A total of 369 samples of nono, furanono and manshanu were purchased from four different markets around Zaria, Nigeria. Five hundred and sixty-eight staphylococcal isolates were obtained from the three products of which a total of 37 (6.5%) were enterotoxigenic comprising 21 (10.7%) from nono samples and 16 (17.2%) from fura samples. The staphylococcal count, pH and titratable acidity of all the samples that contained enterotoxigenic staphylococci ranged from 5.4 × 10 to 6.3 × 10 CFU/ml, 3.89 to 4.21 and 0.47 to 0.74, respectively. Of all the staphylococcal isolates, 6.5% produced enterotoxin. Of the enterotoxigenic strains encountered 73.0% produced enterotoxin A, 10.8% B, 10.8% C and 2.7% produced combinations of A and B and A and C each. Statistical analysis revealed no correlation between either coagulase, thermonuclease, hemolysin production and enterotoxin production.
从尼日利亚扎里亚周围的四个不同市场购买了总共369份nono、呋喃nono和manshanu样本。从这三种产品中获得了568株葡萄球菌分离株，其中共有37株（6.5%）产肠毒素，包括来自nono样本的21株（10.7%）和来自fura样本的16株（17.2%）。所有含有产肠毒素葡萄球菌的样本的葡萄球菌计数、pH值和可滴定酸度分别为5.4×10至6.3×10 CFU/ml、3.89至4.21和0.47至0.74。在所有葡萄球菌分离株中，6.5%产生肠毒素。在遇到的产肠毒素菌株中，73.0%产生肠毒素A，10.8%产生B，10.8%产生C，2.7%分别产生A和B以及A和C的组合。统计分析表明，凝固酶、热核酸酶、溶血素产生与肠毒素产生之间均无相关性。
