The deaths of two Asian elephants (Elephas maximus) in August 1996 led the United States Department of Agriculture to require the testing and treatment of elephants for tuberculosis. From August 1996 to September 1999. Mycobacterium tuberculosis infection was confirmed by culture in 12 of 118 elephants in six herds. Eight diagnoses were made antemortem on(More)
Mycobacterium tuberculosis has become an important agent of disease in the captive elephant population of the United States, although current detection methods appear to be inadequate for effective disease management. This investigation sought to validate a multiple-antigen enzyme-linked immunosorbent assay (ELISA) for screening of M. tuberculosis infection(More)
The aim of this study was to design and evaluate a modified Ussing chamber, that makes use of constant air suction (modified Ussing air suction chamber, MUAS) for fixation of biopsy specimens. Standard size forceps biopsies were taken from the descending part of duodenum from patients undergoing endoscopy. Short circuit current (SCC) and conductance (G)(More)
OBJECTIVE To determine the minimum anesthetic concentration (MAC) of isoflurane in thick-billed parrots (Rhynchopsitta pachyrhyncha). ANIMALS 15 healthy thick-billed parrots. PROCEDURES Anesthesia was induced and maintained with isoflurane in oxygen. In the first bird that was anesthetized, end-tidal isoflurane concentration was maintained at 1.0% for(More)
Analyzing data obtained from web server logs, so-called “clickstreams”, is rapidly becoming one of the most important activities for companies in any sector as most businesses become ebusinesses. Clickstream analysis can reveal usage patterns on the company’s web site and give a highly improved understanding of customer behavior. This understanding can then(More)
OBJECTIVE To characterize clinical features of avian vacuolar myelinopathy (AVM) in American coots. DESIGN Case-control study. ANIMALS 26 AVM-affected American coots and 12 unaffected coots. PROCEDURES Complete physical, neurologic, hematologic, and plasma biochemical evaluations were performed. Affected coots received supportive care. All coots died(More)
Surgical procedures of the wing are commonly performed in companion, captive, and wild avian species. To develop a clinically applicable brachial plexus nerve block technique for perioperative analgesia in birds, 8 adult female mallard ducks (Anas platyrhynchos) were anesthetized and used in several local anesthetic trials with bupivacaine (2 or 8 mg/kg) or(More)
The effect of consumption of Immulina, a high-molecular-weight polysaccharide extract from the cyanobacterium Arthrospira platensis, on adaptive immune responses was investigated by evaluation of changes in leukocyte responsiveness to two foreign recall antigens, Candida albicans (CA) and tetanus toxoid (TT), in vitro. Consumption of Immulina by 11 healthy(More)
OBJECTIVE To determine the minimum anesthetic concentration (MAC) of sevoflurane in thick-billed parrots (Rhynchopsitta pachyrhyncha) and compare MAC obtained via mechanical and electrical stimulation. ANIMALS 15 healthy thick-billed parrots. PROCEDURES Anesthesia was induced in each parrot by administration of sevoflurane in oxygen. An end-tidal(More)
The efficacy, safety, and reliability of two ketamine-medetomidine-butorphanol anesthetic combinations were evaluated in 34 adult binturongs (Arctictis binturong). The animals were randomly assigned to one of the two groups. On the basis of estimated body weights, group high ketamine (HK) received ketamine (8 mg/kg, i.m.), medetomidine (0.02 mg/kg, i.m.),(More)
