柑桔溃疡病是日本、台湾、印度和南美部分地区柑桔果树一种毁坏性的细菌疾病。四十年来虽然柑桔的溃疡病并未在美国出现过,但是柑桔种植者仍担心这种病害的突然爆发,在过去的五年中海关检查员已查出有2500起柑桔果实带有这种疾病。现在柑桔种植者确在请求SEA科学家研制一种检查柑桔果实这种早期疾病的快速、简易、准确的检验方法。为回答这一请求,病理学家锡弗拉罗(L. Civerolo)正在评定一个技术上非常不简单的血清试验,即带酶的免疫吸着剂试验,简称EUSA,用来检查引起柑桔溃疡病的细菌性病源(Xanthomonas citri)。这种试验曾经一度用于检查动物体上的病原体,但
Citrus canker is a devastating bacterial disease of citrus fruit trees in parts of Japan, Taiwan, India and parts of South America. Although citrus canker disease has not been reported in the United States for 40 years, citrus growers are still worried about the sudden onset of the disease. In the past five years, customs inspectors have detected 2,500 citrus fruits This disease. Now citrus growers are actually asking SEA scientists to develop a quick, easy and accurate test for detecting the early illness of citrus fruits. In response to this request, the pathologist Lucius Civerolo is assessing a technically very infrequent serum test, the Enzyme Immunosuppressant Trial, or EUSA for short, to check for citrus canker Xanthomonas citri. This test was once used to examine pathogens in animals but
