目的了解西安市不同生境德国小蠊体表带菌状况,提高对蟑螂危害的防范意识,为预防控制以蟑螂为媒介生物性传染病的传播流行提供科学依据。方法依据2002年版《消毒技术规范》所规定的方法分别对细菌总数、大肠杆菌、霉菌、沙门氏菌、志贺氏菌、金黄色葡萄球菌、铜绿假单胞菌、溶血性链球菌和粘质沙雷氏菌9个项目进行了检测。结果不同生境德国小蠊体表带菌检出率为100%,其中霉菌检出率最高为100%;依次是大肠杆菌检出率为80%、铜绿假单胞菌和粘质沙雷氏菌检出率均为40%、金黄色葡萄球菌和沙门氏菌检出率均为20%;志贺氏菌和溶血性链球菌检出率最低,均未检出。结论西安市德国小蠊体表带菌状况较为严重,存在相关媒介生物性疾病传播风险较高,应不断加强蟑螂的监测和防治力度。
Objective To understand the status of surface bacteria in German cockroach in different habitats in Xi’an and to improve the prevention awareness of cockroach hazards and provide a scientific basis for the prevention and control of the spread of infectious diseases caused by cockroaches. Methods The total number of bacteria, Escherichia coli, mold, Salmonella, Shigella, Staphylococcus aureus, Pseudomonas aeruginosa, hemolytic streptococcus and mucilaginous were determined respectively according to the methods of Disinfection Technical Code of 2002, 9 strains of bacteria were tested. Results The detection rate of body surface bacteria in German cockroach was 100% in different habitats, the highest detection rate of mold was 100%. The detection rate of Escherichia coli was 80%, Pseudomonas aeruginosa and Serratia marcescens The rates were 40%, Staphylococcus aureus and Salmonella were detected 20%; Shigella and hemolytic streptococcus detection rate was the lowest, were not detected. Conclusion The prevalence of surface bacteria in the cockroaches in Xi’an is more serious and there is a higher risk of transmission of related vector biological diseases. The monitoring and prevention of cockroaches should be strengthened.
