Genetic Diversity and Virulence Factors of S. aureus Isolated from Food, Humans, and Animals
September 20, 2020
Staphylococcus aureus is a commensal bacteria in humans and animals are able to adapt to several environments. The purpose of this study was to compare the genetic profile of diversity and virulence of S. aureus strains isolated from food (29 strains), men (43 strains), and animals (8 strains). 80 lipase producing strain belonging Biobank of 360 isolates, the phenotype is identified as S. aureus, are selected. Confirmation of species made by strengthening the spA gene and 80% (64/80) of the strain was confirmed in this species. Profile virulence of each isolate was determined by PCR.
SEA gene coding for enterotoxin A was found in 53.1% of the strains, SAK gene, which codes for Stafilokinase, amplified in 57.8% of the strains, and, finally, HLB gene coding for β-hemolysin was amplified in 17.2%. Antimicrobial resistance profile is determined by the method of Kirby Bauer showed that the strain of the food served is more resistant to erythromycin (40.7%) and ciprofloxacin (18.5%), while the strains isolated from humans are to erythromycin (48.4%) and clindamycin (21.2%).
Also, the strain of the animal, a high resistance to erythromycin was observed (75%). The frequency of MRSA was 12.5% due to the presence of mec genes and resistance to cefoxitin. Of the total strain, 68.7% typed by PCR-RFLP using the enzyme AluI coa gene; derived from these restrictions, 17 profiles were generated. Profile 4 (490 bp, 300 bp) were the most frequent, contain a higher number of strains with a higher number of factors of virulence and antimicrobial resistance, which is associated with a greater adaptation to different environments. In this study, the genetic diversity of S. aureus strains from different foods, humans, and animals are found. It shows the evolution, genetic flexibility and, therefore, the adaptation of these microorganisms in different environments.

human and mouse genetic model of dendritic cell development and function
Dendritic cells (DC) develops in the bone marrow from haematopoietic progenitor that has many of the characteristics shared between mice and humans. human counterparts DC progenitor mouse has been identified by the joint signatures of their transcription and developmental potential. The new findings continue to revise the model DC ontogeny but well accepted that DC can be divided into two main functional groups.
DC classics including type 1 and type 2 subsets, which can detect different pathogens, produce specific cytokines and present antigens to polarize the CD8 + cells or CD4 + T particularly naive, respectively. In contrast, plasmacytoid DC function of innate and largely limited to the detection of viral infection and the production of type I interferon. Here, we discuss the development of genetic models of mouse DC and functions that have helped in ontogeny associated with the function, as well as how these findings can be translated into human DC and their ancestors.

Gene therapy concept was initially introduced in the 1960s. Since the early 1990s, more than 1900 clinical trials have been conducted for the treatment of genetic diseases and cancer, especially using viral vectors. Although various methods have also been made for the treatment of malignant glioma, it is difficult to target invasive glioma cells.
