Summary: The aim of this project was to identify bacteriocinogenic Bacillus strains with activity against Staphylococcus spp., which could be used in the formulation of pharmaceutical antimicrobial preparations. The selected strains were evaluated for their safety, beneficial properties, and potential production of antimicrobials. The results suggest that the expressed antimicrobials from these strains could be realistically used in the treatment of Staphylococcus-associated infections. Biotechnological approaches need to be developed for cost-effective production, isolation, and purification of the expressed antimicrobials by these Bacillus strains.

Summary: Staphylococcus pseudintermedius (MRSP) is a commensal bacterium commonly found on the skin and mucosae of dogs, but can also cause various infections in both animals and humans. This study aimed to identify the occurrence of MRSP in infected patients, assess its antimicrobial resistance, and analyze its molecular structure. The findings showed a high incidence of multidrug-resistant MRSP in infected dogs, with surgical site infections being the most common. The study also revealed the dispersion of a particular sequence type associated with fluoroquinolone resistance, raising concerns for animal and human health due to limited treatment options for MRSP infections.

Summary: This study analyzed the species distribution and antimicrobial susceptibility of Staphylococcus and Mammaliicoccus species in a swine manure treatment plant in Southeastern Brazil. The results showed that S.cohnii and S.simulans were the most prevalent species, and a high level of antibiotic resistance was detected, especially to chloramphenicol. Gene detection revealed that all strains carried at least 2 resistance genes, and one strain carried all 11 investigated genes. The study also found high genetic similarity between strains isolated from different points of the treatment plant, indicating potential horizontal gene transfer.

Summary: Vascular shrubs growing along the draw-down zones of saline lakes have to develop adaptive mechanisms to cope with high salinity, erratic environmental conditions, and other stresses. Microbial endophytes from these plants play an important role in plant growth, health, and survival under stressful conditions. In this study, bacterial endophytes were isolated from shrubs growing along the draw-down zone of Lake Bogoria, and their potential for biocontrol of the bean root rot pathogen, Fusarium solani, was examined. Two isolates showed promising results in controlling the pathogen and promoting plant growth.

Summary: The physical-chemical characteristics of Minas Frescal cheese favor the growth of Staphylococcus spp. and the production of enterotoxins. Staphylococcus aureus growth in MFC samples is influenced by pH, temperature, and salt content, with the lowest growth rates observed at pH 5.80 and salt content of 1.7%, and the best temperature to prevent growth being 7.5 degrees C.

Summary: The aim of this study was to evaluate the antimicrobial and antibiofilm activity of Weissella cibaria, Weissella hellenica and Bacillus coagulans, isolated from equine skin, against biofilm-forming Staphylococcus aureus CCM 4223 and clinical isolate methicillin-resistant S. aureus (MRSA). The results showed that the selected isolates may have the potential for the prevention and treatment of biofilm-forming S. aureus infections.

Summary: This study investigated the occurrence of Staphylococcus aureus in the artisanal cheese production chain from unpasteurized milk and found that many strains exhibited antibiotic resistance and biofilm formation ability. It suggests that the production of raw milk cheeses may contribute to the spread of antibiotic resistance and virulent S. aureus.

Summary: This study conducted a partial nutritional analysis of banana fruits derived from six triploid Musa accessions grown in a coastal oasis in southern Tunisia, including total polyphenols, vitamin C, total soluble solids (degrees Brix), soluble sugars, and mineral constituents. The analysis revealed variations in pH values (5.44 to 6.01) and degrees Brix values (1.33 to 4.00 g/100 g (FW)) among different accessions. Carbohydrates were present in all tested samples, while sucrose was detected only in four accessions. Glucose, fructose, and sucrose were found in concentrations of 2.7, 3.37, and 1.8 g/100 g (FW), respectively. The total polyphenols content ranged from 46.0 to 55.08 mg GAE /100g (FW). Vitamin C was detected in smaller quantities. The mineral composition varied, with relatively large quantities of K, P, and Na, and medium levels of Mg and Ca. There were significant disparities in the mineral contents of banana samples. Micro-element composition, such as zinc, copper, iron, and magnesium, varied according to the tested accessions. The analysis showed a high Fe content of up to 1945 mg/100g (dried matter). Therefore, banana fruits can be recommended as a daily source of Fe, K, and other mineral elements.

Summary: The study investigated the prevalence, antibiotic resistance, and virulence characteristics of Staphylococci from various wastewaters in Ardabil, Iran. The most common species found were Staphylococcus aureus and Staphylococcus xylosus. Methicillin resistance was detected in a small percentage of S. aureus isolates, while multidrug resistance was observed in both coagulase-positive and coagulase-negative Staphylococci. Several genes associated with antibiotic resistance were identified, and the majority of S. aureus isolates exhibited multiple virulence factors. The presence of multidrug-resistant and virulent S. aureus in wastewater poses a significant health concern.

Summary: The concentrations of heavy metals in fresh fruits consumed in South Korea were investigated using inductively coupled plasma-mass spectrometry. Among the seven potentially toxic metals, only barium showed a significant negative correlation with lead in the studied fruits. The health risks associated with fruit consumption in the Korean population were found to be low, but continuous risk monitoring is necessary for children aged 1-2 years regarding lead contamination in apples.

Summary: In plants, pathogen resistance is regulated by specific transcription factor proteins binding to cis-elements in target genes' promoters. This study analyzed rice promoter sequences to identify WRKY13 binding motifs and their target genes. Further analysis involved identifying cis-elements, building 3D structures, docking studies, and molecular dynamic simulations to explore the interaction of WRKY13 with disease resistance-related genes. The study provides insights into the molecular mechanism of WRKY13 TF in disease resistance against rice fungal pathogens.
