Pleiotropic Effect of tatC Mutation on Metabolism of Pathogen yersinia enterocolitica

引用

Biomedical and Environmental Sciences 2007年第6期20卷 445-449页

作者： ZHI-YANG SHI HUA WANG LING GU ZHI-GANG CUI LONG-FEI WU BIAO KAN BO PANG XIN WANG JIAN-GUO XU HUAI-QI JING Jiangsu Provincial Center for Diseases Control and Prevention Nanjing 210009 Jiangsu China State Key Laboratory for Infectious Disease Prevention and Control National Institute of Communicable Diseases Prevention and Control Chinese Center for Diseases Control and Prevention Beijing 102206 China Laboratoire de Chimie Bacterienne IBSM CNRS Marseille F-13402 France

Objective To analyze the impact of depletion of the twin arginine translocation （TAT） system on virulence and physiology of yersinia enterocolitica for a better understanding of its pathogenicity. Methods We constructed a △tatC：：Sp^R mutant of yersinia enterocolitica by P1 phage mediated transduction using Escherichia coli K-12 △tatC：：Sp^R strain as a donor. Results A Pl-mediated genetic material transfer was found between the two species of enterobacteria, indicating a great potential of acquisition of antibiotic resistance in emergency of a new threatening pathogen by genetic material exchanges. Periplasmic trimethylamine N-oxidase reductase activity was detected in the wild type E enterocolitica strain and translocation of this enzyme was completely abolished by the △tatC：：Sp^R mutation. In addition, the △tatC：：Sp^R mutation showed a pleiotropic effect on the metabolism of E enterocolitica. However, the tat mutation did not seem to affect the mobility and virulence of Y. enterocolitica under the conditions used. Conclusion Unlike other pathogenic bacteria studied, the TAT system of E enterocolitica might play an important role in the pathogenic process, which is distinct from other pathogens, such as Pseudomonas aeruginosa and enterohemorrhagic E. coli O 157：H7.

yersinia enterocolitica Infection of a Prosthetic Knee *** Report and Review of the Literature on Deep Sited Infections Caused by ***

Advances in Infectious Diseases 2013年第2期3卷 95-99页

作者： Paivi Jalava-Karvinen Jarmo Oksi Kaisu Rantakokko-Jalava Petri Virolainen Pirkko Kotilainen Department of Infectious Diseases Division of MedicineTurku University HospitalTurkuFinland Faculty of Medicine Turku UniversityTurkuFinland Clinical Microbiology Laboratory TurkuFinland Department of Orthopedics and Traumatology Turku University HospitalTurkuFinland

Prosthetic joint infection is a rare manifestation of yersinia enterocolitica. We report a case of a patient presenting with fever and a purulent infection in his prosthetic knee joint caused by Y. enterocolitica. He had been operated in 1990 for arthrosis of the right knee. Re-operation was performed in 2007 for loosening of the prosthesis. Seven months later, following progressively increasing knee pain, he became acutely febrile and a purulent knee joint infection was diagnosed. Y. enterocolitica was isolated from the joint fluid. Serum antibodies against Y. enterocolitica were also positive. He was treated with debridement, replacement of the liner component of the prosthesis and a long course of intravenous antimicrobial therapy. The infection was thought to be in a chronic suppressive state. The final outcome after all therapy was good.

Isolation and Pathogenicity Analyses on yersinia enterocolitica from Pelteobagrus vachelli

引用

Journal of Northeast Agricultural University(English Edition) 2015年第2期22卷 29-35,F0003页

作者： Zhao Jing Wang Li College of Life Science and Technology Southwest University for Nationalities

yersinia enterocolitica is an important zoonotic pathogen that can induce disease outbreaks in a wide host range. Strain YER6022 was isolated from Pelteobagrus vachelli and identified using bacterial morphology and 16S rDNA sequence analysis. Five virulence factors were detected, then artificial infection experiment and histopathological method were carried out. These results showed that strain YER6022 was one of Y. enterocolitica family members. In addition, ail, ystb, virF, yadA and HPIint were dectected. In artificial infection experiment, with 80% mortality and 100% morbidity, injected Pelteobagrus vachellis showed red swollen of the anus, abdomen swelling and fim bleeding. There existed serious hyperaemia and edema in kidney, spleen, intestine and liver at the light microscope. Ultrastructural observation indicated that mitochondria of the liver, kidney, spleen and intestine swelled and mitochondrial cristae broke. The data had further shed light on its pathogenicity in Pelteobagrus vachelli. It would benefit for further studies on pathogenesis ofPelteobagrus vachelli infected with Y. enterocolitica.

为检验131例生牛奶中大肠耶新氏杆菌的存在,使用了四种增菌法。所获得的42株菌来自19个混合样品(其中31.1％为阳性)和10个个体生产者的样品(其中14.3％为阳性)。用巴特菲尔德磷酸缓冲液培养子4℃14天,然后接种到改良的Rappaport肉汤,继续培养在23℃下5天,产生最大数量的分离物。绝大多数的分离菌属于生物型第1型,临床分离的许多菌株为不典型的,它们是鼠李糖阳性(47.6％)、柠檬酸盐阳性(16.1％)。乳糖阳性(26.2％)。十三株细菌可以血清学方法分型,属于7种不同的O血清型,0∶5居多数。(作者摘要) 注:近来,大肠耶新氏杆菌主要作为人的新的感染症的病原菌正为人们所注意。译者引自陈昭奕同志《畜牧兽医》文摘号78.811号。
