昆蟲病原線蟲共生細菌的型態變異The percentage of autumn degradation bacteria was the biggest, it was 0. 547 %. among degradation bacteria genus, the bacillus proportion in each season was the biggest, that was 44. 44 %, 50. 00 %, 48. 15 % and 47. 22 % in spring, summer, autumn and winter respectively, other bacteria genus ' s proportion were less than bacillus. this was probably related to the basic proterties of soil, the alternation of four seasons, the change of temprature and the difference of vegetation were fairly suitable to the growth of bacillus
在土壤細菌總數上，夏季的細菌數量最多，其次分別為春、秋、冬各季；在土壤中降解氧樂果的細菌數量上，夏季土壤中的降解菌株數量也最多，其次分別為春、秋、冬各季，土壤磷的含量與降解氧樂果細菌的數量之間並沒有太大的相關性（ r = 0 . 494 ） ；在降解菌占細菌總數百分比上，秋季降解菌株所佔百分比最大，為0 . 547 % ；在降解菌株中，芽孢桿菌屬（ bacillus ）在每一季節所佔的比例都是最大的，春、夏、秋、冬分別為44 . 44 % 、 50 . 00 % 、 48 . 15 % 、 47 . 22 % ，其它菌屬所佔比例都比較少，這可能跟土壤的基本性狀有關，春夏秋冬四季的輪換，氣溫的變化，植被的差異，耕作的不同，比較適合抗逆性較強的芽孢桿菌屬（ bacillus ）的生長。The diaphragm had the ability to detect the positive serum when it was diluted to 2 ' 11 and so it has good sensitivity ; stored at 4 for at least 7 months, the sensitivity and specificity of the diaphragm did not change, so it has good stability ; when 10 positive serum was detected 3 times, the result is reproducible, so the diaphragm has good reproducible. serums from experimental inoculated piglets was detected. the results showed that when the titer is l : 16, the pigs were infected with streptococcus suis ; and when 1 : 64, the pigs could survive after challege with streptococcus suis. all the results have shown that dot - ppa - elisa was a convenient, rapid, sensitive specific useful method for the detection of antibody
