Highly-pathogenic avian influenza virus (HPAIV H5N1) poses risks to wild birds, poultry, and humans. Personnel with the United States Department of Agriculture-Animal Plant Health Inspection Service-Wildlife Services, state, and tribal wildlife agencies collected 168,940 samples from migratory birds from 2007 to 2009 to test for presence of HPAIV H5N1. No HPAIV was found, but other subtypes were discovered, including H5 and H7. I estimated prevalence of avian influenza virus by flyway and found prevalence was lowest each year in the Atlantic Flyway (6.7%–8.3%), highest in the Pacific Flyway in 2007 (13.3%) and 2008 (13.4%), and highest in the Mississippi Flyway …

Bovine tuberculosis (TB) was responsible for more losses among U.S. farm animals in the early 20th century than all other infectious diseases combined. The Cooperative State-Federal Tuberculosis Eradication Program (established in 1917 and administered by APHIS, State animal health agencies, and U.S. livestock producers) has nearly eradicated bovine TB from the nation’s livestock population. However, despite the many accomplishments of the program, bovine TB remains a serious and costly disease of livestock in the United States. In 1992, VS conducted an assessment to identify pathways for the introduction and spread of bovine TB, in order to develop the most effective …


Fascin1 Promotes Cell Migration Of Mature Dendritic Cells, Michael Lipscomb Feb 2011

Fascin1 Promotes Cell Migration Of Mature Dendritic Cells, Michael Lipscomb

Department of Biology Faculty Publications

Dendritic cells (DCs) play central roles in innate and adaptive immunity. Upon maturation, DCs assemble numerous veil-like membrane protrusions, disassemble podosomes, and travel from the peripheral tissues to lymph nodes to present Ags to T cells. These alterations in morphology and motility are closely linked to the primary function of DCs, Ag presentation. However, it is unclear how and what cytoskeletal proteins control maturation-associated alterations, in particular, the change in cell migration. Fascin1, an actin-bundling protein, is specifically and greatly induced upon maturation, suggesting a unique role for fascin1 in mature DCs. To determine the physiological roles of fascin1, we …


Some Laelapine Mites (Acari: Laelapidae) Ectoparasitic On Small Mammals In The Galapagos Islands, Including A New Species Of Gigantolaelaps From Aegialomys Galapagoensis, Donald D. Gettinger, Fernanda Martins-Hatano, Scott Lyell Gardner Jan 2011

Some Laelapine Mites (Acari: Laelapidae) Ectoparasitic On Small Mammals In The Galapagos Islands, Including A New Species Of Gigantolaelaps From Aegialomys Galapagoensis, Donald D. Gettinger, Fernanda Martins-Hatano, Scott Lyell Gardner

Scott L. Gardner Publications

A collection of laelapine mites from small mammals in the Galapagos Islands are identified and their host distributions reviewed. Two species of native rodents, Aegialomys galapagoensis and Nesoryzomys narboroughii, were infested only with species typical of Neotropical oryzomyine rodents; Rattus rattus was infested with Laelaps nuttalli, a host-specific ectoparasite to Old World Rattus. A synopsis of Gigantolaelaps Fonseca is provided and we describe a new laelapine mite, Gigantolaelaps aegialomys n. sp., from the pelage of the rodent A. galapagoensis on Santa Fe Island. The new species has strong morphological affinities with a subgroup of Gigantolaelaps associated with …
