The role of excreted antibiotics in the establishment of persistent on-farm reservoirs of antibiotic-resistant bacteria
Bioavailable antibiotic residues from treated animals likely contribute to the persistence of antibiotic-resistant bacteria in agricultural systems. To determine the magnitude of this effect, we evaluated changes in the ...
COMPARATIVE INVESTIGATION OF THE IMMUNE SYSTEMS OF TWO OVINE SPECIES (OVIS ARIES AND OVIS CANADENSIS)
Chapter 1 describes the economic and ecologic significance of respiratory disease in domestic sheep (DS; Ovis aries) and bighorn sheep (BHS; Ovis canadensis) and the need for interspecies comparative immune analyses. In ...
IMMUNIZATION STRATEGIES FOR THE CONTROL OF MANNHEIMIA HAEMOLYTICA PNEUMONIA IN BIGHORN SHEEP
Mannheimia haemolytica is an important pathogen of pneumonia in bighorn sheep (BHS, Ovis canadensis). Leukotoxin is the critical virulence factor of this bacterium. In an earlier study, an experimental vaccine containing ...
FUNCTIONAL CHARACTERIZATION OF THE BACTERIAL MICROBIOME OF THE DERMACENTOR ANDERSONI TICK EXHIBITS INTERACTIONS WITH PATHOGEN ACQUISITION
Ticks are obligate hematophagous arthropods that feed on vertebrates and are of importance due to their ability to inflict harm to humans and animals. In particular, ticks transmit pathogens throughout all continents and ...
ELUCIDATING MECHANISMS FOR PERSISTENT INFECTION BY THE RELAPSING FEVER SPIROCHETE BORRELIA HERMSII
Relapsing fever is a tick-borne bacterial disease caused by a number of species in the genus Borrelia. Persistence is a key component of the lifecycle of relapsing fever Borrelia as it improves the chance for tick acquisition ...
STRUCTURAL CHARACTERIZATION OF THE ANAPLASMA MARGINALE ANTIGENICALLY VARIANT MSP2 PROTEIN
Antigenic variation allows pathogens to escape host immune responses and establish persistent infection. Anaplasma marginale uses gene conversion from a genomic allelic repertoire to generate msp2 expression site variants. ...
