一例大食蚁兽感染艾美耳球虫的报道

在对北京动物园从南非引进的大食蚁兽进行检疫时发现粪便中有大量球虫卵囊,经鉴定为艾美耳球虫Eimeriaescomeli(Rastegaieff,1930)Levine and Becker,1933。从大食蚁兽新排出的粪便中收集卵囊并进行分离培养,卵囊经28℃孵化8 d可完全孢子化。卵囊多为椭圆形或亚球形,卵囊壁粗糙,呈棕黄色,无卵膜孔。卵囊的大小为长20.9±2.59μm,宽18.7±2.25μm,形状指数为1.1±0.07。卵囊壁厚度为1.1±0.18μm,分两层,外层厚,棕黄色的卵囊壁有放射状条纹,内层膜较薄,并且松散。卵囊内常有残体。孢子囊呈长卵圆形,轻微不对称,有斯氏体。大小为5.5～10.8μm×3.4～5.6μm,平均8.68μm×4.21μm。子孢子长形,平行排列,头尾相对。

仔猪缺铁的原因分析及防治措施

铁缺乏症又称仔猪营养性贫血或仔猪缺铁性贫血,是由于机体铁缺乏而引起猪贫血和生长受阻的营养代谢病。临床上以血红蛋白含量降低、红细胞数减少以及皮肤、黏膜苍白为主要特征。多发于2～4周龄的哺乳仔猪,集约化猪场比较容易发生本病,以冬春季节发病率较高。     

一例鸡传染性贫血与大肠杆菌病并发的诊治

鸡传染性贫血(chickeninfectiousanemia,CIA)是由圆环病毒属的鸡传染性贫血病毒(chickeninfectiousanemiavirus,CIAV)引起的一种以雏鸡骨髓脂肪变性引发的再生障碍性贫血和胸腺等淋巴组织萎缩为主要特征的传染病,是鸡主要的免疫抑制病之一。CIAV在鸡群中广泛存在,可经水平传播和垂直传播,且病毒通过种鸡卵巢或精液传给子代是造成雏鸡暴发该病的主要原因。种鸡开产前不久或产蛋初期感染CIA,会有3~6周左右的垂直传播,种鸡本身生产性能没有明显影响,但其子代缺乏母源抗体,易感染该病毒并继发细菌感染。本文介绍了一例鸡传染性贫血病毒和大肠杆菌混合感染的诊治。     

一例犬免疫介导性溶血性贫血的诊治

<正>犬免疫介导性溶血性贫血是由于红细胞表面覆盖有免疫球蛋白或补体导致红细胞存活时间缩短,红细胞大量短时间破坏而产生急性血管内溶血的一种免疫性疾病。这是犬最常见的溶血性疾病,多为再生性贫血。此病多发于2~8岁犬,雌犬比雄犬发病率高。

Cabot rings as a result of severe dyserythropoiesis in a dog

An 11-year-old female Dachshund was presented with depression, diarrhea, weight loss, and radiographic evidence of masses involving the liver, spleen, and cranial lobe of the right lung. Results of a CBC included severe nonregenerative anemia (HCT 14.2%, hemoglobin, 4.3 g/dL, reticulocytes 66,000/microL) with marked metarubricytosis (nucleated RBCs 6.39 x 10(3)/microL). Examination of the peripheral blood smear revealed marked erythroid dysplasia, including marked anisocytosis with a prevalence of macrocytes, Howell-Jolly bodies, diffuse basophilic stippling, and multinucleated and atypical nucleated RBCs. Neutrophil hypersegmentation and giant forms were also noted. Numerous erythrocytes, particularly polychromatophilic cells, contained inclusions consistent with Cabot rings, which appeared as delicate red-purple ellipsoid or figure 8 structures. Rarely, Cabot rings were observed extracellularly. The dog was treated symptomatically with blood transfusions, prednisone, erythropoietin, and vitamin supplementation, but the anemia progressively worsened. The dog was euthanized 2 months after presentation. Bone marrow aspirate and core biopsy specimens obtained at the time of euthanasia revealed marked dysplastic changes in all cell lines, especially dyserythropoiesis, along with infiltrating carcinoma cells. A necropsy was performed, and histologic examination revealed poorly differentiated adenocarcinoma of the lung with multiple metastases to the marrow, spleen, and liver. The final diagnosis was marked myelodysplasia secondary to metastatic adenocarcinoma. Cabot rings are found rarely in humans with myelodysplasia, but have not been described previously in dogs. Based on the findings in this case, Cabot rings may occur rarely in dogs with severe dyserythropoiesis.

A hematologic and blood chemical study of Swedish purchased calves.

The hemoglobin (Hb), packed cell volume (PCV), erythrocytes (R.G.), serum iron (SI) and unsaturated iron binding capacity (UIBG) were examined in a total of 386 purchased calves for the duration of 1 year. The calves were tested within 3 days of arrival at the buyer’s herd. The average age of the calves was 28 ± 10 days ().The results may be summarized as follows:

1. Approx. 35% of the calves had Hb values ≦ 10.0 g/100 ml.
2. Fifteen% of the calves had ≦ 6.0 × 10⁶ R.C. per µl.
3. Fifty-three calves or about 14% showed SI values ≦ 40 µg/100 ml and 131 calves or 34% ≦ 80 µg/100 ml.
4. Twenty-seven % of the calves had UIBG values > 501 µg/100 ml.
5. Almost half the calves (48%) had a saturation percentage of transferrin with iron below 20% and 138 calves (36%) below 15%.

These figures among others in the study indicate that 13–35% of the purchased calves suffered from iron deficiency anemia.     

藏系绵羊钼诱导铜缺乏的研究

自2000年以来,青海省乌兰地区藏绵羊出现以异食、消瘦和贫血为特征的疾病。经分析该地区土壤、牧草和动物的矿物质元素含量,发现在患病区,土壤钼含量为（4.63±1.51）μg/g,牧草为（4.89±1.79）μg/g,极显著高于正常地区。患病动物血液平均铜含量为（0.23±0.07）μg/g,被毛铜平均含量为（3.27±0.71）μg/g,而正常区的动物为（0.97±0.23）μg/g和（6.78±1.57）μg/g,差异极显著;患病动物血液铜最高值为0.53μg/g,血液铜最低值为0.031μg/g。而正常地区藏绵羊血液铜含量最高值为1.33μg/g,血液铜最低值为0.83μg/g。同时患病动物血清铜蓝蛋白显著低于正常动物,并且有小红细胞贫血。结果表明,藏绵羊以异食、消瘦和贫血为特征的营养代谢疾病为钼诱导的次级铜缺乏。     

桑叶黄化失绿症的研究

江苏沿海地区发现桑叶黄化失绿,是一种缺铁为主的缺乏微素综合症。起因于桑园土壤缺乏有效铁,以及土壤中pH值高,并呈HCO_3-离子反应,使铁的有效性降低,致使桑叶活性铁含量下降。另一方面是大量吸收磷素,使植株内磷铁比失调,影响铁的运转,大幅度降低过氧化氢酶和过氧化物酶的活性,影响正常的生理代谢。防治措施:及时喷铁叶面肥、树干注射铁液、增施有机肥料等。     

母猪补血的必要性

母猪贫血会造成产弱仔、新生仔猪活力不足等问题,也会使母猪产程延长、导致发情异常等系列生产问题,但该问题尚未引起行业内的重视.尽管铁是动物机体必不可少的微量元素之一,但补铁不一定能解决母猪贫血问题.文章概述了母猪贫血的原因、后果和解决措施,希望为行业提供解决母猪贫血问题的新思路.
