Abstract Objective —To evaluate the relationship between width and depth of surgical margins, amount edema within around tumor, degree demarcation tumor surrounding tissues with clinical outcome following removal cutaneous mast cell tumors (cMCTs) in dogs. Design —Retrospective cohort study. Animals —100 dogs 115 resectable cMCTs. Procedures —Information about dogs' outcomes cMCT was obtained from primary care veterinarians. Histologic sections excised were assessed retrospectively for grade...
To evaluate clinical characteristics, outcome, and prognostic variables in a cohort of dogs surviving > 1 year after an initial diagnosis osteosarcoma.Retrospective case series.90 client-owned dogs.Medical records for 11-year period from 1997 through 2008 were reviewed, patients with appendicular osteosarcoma that lived histopathologic studied. Variables including signalment, weight, serum alkaline phosphatase activity, tumor location, surgery, adjuvant therapies recorded. Median survival...
In Ireland, every animal is examined at slaughter for its fitness human consumption. The aim of this study was to determine the relative effectiveness factories in submitting and subsequently having suspect lesions confirmed as bovine tuberculosis (TB) during years 2005-2007. This work provides an update from previously published data 2003-2004. During 2005-2007 were available on 4,401,813 cattle attested herds (i.e. classified free TB), which potential confounding factors 3,344,057...
Chemical capture is an essential tool in the management and conservation of white rhinoceros (Ceratotherium simum); however, cardiovascular responses immobilized megaherbivores are poorly understood. Blood pressure heart rate with etorphine or plus azaperone, effects subsequent i.v. butorphanol administration were investigated. Six used a randomized crossover study design four interventions: 1) i.m.; 2) azaperone 3) i.m. i.v.; 4) i.m., Etorphine resulted hypertension tachycardia on initial...
The 2 sites of bone marrow harvest for isolation mesenchymal stromal cells (MSC) in the horse are sternum and ilium. technical procedure is based on practitioner preference, but no studies have compared MSC concentrations growth rates between horses aged 2-5 years.The objective this study was to compare nucleated cell counts ilium consecutive 5 ml aspirates. We hypothesised that there would be a higher concentration MSCs than ilium, first sequential aspirate from either site yield greatest...
Ten white rhinoceros (Ceratotherium simum) were immobilized for a total of 13 procedures in holding facilities Kruger National Park using etorphine, azaperone, and hyaluronidase to assess the effect extended immobilization on serial cardiorespiratory, blood gas, lactate values. Butorphanol was administered intravenously following initial collection physiologic assessment (t=0). Respiratory cardiovascular parameters, body temperature, arterial gases monitored at 10-min intervals 100 min....
Bovine tuberculosis (TB) caused by Mycobacterium bovis is primarily a disease of ruminants, particularly cattle (Bos primigenius) and buffalo (Syncerus caffer), endemic in most developing countries. To date, studies done Uganda have documented the prevalence M. cattle, humans wild life, addition to non-tuberculous mycobacteria pigs. Pigs are increasingly becoming an important component livestock sector share human ecosystem rural Uganda. It therefore public health interest that they not...
Forty free-ranging white rhinoceros (Ceratotherium simum) were anesthetized with etorphine, azaperone, and hyaluronidase in Kruger National Park, South Africa, between February August 2009. Eighteen received butorphanol the dart combination, 22 had administered intravenously within 15 min of darting. Body position, blood gas values, heart rate, respiratory temperature measured at two time points after darting, approximately 10 apart (sample 1 mean collection 9.4 ± 2.7 min; sample 2 time,...
Diagnosis of tuberculosis in wildlife often relies on postmortem samples because logistical challenges and lack field-friendly techniques for live animal testing. Confirmation infection through detection infectious organisms is essential studying the pathogenesis epidemiology disease. We describe application a technique to obtain respiratory from free-ranging living lions facilitate viable Mycobacterium bovis under field conditions. identified M. by mycobacterial culture PCR tracheobronchial...
The role of Corynebacterium spp. in the pathogenesis canine and feline otitis externa/media their appropriate antimicrobial therapy are unclear. objectives this study were to (1) better establish pathogenicity utilizing reported criteria by assessing clinical response antibiotic (2) determine susceptibility patterns associated with otitis. was retrospective, targeting cultures positive for part mixed microbial populations 79/81 cultures. highly questionable because almost invariable presence...
Several strategies for eradicating Pseudorabies virus (Aujeszky's disease) in Chiang-Mai and Lampoon Provinces, Thailand, were compared using a computer simulation model, the North American Animal Disease Spread Model (NAADSM). The duration of outbreak, number affected herds destroyed during these simulated outbreaks. Depopulation, zoning restricted movement improved detection vaccination assessed. most effective to eradicate as per findings from this study are applying depopulation with...
