Semisolid media for isolation of Salmonella spp. from coastal waters.
نویسندگان
چکیده
The use of two semisolid media (semisolid Rappaport and semisolid Rappaport-Vassiliadis) for the isolation of Salmonella spp. from coastal waters was compared with the use of conventional media. Two hundred and fifty six samples were studied; Salmonella spp. were detected in 83. The semisolid media were the most sensitive, detecting 73 samples instead of the 53 detected by the conventional media (P less than 0.001). The rate of isolation of Salmonella spp. showed an increase of 56.6% when the semisolid media were added to the conventional media, it being possible to detect 54.2% of the total organisms 1 day earlier.
