ABSTRACT
Objective To explore the drug sensibility of Brucella from bovine and sheep in Xinjiang.Methods Using paper diffusion method,19 drugs of 8 kinds of antibiotics including aminoglycosides,macrolides,sulfonamides,tetracyclines,β-lactams,fluoroquinolones,chloramphenicols and rifamycins,were tested.Drug sensitivity test was conducted on 57 Brucella strains isolated from bovine and sheep in Xinjiang from 2010 to 2016.Results The 57 Brucella strains were highly sensitive to doxycycline,tetracycline,streptomycin,tobramycin,gentamicin,amikacin,amoxicillin,ofloxacin,fleroxacin,ciprofloxacin and chloramphenicol,with the sensitivity rates were all higher than 90％;and they were highly resistance to azithromycin,clarithromycin and bactrim,with the drug resistance rates were all higher than 80％.Conclusion Brucella from bovine and sheep in Xinjiang is sensitive to tetracyclines,aminoglycosides,β-1actams,fluoroquinolones and chloramphenicols.
ABSTRACT
Objective To understand the situation of knowledge,attitude and practice (KAP) of sheep farmers and field veterinarians towards brucellosis prevention,and find out the potentially influential factors.Methods From March to September in 2017,1 067 sheep farmers and 401 field veterinarians were selected as participates,and questionnaire survey was carried out.Percentage rate was used to describe the situation of KAP.Nonparametric test was used to compare the KAP score difference.Results The overall awareness in sheep farmers and field veterinarians was 64.2％ and 80.1％,respectively.In addition,there were 17.3％ (185/1067) sheep farmers and 12.2％ (49/401) field veterinarians had never heard of brucellosis.The knowledge awareness in sheep farmers and field veterinarians was 62.6％ and 79.0％,respectively,75.8％ and 83.8％ of them had positive attitude to brucellosis prevention,54.1％ and 77.6％ of them had good practice habit.They hoped in the future,more information could be received through TVs,and then was internet or broadcasting.Sheep farmers who from first class region,age less than 45 years,education higher than junior high school,feeding time less than 5 years and sheep ever infected with brucellosis (U =4.85,3.08,3.29,2.20,6.62,P ＜ 0.05 or ＜ 0.01),had higher KAP scores than others.Field veterinarians,who had lower education,had lower KAP scores (U =4.29,P ＜ 0.01).Conclusions The awareness of sheep farmers and field veterinarians still need to improve and strengthen.Some suggestions are put forward:improve intervention pattern,optimize content and method,pay attention to use new media.
ABSTRACT
Objective To study a wavelet method for acquiring the characters of pulse wave based on the principle of wavelet transform which can effectively solve the problem of inaccuracy of the conventional methods. Method The method of wavelet module maximum was used to divide the pulse wave according to periods and basically decomposed it, by arranging in time order and symbolizing the module maximum character points of pulse wave signal at the ascending and descending edges as well as the crest and trough. Result Through the method, the unobvious dicrotism, trail wave and the anomalistic wave appearing at the ascending and descending edge of the main wave, and multi-scale characters and all kinds of characters in time domain of pulse signal were further acquired more accurately. Conclusion Simplicity, quickness and accuracy are achieved by focusing on the character points of pulse signals. It provides a new means for further studies of classification and identification of pulse signals.
