    摘要: A strain of Francisella species wherein a gene which encodes for part of the glutamate metabolic pathway has been inactivated, and which is able to produce a protective immune response in an animal, for use as live prophylactic or therapeutic vaccine against infection by said Francisella species. Particularly effective strains include those where the capB gene is deleted. Other embodiments of the invention describe strains which comprise a further genetic mutation wherein a gene which encodes for another component of the cell is also inactivated. Pharmaceutical compositions comprising said strains, together with methods which utilise such strains are also described and claimed.

    摘要: Francisella tularensis is the bacterial pathogen that causes tularemia in humans and a number of animals. To date, no approved vaccine exists for this widespread and life-threatening disease. The present disclosure provides attenuated Francisella mutants that include genetic inactivations in two genes. The Francisella mutants contain a genetic inactivation in at least one gene selected from dsbB, FTT0742, pdpB,fumA, and carB, and at least one gene selected from tolB, htrB, ipxH, ostAl, fimT, ipcC, manB, manC, nusA, wzx, kdtA, FTN0408, FTN0757 and FTN1254. Also provided are immunogenic compositions that include the attenuated bacteria. Methods are provided for treatment (e.g., treatment of tularemia) using the attenuated Francisella mutants.

    摘要: A polypeptide comprising at least one component of an Hsp60 obtainable from Francisella tularensis, and in particular the GroEL protein, or a fragment thereof, or a variant of any of these, which polypeptide, when administered to an animal, produces an immune response which is protective against F. tularensis infection, for use in prophylactic or therapeutic vaccination against F. tularensis. The polypeptide may be administered directly to the host, or nucleic acid encoding the polypeptide may be administered in a form in which they might be expressed in vivo. Vaccines based upon these polypeptides suitably include an additional component and in particular an adjuvant which promotes a cellular immune response.

    摘要: Establishment of an effective and uniform vaccine development strategy is key to conquering current and emerging infectious diseases. Despite successes against an array of bacterial agents, current approaches to vaccine development are as diverse as the microbes they target and require adjuvants that often have limited efficacy and/or toxic side effects. As a consequence, vaccine discovery is often slow, inefficient, and unsuccessful in the case of many high priority pathogens. The present disclosure suggests that vaccine generation for bacterial pathogens can be improved by optimizing the efficiency of processing/presentation of a bacterial immunogen via the targeting of immunogen to CR2 and/or TLR2 on APCs. This approach not only yields an adjuvant-free mucosal vaccine against a Category A biothreat agent, but also establishes a novel genetic approach/platform for vaccine development, which is applicable to many other infectious agents, thereby profoundly impacting preventive medicine/public health.

    摘要翻译: 制定有效和统一的疫苗发展战略是征服目前和新出现的传染病的关键。 尽管针对一系列细菌试剂取得了成功,但目前疫苗开发的方法与其目标的微生物一样多,并且需要通常具有有限功效和/或毒性副作用的佐剂。 因此,在许多高优先级病原体的情况下,疫苗发现通常是缓慢,低效率和不成功的。 本公开内容表明,通过在APC上通过将免疫原靶向CR2和/或TLR2来优化处理/呈递细菌免疫原的效率,可以改善细菌病原体的疫苗产生。 这种方法不仅产生针对A类生物降解剂的无佐剂的粘膜疫苗,而且建立了疫苗开发的新型遗传方法/平台,适用于许多其他感染因子,从而深刻影响预防医学/公共卫生。
