is a Gram-negative bacterium that has been linked to serious illnesses in both humans and animals. The presence of hemolysin, a virulence factor, is critical in the development of -related illnesses. As a result, precise and timely detection of the hemolysin gene is critical for efficient diagnosis and prevention of many illnesses. The PCR is used in this study to detect the hemolysin gene of in a novel, fast, and highly sensitive one-step technique. Specific primers were constructed to amplify a conserved area within the hemolysin gene to achieve both specificity as well as sensitivity. The PCR assay was rigorously optimized, taking temperature, primer concentration, and reaction time into account, in order to maximize the efficiency and reliability of this method. In conclusion, this method's simplicity, sensitivity, and specificity make it highly promising for regular diagnostic applications. Its application would allow for the early detection of infections, allowing for more effective treatment and control methods.

Introduction: is the most common uropathogen in humans, dogs and cats. Dietary consumption of cranberry () is known to be associated with a reduction in uropathogenic (UPEC) adhesion to human and canine urinary epithelial cell lines, but this has not been shown in cats.
Material And Methods: Six neutered domestic cats, one male and five females, were randomly fed three diets successively, one containing 0.

Developing simple and efficient multi-gene expression systems is crucial for multi-trait improvement or bioproduction in transgenic plants. In previous research, an -based bicistronic system from the nonpathogenic fungus efficiently expressed multiple enzyme proteins in yeast and maize, and the heterologous enzymes successfully performed their catalytic activity to reconstruct the biosynthetic pathway in the host organism. Unlike enzyme proteins, some heterologous functional proteins (such as insecticidal proteins) are dose-dependent and they need to express sufficient levels to perform their biological functions.

As a zoonotic pathogen, serotype 2 (SS2) can cause severe diseases in both pigs and humans, and develop resistance to antibiotics. Plant natural compounds are regarded as promising alternatives to conventional antibiotics. Phillyrin is the major bioactive components of Chinese herbal medicine Forsythia suspensa.

The highest hemolytic activity of M. morganii cultivated in urine with low urea concentration (23 and 82 mmol/liter) was observed between 3rd and 4th hours of post-inoculation, while in urine with standard urea level (117 mmol/liter), the activity was observed at 5th hour of post-inoculation.

Hemolysin co-regulated protein 1 (Hcp1) is a component of the cluster 1 Type VI secretion system (T6SS1) that plays a key role during the intracellular lifecycle of Burkholderia pseudomallei. Hcp1 is recognized as a promising target antigen for developing melioidosis diagnostics and vaccines. While the gene encoding Hcp1 is retained across B.
