Bottlenose Dolphins as Marine Ecosystem Sentinels: Developing a Health Monitoring System
Randall S. Wells,Howard L. Rhinehart,Larry J. Hansen,Jay C. Sweeney,Forrest I. Townsend,Rae Stone,David R. Casper,Michael D. Scott,Aleta A. Hohn,Teri Rowles +9 more
TL;DR: A team of marine mammal veterinarians and biologists worked together to develop an objective, quantitative, replicable means of scoring the health of dolphins, based on comparison of 19 clinically diagnostic blood parameters to normal baseline values, which appears to roughly reflect dolphin health.
Journal ArticleDOI
Characterization and clinical manifestations of arcanobacterium phocae infections in marine mammals stranded along the central california coast
Shawn P. Johnson,Spencer S. Jang,Frances M. D. Gulland,Melissa A. Miller,David R. Casper,Judy Lawrence,Juliet Herrera +6 more
TL;DR: Sequence analysis of a portion of the 16S ribosomal RNA gene confirmed recent isolates as A. phocae, the first report of A.phocae in animals from the Pacific Ocean.
Journal ArticleDOI
Coccidioidomycosis and other systemic mycoses of marine mammals stranding along the central california, usa coast: 1998–2012
Sara E. Huckabone,Frances M. D. Gulland,Suzanne M. Johnson,Kathleen M. Colegrove,Erin Dodd,Demosthenes Pappagianis,Robin C. Dunkin,David R. Casper,Erin L. Carlson,Jane E. Sykes,Weiland Meyer,Melissa A. Miller,Melissa A. Miller +12 more
TL;DR: The first confirmation of C. gattii infection in a wild marine mammal from California and the first report of coccidioidomycosis in aWild harbor seal are reported, indicating temporal–spatial overlap may be observed for pathogenic mycoses infecting coastal marine mammals and adjacent human populations.
Journal ArticleDOI
Recovery rates of bottlenose dolphin ( Tursiops truncatus )carcasses estimated from stranding and survival rate data
James V. Carretta,Kerri Danil,Susan J. Chivers,David W. Weller,David S. Janiger,Michelle Berman-Kowalewski,Keith M. Hernandez,James T. Harvey,Robin C. Dunkin,David R. Casper,Shelbi Stoudt,Maureen E. Flannery,Kristin Wilkinson,Jessie Huggins,Dyanna M. Lambourn +14 more
TL;DR: The fraction of carcasses recovered for a population of coastal bottlenose dolphins (Tursiops truncatus) in California is estimated, using abundance and survival rate data to estimate annual deaths in the population and it is likely that carcass recovery rates of this population greatly exceed recovery rate of more pelagic dolphin species in the region.
Canine distemper vaccination is a safe and useful preventive procedure for southern sea otters
David A. Jessup,Michael J. Murray,David R. Casper,Deborah Brownstein,Christine Kreuder-Johnson +4 more
TL;DR: In this article, a commercial recombinant poxvirus vectored canine distemper (CD) vaccine was used to protect free-ranging sea otters from morbilivirus infection.
