A recent publication in Porcine Health Management by April Estrada, from the Gebhart lab at the University of Minnesota, proposes new virulence-associated genes to predict the pathogenicity of US Streptococcus suis. This project continues her previous work on the classification of US S. suis strains based on pathotypes.Continue reading “Streptococcus suis: predicting pathogenicity with virulence-associated genes?”
- Streptococcus suis isolates were classified into 20 different serotypes and 58 different Sequence types (ST)s.
- Serotypes 1 and 1/2 were associated with higher pathogenic frequency, while ST profiles 1 and 28 were associated with higher frequency of pathogenic isolates.
- The analysis of the association between pathotype, serotype, and ST showed that overall, STs were a better predictor of pathogenicity than serotypes.
PhD candidate April Estrada, working with Drs. Gebhart and Marthaler published an open-access article on Streptococcus suis in the Journal of Clinical Microbiology. Streptococcus suis is an older pathogen but its prevalence as well as its virulence have been rising lately. This study investigates if categorizing isolates into serotypes and genotypes could help predict the severity of the disease on the farm.Continue reading “Can Streptococcus suis genotype predict its pathogenicity?”
In this article written for the National Hog Farmer, PhD candidate April Estrada describes the high diversity of Streptococcus suis (S.suis) isolates.Continue reading “Distribution of pathogenic Streptococcus suis in the US”
