从我国不同地区的147头家居蜚蠊中分离获得562株细菌分属于13个属，其优势菌群属于埃希氏菌属、芽抱杆菌属、短杆菌属共422株菌，占总菌数的75．09％；其次为沙雷氏菌属、假单胞菌属共85株，占总数的15．12％；其他8个属仅43株菌，占总数的9．25％。比较了德国小蠊、美洲大蠊和黑胸大蠊及它们的体表、体腔、中肠和粪便所携带的细菌类群和数量，其结果有很大差异。该文讨论了蜚蠊细菌与人类疾病之间的关系。
562 strains isolated from 147 domestic cockroaches in different regions of China belonged to 13 genera, and the dominant bacteria belonged to 422 strains of Escherichia, Bacillus, and Brevibacterium, accounting for the total number of bacteria Of the total, accounting for 75.09%; followed by Serratia, Pseudomonas, a total of 85, accounting for 15.12% of the total; other 8 genera and 43 strains, accounting for 9.25% of the total. Comparing the populations and numbers of bacteria carried by Blattella germanica, Periplaneta americana and Blattella germanica and their body surfaces, body cavities, midgut and feces, the results vary widely. This article discusses the relationship between cockroach bacteria and human diseases.
