目的:棘球蚴病是反刍动物肺和肝囊肿的主要病因。这项研究比较了放射线照相和超声检查(USG)在检测患病牛动物的肺和/或肝囊肿中的有用性。该研究还研究了肺和肝囊肿的同时发生,以及这些囊肿是否是疾病的主要原因。
方法:本研究对患有肺和肝囊肿的45头患病牛(37头水牛和8头牛)进行。进行了完整的病史和临床检查。拍摄胸部和网状区域的侧向X光片。在放射学阳性或可疑的囊肿病例中,完成肺和肝区域的USG。根据囊肿的位置和动物的临床表现,囊肿被归类为疾病的主要或次要原因。
结果:使用任一成像技术,据观察,46.7%的动物有肺和肝囊肿,而33.3%只有肺,20%只有肝囊肿。囊肿仅在31.1%的动物中被确定为疾病的主要原因。为了诊断肺囊肿,X线摄影术(71.1%)和USG(62.2%)具有相似的诊断效用.然而,用于检测肝囊肿,USG是唯一的成像工具。
结论:肺和肝囊肿,根据它们的数量和大小可能是牛患病的主要原因。建议使用射线照相术和USG,结合起来,作为排除包虫病的筛查工具。
OBJECTIVE: Echinococcosis is the major cause of lung and liver cysts in ruminants. This study compared usefulness of radiography and ultrasonography (USG) in the detection of lung and/or liver cysts in sick bovine animals. The study also worked out cooccurrence of lung and liver cysts, and whether these cysts were primary cause of sickness or not.
METHODS: This study was conducted on 45 sick bovine (37 buffaloes and 8 cattle) suffering from lung and liver cysts. A complete history of illness and clinical examination was carried out. Lateral radiographs of chest and reticular region were taken. In radiographically positive or suspected cases of cysts, USG of the lung and liver region was done. Depending on the location of cyst and clinical manifestations of the animal, the cysts were categorized as primary or secondary causes of sickness.
RESULTS: Using either imaging technique, it was observed that 46.7% of the animals had both lung and liver cysts, whereas 33.3% had only lung and 20% had only liver cyst. Cysts were identified as primary cause of sickness in 31.1% animals only. For diagnosing lung cysts, radiography (71.1%) and USG (62.2%) had similar diagnostic utility. However, for detecting liver cysts, USG was the only imaging tool.
CONCLUSIONS: The lung and liver cysts, depending on their number and size may be a primary cause of sickness in bovine. Radiography and USG are recommended, in combination, as screening tools to rule out echinococcosis.
