中文摘要：在不同温度下 ,对南美白对虾 (Penaeusvannamei)肠道乳酸杆菌(Lactobacillussp.)、双歧杆菌(Bifidobactsp.)、大肠杆菌(Escherichiacoli)、金黄色葡萄球菌(Staphylococcusaureus)、副溶血性弧菌(Vibrioparahaemolyticus)、产气荚膜梭菌产气荚膜梭菌(Clostridiumperfringens)、厌氧菌总数和好氧菌总数进行了定性定量分析。结果表明 ,大肠杆菌、金黄色葡萄球菌、副溶血性弧菌、产气荚膜梭菌为过路菌群 ;乳酸杆菌、双歧杆菌为常住菌群。厌氧菌总数、双歧杆菌随水温升高显著增加 (Ftest,P<0.01) ;好氧菌总数、乳酸杆菌随水温升高变化不显著(Ftest,P>0.05)。肠道中厌氧菌总数比好氧菌多(ttest,P<0.05) ,且随着水温升高 ,厌氧菌的优势越明显。

外文摘要：This paper considers the influence of water temperature on the intestinal microflora of Penaeus vannamei.Six types of bacteria Escherichia coli,Lactobacillus sp..,Bifidobacteriub sp.,Staphylococcus aureus,Vibrio paraˉhaemolyticus,Clostridium perfringens,the total number of anaroe and the total number of aerobe were investigated both qualitatively and quantitatively under different water temperatures.Results show lactobaccillus and bifihaemolyticas are present at all tested temperatures while Escherichia coli,Staphyloccus aureus,Clostridium perfringens,Vibrio paraˉhaemolyticus are sometimes present.Total number of anaroe changes remarkably(F test,P<0.01)at different temperaˉtures,and so does bifidobacteriub.Despite temperature changes(F test,P>0.05)no significant changes are seen in total number of aerobe and lactobacillus present.Total number of anaerobe in the intestine is much greater than that of aerobe(t test,P<0.05),this difference becomes marked as temperature increases.
