Antibody titres to Streptococcus suis type 2 were measured with an enzyme linked immunosorbent assay (ELISA) in four occupational groups in New Zealand. No veterinary students, 9% of dairy farmers, 10% of meat inspectors and 21% of pig farmers were seropositive to S. suis type 2. The development of antibody to S. suis type 2 was associated with occupational contact with pigs or their meat products. Subclinical infection with S. suis type 2 appears to occur in humans and the antibody produced is of only short duration. The annual incidence of subclinical infection and seroconversion in pig farmers may approach 28%. Thus S. suis type 2 may be one of the most infectious potentially zoonotic agents present in New Zealand, although very rarely resulting in clinical disease.
在新西兰的四个职业群体中,采用酶联免疫吸附测定(ELISA)法检测了抗2型猪链球菌的抗体滴度。兽医专业学生中无人呈血清阳性,奶农中有9%、肉类检查员中有10%、养猪户中有21%对2型猪链球菌呈血清阳性。抗2型猪链球菌抗体的产生与职业性接触猪或其肉制品有关。2型猪链球菌的亚临床感染似乎在人类中发生,且产生的抗体持续时间较短。养猪户中亚临床感染和血清转化的年发病率可能接近28%。因此,2型猪链球菌可能是新西兰存在的最具传染性的潜在人畜共患病原体之一,尽管极少导致临床疾病。
