Ehrlichiosis: Understanding immune mechanisms that lead to the development of fatal disease
… I depleted NK cells the mouse model of fatal ehrlichiosis. Most strikingly, depletion of NK cells resulted in much less pathology including significantly lower systemic levels of cytokines, lower ehrlichial burdens, and minimal liver injury when compared to control mice. My data provide …

Host-Dependent Expression, Transcriptional Regulation and Protection of Ehrlichia chaffeensis Tandem Repeat Proteins
… is the causative agent of human monocytotropic ehrlichiosis, an emerging life-threatening zoonosis. E. chaffeensis is transmitted by the lone star tick, Amblyomma americanum, and replicates in mononuclear phagocytes in mammalian hosts. The major immunoreactive proteins of E. chaffeensis include …

A Molecular Survey of Ehrlichia Chaffeensis and Ehrlichia Ewingii in Dogs and Ticks From Southwest Missouri
Ehrlichiosis is a newly recognized human disease that is caused by bacteria of the genus Ehrlichia. Previous studies have suggested that dogs may serve as reservoirs for some species of Ehrlichia. Nested-PCR was used to survey for the presence of Ehrlichia chaffeensis and Ehrlichia ewingii in blood …

Elucidating the Molecular Function of Reprolysin Metalloproteases in Tick-Host-Pathogen Interaction
… the causative agent of Human Monocyte Ehrlichiosis. This experiment consisted of two main goals: the first was to characterize <em>A. americanum</em> Reprolysin Metalloproteases, and the second to gain a better insight into the relationship between this tick and <em>E. chaffeensis</em>, …

Tick Infestations and Their Consequences for Migratory Songbirds During Spring Stopover
… causative agent of the tickborne disease ehrlichiosis, to determine if ticks and their associated pathogens are capable of being transported to North America by way of migrating birds. We found that 27 (10.2%) of 252 blood samples were positive for <em>E. chaffeensis</em> and 109 (97.3%) …

The role of the P28 multigene family in the pathogenesis of Ehrlichia chaffeensis infection.
… the emerging infectious disease, human monocytic ehrlichiosis (HME), a potentially fatal illness. Although easily treated with tetracycline, due to its obligate intracellular parasitism it is difficult to diagnose by routine clinical methods. <i>E. chaffeensis</i> expresses a 28 kDa outer membrane …

The Prevalence of Human Granulocytic Ehrlichiae in <em>Ixodes scapularis</em> Ticks in Southeastern Georgia
<p>Human granulocytic ehrlichiosis (HGE) is a newly emerging, tick-borne zoonosis in North America. The agent that causes HGE is very similar to <em>Ehrlichia</em> <em>phagocytophilia</em> and <em>Ehrlichia</em> <em>equi</em>, but has yet to be classified as a separate species.</p> <p>This study …

Ehrlichia chaffeensis mediates Hedgehog and Hippo signaling to activate an anti-apoptotic cellular program
… the emerging zoonotic disease, human monocytic ehrlichiosis (HME). HME is the most prevalent and life-threatening tick-borne disease in the United States. In the past two decades, the incidence of HME has increased 10-fold; however, the number of reported cases is underestimated by 100-fold due …

Tick abundance and microorganism diversity in the 11 counties comprising the Choctaw Nation of Oklahoma
… rates of Spotted Fever Rickettsiosis and Ehrlichiosis within humans in the United States. However, the lack of localized surveys of tick vectors in the region have left gaps in our understanding of these diseases in the region. This study attempts to define the current distribution and …

Determining the Prevalence and Distribution of Tick-Borne Pathogens in Southeastern Virginia and Exploring the Transmission Dynamics of Rickettsia Parkeri in Amblyomma Maculatum
… of Lyme disease, spotted fever rickettsioses, ehrlichiosis and anaplasmosis are on the rise. Factors related to emergence include appearance of a new pathogen, recognition of an existing pathogen and environmental changes that result in new exposure events. Despite the rise in tick-borne …

A farm-based prospective study for equine colic risk factors and risk associated events
… OR=6.3(1.8-22)); and vaccination with monocytic ehrlichiosis vaccine during the study, OR=2.0(1.8-22). Feeding whole grain with or without other concentrates had less risk than diets without whole grain included. Variables related to concentrate feeding frequency or concentrate type could be …

The Lyme Disease Spirochete, <i>Borrelia burgdorferi</i>, in Tick Species Collected from Raccoons (<i>Procyon lotor</i>) and Opossums (<i>Didelphis virginiana</i>) Trapped in the Warren and Barren Counties of South Central Kentucky
The incidence of tick-borne zoonoses such as Ehrlichiosis, Rocky Mountain Spotted Fever, and Lyme disease has steadily increased in the southeastern United States in recent years. According to the Centers for Disease Control and Prevention (CDC), the southeastern states accounted for 1,200 of the …

Ehrlichia chaffeensis Activates Notch Signaling Through SLiM Mimicry to Inhibit Apoptosis
… the etiological agent of human monocytotropic ehrlichiosis (HME), an emerging, life threatening tick-borne zoonosis. E. chaffeensis infects mononuclear phagocytes and has evolved molecular strategies to reprogram the host cell involving secreted effectors that interact directly with the host …
