Diagnosis of Bovine Anaplasmosis Using Anaplasma Antigenic Markers Identified by Western Blotting
Diagnosis of bovine anaplasmosis relies on serology using crude parasite extracts, detection of parasitemia, or subinoculation of blood from suspected animals into susceptible animals. Anaplasma can not be cultured in vitro. The feasibility of using antigenic markers detected by Western blotting …

THE ROLE OF OUTER MEMBRANE PROTEIN A IN ANAPLASMA MARGINALE CELLULAR INVASION AND ITS POTENTIAL AS A CROSS-PROTECTIVE ANTIGEN
… are the etiologic agents of human granulocytic anaplasmosis and bovine anaplasmosis, respectively. Both diseases can be severe, even fatal, and protective vaccines for each are lacking. We recently identified A. phagocytophilum outer membrane protein A (ApOmpA) as being critical for cellular …

Seroprevalence of Anaplasma phagocytophilum in the equine population of Southwest Virginia
Background: Equine granulocytic anaplasmosis (EGA), caused by the organism Anaplasma phagocytophilum, is a tick-borne disease of clinical importance in Southwest Virginia. The disease is recognized worldwide and causes pyrexia, anorexia, limb edema, and lethargy. Diagnosis in endemic areas is often …

<i>Ixodes Scapularis</i> SRC Kinase Is Required for Rickettsial Pathogen Survival in Ticks
… and animals. It is the causative agent for human anaplasmosis. <em>A. phagocytophilum</em> uses certain strategies to infect both vertebrates and invertebrates. It uses<em> Ixodes scapularis</em> ticks as a vector for spreading infection to other mammal species. This bacterium has a specific path …

Ticks And Tick-Borne Pathogens In North Dakota
… phagocytophilum (agent of human granulocytic anaplasmosis), and Babesia microti (agent of human babesiosis). Of those tested, A. phagocytophilum was detected in 8.5%, B. burgdorferi was detected in 3.3%, and B. microti was not detected. These are the first reports of A. phagocytophilum and B. …

Determining the Prevalence and Distribution of Tick-Borne Pathogens in Southeastern Virginia and Exploring the Transmission Dynamics of Rickettsia Parkeri in Amblyomma Maculatum
… 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 disease incidence …

APPROACHES TO IDENTIFY SURFACE PROTEINS OF ANAPLASMA PHAGOCYTOPHILUM DENSE-CORED ORGANISMS AS ADHESINS TO HUMAN P-SELECTIN GLYCOPROTEIN LIGAND-1
… infects neutrophils to cause human granulocytic anaplasmosis. Sialyl Lewis x (sLex)-modified P-selectin glycoprotein ligand-1 (PSGL-1) is the confirmed receptor utilized by A. phagocytophilum to bind and invade human neutrophils and myeloid cell lines. As an obligate intracellular pathogen, the …

Anaplasma phagocytophilum remodels its host cell-derived vacuole into a protective niche by redecorating the vacuolar membrane with select Rab GTPases and bacterial proteins
… tick-transmitted disease, human granulocytic anaplasmosis (HGA). Following entry, the pathogen replicates within a host cell-derived vacuole that fails to mature along the endocytic pathway, does not acidify, and does not fuse with lysosomes. Selective fusogenicity is prototypical of many …
