ABSTRACT
As a frontal subject of life science, the medical immunology lessons are verification and complementary to theory lessons, and students need it to train their scientific ability and spirit. Therefore, some adjustments and explorations is needed in the experiments, for example, the data analysis of ELISA has been imported to the lessons to make them more closer to the practice. It' s shown that our lessons got welcomed by almost all students and is more helpful to them. The results playing an important role in improving our teaching effects in future.
ABSTRACT
To explore the epidemiological character of Methicillin-resistant Stapkylococcus aureus (MRSA) by the phenotyping and genotyping motheds and to investgate the source, transmission, and the spread of nosocomial MRSA infection, consequently, reducing the nosocomial infection of MRSA. In this study, 19 MRSA strains were isolated from patients and environment in a hospital in two months. Patterns of resistantce against 16 antimicrobial agents and pulsed-field gel electrophoresis ( PFGE) of these strains were analyzed to find the relationship among those isolates Clustering analysis was made from the patterns. Some isolates with high homology was found in 19 MRSA, 11 of them belong to type A, and 8 of them belong to the same subtype A1. They were endemic in burn ward, oncological ward and ICU. In addition, 4 isolates were clustered into group B, all found in the same ward of burn unit Thus, our results indicated a outbreak of MRSA ( A type) in this hospital and the potential prevalence of MRSA (B type) , which might be mediated by health care stuff. It is essential to enhance the infection control implementation and to utilize the PFGE genotyping system for the real-time surveillance of MRSA.
