Parapoxvirus infections in New Zealand farmed red deer (Cervus elaphus)     

Horner GW  Robinson AJ  Hunter R  Cox BT  Smith R 《New Zealand veterinary journal》1987,35(4):41-45

Outbreaks of infection due to a parapoxvirus were reported on eight New Zealand deer farms. Scabby lesions were seen variably on the muzzle, lips, face, ears and neck of red deer (Cervus elaphus) with morbidity rates reaching 100%. On three farms multifocal lesions were also present on the velvet. Deaths were reported on two properties where the lesions were extensive and secondary bacterial infections had occurred. On one of these farms multifactorial disease was suspected. Poxvirus particles were seen by negative contrast electron microscopy in scab material from all eight properties. Morphologically the deer virus resembled a parapoxvirus, but restriction endonuclease analysis showed its DNA fragment patterns were distinct from those of orf (contagious ecthyma) virus.  相似文献

Therapeutic trial of granulocyte-colony stimulating factor for dilated cardiomyopathy in three dogs     

Park C  Yoo JH  Jeon HW  Kang BT  Kim JH  Jung DI  Lim CY  Lee HJ  Hahm DH  Woo EJ  Park HM 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2007,69(9):951-955

Three dogs were presented to us for evaluation of cardiac problems. Electrocardiographic recordings revealed severe tachyarrhythmia and atrial fibrillation with ventricular tachycardia in 2 of the 3 dogs. The echocardiographic findings of the 3 dogs revealed markedly decreased fractional shortening and a marked increase in E-point septal separation. Based on the results of electrocardiographic and echocardiographic evaluation, the 3 dogs were diagnosed as dilated cardiomyopathy (DCM). The dogs were treated with conventional cardiac medication, but cardiac function did not improve and the clinical signs remained. We subsequently attempted treatment with granulocyte-colony stimulating factor (G-CSF; 10 microg/kg, subcutaneously). The specific purpose of G-CSF therapy for DCM was to improve cardiac function and a significant improvement in cardiac function was confirmed. The three dogs had no treatment side effects. This case report suggests that G-CSF might have therapeutic effects for medically refractory DCM in dogs.  相似文献   

从配合力分析探讨甘蔗家系抗黑穗病的育种潜力   总被引：2，自引：0，他引：2

采用5×4不完全双列杂交设计选配的第1次无性种茎为试验材料,在人工浸渍接种黑穗病菌条件下,估算了9个亲本及其组合在新植蔗和宿根蔗的配合力效应。结果表明:①20个家系抗性差异较大,以CP67/412、ROCl为母本的半同胞家系表现较强抗病性,而以CP72/1210、CP65/357为母本的半同胞家系表现一定感病性;②甘蔗抗黑穗病遗传是由加性效应基因和非加性效应基因共同控制;③发现CP67/412、ROClgca效应值较高,CP57/614次之,均具有可作为抗源亲本的育种潜力,④根据配合力总效应值评价组合,认为CP67/412×崖84/153、ROCl×崖71/374、CP67/412×崖71/374、ROCl×崖84/153、CP67/412×崖73/512、CP57/614×崖84/153是抗黑穗病较强的组合,可用于今后抗黑穗病育种计划。  相似文献   

CALCIUM: UNUSUAL SOURCES IN THE HIGHLAND PERUVIAN DIET     

BAKER BT  MAZESS RB 《Science (New York, N.Y.)》1963,142(3598):1466-1467

A dietary survey conducted in the southern highlands of Peru revealed two important sources of dietary calcium not previously reported. Mineral and ash calcium ingested as a food spice, and along with coca, raises the calcium intake from the low figures recorded by standard nutritional surveys to a more substantial level.  相似文献   

Evaluation of single-nucleotide polymorphisms in CAPN1 for association with meat tenderness in cattle   总被引：24，自引：0，他引：24  

Page BT  Casas E  Heaton MP  Cullen NG  Hyndman DL  Morris CA  Crawford AM  Wheeler TL  Koohmaraie M  Keele JW  Smith TP 《Journal of animal science》2002,80(12):3077-3085

Micromolar calcium activated neutral protease (CAPN1) was evaluated as a candidate gene for a quantitative trait locus (QTL) on BTA29 affecting meat tenderness by characterization of nucleotide sequence variation in the gene. Single-nucleotide polymorphisms (SNP) were identified by sequencing all 22 exons and 19 of the 21 introns in two sires (Piedmontese x Angus located at the U.S. Meat Animal Research Center in Clay Center, NE; Jersey x Limousin located at AgResearch in New Zealand) of independent resource populations previously shown to be segregating meat tenderness QTL on BTA29. The majority of the 38 SNP were found in introns or were synonymous substitutions in the coding regions, with two exceptions. Exons 14 and 9 contained SNP that were predicted to alter the protein sequence by the substitution of isoleucine for valine in Domain III of the protein, and alanine for glycine in Domain II of the protein. The resource populations were genotyped for these two SNP in addition to six intronic polymorphisms and two silent substitutions. Analysis of genotypes and shear force values in both populations revealed a difference between paternal CAPN1 alleles in which the allele encoding isoleucine at position 530 and glycine at position 316 associated with decreased meat tenderness (increased shear force values) relative to the allele encoding valine at position 530 and alanine at position 316 (P < 0.05). The association of maternal alleles with meat tenderness phenotypes is consistent with the hypothesis of CAPN1 as the gene underlying the QTL effect in two independent resource populations and presents the possibility of using these markers for selective breeding to reduce the numbers of animals with unfavorable meat tenderness traits.  相似文献
