H. Fukushima et al., ISOLATION OF YERSINIA-PSEUDOTUBERCULOSIS FROM RIVER WATERS IN JAPAN AND GERMANY USING DIRECT HOH AND HELA-CELL TREATMENTS, Zentralblatt fur Bakteriologie, 282(1), 1995, pp. 40-49
Yersinia pseudotuberculosis was recovered from precipitates directly t
reated with KOH and/or HeLa cell in 25.7% of 680 river water samples c
ollected in Japan. Recovery was nil in similar samples from Germany. T
reatment of precipitates by KOH and infection of HeLa cells, respectiv
ely, is an expedient and selective means for isolation of Y. pseudotub
erculosis from such samples.
