Clinical characteristics of a severe bubionic plague patient / 中华地方病学杂志

Objective:To understand the clinical manifestations and prognosis of severe bubonic plague, and to explore the treatment experience of severe bubonic plague.Methods:A retrospective analysis was conducted on the clinical data and treatment of a case of severe bubonic plague admitted to Huade County on November 11, 2019.Results:The case of bubonic plague was a 55-year-old male, and outbreak after hunting the hare at the foci. The clinical manifestations included fever, fatigue, left armpit skin hard, swelling, heat and pain, distinctness of lymph node enlargement in later stage, hiccups and pleural effusion. Laboratory tests showed diffuse intravascular coagulation (DIC), sepsis and multiple organ dysfunctions. Bubonic plague was confirmed by positive culture of Yersinia pestis and positive phage lysis test on the 3rd day after admission. After platelet, plasma, fluid resuscitation and streptomycin combined with moxixacin, DIC and multiple organ functions were restored to normal and the hard swelling subsided. The course of treatment lasted for 19 days, the body temperature returned to normal and the patient recovered. Conclusions:This patient is a severe case of bubonic plague characterized with lymphangitis, skin sclerosis and abnormal coagulation. Timely identification, evaluation, early and combined treatment is the key to successful treatment.

Analysis of a monitoring results on animal plague in Meriones unguiculatus plague natural foci in Inner Mongolia from 2010 to 2014 / 中华地方病学杂志

Objective To analyze the monitoring results on plague in Meriones unguiculatus plague natural foci in Inner Mongolia from 2010 to 2014,to master the epidemic dynamics of the plague and to provide a basis for developing countermeasures.Methods The plague monitoring data in Meriones unguiculatus plague natural foci from 2010 to 2014 were collected;main host density,rate of dye fleas,flea body index and bacteriology were counted;serology detection was done and the epidemic situation was analyzed.Isolation and identification of Yersinia pestis were carried out through a 4-step test (microscopic examination,isolation and culture,phage lysis test and animal experiment).Serum samples were tested by indirect hemagglutination test.Results Within 5 years,21689 Meriones unguiculatus were captured overlap monitored areas of 7116 hm2 totally,the average rat density was 3.05/hm2;other small rodents were clipped 144352 times,3947 mice were captured,capture rate was 2.73％.Totally 26500 Meriones unguiculatus were checked,91 Meriones unguiculatus were infected with epidemic diseases,227 of 59 groups positive fleas were checked from cultured 51262 fleas of 13268 groups.Totally 5426 serum samples of Meriones unguiculatus were checked,5 copies were found positive,the positive rate was 0.09％.Conclusions Inner Mongolia Meriones unguiculatus plague is still active and spreading.We must enhance propaganda of the plague.Surveillance and emergency management should be strengthened to prevent a outbreak of the plague in human being.

Analysis of monitoring results on plague of rats in Lasiopodomys brandti plague natural foci in Inner Mongolia from 2001 to 2013 / 中华地方病学杂志

Objective To analysis the plague monitoring results on plague of rats in Lasiopodomys brandti plague natural foci of Xilin Gol Plateau in Inner Mongolia from 2001 to 2013,to master the dynamics of the plague epidemic,and to provide a basis for developing countermeasures.Methods Plague monitoring data from 2001 to 2013 in Lasiopodomys brandti plague natural foci were collected,main host density,rate of dye fleas,flea body index,bacteriology,serology and epidemic situation were studied.Results Within 13 years,10 153 Lasiopodomys brandti were captured overlapping a monitored area of 2 919.25 hm2,the average rat density was 3.48/hm2;other small rodents were captured 43 632 times,and 1 631 mice were captured,capture rate was 3.74％.Totally 22 752 host animals were checked by etiology,104 animals were infected with epidemic diseases,79 fleas of 31 groups positive fleas were checked from cultured 27 702 fleas of 6 437 groups.Totally 2 237 serum samples of Lasiopodomys brandti were checked using indirect hemagglutination (IHA),2 copies were found positive,the positive rate was 0.09％.Conclusion In Lasiopodomys brandti plague natural foci of Inner Mongolia,the plague bacteria infected host animals are still existed,future outbreak is possible;the monitoring and health education should be strengthened,in order to prevent the plague spreading to human being.
