笔者于１９７５～１９８９年对我国南方琼、粤、桂、湘四省区不同纬度的１３个县市进行类鼻疽菌分离，从１０个县市的水样品和人、畜病理标本中共获得７３株类鼻疽假单胞菌。血清学调查发现抗体阳性率与病菌的分布呈相关关系。井证实疫源地分布于粤、桂、琼的南亚热带和边缘热带地区。疫区人群抗体阳性率为３．８％～１５．２％，马为９．１％～１８．４％，牛为６．６％～３３．０％，感染猪群阳性率高达３５．０％，屠宰猪标本分离率为１３％。类鼻疽的危害调查表明，马、骡感染后会干扰鼻疽检疫。病菌污染肉品，危害公共卫生。在１９８９年９至１０月份的一次临床病例调查中，在湛江和海南三亚发现３例患者，２例因败血症死亡，１例为慢性下肢溃疡，可能还有显性感染患者被漏诊或误诊．
From 1975 to 1989, the author isolated 13 kinds of gonorrhea bacteria from 13 counties in different latitudes in the four provinces of Joan, Kwak, Kwang and Xiang in South China. From the water samples of 10 counties and cities and pathological specimens of humans and animals, Pseudomonas. Serological survey found that antibody positive rate and the distribution of bacteria are related. Well confirmed foci distributed in Guangdong, Guangxi, Joan of the South subtropical and tropical edge areas. The positive rate of antibody in the infected area was 3.8% -15.2%, that of horses was 9.1% -18.4%, that of cattle was 6.6% -33.0%, and that of infected pigs was as high as 35.0 %, Slaughter pig specimens separation rate of 13%. An investigation of the dangers of glanders shows that horses and mules interferes with the diagnosis of glanders after infection. Bacteria contaminate meat products, endanger public health. In a clinical case survey from September to October 1989, three patients were found in Zhanjiang and Sanya, Hainan Province. Two died of septicemia, one was chronic leg ulcers and possibly a dominant infection was missed or misdiagnosed.
