Can chick meconium serve as a source of biomarkers linked to hatchling quality and the age of parent stock?

One possible approach to selecting chicks based on quality involves identifying biomarkers in biological samples. Concurrently, understanding the metabolic profile of chicks from different-aged breeders is essential for developing strategies to mitigate the age-related effects on hatchability. This study investigated whether chick quality and breeder age influence the metabolic profile of layer chick meconium.

Single-Nucleotide Polymorphisms in MMP3, TIMP1, and MTR Genes are Associated With Delayed Deciduous Tooth Eruption.

To analyze whether the single-nucleotide polymorphisms (SNPs) in Matrix metalloproteinases 2, 3, and 9 (MMP2, MMP3, and MMP9), Tissue Inhibitor of Metalloproteinases 1 and 2 (TIMP1 and TIMP2), methionine synthase (MTR) and methionine synthase reductase (MTRR) influence delayed deciduous tooth eruption (DDTE). This cross-sectional study included 1060 biologic unrelated children (aged between 6 and 36 months) of both sexes, selected from 25 public schools in Nova Friburgo, Rio de Janeiro, Brazil. Oral examination was conducted and DDTE was defined by the absence of gingival eruption according to a chronology based on the Brazilian population.

Equine endometrial bacteria inhibition by metabolite and extracellular vesicles of Lactobacillus acidophilus and lactiplantibacillus plantarum.

Endometritis is one of the main reproductive disorders in mares and due to the increasing prevalence of antibiotic resistance, the use of probiotics in the prevention and treatment of endometritis in mares has gained interest, given their potential to restore and maintain a healthy uterine microbiota. Therefore, the aim of this study was to evaluate the antimicrobial properties of total metabolites of Lactobacillus acidophilus (LA) and Lactiplantibacillus plantarum (LP) against common equine endometrial pathogenic bacteria in vitro (Acinetobacter baumannii, Escherichia coli (1), Escherichia coli (2), Escherichia coli (3), Escherichia coli (4), Enterobacter cloacae, Streptococcus equi, Staphylococcus warneri, Actinobacillus equi and Klebesiella pneumoniae), as well as to assess their low molecular weight metabolites (loM) and extracellular vesicle (EVs) inhibition capacity over a multidrug-resistant E. coli isolated from mares with clinical endometritis.

In vitro evaluation of the antimicrobial effect of ZnO:9Ag nanoparticle and antibiotics on standard strains of Leptospira spp.

Silver nanoparticles are recognized for potent antimicrobial properties against pathogenic bacteria, crucial in addressing the severity of leptospirosis, where an ideal treatment is lacking. This study focuses on assessing the antimicrobial efficacy of silver-doped zinc oxide nanoparticles (ZnO:9Ag) on standard Leptospira spp. strains (six species and ten serovars).

The Use of Technology in the Prevention of Infections Associated with Urinary Catheterization.

(1) Background: Urinary tract infections (UTIs) are caused by the proliferation of pathogenic microorganisms, and they are the second most common hospital-acquired infections, with catheter-associated UTIs (CAUTIs) accounting for about 40% of these nosocomial infections. This review aims to identify the impact of technology on preventing infections in patients with urinary catheters; (2) Methods: The search was conducted in April 2024 through the EBSCOhost platform, with access to the American Search Complete, CINHAL Ultimate, Medline databases, and through the Scopus database; (3) Results: In total were included eight articles in this review. Technology interventions can significantly reduce the incidence of CAUTIs, decrease the duration of catheter use, improve diagnosis, and enhance patient safety; (4) Conclusions: Technological advancements show significant benefits in reducing infection rates and improving patient outcomes, like shorter hospital stays and comfort.
