Surgical removal of a fish hook from the oesophagus of a turtle     

RJ HYLAND 《Australian veterinary journal》2002,80(1):54-56

An adult male Macquarie turtle was presented for examination after swallowing a fish hook. Radiographs taken to determine the position of this foreign body within the gastrointestinal tract revealed the fish hook lodged in the turtle's oesophagus. Surgical removal of the fish hook involved an approach through the soft tissues of the lateral neck. The turtle recovered well and was returned to the wild.  相似文献

Microbiological evaluation of dressing procedures for crocodile carcases in Queensland     

MW RICKARD  AD THOMAS†  S. BRADLEY‡  J. FORBES-FAULKNER†  RJ MAYER† 《Australian veterinary journal》1995,72(5):172-176

SUMMARY Microbiological testing of crocodiles during the dressing procedure has shown that sanitising the skin before skinning reduces the bacterial count on the skin and that dipping crocodile meat in 1.3% acetic acid solution effectively reduces bacterial levels. The total bacterial count on the processed meat sample was comparable with that obtained in the beef, pork and lamb industries. Salmonellae were isolated from 14 of the 72 carcases. Most (65%) of these isolates were in Salmonella subspecies III, formerly classified as Arizona.  相似文献   

Spatial Patterns in the Economic Development of the Mountain West     

DOUGLAS E. BOOTH 《Growth and change》1999,30(3):384-405

ABSTRACT Many counties in the mountainous areas of the western U.S. are experiencing rapid growth in population and income, even though extractive industries that served historically as their primary economic base are in decline. The purpose of this paper is to establish statistically the spatial determinants of population, employment, and income densities in 86 rural mountain counties and any changes in those determinants between 1985 and 1994. The results of this analysis indicate that densities are oriented to regional metropolitan centers and critical amenities such as ski areas, national parks, and universities or colleges. Negatively sloped density gradients with respect to distance from regional metropolitan centers suggest that the densities of settlement patterns beyond metropolitan boundaries are analogous to those within metropolitan areas relative to urban centers. In short, a tension apparently exists in locational choice; residents of the Mountain West desire to live near the beauties and amenities of the mountain landscape but do not want to entirely sever their urban ties. Because amenities are the primary attraction of mountain counties rather than employment in locationally dependent industries, at least some migrants must have relatively footloose forms of income.  相似文献   

Programs for surveillance and monitoring of antibacterial residues in Australia, 1989 to 1993   总被引：1，自引：0，他引：1  

TJ NICHOLLS  NL BLACKMAN  IB STEPHENS  RJ WILD† 《Australian veterinary journal》1994,71(12):397-399

SUMMARY The development of a State-based confirmatory testing capability for antibiotic residues in meat in Australia has allowed the rapid feedback to producers failing to comply with antibiotic maximum residue limits. The identification of problem areas in various categories of livestock, and subsequent focused surveillance programs, has reduced the prevalence of antibacterial residues in both domestic and export meat products. Failure to observe withholding periods of antibacterial drugs after treatment is the most significant cause of non-compliance. In the period July 1991 to June 1993 the compliance rate for antibacterial residues for all species was 99.9%.  相似文献   

A screening test for subclinical liver disease in horses affected by pyrrolizidine alkaloid toxicosis     

JM CURRAN  RJ SUTHERLAND  RL PEET 《Australian veterinary journal》1996,74(3):236-240

Objective: To evaluate various biochemical tests as indicators of subclinical liver disease in horses exposed to pyrrolizidine alkaloid toxicosis.
Design: A clinical pathology field study.
Animals: Twenty-two clinically normal horses from four properties in the Kimberley region of Western Australia.
Procedure: Serum samples from each horse were assayed for gamma glutamyltransferase, alkaline phosphatase and aspartate aminotransferase activities, and for serum bile acid concentration, albumin and total protein. Serum protein electrophoresis was performed and their amino acid profiles determined. Bromosulphophihalein halfclearance times were measured. Horses were then subjected to a single liver biopsy. Results were analysed by, variance of group means, the Fisher-Irwin exact test, and by sensitivity and specificity calculation.
Results: Horses were classified into 2 groups, of 10 unaffected and 12 subclinically affected, on the basis of liver histology. Significant differences between the unaffected and subclinical groups were observed for gamma glutamyltransferase and alkaline phosphatase activities (P < 0.01). Gamma glutamyltransferase had sufficient sensitivity (75%) and specificity (90%) to function as a primary screening test for subclinical liver disease in horses exposed to pyrrolizidine alkaloids. Alkaline phosphatase was useful, but with lower sensitivity (58%).
Conclusion: Serum gamma glutamyltransferase activity is a useful screening test for detecting subclinical liver disease in horses exposed to pyrrolizidine alkaloids under field conditions in northern Australia.  相似文献   

Impact of dung from ivermectin-treated sheep on oogenesis and survival of adult Lucilia cuprina     

RJ MAHON  KG WARDHAUGH 《Australian veterinary journal》1991,68(5):173-177

Females of the Australian sheep blowfly, Lucilia cuprina, exploit sheep dung as a source of protein for egg development. Flies fed on dung collected from sheep 1 to 6 days after being drenched with the broad-spectrum antiparasitic drug ivermectin showed delayed reproductive development and reduced fecundity. Male and female survival was also reduced. Despite these effects, except where the recommended frequency of drenching (1 to 4 times per annum) is greatly exceeded, it is unlikely that ivermectin residues will affect any useful reduction in blowfly populations.  相似文献
