ABSTRACT
To investigate the infection of Yersinia enterocolitica in Dengfeng City ,the strains were isolated from livestock and poultry .The strains were detected with biochemiological methods ,serological methods ,and virulence genes were detected with PCR .A total of 105 strains of Yersinia enterocolitica were classified from 1 285 stool samples ,the total isolation rate was 8 .17% .Among the total isolated strains ,17 strains were classified from dogs with a rate of 17 .35% and 35 strains from pigs with 13 .62% .Twelve strains were O ∶3 serotype (13 .48% ) ,12 strains were O ∶5(13 .48% ) ,and 14 strains were O ∶8 (15 .73% ) .Ail+ ,ystA+ ,yadA+ and virF+ accounted for 12 .36% ,and ystB+ accounted for 42 .70% .In conclusion ,the pigs and dogs were important animal hosts ,which may play the major role in humans'infection .
ABSTRACT
Objective To investigate the clinical effect of high developmental dislocation of the hip in patients with total hip replacement operation to take biology.Methods Thirty-six cases of high developmental dislocation of the hip by patients as the object of study from January 2011 to February 2014 in the First People' s Hospital of Shangqiu, all patients underwent cementless total hip joint replacement operation, 6 months to 2 years after surgery, observed the clinical effect of all patients before and after treatemnt.Results The operation time was 1.20-3.0 h,the average operation time was (2.13±1.01) h,amount of bleeding during the operation of 300.00-700.00 ml,the average amount of bleeding was (342.43±34.23) ml;follow up of 6 months to 2 years, all patients had no prosthesis loosening and dislocation of the hip;all patients after treatment, Harris score (81.56± 14.34) points, better than that before treatment, the difference was statistically significant ((54.34 ± ±9.78) points,P=0.009);The excellent and good rate of all the patients after the treatment (97.22％) .Conclusion The clinical effect of high developmental dislocation of the hip by total hip replacement operation in patients taking biological type significantly, has the advantages of simple operation, effectively relieve pain, improve the life quality of patients and other advantages, the ideal treatment method can be used as high developmental dislocation of hip.
ABSTRACT
The food poisoning caused by Bacillus cereus occurs in Kunming or Yunnan Province sometimes.The aim of our survey is to prevent and control this kind of food poi- soning in the future.The result shows that the positive rate is 19.20% and the degree of contamination differs in the different kinds of food,the dairy products being contaminated most seriously of all.The bacteria in the contaminated food number mostly 10~2～10~4 per gram,Though it is not very high,the presence of Bacillus cereus is so wide that we showld pay much attention to it. Abut 97.65% of Bacillus cereus can be biologically classified and the most com- mon types are 2,8 and 10.About 92.98% of Bacillus cereus can be classified according to the serological type,and type 3 is the most predominant one and type 1 the second.In the dairy products,biological types 2 and 8 make up 54.55% and serological type 1 36.36%. The bacteria isolated from the food are highly sensitive to erythromycin,chlor- amphenicol,gcntamycin,streptomycin and kanamycin.
