  Enterotoxigenic Staphylococcus aureus is a main cause of Staphylococcal Food Poisoning (SFP). Here, researchers characterized the antimicrobial resistance, distribution and expression of enterotoxin genes of 41 Methicillin-Resistant S. aureus (MRSA) isolated from bovine mastitis milk and SFP cases. Apart from three SFP-acquired isolates which could produce extended-spectrum β-lactamases, all the others carried mecA gene and expressed the penicillin-binding protein 2a. The 92.7% of MRSA isolates tested showed twenty two multi-drug resistant patterns among which SFP-acquired isolates had higher resistant rate and the MIC50/90 values of cefotaxime, amikacin, azithromycin, ciprofloxacin and gentamicin than those of milk-acquired isolates. The 95.1% of MRSA isolates carried at least one Staphylococcal Enterotoxins (SEs) gene and could produce the corresponding classical SEs, the differences in the prevalence of enterotoxigenic MRSA observed between milk-acquired and SFP-acquired isolates were not statistically significant. Six SEs genotypes were found, among which the genotypes sea-seg-sei-seln-selm and sea-seb-sec-seg-sei-seln-selm predominated, respectively in milk-acquired and SFP-acquired isolates.

  In order to simplify and optimize the complicated operational activity model OV-5 during the design process of architecture framework, this thesis put forward a model analysis and optimization method of operational activities based on the Colored Petri Net. First, the OV-5 model will be hierarchically decomposed according to the different business domains. Then, transform the operational activity model to the Colored Petri Net model and finally simplify the Petri net model according to different requirements. Though the performance of the Petri model, one can testify the effectiveness of the model simplification to realized the optimization of the operational activity model. After, the thesis testifies the model through the analysis of a case.
