Use of artificial neural networks and a gamma-concept-based approach to model growth of and bacteriocin production by streptococcus macedonicus ACA-DC 198 under simulated conditions of Kasseri Cheese production

Article Abstract:

A kinetic study was conducted to investigate the influence of temperature, pH, and salt concentration conditions prevailing during Kasseri cheese production on the growth of Streptococcus macedonicus ACA-DC 198, as well as on the production of macedocin. The results showed that artificial neural networks (ANNs), though less suitable for biological interpretation, outperform a more traditional model based on the gamma concept in describing the growth behavior and bacteriocin production capacity of S. mecadonicus ACA-DC 198.

Prevalence of Streptococcus suis genotypes in wild boars of Northwestern Germany

Article Abstract:

A study was conducted to investigate the prevalence of potentially human-pathogenic Streptococcus suis strains in wild boars, which cause meningitis in pigs and humans. The results suggest that at least 10% of wild boars in Northwestern Germany carry Streptococcus suis strains that are potentially virulent in humans.
