Four blood isolates, 12 pneumonia isolates, and seven colonizing isolates of Branhamella catarrhalis were compared with respect to their ability to grow in normal human serum and in convalescent serum of a patient with B. catarrhalis bacteremia. Disease-causing isolates showed seven of 16 serum-resistant strains (43 percent) compared with one of seven (13 percent) colonizing strains. Bacteremic strains were not more serum-resistant than pneumonia-causing strains. Trypsin zones of inhibition were higher for disease-causing strains. There was no correlation between source of isolation and colistin sensitivity or ability to hemagglutinate red blood cells.
对4株血液分离株、12株肺炎分离株和7株卡他布兰汉菌定植分离株在正常人血清以及一位卡他布兰汉菌菌血症患者恢复期血清中的生长能力进行了比较。致病分离株中16株血清耐药菌株有7株（43%），而定植菌株7株中有1株（13%）。菌血症菌株的血清耐药性并不比致肺炎菌株更强。致病菌株的胰蛋白酶抑制圈更大。分离来源与黏菌素敏感性或红细胞血凝能力之间无相关性。
