Introduction of Japanese Encephalitis Virus Genotype I, India

the epidemic PCR-ribotype 001. In particular, the identity between the 2 PCR ribotypes was 100% for the HMW proteins and 77% for the LMW proteins. This study provides convincing evidence that the S-layer is well conserved in C. diffi cile PCR-ribotype 027 strains and has high identity with the slpA of the epidemic PCR-ribotype 001. Because C. diffi cile PCRribotypes 027 and 001 are the most frequently isolated strains from severe CDIs across both North America and Europe (9,10), the result obtained suggests that the S-layer of these virulent strains presents peculiar and common characteristics that could be an advantage for these bacteria during the infection process.
