Investigation of long-term field experiments on response of breeding lines to common scab in a potato breeding program     

G. C. C. Tai  A. M. Murphy  Xingyao Xiong 《Euphytica》2009,167(1):69-76

Common scab, caused by Streptomyces scabies, is a disease that produces scab-like surface lesions on potato tubers. Testing for susceptibility/resistance of breeding lines at the Potato Research Centre of Agriculture & Agri-Food Canada (AFC) is carried out in a scab nursery maintained at AFC for the annual scab evaluation field trials. A replicated field trial routinely consists of breeding lines from previous testing season(s) plus newly selected lines. Data of scab scores generated from long-term experiments thus formulate an incomplete 2-way table over combinations of breeding lines (genotypes) and trials (years). This requires an advanced statistical method to estimate genetic parameters for evaluation purposes. A data base with 1,435 scab index scores from 344 breeding lines were extracted from 5 years (1995–1999) of field experiments in the scab nursery maintained at AFC. The statistical method Residual Maximum Likelihood (REML) was employed to estimate variance components of the breeding population and Best Linear Unbiased Predictor (BLUP) was used to predict genetic merit of breeding lines. High heritability was obtained from variance components estimated by REML. The BLUP scores of breeding lines provided reliable evaluation of their responses to common scab. Two data base sub-sets were separately formulated from the original data base for those parents and grandparents of the breeding lines having pedigree records available. They were again subjected to REML and BLUP analyses to compare the responses to common scab and identify sources of resistance at the parental and grandparental levels. Two random data sets with equal sized samples of breeding lines were also generated from the over-all data base. The two sets of BLUP scores between corresponding breeding lines and parents showed high association which provides an assessment of the validity of the evaluation process.  相似文献   

The prevalence and distribution of Mycobacterium bovis infection in European badgers (Meles meles) as determined by enhanced post mortem examination and bacteriological culture     

D. Murphy  E. Gormley  D. O’Meara 《Research in veterinary science》2010,88(1):1-5

The accurate diagnosis of Mycobacterium bovis infection in badgers is key to understanding the epidemiology of tuberculosis in this species and has significant implications for devising strategies to limit spread of the disease. In this study, badgers (n = 215) in the Republic of Ireland were examined at post mortem and tissues were collected from a range of anatomical locations and pooled into groups for bacterial culture of M. bovis. By assessing confirmed gross visible lesions (VL) alone, infection was detected in 12.1% of badgers. However, by including the results of all culture positive pooled samples, the overall infection prevalence increased significantly to 36.3%. Two-thirds (66.7%) of infected animals had no visible lesions (NVL). While the thoracic cavity (lungs and pulmonary lymph nodes) was found to be the most common site of infection, in a proportion of animals infection was absent from the lungs and draining lymph nodes and was confined to the lymph nodes of the carcase or the head. This may indicate an early extrapulmonary dissemination of infection or alternatively, in the case of the head lymph nodes, a secondary pathogenic pathway involving the lymphoid tissues of the upper respiratory tract (URT).  相似文献   

Eyelid malformation in four cockatiels     

N C Buyukmihci  C J Murphy  J Paul-Murphy  D V Hacker  L J Laratta  D E Brooks 《Journal of the American Veterinary Medical Association》1990,196(9):1490-1492

Four unrelated cockatiels had various degrees of maldevelopment of the eyelids. Only 1 eye of the 8 was normal. The condition had features compatible with ankyloblepharon or cryptophthalmos. Attempts were made to surgically establish an artificial palpebral fissure. Despite extensive surgical intervention and postoperative topical administration of corticosteroids, the skin over the orbit reverted to the preoperative state in all birds. Anecdotal information along with our findings suggest that this condition, although uncommon, is widespread in the cockatiel population in the United States.  相似文献

Technical note: mineral deposits on Dacron bags during ruminal incubation.     

J van Milgen  M L Roach  L L Berger  M R Murphy  D M Moore 《Journal of animal science》1992,70(8):2551-2555

Extensive DM contamination was found on Dacron bags that were incubated for prolonged periods of time in the rumen of steers fed alfalfa hay. The ash content of the contaminant was high, and most of it was acid-soluble X-ray analysis indicated the presence of hydroxylapatite and synthetic calcium magnesium phosphate or whitlockite. The contaminant appeared as a smooth coating on the Dacron fiber, suggesting that contamination was a gradual process rather than the result of entrapment of dislodged crystals from plant material. Contamination seemed to occur exponentially within the range of observations (0 to 42 d). Contamination also occurred in steers fed orchardgrass, although to a lesser extent than in steers fed alfalfa hay. The DM contamination was less than .04 g per bag (average bag weight was 1.2 g) during the first 10 d of incubation. However, correction for contamination might be required for studies involving longterm incubation or mineral digestion.  相似文献

Activity of beta-lactamase inhibitor sulbactam plus ampicillin against animal isolates of Pasteurella, Haemophilus, and Staphylococcus   总被引：2，自引：0，他引：2

Antibiotic susceptibilities of Pasteurella sp, Haemophilus pleuropneumoniae, and Staphylococcus aureus isolates were determined. The combination of sodium sulbactam, a beta-lactamase inhibitor, and ampicillin had a synergistic effect against all ampicillin-resistant pathogens, rendering them susceptible to ampicillin. Studies of cell-free beta-lactamase from Pasteurella and Haemophilus isolates confirmed the presence of a constitutive penicillinase. Inhibitory concentrations of sulbactam-ampicillin were bactericidal, as demonstrated by killing curves. Ampicillin-resistant Pasteurella and Haemophilus isolates did not develop resistance to sulbactam-ampicillin when passed as many as 8 times in the presence of sublethal concentrations of sulbactam-ampicillin. The in vitro synergistic activity of sulbactam-penicillin also was seen in an in vivo synergistic response in mice challenge exposed to an ampicillin-resistant P haemolytica.  相似文献
