serotypes identified.
- The findings highlight dairy cattle as a significant reservoir for these pathogens, indicating a need for further research to understand their potential impact on foodborne diseases in humans.
Article Synopsis
- The study focused on antibiotic resistance in micro-organisms from pigs and humans on a commercial farm in South Africa, comparing results from traditional methods and whole-genome sequencing (WGS).
- It found that pig isolates showed higher levels of antibiotic resistance and more diverse resistance genes compared to those from humans, with various bacterial pathovars identified at low frequencies.
- While a common sequence type complex (STc 10) was prevalent in both groups, the research revealed genetic diversity and differences in virulence and resistance profiles linked to their sources.
Bioadhesive materials and patches are promising alternatives to surgical sutures and staples. However, many existing bioadhesives do not meet the functional requirements of current surgical procedures and interventions. Here, we present a translational patch material that exhibits instant adhesion to tissues (2.

Objectives: This study sought to examine the associations of RV on bronchoalveolar lavage (BAL) granulocyte patterns and biomarkers of inflammation with age in children with treatment-refractory, recurrent wheeze (n = 616).
In this study, four antimicrobial growth promoters, including virginiamycin, josamycin, flavophospholipol, poly 2-propenal 2-propenoic acid and ultraviolet light, were tested for their capacity to induce stx-bacteriophages in 47 Shiga toxin-producing E. coli O157:H7 isolates. Induced bacteriophages were characterized for shiga toxin subtypes and structural genes by PCR, DNA restriction fragment length polymorphisms (RFLP) and morphological features by electron microscopy.
