Effects of Luteolin on Biofilm of and Its Therapeutic Effect on Rat Endometritis.

is an opportunistic pathogen that causes suppurative infections in animals. The development of new anti-biofilm drugs will improve the current treatment status for controlling infections in the animal husbandry industry. Luteolin is a naturally derived flavonoid compound with antibacterial properties.

In vitro Antibiotic Susceptibility, Virulence Genes Distribution and Biofilm Production of Isolates from Bovine Mastitis in the Liaoning Province of China.

Purpose: The aim of this study was to identify the subtype, characterize the antimicrobial resistance, determine the virulence gene distribution, and analyze the biofilm production of isolates from bovine mastitis milk samples in the Liaoning Province of China.

Materials And Methods: In total, 56 isolates were collected and identified in this study; the isolates were divided into different types based on the sequence of the polymorphic X region of the gene. Additionally, antimicrobial susceptibility was investigated using the broth microdilution method, and 18 virulence genes were detected using PCR.

Luteolin Showed a Resistance Elimination Effect on Gentamicin by Decreasing mRNA Expression in .

is a common inhabitant of mucosal surfaces in animals and causes a variety of infections, including endometritis, mastitis, and liver abscessation, in dairy cows. Many antimicrobial agents are used for treatment of infections caused by ; however, antibiotic resistance has recently become a serious problem. The objective of this study was to characterize the effect of the efflux pump-encoding multidrug and toxic compound extrusion () gene on antibiotic resistance in isolates from cows with signs of endometritis.

The phylogenetic group, antimicrobial susceptibility, and virulence genes of Escherichia coli from clinical bovine mastitis.

Bovine mastitis is still a central problem on dairy farms despite control programs, and Escherichia coli is a crucial pathogen during the development of bovine mastitis. The virulence genes, antimicrobial susceptibility, and mortality of mice infected with different E. coli isolates from bovine mastitis were determined in this study.

Antibacterial and antioxidant properties of various solvents extracts of Abutilon theophrasti Medic. leaves.

This paper described the extraction procedure of six extracts from Abutilon theophrasti Medic. leaves and evaluated antioxidant and antibacterial activity of different extracts by hydroxyl radical, DPPH radical scavenging, broth micro-dilution and agar-well diffusion methods. The six extracts were prepared by the two extraction procedures: (I) water was the extraction solvent; (II) 90% alcohol extract was extracted by petroleum ether, chloroform, ethyl acetate and n-butanol in turn.

Trueperella pyogenes isolated from dairy cows with endometritis in Inner Mongolia, China: Tetracycline susceptibility and tetracycline-resistance gene distribution.

Trueperella pyogenes plays a crucial role in endometritis pathogenesis and is also associated with many infections, including metritis, mastitis, arthritis and liver abscessation, in many domestic animals. In this study, we investigated the prevalence of tetracycline resistance in T. pyogenes isolated from dairy cows with endometritis in Inner Mongolia, China, and we assessed tetracycline-resistance gene distribution among the isolates.

Resistance to β-lactam antibiotic may influence nanH gene expression in Trueperella pyogenes isolated from bovine endometritis.

Virulence could be modulated by many instinctive and environmental factors including oxygen, osmolarity and antimicrobial agents. This study aimed to investigate the correlation between drug resistance and the nanH expression in Trueperella pyogenes (T. pyogenes).
