Avian Vacuolar Myelinopathy Outbreaks At A Southeastern Reservoir, J Fischer, L Lewis-Weis, C Tate, J Gaydos, Richard Gerhold Jr., R Poppenga

Richard W. Gerhold Jr., DVM, MS, PhD

Avian vacuolar myelinopathy (AVM) is a neurologic disease of unknown etiology that affects bald eagles (Haliaeetus leucocephalus), American coots (Fulica americana), and several species of waterfowl. An unidentified neurotoxin is suspected as the cause of AVM, which has been documented at several reservoirs in the southeastern United States. We conducted diagnostic and epidemiologic studies annually during October-March from 1998-2004 at Clarks Hill/Strom Thurmond Lake on the Georgia/South Carolina border to better understand the disease. Avian vacuolar myelinopathy was confirmed or suspected as the cause of morbidity and mortality of 28 bald eagles, 16 Canada geese (Branta canadensis), six ...


Male Influx, Infanticide, And Female Transfer In Macaca Radiata Radiata, Mewa Singh, H Kumara, M. Kumar, Mirdula Singh, Matthew Cooper Mar 2006

Male Influx, Infanticide, And Female Transfer In Macaca Radiata Radiata, Mewa Singh, H Kumara, M. Kumar, Mirdula Singh, Matthew Cooper

In bonnet macaques, males usually disperse between groups and females remain philopatric, but researchers have reported female transfer. We report a rare case of male influx during the mating season in our bonnet macaque study group in the Anaimalai Hills. The density of bonnet macaques in the study region was unusually high. The study group had a single, crippled adult male with a long tenure and 5 adult females. During the mating season, adult females approached and mated with outgroup males, and then several males entered the group. The adult male left the group without any resistance. The incoming males ...

The Relationship Of Soil Province To Molecular Characterization And Phylogenetic Analysis Of Cryptosporidium Parvum Isolated From Calves In Georgia., Debra Miller, M. Mauel, A. Liggett, M. Hines Ii, K. Fraizer, M. Pence, L. Whittington, C. Baldwin

Although Cryptosporidium spp. are found throughout the world and in multiple environmental conditions, few data are available that explore the possibility of an association between specific environmental parameters and the species or strain of Cryptosporidium. This study examines the potential association between a particular Cryptosporidium species/strain found in calves and soil provinces in Georgia, USA. Necropsy cases spanning the years 1996-2002 were tested. No significant differences (P=0.962, chi(2) test of homogeneity) between numbers of positive cases were noted among soil provinces. Phylogenetic analysis of the sequences for the PCR products revealed sequence similarity of the products ...

Subcutaneous Haemangiosarcoma In A Cockatiel (Nymphicus Hollandicus)., D. Sledge, Z. Radi, Debra Miller, B. Lynn

Debra L Miller

An ulcerated, 1 x 0.5 cm, subcutaneous mass on the craniolateral aspect of the right tibiotarsus of a 4-year-old male cockatiel was removed. Histologically, the neoplasm was non-encapsulated, infiltrative and composed of irregular vascular channels lined by branching and variably sized spindle-shaped cells with large vesicular nuclei, prominent nucleoli and rare mitoses. Surrounding these vascular channels were fibroblasts and mixed inflammatory cells. Neoplastic cells had diffuse immunoreactivity to factor VIII supporting a diagnosis of haemangiosarcoma.

This study documents the seroprevalence of feline immunodeficiency virus (FIV) and puma lentivirus (PLV) in free-ranging and captive Florida panthers (Puma concolor coryi) (n = 51) and translocated Texas cougars (P. concolor stanleyana) (n = 10) from 1985 to 1998. The sera were tested for anti-FIV antibodies by enzyme-linked immunosorbent assay (ELISA) and Western blot tests. The ELISAs were read kinetically (KELA) and the sera were retrospectively examined by PLV peptide ELISA. Eleven panthers and one cougar were positive by KELA; 4 panthers and 4 cougars were equivocal; 35 panthers and 5 cougars were negative; and 1 panther had no data. Seven ...
