我国沿海副溶血性弧菌血清型分布的实验调查

对135株来自我国沿海海产鱼贝类、海水、海泥及食物中毒患者的副溶血性弧菌,进行了血清学分型实验。结果表明:属于已知OK抗原型的106株(78.5%),分布于O1~12群的29个血清型。另有10株菌(7.4%)的血清型属于8个已知K抗原与其它O群组合的新菌型(神奈川现象阴性)。从群别看,以O₄群最多(38/30.4),O₁群次之(26/20.8);从型别看,以O₁K₃₂最多(18/14.4),O₅K₁₇次之(10/8.0)。O₁~O₅群菌株为108株80%)。仅具有O群抗原而未检出K抗原的有19株(14.1%)。不同样品的菌型分布未发现有特殊差异。

A Study of Serological Typing Distribution on Vibrio parahaemolyticus along the Off-shore of China

Serologic typing of 135 strains of Vibrio parahaemolyticus isolated from the off-shore fish, shellfish, sea-water, seamud and food poisoning patients was studied. The results showed that 106 strains (78.5%) known as OK antigen type or, 29 serotypes aranging from O 1 to 12 groups. The other 10 strains (7.4%) were the new sero-types formed of known K antigen and O group (Kanagawa negative). As for the groups, most of strains were O₄ group (38/30.4) and the second was 01 group (26/20.8). The majority of the sero-types were O₁K₃₂ (18/14.4) and O₅K₁₇(10/8.0). The numbers of strain of O₁-O₅ groups was 108 (80%). 19 strains could be classified as O groups, but no K antigen was detected (14.1%). No special dissimilarity has been found in sero-types distributed over various samples.
