Objective To report and analyze the changes of bacterial species and resistance to antibiotics in the burn center from 1993 to 2007. Methods Bacterial identification and susceptibility test were performed by applying VITEK-AMS system. Results A total of 4 762 strains were isolated,including 60 species of 21 genera. Pseudomonas aeruginoasa (PA) was the most common organism (36. 79%), and its isolating rate was 36. 79%; in 2006, the highest isolating rate of PA was 51.6%.The isolating rate of Staphylococcus aureus was 14.09 %, next to that of PA; followed by Enterococci faecalis, Acinetobacter, Escherichia coli, Enterococci faecium, Enterobaeter cloacae and Staphylococ-cus epidermidis, and the 8 kinds of germs shared 78. 12% of bacterial isolates (3 746/4 762). The an-tibiotic resistance rate of Pseudomonas aeruginosa was increasing year by year; it was vitally resistant to the third generation eephalosporins and imipenem. Conchtsion The predominant species of bacteria from burn center is Pseudomonas aeruginosa, and RA isolates are multi-resistant to antibiotics. The i-solating rates of Enterococeus faeealis and Acinetobacter are increasing. This implied the importance of rational and correct use of antibiotics about control of burn infections as well as avoidance of abusage of broad-spectrum antibiotics.

Objective To systematically study the development and morphological changes of Taenia solium cysticerci in the period from the appearance to maturation. Methods Pigs were orally infected with T.solium eggs. Autopsies were made periodically to get tissue specimens and examine the distribution of cysticerci. Cysticerci were excised, pressed between two microscopic slides for microscopical observation. Sections were also made for histological study. Results Cysticerci distributed mainly in muscles, secondly in brain, liver, lung and kidney. The size of cysticerci was highly variable at different parts or even in the same part of the same host. The early stage cysticercus was observed on the 19th day without suckers and hooklets on the scolex region, and was only found in skeletal muscles. Histological examination revealed that early development of the scolex became obvious. No cysticerci were found in other tissues. At 30 d, the cysticerci possessed hooklets and brood suckers. With a longer duration of infection, the diameter of suckers and length of hooklets both increased. Larger suckers and more folds on scolex appeared 60 d later. Morphologically, cysticerci after 60 d were similar to those found at 60 d. Degenerated cysticerci were found at every stage. Conclusion Cysticerci appear in about 19 days after the pig was infected with eggs of T.solium and the duration needed for maturation is about 60 d.
