猪传染性胸膜肺炎放线杆菌鉴定与耐药性试验

猪传染性胸膜肺炎(PCP)的病原是传染性胸膜肺炎放线杆菌(APP),传染性胸膜肺炎是一种威胁全国养猪业的呼吸道细菌性疾病,除了引起感染猪只死亡外,还可变为慢性疾病,使生产能力下降,导致医药和疫苗的费用不断增加,造成养殖户严重的经济损失.本试验对兰考县某猪场发生的猪传染性胸膜肺炎放线杆菌感染进行初步研究,分离鉴定猪传染性胸膜肺炎放线杆菌5株,获得其对抗生素的敏感性结果,为该病的防治提供科学依据.     

猪胸膜肺炎放线杆菌的分离鉴定及致病性研究

正猪传染性胸膜肺炎(porcine infectious pleuropneumonia,PCP)是由猪胸膜肺炎放线杆菌(Actinobacillus pleuropneumoniae,APP)引起的一种高度传染性呼吸道疾病,该病主要以肺脏出血、坏死和纤维素性渗出为主要病变特征,可致各年龄段猪只发生感染[1]。急性感染死亡率高,慢性感染可使病原菌长期潜伏于猪群内,致使猪只生长缓慢,饲养报酬降低,     

谨防猪高热综合征继发性感染

副猪嗜血杆菌病 (一)该病当前流行特点在猪群发生高热综合征时,猪只感染蓝耳病病毒、圆环病毒2型,伪狂犬病病毒,猪流感病毒和猪瘟病毒后,常见继发感染副猪嗜血杆菌,并与巴氏杆菌、链球菌,传染性胸膜肺炎放线杆菌与支原体等混合感染,使疾病多样化,病情复杂化,大大地增高了发病率和死亡率,造成很大的经济损失.     

血清3型猪传染性胸膜肺炎放线杆菌的分离与鉴定

2005年3月,广东省惠州市某猪场发生了一起疑似猪传染性胸膜肺炎放线杆菌引起猪只死亡的病例,经细菌分离培养、生化鉴定、PCR、血清学鉴定,确诊该病原为血清3型猪传染性胸膜肺炎放线杆菌。     

一例猪传染性胸膜肺炎的治疗

传染性胸膜肺炎是由胸膜肺炎放线杆菌引起猪的高度传染性呼吸道疾病,又称猪接触性传染性胸膜肺炎。以急性纤维素性胸膜肺炎和慢性局灶性坏死性胸膜肺炎为特征,急性型呈现高死亡率,本病的病原为胸膜肺炎放线杆菌。随着气候逐渐变冷,加之气候干燥、猪舍通风不良,我市郊区部分养殖户发生猪传染性胸膜肺炎。     

猪传染性胸膜肺炎放线杆菌血清2型PCR程序优化及分子鉴定

猪接触性传染性胸膜肺炎（porcine contagious pleuropneumonia,PCP）又称坏死性胸膜肺炎,是由胸膜肺炎放线杆菌引起的一种高度接触传染性、致死性呼吸道传染病。以急性出血性纤维素性肺炎和慢性纤维素性坏死性胸膜炎为主要特征。各种年龄、性别的猪对本病均易感,急性者死亡率高,慢性者常能耐过。猪传染性胸膜肺炎放线杆菌有15个血清型,不同血清型之间没有或仅有较弱的交叉保护作用,这给猪传染性胸膜肺炎放线杆菌的诊断防治和免疫预防带来了很大的困难。因此建立一种快速血清型分子鉴定方法尤为重要。为了快速、简便的建立猪传染性胸膜肺炎放线杆菌血清型分子鉴定的方法,本研究所从临床发病疑似病例猪肺脏和气管中分离到的放线杆菌,首先经过血清型鉴定,确定部分血清型为2型,为了确定血清型鉴定的准确性,在此基础上,采用分子鉴定的方法,对这些菌株进行鉴定,确定分离到的11株菌为猪胸膜肺炎放线杆菌血清2型。这为猪传染性胸膜肺炎放线杆菌血清型分子鉴定及防治提供了理论依据,为今后临床血清型定型提供了一种简便方法。

春季猪传染性胸膜肺炎的预防

猪传染性胸膜肺炎是由胸膜肺炎放线杆菌引起猪的高度传染性呼吸道疾病,又称为猪接触性传染性胸膜肺炎,以急性出血性纤维素性胸膜肺炎和慢性纤维素性坏死性胸膜肺炎为特征,急性型呈现高死亡率。     

猪传染性胸膜肺炎的诊断及防控

胸膜肺炎放线杆菌(APP)是猪传染性胸膜肺炎的病原。猪传染性胸膜肺炎是猪感染胸膜肺炎放线杆菌后发生的一种高度接触性的呼吸道传染性疾病。感染了胸膜肺炎放线杆菌的患病猪在临床中主要出现急性或慢性出血性纤维素性的胸膜肺炎和纤维素性的坏死性的胸膜肺炎为主要的特征性临床症状。该病的急性病例往往以死亡而告终,而慢性病例一般可以耐过痊愈,但是其仍然具有传染性。本文对猪传染性胸膜肺炎的病原、流行病学、临床症状、病理变化、防控措施进行了阐述,期望对相关工作者带来帮助,降低此病的发生,促进养猪业发展。

Disease and destiny-mystery and mastery

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures.     

Foot and mouth disease and bluetongue: differences and similarities

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures.
