Effects of probiotic Enterococcus faecium DMS 10663 NCIMB 10415 on diarrhoea and performance of sucking piglets were evaluated in a double-blind, placebo-controlled study. Piglets from treatment group (TG, n=56) and placebo group (PG, n=53) sows were included in the study. Immediately after birth and at day 2 and 3 post natum, each of the TG piglets received 2.8×10(9) colony forming units (cfu) per os. From day 4 until weaning (day 26), 1.26×10(9) cfu E. faecium/piglet were given twice a day via a liquid additive. Piglets already suffering from diarrhoea additionally got a glucose-electrolyte solution enriched with 2.9×10(8) (week 1) and 5.8×10(8) (week 2) cfu E. faecium/day. PG piglets received corresponding placebo preparations. A score was defined to characterise the severity of diarrhoea, including accompanying symptoms. The counts of viable born, stillborn and weaned piglets were similar in TG and PG litters (P>0.05). The probiotic treatment mitigated incidence and severity of diarrhoea (P<0.05) with no impact on diarrhoea length (P>0.05). Probiotic treatment improved daily weight gain (P<0.05) yet with no provable effect on body weight at weaning (P>0.05). The additional supply of E. faecium in piglets suffering from diarrhoea had no further beneficial effect.

Ligand-functionalized InP-based quantum dots (QDs) have been developed as an innovative class of nontoxic photosensitizer suitable for antimicrobial applications, aimed at reducing or preventing pathogen transmission from one host to another via high contact surfaces. A hot injection method followed by functionalization via ligand exchange with 9-anthracene carboxylic acid (ACA) yielded the desired core/shell InP/ZnSe/ZnS QDs. Transmission electron microscopy (TEM) revealed these QDs to be uniform in size (∼3.

Objective: This study investigated the distribution and changes in pancreatic infections among patients with acute pancreatitis (AP) from 2019 to 2023, while exploring the impact of multidrug-resistant bacterial infections on the prognosis of patients with poor outcomes.
Methods: This study included patients diagnosed with SAP between 2019 and 2023 and collected the demographic and clinical characteristics of all participants. Based on routine clinical microbiological culture results, the distribution and drug resistance of pathogens associated with pancreatic infections were analyzed.

Antibiotics play a fundamental role in protecting millions of lives from infectious diseases. However, an important drawback of antibiotic treatment is that each advancement was followed by the development of resistance. This is due to the fact that the majority of pathogenic bacteria are capable of becoming resistant to a number of antimicrobial agents.

Article Synopsis
- Pseudomonas aeruginosa is problematic in healthcare due to its high antibiotic resistance, highlighting the need for new antimicrobial solutions.
- A study focused on isolating a new bacteriocin from Enterococcus faecium found in stool samples, which showed promise against multidrug-resistant P. aeruginosa.
- The purified bacteriocin, enterocin GH, demonstrated significant antibacterial and antibiofilm activity against P. aeruginosa, outperforming controls in laboratory tests.
