Article Abstract
Objective: The increase and prevalence of multidrug-resistant bacteria in livestock animals are serious public health concerns. This study aimed to identify the presence of the TEM gene in extended-spectrum beta-lactamase (ESBL)-producing isolated from rectal swabs of apparently healthy pigs in Malang District, East Java, Indonesia.
Materials And Methods: A total of 120 rectal swab samples were collected from the pigs. The rectal swabs were screened for the presence of using standard microbiological identification procedures. The Kirby-Bauer disk diffusion method identified multidrug-resistant . Five different classes of antibiotics were used to identify multidrug-resistant isolates, including Ciprofloxacin, Trimethoprim, Tetracycline, Streptomycin, and Aztreonam. Multidrug-resistant isolates were characterized for the presence of ESBL using double-disk synergy test methods. The presence of TEM genes was determined using polymerase chain reaction methods.
Results: The results of this study indicated that 107 (89.2%) out of 120 samples analyzed were positive for isolates. A total of 32 (29.9%) isolates were identified to be multidrug-resistant and further subjected to molecular testing. The molecular analysis revealed (5; 15.6%) isolates to harbor the TEM gene.
Conclusion: The results of this study revealed that pigs and products of pork origin must be considered a source of transmission of ESBL-producing to public health important under the food chain.

Ethnopharmacological Relevance: YangXue QingNao Wan (YXQN) is a compound Chinese medicine comprising of 11 traditional Chinese medicinal herbs, including Angelica sinensis, Ligusticum chuanxiong, and Paeonia lactiflora, etc. Previous studies in our laboratory have demonstrated that YXQN improved cerebral microcirculation in hypertensive rats. However, its efficacy and underlying mechanisms in treating vascular dementia (VaD) remain unclear.

While the global dissemination of extended-spectrum β-lactamases (ESBLs) in clinical isolates from various animals is well-documented, research on Klebsiella pneumoniae in Trichomonas gallinae-infected pigeons, particularly concerning antibiotic resistance genes in China, remains limited. This study aimed to investigate the relationship between oral harmful microbiota in pigeons and T. gallinae infection, as well as to isolate K.

The increasing presence of nanoplastics (NPs) and synthetic antioxidants like 3-tert -Butyl-4-hydroxyanisole (3-BHA) in the environment has attracted widespread attention about their combined toxicological effects on human health, particularly on renal function. This study explored to the combined impacts of NPs and 3-BHA at environmentally relevant concentrations on sub-chronic kidney injury in mice. Firstly, our results confirmed that the accumulation of 80 nm NPs in renal tissues, leading to structural abnormalities such as reduced mitochondrial cristae and increased empty bubbles in mice by transmission electron microscope (TEM) analysis.

Microplastics (MPs) and heavy metals (HMs), well-known environmental pollutants, have attracted widespread attention owing to their increasing threats. However, the interactions of MPs and chromium (Cr) at the microscale remain poorly understood, and the effects of environmental transformation on their toxicity remain controversial. The influences of light irradiation on their conversion were investigated using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS).
