概括

在中国,调查了导致堕胎的主要原因 - - 绵羊中毒菌病. 虽然患病率似乎正在下降,但Toxoplasma gondii仍然对绵羊养殖构成威胁,不应被忽视.

科学领域:

兽医寄生虫学兽医寄生虫学
分子生物学分子生物学
流行病学流行病学

背景情况:

绵羊毒菌严重影响绵羊养殖,主要导致堕胎.
了解Toxoplasma gondii的流行和遗传特征对于羊的健康管理至关重要.

研究的目的:

为了调查在中国的绵羊毒素菌的流行情况.
评估Toxoplasma gondii在绵羊群中的潜在危害.
为了隔离和描述循环中的T. gondii菌株.

主要方法:

在1035只羊血清上使用修改的聚合试验 (MAT) 进行血清检测.
通过聚合酶链反应 (PCR) 在164只绵羊样本上进行分子检测.
从阳性样本中通过小鼠生物试验分离T. gondii菌株.

主要成果:

按MAT计算,T. gondii的血清流行率为7.2% (75/1035) (滴值≥1:100).通过MAT计算,T. gondii的血清流行率为7.2% (75/1035).
通过PCR,分子患病率为16.4% (27/164).
从绵羊组织中分离出一种可活的,有毒的I型菌株 (TgSheepCHn15),这是第一次报告的小鼠病例.

结论:

中国羊群中毒菌的患病率可能正在下降,但仍然是一个重大问题.
隔离了一种有毒的I型菌株凸显了T. gondii在绵羊中的复杂流行病学.
持续的监测和控制措施是必要的,以减轻绵羊毒素菌的影响.

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Bacterial Phylum Spirochaetes

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
