Geographical distribution of Pseudomonas pseudomallei in China.

1,366 samples of soil and water from southern China coastal provinces were examined for Pseudomonas pseudomallei. Data showed that 58 samples were positive for this bacteria, which is primarily distributed in Hainan Province and the coastal region of mainland. This paper confirmed the environmental presence of P. pseudomallei in China and showed that the distribution of this pathogen has at least reached a latitude of 25.5 degrees north.
