  • Legionnaires' Disease, Pontiac Fever, Legionellosis and Legionella
    Legionnaires’ Disease, Pontiac Fever, Legionellosis and Legionella Q: What is Legionellosis and who is at risk? Legionellosis is an infection caused by Legionella bacteria. Legionellosis can present as two distinct illnesses: Pontiac fever (a self-limited flu-like mild respiratory illness), and Legionnaires’ Disease (a more severe illness involving pneumonia). People of any age can get Legionellosis, but the disease occurs most frequently in persons over 50 years of age. The disease most often affects those who smoke heavily, have chronic lung disease, or have underlying medical conditions that lower their immune system, such as diabetes, cancer, or renal dysfunction. Persons taking certain drugs that lower their immune system, such as steroids, have an increased risk of being affected by Legionellosis. Many people may be infected with Legionella bacteria without developing any symptoms, and others may be treated without having to be hospitalized. Q: What is Legionella? Legionella bacteria are found naturally in freshwater environments such as creeks, ponds and lakes, as well as manmade structures such as plumbing systems and cooling towers. Legionella can multiply in warm water (77°F to 113°F). Legionella pneumophila is responsible for over 90 percent of Legionnaires’ Disease cases and several different species of Legionella are responsible for Pontiac Fever. Q: How is Legionella spread and how does someone acquire Legionellosis (Legionnaires’ Disease/Pontiac Fever)? Legionella bacteria become a health concern when they grow and spread in manmade structures such as plumbing systems, hot water tanks, cooling towers, hot tubs, decorative fountains, showers and faucets. Legionellosis is acquired after inhaling mists from a contaminated water source containing Legionella bacteria.

Determine what education needs are available. 2 WHAT ARE "EMERGING" INFECTIOUS DISEASES? Infectious diseases whose incidence in humans has increased in the past two decades or threatens to increase in the near future have been defined as "emerging." These diseases, which respect no national boundaries, include: • New infections resulting from changes or evolution of existing organisms • Known infections spreading to new geographic areas or populations • Previously unrecognized infections appearing in areas undergoing ecologic transformation 3 1 12/2/2015 WHAT ARE RE-EMERGING INFECTIOUS DISEASES? Any condition, usually an infection, that had decreased in incidence in the global population and was brought under control through effective health care policy and improved living conditions, reached a nadir, and, more recently, began to resurge as a health problem due to changes in the health status of a susceptible population. 4 REPORTABLE CONDITIONS 5 CDC’S LIST OF EIDS • malaria • drug-resistant infections (antimicrobial resistance) • Marburg hemorrhagic fever • bovine spongiform encephalopathy (Mad cow disease) & variant Creutzfeldt-Jakob disease (vCJD) • measles • campylobacteriosis • meningitis • Chagas disease • monkeypox • cholera • MRSA (Methicillin Resistant

Weir 1,2,* 1 Division of Environmental Health Sciences, College of Public Health, The Ohio State University, Columbus, OH 43210, USA; [email protected] 2 Risk Modeling Division, Applied Research Center, NSF International, Ann Arbor, MI 48105, USA * Correspondence: [email protected]; Tel.: +1-614-292-4066 Received: 16 December 2017; Accepted: 29 January 2018; Published: 31 January 2018 Abstract: Legionella pneumophila (L. pneumophila) is an infectious disease agent of increasing concern due to its ability to cause Legionnaires’ Disease, a severe community pneumonia, and the difficulty in controlling it within water systems. L. pneumophila thrives within the biofilm of premise plumbing systems, utilizing protozoan hosts for protection from disinfectants and other environmental stressors. While there is a great deal of information regarding how L. pneumophila interacts with protozoa and human macrophages (host for human infection), the ability to use this data in a model to attempt to predict a concentration of L. pneumophila in a water system is not known. The lifecycle of L. pneumophila within host cells involves three processes: uptake, growth, and egression from the host cell. The complexity of these three processes would risk conflation of the concepts; therefore, this review details the available information regarding how L. pneumophila invades host cells (uptake) within the context of data needed to model this process, while a second review will focus on growth and egression. The overall intent of both reviews is to detail how the steps in L.

  • EVALUATION of the P45 MOBILE INTEGRATIVE ELEMENT and ITS ROLE IN
    EVALUATION OF THE p45 MOBILE INTEGRATIVE ELEMENT AND ITS ROLE IN Legionella pneumophila VIRULENCE A Dissertation by LANETTE M. CHRISTENSEN Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Jeffrey D. Cirillo Committee Members, James Samuel Jon Skare Farida Sohrabji Head of Program, Warren Zimmer May 2018 Major Subject: Medical Sciences Copyright 2018 Lanette Christensen ABSTRACT Legionella pneumophila are aqueous environmental bacilli that live within protozoal species and cause a potentially fatal form of pneumonia called Legionnaires’ disease. Not all L. pneumophila strains have the same capacity to cause disease in humans. The majority of strains that cause clinically relevant Legionnaires’ disease harbor the p45 mobile integrative genomic element. Contribution of the p45 element to L. pneumophila virulence and ability to withstand environmental stress were addressed in this study. The L. pneumophila Philadelphia-1 (Phil-1) mobile integrative element, p45, was transferred into the attenuated strain Lp01 via conjugation, designating p45 an integrative conjugative element (ICE). The resulting trans-conjugate, Lp01+p45, was compared with strains Phil-1 and Lp01 to assess p45 in virulence using a guinea pig model infected via aerosol. The p45 element partially recovered the loss of virulence in Lp01 compared to that of Phil-1 evident in morbidity, mortality, and bacterial burden in the lungs at the time of death. This phenotype was accompanied by enhanced expression of type II interferon in the lungs and spleens 48 hours after infection, independent of bacterial burden.
