| Popis: | We investigated the seasonal prevalence and diversity of clostridial spores in raw milk from the Tokachi area of Hokkaido. Samples of raw milk were collected quarterly from May 2013 through February 2014. The mean clostridial spore count for the raw milk from 336 milk tankers was 27.6 CFU/100 ml. The clostridial species isolated most frequently from raw milk samples was Clostridium tyrobutyricum. The dominant species was C. tyrobutyricum regardless of the season. The percentage of samples with low spore counts (10 CFU/100 ml) was highest (60.9%) during winter (February) and lowest (34.5%) in autumn (November). In comparison, the percentage of samples with high spore counts (100 CFU/100 ml) was highest (5.7%) in autumn (November) and lowest (1.1%) during spring (May). |
